Left Image: James Stewart, Screenshot from the original 1958 theatrical trailer for the film Vertigo courtesy of Wikimedia commons. A Case Report Jim, a 34 year old accountant from Britain, arrived in my office complaining of low testosterone symptoms of low libido, erectile dysfunction, chronic fatigue, and mood disorder. A previous blood panel revealed a low testosterone level (242 ng/dl), low LH (1.6 iu/L) and FSH (1.7 iu/L). Preserving Fertility Jim had been married 5 years, and together with his wife, had a 2 year old daughter. For younger males who wish to expand their families, testosterone replacement is not advisable, since this interferes with fertility. Clomid Stimulation Test Failure In the past, Jim had seen an internist, a hematologist, an endocrinologist, and and few more specialist doctors. One of them had given Jim a trial of Clomiphene, (Clomid) 25 mg a day for 3 weeks, and a repeat lab panel showed no increase in either testosterone or LH/FSH levels. This is Clomid Stimulation Test failure, indicating Clomid is not a suitable treatment. Jim's previous doctor gave up in frustration, and Jim wanted to know, "What's next?". Next - Rule out a Pituitary Lesion with MRI Scan The next thing is an MRI scan of the pituitary gland and brain to rule out a pituitary lesion. This was done and the MRI scan was normal. Hypothalamic Dysfunction - Chronic Fatigue The Clomid Stimulation Test is one of the best methods for evaluating hypothalamic function (8). The failed Clomid Stimulation Test is virtually diagnostic of hypothalamic dysfunction, representing a complex condition with dysfunction of all hormonal systems in the body.(8) There is typically a blunted response to ACTH, low adrenal function, and a paradoxically low TSH in spite of low thyroid function, all associated with chronic fatigue. Jim's Medical History - Recreational Drug Use Jim told his story of many years of markedly reduced libido, anxiety, panic attacks, and chronic fatigue unrelieved by sleep. Jim's symptoms started about 10 years ago in his late 20's during which time he was living in London, going to school during the week, and on weekends, "clubbing" with his friends which meant recreational drug use with Ecstasy (MDMA), virtually every weekend for five years. Left image: Dancing at a nightclub ("clubbing"). 2006. Clubbing on Ecstasy Courtesy of Wikimedia Commons Generation E and Hypothalamic Dysfunction (12-20) Ecstasy (MDMA) is a chemically modified synthetic amphetamine drug that floods the brain with serotonin and dopamine, the two major neurotransmitters. This produces an intensely pleasurable effect, with 800% increase in cortisol levels on the dance floor while "clubbing" on Ecstasy.(18) Long term MDMA use shows damage to the serotonergic terminal axonal nerves in the hypothalamus. (14-16) These important nerve axons are responsible for pituitary signalling which controls endocrine function. This damage may or may not be reversible.(5,12-20) The Agony of Ecstasy - Inhibition of the Hypothalamic Neurosecretory System Animal studies show that hypothalamic gonadotropin levels are suppressed in the context of low testosterone suggesting that the hypothalamic neurosecretory system "is a primary target" of inhibition by MDMA usage.(24) Left image : Ecstasy (MDMA) Tablets, Courtesy of the DEA and WIkimedia Commons. Examination of brain photomicrographs of monkeys given MDMA reveals loss of serotonergic axons in the hypothalamus, with some abnormalities persisting for seven years. (25) Years of Weekend "Clubbing" and "Raves" with the recreational use of Ecstasy has created an entire generation, called Generation E.(12-20). Many of these Post-MDMA, post-Ecstasy members of Generation E are now suffering from low testosterone and other symptoms of hypothalmic dysfunction with chronic fatigue and fibromyalgia. They may find it difficult to find a physician who has the knowledge and experience to help them. Long Term SSRI Anti depressants and Hypothalamic Damage As noted by Michael H. Baumann in the January 2007 issue of Psychopharmacology (20), many studies have examined long term use of SSRI antidepressants such as Prozac, Paxil, Zoloft, Celexa, Effexor, paroxetine, sertraline etc, and have suggested that hypothalamic damage may be induced by SSRIs which may mimic that of MDMA(20). MDMA, the Turbo SSRI Upper image: Chemical structure of MDMA, Courtesy of Michael H. Baumann in Psychopharmacology (Berl). 2007 January; 189(4): 407–424. The drug, Ecstasy (MDMA) has been described by some as "a turbo SSRI ". (13) It is clear that MDMA has more potent immediate effects and produces long term adverse effects than SSRI antidepressants. Nonetheless, long term SSRI antidepressant use can potentially induce the same neuronal defects and chronic brain changes as those found with MDMA usage.(20) The reality is that many drugs cause hypothalamic dysfunction, including opiates, alcohol, anti-psychotics, and even inhaled or topical corticosteroids. There are many others.(21) (8) Polypharmacy and Hypothalamic Dysfunction In my office practice, we will frequently see patients on multiple psychoactive drugs prescribed by the primary care physician, internist or psychiatrist. This is a perfect example of an abusive medical practice that should be halted, and reveals a medical system gone wrong. Many of these unfortunate victims are on combinations of drugs such as SSRI antidepressants, amphetamines (Vyvanse ,lisdexamfetamine, Adderal, Ritalin) and Benzodiazapines (Xanax, Klonopin) and Narcotics such as Oxycontin and Vicodin, etc. Some are also chronic alcohol abusers. These patients arrive at my door with a form of "Burn Out", and drug-induced hypothalamic dysfunction characterized by chronic fatigue unrelieved by sleep. Recovery requires a gradually tapering of the drug dosage to "wean off" the psycho-active drug in order to min imize withdrawal effects. In some cases, a drug rehabilitation facility is required during the drug withdrawal phase. Treatment of Hypothalamic Dysfunction Jim's hormonal defects are more complicated than isolated low testosterone and require a treatment program as described by Jacob Teitelbaum MD (22) and Kent Holtorf MD (1-4) in their excellent books and articles covering chronic fatigue and hypothalamic dysfunction.(1-4, 22) Adrenal Axis Dr Holtorf's articles on hypothalamic dysfunction and chronic fatigue discuss the use low dose cortisol, usually given in doses less than 15 mg per day. In addition, Florinef, Fludrocortisone, 50 mcg, a day may be used.(1-2) A widely used nutritional supplement program for adrenal fatigue is described by Chris Miletis in the 2005 Townsend Letter (3) . This program includes Vitamin C, Pantethine (B5) and adaptogenic herbs.(3) ACTH Stimulation, Metyrapone Test, Clomid Test Endocrinologists commonly use the ACTH stimulation test to diagnose adrenal insufficiency. The ACTH stimulaton test is limited and does not evaluate the HPA axis. A better testing choice is the Metyrapone test. Unlike ACTH which requires an injection, the metyrapone drug can be given PO (orally). The metyrapone test is superior to the ACTH stimulation test because evaluates both hypothalamic and adrenal function.(4) However, in my opinion, the Clomid stimulation test is by far the best test for evaluating hypothalamic function. In agreement is Eugene Shippen MD in his comment posted here(8). Thyroid Axis A paradoxically low TSH level accompanied by low thyroid hormone levels (Free T3 levels less than 270 ) may indicate low thyroid function from hypothalamic dysfunction. (1-2) HCG and Gonadal Axis Treatment. The low testosterone level can be successfully treated with an LH analog called HCG (human chorionic gonadotropin) readily available at most pharmacies. HCG stimulates testicular production of testosterone without impairing fertility, and is therefore a preferred treatment in the younger age group. Jim's Treatment Program Shortly after starting the HCG injections, Jim reported an immediate improvement in mood, energy and libido. Repeat labs showed a rising testosterone level of 687 ng/dl. Jim's treatment program also included 15 mg hydrocortisone and 50 mcg Florinef daily. He was also given a small dosage of natural thyroid , a half grain tablet daily. Additional treatment protocols were also given as outlined by Dr. Jacob Teitelbaum in his books and articles (22). What is Happening in this Patient ? Jim had hypothalamic damage from MDMA drug use which caused his low hormone levels and chronic fatigue. Image left: Pituitary feedback control of LH, FSH and Testosterone from Estrogen (E2). Diagram is courtesy of Dr Rochira , Eur J Endocrinol. 2006 Oct;155(4):513-22.(1) Normally, the hypothalamus produces gonadotropin releasing hormone (GnRH), which in turn stimulates pituitary production of LH and FSH (leutinizing hormone and follicle stimulating hormone). LH and FSH then travel to the testicle to stimulate testosterone(LH) and sperm production (FSH). Chronic recreational drug use with Ecstasy. also called MDMA, damages Hypothalamic GNRH neurons (see above diagram upper center ).(14-16) With hypothalamic damage and dysfunction, there is absent or severely reduced GnRH release, and no stimulation for pituitary release of LH and FSH. Jim's treatment is HCG, an LH analog which stimulates testosterone production at the level of the end organ. This article is part two of a series, click here for part one.

As a result, patients often have multiple hormonal deficiencies 4-21, including thyroid, growth hormone and cortisol. Instead of T4 normally converting intracellularly to the active T3 in peripheral tissue, T4 is preferentially converted to reverse T3. Therefore, increasing levels of rT3 and diminishing levels of T3 are indicators of low tissue thyroid effect. Free T3 and rT3 tests can be ordered at most major clinical laboratories. A free T3/rT3 ratio that’s less than 2 pg/ng is consistent with low tissue thyroid activity. ------------------ 3) http://www.encognitive.com/files/The Naturopathic Approach to Adrenal Dysfunction.pdf The Naturopathic Approach to Adrenal Dysfunction by Jason Barker, ND and Chris Meletis, ND Townsend Letter Feb March 2005 Metyrapone Test 4) www.ncbi.nlm.nih.gov/pubmed/8013141 Overnight Metyrapone Test - Clin Endocrinol (Oxf). 1994 May;40(5):603-9.

Source Department of Endocrinology and Diabetes Mellitus, St Vincent's Hospital, Dublin, Ireland. Abstract OBJECTIVE: The ACTH stimulation test examines adrenal responsiveness but may not examine the entire hypothalamic-pituitary-adrenal (HPA) axis and requires parenteral administration. The cortisol response to hypoglycaemia provides an index of activity of the entire HPA axis but is demanding for patients and medical staff. The aim of the present study was to examine the performance of the overnight single-dose metyrapone test as it provides a simple alternative test for HPA axis function. DESIGN: Audit of the overnight metyrapone test performed in one centre between 1979 and 1991. PATIENTS: Three hundred and ninety-eight patients underwent 576 tests. Comparisons between the responses to metyrapone and the ACTH stimulation test and of the responses to metyrapone and insulin induced hypoglycaemia test were possible in 87 and 17 patients respectively. MEASUREMENTS: Following the midnight administration of metyrapone tablets, 30 mg/kg orally, blood samples were obtained between 0800 and 0930 h for radioimmunoassay of both 11-deoxycortisol and cortisol. RESULTS: Five hundred and seventy-six metyrapone tests were performed on 398 patients with no serious side-effects encountered. Adrenal insufficiency was diagnosed in 105 patients. Of these, 18 had a primary adrenal disorder and 87 had a disorder of the hypothalamic-pituitary unit. One hundred per cent concordance between the metyrapone, the ACTH and the hypoglycaemia test was seen in patients with primary adrenal insufficiency. CONCLUSION: Since the metyrapone test gives similar information about hypothalamic-pituitary axis function as does the hypoglycaemia test, we recommend the use of the overnight metyrapone test as a safe, simple and reliable index of the hypothalamic-pituitary axis integrity. The ACTH stimulation test should not be used for patients suspected of having secondary adrenal insufficiency. ------------------------------------------------- 5) www.ncbi.nlm.nih.gov/pubmed/9629295 141.213.232.243/bitstream/handle/2027.42/74817/j.1749-6632.1998.tb09607.x.pdf ;jsessionid=28BBED7879D532D6155B4135EBBB8963?sequence=1 Ann NY Acad Sci. 1998 May 1;840:684-97. Evidence for and pathophysiologic implications of hypothalamic-pituitary-adrenal axis dysregulation in fibromyalgia and chronic fatigue syndrome. Demitrack MA, Crofford LJ. Source Lilly Research Laboratories, Lilly Corporate Center, Indianapolis, Indiana 46285, USA. Abstract Chronic fatigue syndrome (CFS) is characterized by profound fatigue and an array of diffuse somatic symptoms. Our group has established that impaired activation of the hypothalamic-pituitary-adrenal (HPA) axis is an essential neuroendocrine feature of this condition. The relevance of this finding to the pathophysiology of CFS is supported by the observation that the onset and course of this illness is excerbated by physical and emotional stressors. It is also notable that this HPA dysregulation differs from that seen in melancholic depression, but shares features with other clinical syndromes (e.g., fibromyalgia). How the HPA axis dysfunction develops is unclear, though recent work suggests disturbances in serotonergic neurotransmission and alterations in the activity of AVP, an important co-secretagogue that, along with CRH, influences HPA axis function. In order to provide a more refined view of the nature of the HPA disturbance in patients with CFS, we have studied the detailed, pulsatile characteristics of the HPA axis in a group of patients meeting the 1994 CDC case criteria for CFS. Results of that work are consistent with the view that patients with CFS have a reduction of HPA axis activity due, in part, to impaired central nervous system drive. These observations provide an important clue to the development of more effective treatment to this disabling condition. ------------------------- 6) edrv.endojournals.org/content/24/2/236.long Endocrine Reviews April 1, 2003 vol. 24 no. 2 236-252 The Neuroendocrinology of Chronic Fatigue Syndrome A.

Source Department of Psychiatry, University Hospital Antwerp, Edegem, Belgium. Abstract There is evidence for a hypofunction of the hypothalamic-pituitary-adrenal (HPA) axis in a proportion of the patients with chronic fatigue syndrome (CFS), despite the negative studies and methodological difficulties. In this review, we focus on challenge studies and on the role of the HPA axis in the pathogenesis of CFS. Mild hypocortisolism, blunted adrenocorticotropin response to stressors and enhanced negative feedback sensitivity to glucocorticoids are the main findings. Several underlying mechanisms have been proposed. Currently, it is a matter of debate whether these disturbances have a primary role in the pathogenesis of CFS. However, even if the HPA axis dysfunctions are secondary to other factors, they are probably a relevant factor in symptom propagation in CFS. The fatigue must be accompanied by at least 4 or more of the following case-defining symptoms during at least 6 months of consecutive illness: sore throat, tender cervical or axillary lymph nodes, muscle pain, multijoint pain, postexertional malaise, unrefreshing sleep, headaches and impaired memory or concentration --------------------------------------------------------------------- Clomiphene test for hypothalamic dysfunction 8) www.endocrinetoday.com/comments.aspx?rid=30573 Comment by Eugene Shippen MD -- September 19, 2008 09:12 AM I totally agree with the author that diagnosis should established before treatment. A short clomiphene stimulation test (clomiphene 25-50mg daily for 7 days followed by FSH/LH testosterone and estradiol) has been forgotten by most clinicians and is absent from most current "Guidelines." A robust response which I frequently find insures that the hypogonadism is NOT due to hypothalamic dysfunction that may be due to drugs, disease, lifestyle, alcohol, stress, depression, aging, etc. Clomiphene testing evaluates both hypothalamic and testicular responses and may lead to most thorough evaluation of the HP axis. The use of low dose clomiphene 10-25 mg 3xweekly in cases with robust response frequently is effective without the need for full testosterone replacement and is sometimes only needed for temporary treatment until the underlying causes are corrected (drugs that suppress testosterone changed, lifestyle improved, alcohol stopped, etc.). Clomiphene has been successfully used in the Lahey Clinic for sexual dysfunction in borderline low testosterone cases (Andre Guay references) ---------------------------------- 9) www.uthsc.edu/endocrinology/documents/ch08-syllabus-Childress.pdf PATHOPHYSIOLOGY COURSE - ENDOCRINE MODULE Male Gonadal Disorders (Testicular Disorders & Clinical Conferences) Dale Childress, MD Monday, December 6, 2010, 8:00-8:50am Written by: Jeffrey R.

Urology [1991, 38(4):317-322] Effect of raising endogenous testosterone levels in impotent men with secondary hypogonadism: double blind placebo-controlled trial with clomiphene citrate. Twenty-one men with erectile complaints who were found to have a low level of serum testosterone without a reciprocal elevation of the serum levels of luteinizing hormone were evaluated to identify whether the defect was of hypothalamic or of pituitary origin. Patients underwent a luteinizing hormone (LH)-follicle-stimulating hormone (FSH)-releasing hormone stimulation test that showed a normal but sluggish increase in LH and FSH levels, thus ruling out a pituitary defect and suggesting a suprapituitary abnormality. This was confirmed when, in response to clomiphene, patients had a normal increase in gonadotropin and testosterone levels. Although the basal as well as clomiphene and gonadotropin releasing hormone-stimulated levels of total testosterone and gonadotropins were identical in men less than and more than fifty years old, the elevation of free testosterone levels in response to clomiphene was higher in patients younger than fifty. This suggested that although the primary abnormality found in these patients is altered secretion of gonadotropin hormone-releasing hormone from the hypothalamus, an age-related decline in the responsivity of Leydig cells to LH may make it more manifest in older patients. Elevation of testosterone levels from a subnormal to a normal range in response to clomiphene administered for seven days suggests that the defect is functional and reversible and that the drug may be useful in treatment of sexual dysfunction in this group of patients. --------------------------------- 11) www.ncbi.nlm.nih.gov/pubmed/12904801 http://www.nature.com/ijir/journal/v15/n3/full/3900981a.html (full text) Int J Impot Res. 2003 Jun;15(3):156-65. Clomiphene increases free testosterone levels in men with both secondary hypogonadism and erectile dysfunction: who does and does not benefit? Guay AT, Jacobson J, Perez JB, Hodge MB, Velasquez E. Source Center for Sexual Function (Endocrinology), Peabody, Massachusetts 01960, USA. Abstract Secondary hypogonadism is more common than primary gonadal failure and is seen in chronic and acute illnesses. Although testosterone has a role in erections, its importance in erectile dysfunction (ED) has been controversial. Hypogonadism produced by functional suppression of pituitary gonadotropins has been shown to correct with clomiphene citrate, but with a modest effect on sexual function. We wondered if longer treatment would produce improved results. A total of 178 men with secondary hypogonadism and ED received clomiphene citrate for 4 months. Sexual function improved in 75%, with no change in 25%, while significant increases in luteinizing hormone (P<0.001) and free testosterone (P<0.001) occurred in all patients. Multivariable analysis showed that responses decreased significantly with aging (P<0.05). Decreased responses also occurred in men with diabetes, hypertension, coronary artery disease, and multiple medication use. Since these conditions are more prevalent with aging, chronic disease may be a more important determinant of sexual dysfunction. Men with anxiety-related disorders responded better to normalization of testosterone. Assessment of androgen status should be accomplished in all men with ED. For those with lower than normal age-matched levels of testosterone treatment directed at normalizing testosterone with clomiphene citrate is a viable alternative to giving androgen supplements. ----- Clubbing in London 12) blogs.telegraph.co.uk/news/damianthompson/100161244/class-a-clubbing-drugs-your-children-are-taking-them-and-theyre-here-to-stay/ Class A clubbing drugs: your children are taking them and they're here to stay By Damian Thompson Health and lifestyle Last updated: May 29th, 2012 13) www.maps.org/media/esquire_july2012_ecstasy.pdf MDMA is like a turbo SSRI — it doesn’t just block the transporter, it! reverses the process and floods the!brain with!serotonin.

Neuropsychotoxicity of abused drugs: molecular and neural mechanisms of neuropsychotoxicity induced by methamphetamine, 3,4-methylenedioxymethamphetamine (ecstasy), and 5-methoxy-N,N-diisopropyltryptamine (foxy). Nakagawa T, Kaneko S. Source Department of Molecular Pharmacology, Graduate School of Pharmaceutical Sciences, Kyoto University, Yoshida, Sakyo-ku, Kyoto, Japan. Abstract Psychostimulants including amphetamines and cocaine, opioids including morphine, and some recreational drugs share the ability to cause drug dependence and addiction. Although these drugs of abuse primarily act on distinct molecular targets, such as monoamine transporters or receptors, they finally converge to common neural pathways. Several lines of evidence suggest that their chronic treatment leads to the enhancement of the mesocorticolimbic dopaminergic neurons from the ventral tegmental area (VTA) to the nucleus accumbens (NAc) and the medial prefrontal cortex (mPFC) and leads to abnormal glutamatergic function from the mPFC to the NAc and VTA. The neural adaptation of dopaminergic-glutamatergic system is considered to be critically implicated in neuropsychotoxic effects of these drugs of abuse. In addition, recent studies suggest that the serotonergic neurons from the raphe nuclei to limbic areas modulate the mesocorticolimbic dopaminergic-glutamatergic system and participate in the neuropsychotoxicity. In this review, our recent in vitro studies on the molecular targets and neural adaptation of methamphetamine, 3,4-methylenedioxymethamphetamine (MDMA, "ecstasy"), and 5-methoxy-N,N-diisopropyltryptamine (5-MeO-DiPT, "foxy") using Xenopus oocytes, organotypic slice cultures of the mesocorticolimbic dopaminergic-glutamatergic system, and the raphe serotonergic system are introduced. Unlike amphetamines or cocaine, MDMA primary acts on SERT as a substrate, rather than DAT and norepinephrine transporter (2). MDMA causes acute efflux of 5-HT from serotonergic neurons through SERT and leads to a long-term depletion of 5-HT that correlates with destruction of serotonergic nerve Fig. 2.

Cortisol and 3,4-Methylenedioxymethamphetamine: Neurohormonal Aspects of Bioenergetic Stress in Ecstasy Users A.C. Parrott* 3,4-Methylenedioxymethamphetamine (MDMA) can affect both neurotransmitter and neurohormonal activity. Cortisol release is increased by stimulatory factors, including physical activity, thermal stress and stimulant drugs. In laboratory studies MDMA leads to an acute cortisol increase of around 150% in sedentary humans. In MDMA-using dance clubbers, the cortisol levels are increased by around 800%, possibly due to the combined factors of stimulant drug, physical exertion and psychosocial stimulation. Regular ecstasy/MDMA users also demonstrate changes in baseline cortisol levels and cortisol reactivity, with compromised hypothalamic-pituitary-adrenal activity. Nonpharmacological research has shown how cortisol is important for psychological aspects such as memory, cognition, sleep, impulsivity, depression and neuronal damage. Conclusions: The energizing hormone cortisol is involved in the psychobiology of MDMA, probably via its effects on energy metabolism. Acute cortisol release may potentiate the stimulating effects of MDMA in dance clubbers. Chronically, cortisol may contribute to the variance in functional and structural consequences of repeated ecstasy usage. Dance clubbing on ecstasy/MDMA led to an 800% group increase in saliva cortisol, significantly higher than both baseline and dance clubbing during abstinence (fig. (fig.1).1). Gerra et al. [88] noted that the baseline cortisol levels were significantly lower in drug-free ecstasy users compared to controls, along with significantly reduced cortisol responses to a psychosocial stressor. The authors concluded: ‘HPA basal hyperactivation and reduced responsiveness to stress, may represent a complex neuroendocrine dysfunction associated with MDMA use.’ ---------------------- 19) www.alternet.org/story/10482/the_ecstasy_generation The Ecstasy Generation - Slowly but surely, Ecstasy is becoming the drug of choice for the millennial era.

Rothman Clinical Psychopharmacology Section, Intramural Research Program (IRP), National Institute on Drug Abuse (NIDA), National Institutes of Health (NIH), 5500 Nathan Shock Drive, Baltimore, MD 21224 USA Michael H. Baumann MDMA targets monoamine transporters, and transporter-mediated release of 5-HT, DA, and NE underlies pharmacological effects of the drug. Consistent with in vitro results, in vivo microdialysis experiments demonstrate that MDMA increases extracellular 5-HT and DA in rat brain, with effects on 5-HT being greater in magnitude Neuroendocrine effects of MDMA include secretion of prolactin from the anterior pituitary and corticosterone from the adrenal glands (Nash et al. 1988). Evidence indicates that these MDMA-induced hormonal effects are mediated via postsynaptic 5-HT2 receptors in the hypothalamus, which are activated by released 5-HT. Long Term Adverse Effects of MDMA The long-term adverse effects of MDMA on 5-HT systems have attracted substantial interest because studies in rats and nonhuman primates show that high-dose MDMA administration produces persistent reductions in markers of 5-HT nerve terminal integrity [reviewed by Lyles and Cadet (2003); Sprague et al. (1998)]. Table 2 summarizes findings of investigators who first demonstrated that MDMA causes long-term (>1 week) inactivation of tryptophan hydroxylase activity, depletions of brain tissue 5-HT, and reductions in SERT binding and function (Battaglia et al. 1987; Commins et al. 1987; Schmidt 1987; Stone et al. 1987). These serotonergic deficits are observed in various regions of rat forebrain, including frontal cortex, striatum, hippocampus, and hypothalamus. Immunohistochemical analysis of 5-HT in cortical and subcortical areas reveals an apparent loss of 5-HT axons and terminals in MDMA-treated rats, especially the fine-diameter projections arising from the dorsal raphe nucleus (O’Hearn et al. 1988). Moreover, 5-HT axons and terminals remaining after MDMA treatment appear swollen and fragmented, suggesting structural damage. Long term Damage of MDMA similar to SSRI s Chronic administration of 5-HT selective reuptake inhibitors (SSRIs), like paroxetine and sertraline, leads to a marked loss of SERT binding and function comparable to MDMA, but these agents are therapeutic drugs rather than neurotoxins (Benmansour et al. 1999; Frazer and Benmansour 2002). Finally, high-dose administration of SSRIs produces swollen, fragmented, and abnormal 5-HT terminals, which are indistinguishable from the effects of MDMA and other substituted amphetamines (Kalia et al. 2000). 5-HT neurons projecting to the hypothalamus provide stimulatory input for the secretion of adrenocorticotropin (ACTH) and prolactin from the anterior pituitary (Van de Kar 1991). Accordingly, 5-HT releasers (e.g., fenfluramine) and 5-HT receptor agonists increase plasma levels of these hormones in rats and humans MDMA can produce persistent increases in anxiety-like behaviors without measurable 5-HT deficits suggests that even moderate doses may pose risks. -------------------- 21) home.comcast.net/~staticnrg/Cushings/HPA_Drugs.pdf (full pdf file) http://www.ncbi.nlm.nih.gov/pubmed/18404384 Pituitary. 2008;11(2):219-29.

The recreational drug ecstasy disrupts the hypothalamic-pituitary-gonadal reproductive axis in adult male rats. Dickerson SM, Walker DM, Reveron ME, Duvauchelle CL, Gore AC. Division of Pharmacology and Toxicology, The University of Texas at Austin Reproductive function involves an interaction of three regulatory levels: hypothalamus, pituitary, and gonad. The primary drive upon this system comes from hypothalamic gonadotropin-releasing hormone (GnRH) neurosecretory cells, which receive afferent inputs from other neurotransmitter systems in the central nervous system to result in the proper coordination of reproduction and the environment. Here, we hypothesized that the recreational drug (+/-)-3,4-methylenedioxymethamphetamine (MDMA; 'ecstasy'), which acts through several of the neurotransmitter systems that affect GnRH neurons, suppresses the hypothalamic-pituitary-gonadal reproductive axis of male rats. Adult male Sprague-Dawley rats self-administered saline or MDMA either once (acute) or for 20 days (chronic) and were euthanized 7 days following the last administration. We quantified hypothalamic GnRH mRNA, serum luteinizing hormone concentrations, and serum testosterone levels as indices of hypothalamic, pituitary, and gonadal functions, respectively. The results indicate that the hypothalamic and gonadal levels of the hypothalamic-pituitary-gonadal axis are significantly altered by MDMA, with GnRH mRNA and serum testosterone levels suppressed in rats administered MDMA compared to saline. Furthermore, our finding that hypothalamic GnRH mRNA levels are suppressed in the context of low testosterone concentrations suggests that the central GnRH neurosecretory system may be a primary target of inhibitory regulation by MDMA usage. 25) http://www.jneurosci.org/content/19/12/5096.long http://www.ncbi.nlm.nih.gov/pubmed/10366642?dopt=Abstract J Neurosci. 1999 Jun 15;19(12):5096-107. Altered serotonin innervation patterns in the forebrain of monkeys treated with (+/-)3,4-methylenedioxymethamphetamine seven years previously: factors influencing abnormal recovery. by Hatzidimitriou G, McCann UD, Ricaurte GA. Department of Neurology, The Johns Hopkins Medical Institutions, Baltimore, Maryland 21205, USA. The recreational drug (+/-)3,4-methylenedioxymethamphetamine (MDMA, "Ecstasy") is a potent and selective brain serotonin (5-HT) neurotoxin in animals and, possibly, in humans. The purpose of the present study was to determine whether brain 5-HT deficits persist in squirrel monkeys beyond the 18-month period studied previously and to identify factors that influence recovery of injured 5-HT axons. Seven years after treatment, abnormal brain 5-HT innervation patterns were still evident in MDMA-treated monkeys, although 5-HT deficits in some regions were less severe than those observed at 18 months. No loss of 5-HT nerve cell bodies in the rostral raphe nuclei was found, indicating that abnormal innervation patterns in MDMA-treated monkeys are not the result of loss of a particular 5-HT nerve cell group. Factors that influence recovery of 5-HT axons after MDMA injury are (1) the distance of the affected axon terminal field from the rostral raphe nuclei, (2) the degree of initial 5-HT axonal injury, and possibly (3) the proximity of damaged 5-HT axons to myelinated fiber tracts.
