TY - JOUR. T1 - Acute Amino Acid d -Serine Administration, Similar to Ketamine, Produces Antidepressant-like Effects through Identical Mechanisms. AU - Wei, I. Hua. AU - Chen, Kuang Ti. AU - Tsai, Mang Hung. AU - Wu, Ching Hsiang. AU - Lane, Hsien Yuan. AU - Huang, Chih Chia. PY - 2017/12/13. Y1 - 2017/12/13. N2 - d-Serine is an amino acid and can work as an agonist at the glycine sites of N-methyl-d-aspartate receptor (NMDAR). Interestingly, both types of glutamatergic modulators, NMDAR enhancers and blockers, can improve depression through common targets, namely alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionaic acid receptors (AMPARs) and mammalian target of rapamycin (mTOR). To elucidate the cellular signaling pathway underlying this counterintuitive observation, we activated NMDARs in rats by using d-serine. Saline, ketamine (NMDAR antagonist), and desipramine (tricyclic antidepressant) were used as controls. The antidepressant-like effects of all agents were evaluated using the forced ...

TY - JOUR. T1 - Carbamoylated erythropoietin produces antidepressant-like effects in male and female mice. AU - Sampath, Dayalan. AU - McWhirt, Joshua. AU - Sathyanesan, Monica. AU - Newton, Samuel S.. PY - 2020/1/10. Y1 - 2020/1/10. N2 - Major depressive disorder and related illnesses are globally prevalent, with a significant risk for suicidality if untreated. Antidepressant drugs that are currently prescribed do not benefit 30% of treated individuals. Furthermore, there is a delay of 3 or more weeks before a reduction in symptoms. Results from preclinical studies have indicated an important role for trophic factors in regulating behavior. Erythropoietin (Epo), which is widely prescribed for anemia, has been shown to produce robust neurotrophic actions in the CNS. Although Epos antidepressant activity has been successfully demonstrated in multiple clinical trials, the inherent ability to elevate RBC counts and other hematological parameters preclude its development as a mainstream CNS drug. A ...

A study of older suicide victims by researchers at Weill Cornell Medical College in New York has found that very few of them - less than a quarter - were taking antidepressants at the time of their death. The study of 255 suicide victims who were all over 65 and who killed themselves between 2001 and 2004 found that only 23% of the sample had been taking antidepressants at the time of their death. Only 16.7% of those over 85 had been taking antidepressants ...

The mechanism underlying the therapeutic effect of antidepressants is not known but neuroadaptive processes akin to long-term potentiation have been postulated. Arc (Activity-regulated, cytoskeletal-associated protein) is an effector immediate early gene implicated in LTP and other forms of neuroplasticity. Recent data show that Arc expression is regulated by brain 5-hydroxytryptamine neurones, a target of many antidepressants. Here in situ hybridisation and immunohistochemistry were used to examine whether Arc expression in rat brain is altered by antidepressant drug treatment. Repeated administration of the monoamine reuptake inhibitors paroxetine, venlafaxine or desipramine induced region-specific increases in Arc mRNA. These increases were greatest in regions of the cortex (frontal and parietal cortex) and hippocampus (CA1 layer) and absent in the caudate putamen. Repeated treatment with the monoamine oxidase inhibitor, tranylcypromine, increased Arc mRNA in a similar fashion to the monoamine

This study suggested that living alone is associated with the prospective use of antidepressant medication in a nationally representative Finnish working-age sample. Those who lived alone had an 80% higher risk of initiating antidepressant use during the 7-year follow-up compared with participants who did not live alone. Socioeconomic adversity explained part of this relationship, especially in women. Psychosocial factors, including a lack of social support, were important explanatory factors in men. Health behaviors had only a marginal contribution to the association between living alone and antidepressant use among men and women, with the exception of heavy alcohol use in men. This is in agreement with a previous register-based study showing a strong link between living alone and alcohol-related mortality [36]. All the factors included in this study explained 46% of the associations, thus leaving the majority of the association between living alone and antidepressant use unexplained.. Our ...

Dont be surprised if a doctor prescribes an antidepressant medication to treat a condition totally unrelated to depression. Certain medical conditions and/or the symptoms caused by them are responding well to treatment with antidepressant medications. These are a few conditions for which a patient might be prescribed an antidepressant medication and why the medication works for these conditions.. Cymbalta (Duloxetine) Helps Ease Diabetic Nerve Pain. The antidepressant medication, Cymbalta, helps ease the pain of diabetic peripheral neuropathy and other chronic pain that some diabetics experience. The antidepressant medication works by adjusting the chemical response the brain is receiving regarding the nerve pain being felt. The chemical adjustment allows the pain to be perceived as less severe so the diabetic peripheral neuropathy eases in severity.. Prozac (Fluoxetine) Helps Prevent Binge Eating. Patients with an eating disorder that causes them to binge eat are often prescribed the ...

Vascular endothelial growth factor (VEGF) is a key player in the pathogenesis of neovascular age-related macular degeneration (nAMD) and is also involved in the final common pathway of antidepressant medication. This study investigated the relationship between the need for anti-VEGF retreatment in patients with nAMD and antidepressant medication, and the potential impact of ocular structural factors. Data from two identical prospective 2-year treatment protocols using ranibizumab or aflibercept in a variable-dosing regimen (Observe-and-Plan) were analysed. Retreatment requirement was compared with antidepressant medication intake (primary outcome) and a variety of ocular factors from baseline and from month 3 response (secondary outcomes), using univariate and multivariate analyses. Of the 206 included patients (227 eyes), 19 were on antidepressant medication. Their nAMD eyes significantly more often had pigment epithelium detachment (PED, p=0.04). Multivariate analysis revealed a si

Dysregulation of the glutamatergic system and its receptors in medial prefrontal cortex (mPFC) has been implicated in major depressive disorder. Recent preclinical studies have shown that enhancing NMDA receptor (NMDAR) activity can exert rapid antidepressant-like effects. AGN-241751, an NMDAR positive allosteric modulator (PAM), is currently being tested as an antidepressant in clinical trials, but the mechanism and NMDAR subunit(s) mediating its antidepressant-like effects are unknown. We therefore used molecular, biochemical, and electrophysiological approaches to examine the cell-type-specific role of GluN2B-containing NMDAR in mediating antidepressant-like behavioral effects of AGN-241751. We demonstrate that AGN-241751 exerts antidepressant-like effects and reverses behavioral deficits induced by chronic unpredictable stress in mice. AGN-241751 treatment enhances NMDAR activity of excitatory and parvalbumin-inhibitory neurons in mPFC, activates Akt/mTOR signaling, and increases levels of synaptic

Antidepressant initiation was more frequent among persons with Alzheimers disease already 9 years before the diagnosis than among comparison persons not diagnosed with Alzheimers disease. This finding was somewhat surprising. It may be related to more frequent treatment of depressive symptoms because depression has been associated with an increased risk of Alzheimers disease in previous studies.. Antidepressant use was investigated in the Finnish nationwide MEDALZ study from 9 years before until 4 years after the diagnosis of Alzheimers disease. The difference in antidepressant initiations persisted during the entire follow-up period. During the 13-year follow-up period, 42% of persons with Alzheimers disease and 22% of persons not diagnosed with the disease initiated antidepressant use. The most commonly used antidepressant group was selective serotonin reuptake inhibitor (SSRI) drugs, followed by mirtazapine.. The register-based study was based on 62,104 Finnish persons with Alzheimers ...

University of Adelaide researchers have found that women on antidepressant medication are more successful at breastfeeding their babies if they keep taking the medication, compared with women who quit antidepressants because of concerns about their babies health.. These results have been presented this week at the 18th Perinatal Society of Australia and New Zealand (PSANZ) Annual Conference in Perth.. Using data from the Danish National Birth Cohort in Denmark, researchers in the University of Adelaides Robinson Research Institute studied the outcomes of 368 women who were on antidepressants prior to becoming pregnant.. We found that two thirds of the women (67%) stopped taking their antidepressant medication either after becoming pregnant or during breastfeeding, says NHMRC Early Career Fellow Dr Luke Grzeskowiak from the Robinson Research Institute.. A third of the women (33%) continued to take antidepressant medication throughout their pregnancy and while breastfeeding, and these women ...

The problem of interest. Depression is a common serious illness, with great personal suffering and a 10% or more risk of suicide. There are two kinds of depression, bipolar (depression alternating with mood swings) and unipolar (simple depression, or major depressive disorder). In both kinds of depression, antidepressants are commonly used. However, unlike unipolar depression, where a good deal of research supports this use, there is very little research on antidepressant use in bipolar disorder. Some studies support benefit with antidepressants for bipolar depression; i.e., if one is depressed, antidepressants can help a patient get better in the short-term. However, long-term studies are limited; the few available studies with older antidepressants did not demonstrate long-term preventive benefit. Some clinicians think new generation antidepressants (like Prozac and other serotonin reuptake inhibitors) are safer and more effective than the older antidepressants. Yet there are no rigorous ...

BACKGROUND: Conventional meta-analyses have shown inconsistent results for efficacy of second-generation antidepressants. We therefore did a multiple-treatments meta-analysis, which accounts for both direct and indirect comparisons, to assess the effects of 12 new-generation antidepressants on major depression. METHODS: We systematically reviewed 117 randomised controlled trials (25 928 participants) from 1991 up to Nov 30, 2007, which compared any of the following antidepressants at therapeutic dose range for the acute treatment of unipolar major depression in adults: bupropion, citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, milnacipran, mirtazapine, paroxetine, reboxetine, sertraline, and venlafaxine. The main outcomes were the proportion of patients who responded to or dropped out of the allocated treatment. Analysis was done on an intention-to-treat basis. FINDINGS: Mirtazapine, escitalopram, venlafaxine, and sertraline were significantly more efficacious than duloxetine (odds ratios

New research published in the BMJ studies the association between antidepressant use during pregnancy and autism.. A roundup accompanied this analysis.. Title, Date of Publication & Journal. Antidepressants during pregnancy and autism in offspring: population based cohort study. Published: Wednesday 19 July. BMJ. Studys main claims - and are they supported by the data. The study claims there is a small association between antidepressant use in pregnancy and autism without intellectual disability. This claim is plausible given the evidence presented in the paper. The study finds no link between antidepressant use and autism with intellectual disability.. The study does not claim that antidepressant use causes autism, and there is no evidence in the paper to support such a claim.. Although the association is statistically robust, the number of children this affects is very small - around 1 in every 100 babies born to a mother on antidepressants. Additionally none of the excess cases of autism ...

While delayed onset of antidepressant action remains a shortcoming of current antidepressants, preliminary clinical data with newer antidepressants, including mirtazapine, show promise for a hastened onset. Several potential mechanisms have been postulated and investigated. Mirtazapine displays serotonin 5-HT2 and 5-HT3, receptor blocking properties, while its putative earlier onset of action is thought to be related to its 2-adrenoceptor lytic action (at 2-adrenergic autoreceptors and heteroreceptors), thereby modulating central serotonergic and noradrenergic neurotransmission. The current study investigated the role of 2-adrenoceptor antagonism for earlier onset of action in a rat model of depression. First of all, the treatment period necessary to produce antidepressant-like responses with fluoxetine (an antidepressant with a delayed onset of action) was established. Rats were treated for 3, 7, and 11 days with fluoxetine, whereafter the forced swim test (FST) was employed and ...

Patients with major depressive disorder (MDD), both adult and pediatric, may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressant medications, and this risk may persist until significant remission occurs. Suicide is a known risk of depression and certain other psychiatric disorders, and these disorders themselves are the strongest predictors of suicide. There has been a long-standing concern, however, that antidepressants may have a role in inducing worsening of depression and the emergence of suicidality in certain patients during the early phases of treatment. Patients with major depressive disorder (MDD), both adult and pediatric, may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressant medications, and this risk may persist ...

Psychiatrists most commonly prescribe antidepressants for bipolar depression, but mounting evidence shows that the traditional antidepressants that are effective in unipolar depression are not effective in bipolar disorder. At the 2013 meeting of the American Psychiatric Association, researcher Jessica Lynn Warner reported that among 377 patients with Bipolar I Disorder who were discharged from a hospital, those who were prescribed an antidepressant at discharge were just as likely to be remitted for a new depression than those not given an antidepressant.. The average time to readmission also did not differ across the two groups and was 205 +/- 152 days. Those patients prescribed the serotonin and norepinephrine reuptake inhibitor (SNRI) drug venlafaxine (Effexor) were three times more likely to be readmitted than those not prescribed antidepressants.. These naturalistic data (generated from observations of what doctors normally do and information in the hospitals clinical notes) resemble ...

Hello fellow fasters, I m taking 60mg of fluoxetine and 15mg of mirtazapine daily. My depression has become severe recently and I now realise that taking antidepressants is not going to help me long term so I ve reached a point where I have to try something different. I watched The science of fasting on YouTube and was intrigued and excited that water only fasting had had positive effects on mental health in a clinical setting. Since then I ve done a lot of research and found only one possible contraindication that applied to me: that I m on AD. I can t stop them cold turkey so af ...

National Institute of Mental Health. Depression is a serious disorder that can cause significant problems in mood, thinking, and behavior at home, in school, and with peers. It is estimated that major depressive disorder (MDD) affects about 5 percent of adolescents, who have more frequent suicidal thinking and behavior and greater likelihood of substance abuse than youth in general.. Research has shown that, as in adults, depression in children and adolescents can be treated. In particular, antidepressant medications - called selective serotonin reuptake inhibitors (SSRIs) because they specifically target the neurotransmitter serotonin - have been shown to be of benefit to children and adolescents with major depressive disorder. Certain types of psychological therapies have also been shown to be beneficial. In those with moderate to severe depression they are especially useful when combined with medication. Our knowledge of antidepressant treatments in youth, though growing substantially, ...

Given that both clinical and preclinical studies suggest that BDNF may be involved in the therapeutic action of antidepressants, BDNF appears to be a good candidate gene for the pharmacogenetic study of antidepressants. In our 2003 study on 110 MDD outpatients, we examined the association between the BDNF Val66Met polymorphism and response to 4-week antidepressant (fluoxetine) treatment.17 A trend (p=0.086) to higher total HAM-D-score percentage change was noted for the Val/Met-heterozygote patients in comparison to those bearing the homozygote (Val/Val or Met/Met). While similar findings have been reported in some of the subsequent studies of this polymorphism and the antidepressant response23,24, other studies demonstrated a better response in subjects with the Met variant25-27 or they found no association at all (Table 1).28,29 The inconsistencies in these findings might be due to the small sample sizes used in some of the studies. They could also have arisen as the result of differences in ...

Major depressive disorder (MDD) is one of the most common psychiatric disorders and its origin has been attributed to dysfunction of the monoamine systems, particularly noradrenergic and serotonergic, making them the main targets of the majority of antidepressants currently available. However a number of unmet clinical needs remain, such as a delay of several weeks from the first treatment to manifest antidepressant effects, low remission rates and high rates of relapse and recurrence. Fast acting antidepressant activity and efficacy in treatment-resistant cases has been reported with drugs that inhibit the glutamate N-methyl-D-aspartic acid (NMDA) receptor. However, this pharmacological approach is problematic, as it leads to motor and psychotic side effects. Inhibitors of nitric oxide synthase (NOS), a downstream target of NMDA receptors, produce antidepressant effects in the Porsolt test of antidepressant activity in laboratory rodents, without the adverse effects associated with NMDA ...

Marina Picciotto - Depression is a debilitating illness that is highly prevalent in the United States and up to 50% of patients with major depression are non:responsive to current antidepressant medications. Based on our basic science studies of the role of acetylcholine in pathways underlying depression:like behavior in rodents, our laboratory has identified nicotinic acetylcholine receptors (nAChRs) as a key target for development of novel antidepressant medications. We have established collaborations with a chemist (Dr. Daniela Gundisch, University of Hawaii) who has synthesized a number of new nicotinic partial agonists that target specific subtypes of nAChRs. In collaboration with an electrophysiologist (Dr. Roger Papke, University of Florida) we have characterized the selectivity of these compounds and our lab has shown that they are effective in animal models of antidepressant:efficacy. As a proof of principle, we have shown that nicotinic agents already approved for use in human subjects ...

By contrast, the risk of antidepressant treatment is small. A 2004 review by the Food and Drug Administration, analyzing clinical trials of the drugs, did show an elevated risk of suicidal thinking and nonlethal suicide attempts in young people taking antidepressants - 3.5 percent, compared with 1.7 percent of those taking a placebo. But since the lifetime risk of actual suicide in depressed people ranges from 2.2 to 12 percent, risk from treatment is dwarfed by the risks of the disease itself ...

Knowledge of how different antidepressants are likely to affect parameters of sleep can provide an important basis for selecting an appropriate antidepressant drug among the roughly 2 dozen marketed options to meet the needs of depressed patients. 1

Date Created: about 1998. Preface to old edition. Most of the SNRIs that have been on the market have failed to show antidepressant effect in most trials. This drug is a reminder of that, it was initially developed as an antidepressant before those failed trials and its subsequent resurrection as an anti-obesity drug. It was removed from the market for reasons that were probably somewhat spurious.. Another example is duloxetine which was developed around the same time, failed as an antidepressant, was shelved, was resurrected as incontinence prevention drug, and then eventually recycled successfully as an antidepressant!. Milnacipran was developed by a small French company (in the 1980s I think) and never gained acceptance as an effective antidepressant anywhere else, I do not know what trials were done unsuccessfully, one never does, and it was only after a company takeover that the levo-isomer was successfully marketed in the USA in 2013 as Fetzima. I do not know what kind of strange image ...

By Melania Zaharopoulos. The prescription drug market is awash in medications marketed for the treatment of depression with what could be as many as 30 common prescriptions on the market today, said Dr. Shan Crockett, a Santa Cruz psychiatrist who assists with a Hollister-based geriatric mental health program two days per week.. And while a wide variety of options are available, selecting the right prescription for each patient is a balancing act that takes into account symptoms, state of mind and family history before signing off a prescription.. œSome depressions are really agitated and some are really slow,? said Crockett. œWe would think about that, about whether there was a sleep problem involved or whether there were other things going on.. œWhen folks are very depressed, they still want to have sex. They come in and say, ˜Is this going to affect my drive?™ The other thing is ease of administration. Is it once a day? Three times a day? Do you go up in dosage once or is it a long ...

After the risk disclosure and boxed warning by the FDA were released in 2003 and 2004, there was substantial media coverage on the dangers of antidepressants in youth and anecdotal cases of antidepressant-related suicides in children.9 Several studies found major reductions in the diagnosis of depression and prescription of antidepressants to children, adolescents, and adults.11-14 Libby et al14 reported that, among primary care providers, there was a 44% decrease in the diagnosis rate of depression in children and adolescents younger than 18 years, a 37% decrease in young adults, and a 29% decrease in adults after the boxed warning was released. Prescription of antidepressants decreased, while the use of treatment alternatives such as anxiolytics, atypical antipsychotics, and child psychotherapy did not change considerably. According to Gibbons et al,15 rates of antidepressant prescriptions for children decreased by 20% after the warnings were released in 2003 and 2004. These findings ...

Major depressive disorder (MDD) is a chronic condition that affects one in six adults in the US during their lifetime. The current practice of antidepressant medication prescription is a trial-and-error process. Additionally, over a third of patients with MDD fail to respond to two or more antidepressant treatments. There are no valid clinical markers to personalize currently available antidepressant medications, all of which have similar mechanisms targeting monoamine neurotransmission. The goal of this review is to summarize the recent findings of immune dysfunction in patients with MDD, the utility of inflammatory markers to personalize treatment selection, and the potential of targeting inflammation to develop novel antidepressant treatments ...

Background Antidepressant medication is commonly used to treat depression. However, many patients do not respond to the first medication prescribed and improvements in symptoms are generally only detectable by clinicians 4-6 weeks after the medication has been initiated. As a result, there is often a long delay between the decision to initiate an antidepressant medication and the identification of an effective treatment regimen. Previous work has demonstrated that antidepressant medications alter subtle measures of affective cognition in depressed patients, such as the appraisal of facial expression. Furthermore, these cognitive effects of antidepressants are apparent early in the course of treatment and can also predict later clinical response. This trial will assess whether an electronic test of affective cognition and symptoms (the Predicting Response to Depression Treatment Test; PReDicT Test) can be used to guide antidepressant treatment in depressed patients and, therefore, hasten ...

Autism and the number of women taking antidepressant during pregnancy have increased. Is there a link between autism and maternal antidepressant use?

Not sure if this is the right place but I figured people might be interested in possible theories as to what causes MND. Looking back I took antihistamines almost every day for 16 years and was on many different antidepressants over the years and now Im sure all that affected my brain. I was getting brain zaps for many years even when I hadnt had any SSRI meds for years. The zaps were awful and sounded like neurons firing and drs couldnt explain it. Had MRI in 2017 and they couldnt find a cause. Since my motor related symptoms reared their ugly head I havent had the zaps. Did I cause this with all the medications? Im sure one day they will find out that taking a lot of antihistamines and antidepressants can cause it. Its devastating enough without thinking I might have done it to myself ...

Common antidepressants are medications that help people to cope with depressive states. They appeared in late 50s of the last century and up to date remain the main remedy to fight depression.. In addition to treatment of depression, common antidepressants can be used for the treatment of other mental disorders. For instance, anxiety disorder, posttraumatic stress disorder, agoraphobia and social phobia.. Today, people can buy common antidepressants without prescription at any pharmacy. These drugs help to eliminate the anxiety, depression and normalize sleep. Such medical agents affect the serotonin and norepinephrine metabolism in the brain and stimulate the human psyche.. Lately, depression has become a common disorder among teenagers. The cases of mild depression in teens are cured with herbal antidepressants. Effective herbal common antidepressants for teenagers are widely available in large quantities at pharmacies.. Such drugs can effectively cope with anxious and depressive states, ...

Individuals with late-life depression (LLD) experience high levels of disability, mortality, and poor responses to antidepressants. The MRI hallmark of vascular depression in this population is significant ischemic white matter lesion (WML) severity, a finding associated with poor antidepressant outcomes. Despite observations of diffuse white matter disease in LLD, we propose in our disconnection hypothesis that focal damage to fiber tracts negatively affects the function of connected regions, resultantly contributing to cognitive deficits and clinical symptoms such as depression severity and negativity bias. Focal WMLs may also reduce the likelihood of an antidepressant response when the specific antidepressant used acts on neurotransmitter systems projecting through the damaged fiber tract. This implies that the effect of tract damage on clinical response may differ between drugs with different mechanism of action.. We propose that the cingulum bundle (CB) and uncinate fasciculus (UF) are ...

Taking antidepressants may raise the risk of heart disease in men by producing a thickening of artery walls, researchers said Saturday. Although a potential mechanism for the action is not obvious,

This succulent herb from South Africa was once used as a bartering currency, according to written records that date back to the 1600s. Since then it has made its way to North America and has been embraced for its reported antidepressant properties, including its ability to help elevate mood and promote relaxation and a sense of well being.. Sceletium contains alkaloids that interact with receptors in the brain, affecting the release of dopamine (a compound that affects pleasure) and serotonin (a compound that affects mood). After you take it, you will feel its effects in about half an hour, and it feels great, says Chris Kilham, a researcher and author also known as the Medicine Hunter. The herb produces an increased sense of clarity and an enhanced capacity for ideas and mental focus, he says. Sceletium may also be useful in decreasing anxiety, stress and tension.. The alkaloids in sceletium act much like the pharmaceutical antidepressants known as selective serotonin reuptake inhibitors ...

Depression is common in women of childbearing age, and in Europe 3-8% of pregnant women are prescribed antidepressants during pregnancy.1 The fetal safety of antidepressant exposure during pregnancy has generated much debate after recent concerns of a possible association with autism in exposed offspring. In the past five years, several epidemiological studies2 3 4 5 6 7 8 9 10 11 have assessed the relation between antidepressant use during pregnancy and autism in offspring, but robust conclusions have been elusive.12 13 Although most studies found evidence of unadjusted associations, conclusions differed because of concerns about confounding by indication. This was because depression or other psychiatric indications for antidepressant use could be associated with autism through genetic or non-genetic pathways, and thus the possibility of the observed associations representing the risk of autism from the underlying indication for prescription could not be ruled out.. All antidepressants cross ...

SSRIs are not as effective for pain relief as SNRIs.. Even though the antidepressants may help diminish pain, their side effects can be unacceptable. A recent review found that although approximately 1/3 of patients who took antidepressants for neuropathic pain experienced moderate pain relief or better, 1/5 discontinued use due to adverse side effects.[1]. Common side effects of antidepressants are nausea, dizziness, insomnia, weight gain/loss, dry mouth and diminished interest in sex (decreased libido). If youre not having reasonable pain relief with one of these medications, it should not be continued.. ...

Depression, or more accurately, un-repaired emotional short-circuiting, can absolutely devastate your health and life. However, using antidepressants as the primary (or only) treatment option is simply not advisable, especially if the one suffering from depression is a child or teenager. Whereas severe depression can indeed progress to suicide if left untreated, antidepressant drugs have been shown to CAUSE both suicidal and homicidal thoughts and behaviors. As mentioned in the featured report, at least 11 tragic school shootings were done by children who were either on antidepressants, or going through withdrawal…. I believe this is an enormous price to pay for what amounts to highly questionable benefits.. Studies have found that up to 75 percent of the benefits of antidepressants could be duplicated by a placebo. So not only do these drugs not work as advertised, but the evidence is quite clear that most of these drugs do in fact increase your risk of suicide and violence. Since depression ...
