Antidepressant treatment may reduce male fertility

Treatment with paroxetine (Paxil), which belongs to the selective serotonin reuptake inhibitor (SSRI) class of antidepressant drugs, increases DNA fragmentation in sperm, according to research presented today at the sixty-fourth annual meeting of the American Society for Reproductive Medicine in San Francisco.
Although the study did not directly evaluate male fertility, the fivefold increase in the number of men who developed abnormal sperm DNA while being treated with paroxetine is "troubling" and "suggests an adverse effect on fertility," co-investigator Dr 
Depression and the Nobel Prize
sea-maid submitted, created time 4 weeks 22 hours (well.blogs.nytimes.com)
Anyone who has struggled with depression—either in themselves or a loved one—will be moved by the story of Douglas C. Prasher.
Dr. Prasher, who now drives a courtesy van for a car dealer, abandoned a life of scientific research years ago. Trained as a biochemist, Dr. Prasher has struggled over the years with bouts of depression.
His story wouldn’t be notable except for a startling fact: his early research led to a Nobel Prize-winning discovery about the inner workings of living cells. Dr

Since the time of ancient Egypt, societies have struggled to understand mental illness and to care for those affected by it. But, over the millennia, the idea that mental illness might have a biological cause arose only intermittently, and treatments ranged from the benign (exercise, humour and music) to the barbaric (exorcism, imprisonment and lobotomy). By the mid-twentieth century, however, several breakthroughs had been made
NIH Suspends Grant to Emory University

The National Institutes of Health (NIH) has suspended a $9 million grant for a depression study led by psychiatrist Charles Nemeroff at Emory University in Atlanta. The punishment, imposed in August but only made public today, is apparently the most severe reaction by NIH so far to a Senate investigation of NIH-funded researchers who may have failed to report all of their income from drug companies.
Recipients of NIH grants are required to report income from industry consulting activities

U.S. regulators have approved AstraZeneca's (AZN.L: Quote, Profile, Research, Stock Buzz) drug Seroquel XR as a treatment for bipolar disorder, extending the medicine's use beyond schizophrenia, the Anglo-Swedish company said ...
Repossession "is mental threat"
sea-maid submitted, created time 1 month 1 week (news.bbc.co.uk)
Sometimes depression and other mental problems are caused by an inherent imbalance in brain chemistry. We refer to this as clinicl depression. At other times, however, depression is caused by life events. A family member dies, and the patient becomes depressed. It is natural, understandable, and, depending on how the patient manages it, it can be healthy.
So what are the life events most likely to cause this natural depression? House repossession--foreclosure--was rated as one of the top causes, ahead of finding out about infertility
Physicians practicing assisted suicide are asked to better screen patients for depression

This article is particularly concerned with Oregon's Death with Dignity Act, which requires physicians who suspect that a patient requesting help in ending his or her live might be suffering from clinical depression to have said patient evaluated by a mental health professional. However, the proportion of such patients who actually are evaluated has dropped and continues to drop.
Last year, forty-six patients died by physician-assisted suicide in Oregon. None of them were evaluated to see if depression had affected their judgment.
C-sections might affect a new mother's ability to bond
Darkfrog submitted, created time 2 months 1 week (well.blogs.nytimes.com)
This is interesting. It's a New York Times writeup of a study in the Journal of Child Psychology and Psychiatry showing that women who deliver their children vaginally as opposed to by C-section are more responsive to the sound of infants crying a short time after the birth takes place.
There are some flaws in this study. First off, it only involved a small number of women, which increases the likelihood of statistical errors. Second, it does not show how whether this is a case of delayed attachment or stunted attachment. C-section moms might well catch up as time passes
Exposure to antipsychotics and risk of stroke
lavrock submitted, created time 2 months 3 weeks (www.bmj.com)
In UK primary care antipsychotic drug use was associated with an increased risk of stroke, and the risk was raised further by use of atypical drugs and by having dementia, according to this self controlled case series study. An accompaning editorial explains how this study design illustrates the relation between antipsychotics and stroke.
Gene mutations reveal schizophrenia's complexity
sea-maid submitted, created time 2 months 4 weeks (www.newscientist.com)
The three largest genetic schizophrenia studies to date have uncovered several ways in which changes to the genome may increase the risk of developing the condition.
The studies bring to light several common variations that increase the risk slightly, and rarer ones that raise it significantly, researchers say.
Early pregnancy trauma boosts schizophrenia risk

Excessive stress is never a good thing, but new research suggests that children of women who suffered severe psychological stress during early pregnancy are more likely to develop schizophrenia. ...
Missing DNA Boosts Risk of Schizophrenia
sea-maid submitted, created time 3 months 2 weeks (sciencenow.sciencemag.org)
Two large studies of schizophrenia patients have yielded the most convincing evidence yet that the disease can be caused by mistakes in genes. The researchers linked a much higher risk for schizophrenia to three chromosomal regions that are missing chunks of DNA. Although only a tiny fraction of patients carried these particular glitches, similar errors may help explain other cases of the disease.
Gene surveys identify schizophrenia triggers
sea-maid submitted, created time 3 months 2 weeks (www.nature.com)
Rare genetic changes associated with a heightened risk of schizophrenia have been revealed by two independent studies.
The surveys have identified sections of the human genome that, when deleted, can elevate the risk of developing schizophrenia by up to fifteen times compared with the general population.
Brain electrodes tackle severe depression

Severely depressed patients who do not respond to conventional therapy may be helped by deep brain stimulation (DBS), according to the most-extensive study to date of the experimental procedure
Obsessed Brains May Be Sluggish

The repetitive behavior of obsessive-compulsive disorder (OCD), such as excessive hand-washing or turning the lights on and off multiple times before leaving a room, sounds like the product of a mind in overdrive. But it may actually be the result of an underactive brain, according to a new study.
