Maternal depression and a common class of antidepressants can alter a crucial period of language development in babies, according to a new study by researchers at the University of British Columbia, Harvard University and the Child & Family Research Institute (CFRI) at BC Children’s Hospital.

Published today in the Proceedings of the National Academy of Sciences, the study finds that treatment of maternal depression with serotonin reuptake inhibitors(SRIs) can accelerate babies’ ability to attune to the sounds and sights of their native language, while untreated maternal depression can prolong the period of tuning.

Researchers link genetic mutation to psychiatric disease and obesity

McGill researchers have identified a small region in the genome that conclusively plays a role in the development of psychiatric disease and obesity. The key lies in the genomic deletion of brain-derived neurotrophic factor, or BDNF, a nervous system growth factor that plays a critical role in brain development.

To determine the role of BDNF in humans, Carl Ernst, PhD, from McGill’s Department of Psychiatry, Faculty of Medicine, screened over 35,000 people referred for genetic screening at clinics and over 30,000 control subjects in Canada, the U.S., and Europe. Continue reading

May 24, 2012 -Fat Bastard’s revelation “I eat because I’m depressed and I’m depressed because I eat” in the Austin Powers film series may be explained by sophisticated neuroscience research being undertaken by scientists affiliated with the University of Montreal Hospital Research Centre (CRCHUM) and the university’s Faculty of Medicine.

Potential harm, but no demonstrated benefit from depression screening in primary care

Brett Thombs

September 19, 2011 – The Canadian Task Force on Preventive Health Care recommends routine screening for depression during primary care visits when systems are available for coordination of assessment and treatment. An article by an international panel of experts, published in the October issue of the Canadian Medical Association Journal, argues that there is no evidence that screening benefits patients and that, moreover, implementation of the practice would further burden an already financially-strapped health care system.

Study exposes major flaws in research on depression screening questionnaires – Research on detection of depression “forecasting yesterday’s weather,” say investigators

Par Hendrike 11:08, 3 May 2006 (UTC) (Travail personnel) [GFDL (www.gnu.org/copyleft/fdl.html) ou CC-BY-SA-3.0 (www.creativecommons.org/licenses/by-sa/3.0/)], via Wikimedia CommonsAugust 16, 2011 – A new analysis, published in the British Medical Journal (BMJ), reports that flawed research studies have exaggerated the degree to which depression screening questionnaires are able to accurately detect people with untreated depression. The number of untreated patients who would actually be detected using these questionnaires may be less than half the number predicted by existing studies. Continue reading

Children of depressed mothers have a different brain – MRI scans show their children have an enlarged amygdala

Amygdalae - there are two in your brain

August 15, 2011 – Researchers think that brains are sensitive to the quality of child care, according to a study that was directed by Dr. Sonia Lupien and her colleagues from the University of Montreal published today in the Proceedings of the National Academy of Sciences. Continue reading
