Decreased Gene Activity in Childhood Risk for Anxiety and Depression
Decreased activity of specific genes within the amygdala, the brain's fear center, may explain why in young children the "fear center" of the anxious brain can't learn to distinguish real threats from the imaginary, according to a new study.

Genetic Mutation Linked to Psychiatric Disease and Obesity
Researchers have identified a small region in the genome that conclusively plays a role in the development of psychiatric disease and obesity: The genomic deletion of brain-derived neurotrophic factor (BDNF), which is a nervous system growth factor that plays a critical role in brain development. Five individuals with BDNF deletions were obese and had a mild- to-moderate intellectual impairment and had a mood disorder.

Ketamine Conquers Chronic Depression
Many chronically depressed and treatment-resistant patients experience immediate relief from symptoms after taking small amounts of the drug ketamine. The drug triggers release of neurotransmitter glutamate, which in turn stimulates growth of synapses between brain cells damaged by stress and depression. (Science, 2012; 338 (6103): 68) Read more.
Stress Hormones Lower PTSD Risk
Increasing the presence of glucocorticoids may decrease the development of posttraumatic stress disorder (PTSD). A new study of drugs that restrict glucocorticoid activity suggests that high glucocorticoid levels may prevent the occurrence of PTSD. High levels of glucocorticoids during episodes of grave stress prevent anxiety-like behaviors by regulating synaptic connectivity in the basolateral amydgala area of the brain. (Biological Psychiatry, September 2012; published online) Read more.
Genetic Switch Involved in Depression
A new postmortem study, focused specifically on genes related to synapses, reveals that about 30 percent of the genes with significantly lower expression in people with depressed brains related to some aspect of synapse function. Further experiments found significantly reduced expression for five particular genes in the prefrontal cortex of depressed people. (Nature Medicine, 2012(18):1413–1417) Read more.
Prejudice Can Cause Depression
Research suggests that many cases of depression may be caused by prejudice from the self or from another person. The researchers propose an integrated perspective of prejudice and depression, which holds that stereotypes are activated in a person who expresses prejudice toward another and causes that person to become depressed.

GAD and Reduced Brain Connections Revealed
A new imaging study shows that the amygdala in people with generalized anxiety disorder (GAD) appears to have weaker connections to the prefrontal and anterior cingulate cortex (ACC), the center of emotional regulation, suggesting that the brain’s "panic button" may stay on due to lack of regulation. (Archives of General Psychiatry, 2012;69(9):925-934) Read more.
Expressing Emotions Can Reduce Fear
A new study suggests that labeling emotions at the precise moment of confronting a feared object can reduce fear and anxiety.

Lack of Correlation of Fear Extinction With Personality and Neuropsychological Indices
Fear extinction may be less determined by trait variables and cognitive state, and may depend more on a person’s current emotional state. The negative correlation between fear renewal and extraversion suggests that this personality characteristic may protect against post-treatment relapse of symptoms of anxiety disorders.

Genetic Clues to OCD and Tourette Syndrome
The first genome-wide studies looking at the potential association of particular genes with obsessive-compulsive disorder (OCD) and Tourette syndrome contributed important new clues.
