A genetic risk factor for substance abuse

A functional polymorphism within the m-opioid receptor gene has been linked to an increased risk of substance abuse, including alcohol and other substances. The study found that individuals with this genetic variation were more likely to develop addiction and engage in risky behavior.

A genetic basis for diet-induced relapse of depression

A genetic study found that a polymorphism in the serotonin transporter promoter region is associated with mood response during tryptophan depletion, indicating a potential link between diet and depression relapse. The study suggests that individual genetic differences may influence the impact of dietary changes on depressive symptoms.

Magnetic stimulation may be as effective as electroconvulsive therapy in treating severe depression

A University of Illinois study suggests that repetitive transcranial magnetic stimulation (rTMS) is a promising alternative to electroconvulsive therapy (ECT) for treating severe depression, with better tolerability and fewer side effects. rTMS showed significant improvement in depression scores, with a 55% reduction in the treatment g...

The power of positive thinking

A systematic review of literature found an association between positive expectations and improved outcomes in myocardial infarction, cardiac surgery, chronic pain, and psychiatric conditions. The mechanisms behind this association are still uncertain, with questions surrounding causality versus prediction.

Tackling seasonal depression in Canada

A new national study in Canada aims to test different types and combinations of anti-depressants and fluorescent light therapy for patients with seasonal depression. Researchers hope to better understand this debilitating condition that affects over 600,000 Canadians each year, causing significant dysfunction and impairment.

New genes and old genes contribute to personality traits

Researchers found associations between certain personality traits and a polymorphic region in the human AP-2beta gene. These traits include muscular tension, guilt, somatic anxiety, psychasthenia, and indirect aggression. The study suggests a novel approach to understanding the genetic basis of psychiatric disorders and personality.

A Genetic Marker Of Panic Disorder

Researchers identify a genetic marker associated with panic disorder, linked to variations in cholecystokinin (CCK) receptor function. The study found that this variation could be a risk factor for panic attacks and may be useful in diagnosis and therapeutic approaches.

Psychiatrists Strongly Oppose Assisted Death

A survey of consultation-liaison psychiatrists found that they strongly opposed participating in or endorsing physician-assisted death. However, there was more acceptance of referrals to other physicians and their involvement. The study suggests that requests for assisted death are often linked to depression, a treatable illness.

Is There Really A Gene For Personality?

A study of Finnish subjects failed to find an association between the Dopamine D4 Receptor (DRD4) gene and novelty-seeking personality traits. The researchers found that individuals with higher novelty-seeking scores had a lower frequency of the DRD4 gene, contradicting previous findings.
