A meta-analysis of 203 articles from 29 countries found that individuals with mental health disorders have a relative risk of mortality 2.22 times higher than the comparison population. The majority of deaths among people with mental health disorders are due to natural causes, with a median potential life lost of 10 years.
A major study by McGill University and the University of Edinburgh found that long-term smoking causes thinning of the brain's cortex, accelerating cognitive decline. Stopping smoking helps restore part of the cortex's thickness, but recovery is slow and incomplete.

Researchers analyzed brain scans of young adults at clinical high risk for psychosis and healthy controls, revealing a significant correlation between proinflammatory cytokines and gray matter thinning.
A long-term study of civilian women found that those with more PTSD symptoms had a nearly two-fold increased risk of developing type 2 diabetes. The study suggests that antidepressant use and higher body mass index associated with PTSD may mediate this relationship.
The study found that major depression was highly prevalent in adolescents, with a lifetime prevalence rate of 11%, and females had twice the rates of males. The majority of adolescents with MDD demonstrated severe role impairment and substantial comorbidity with other mental conditions.
Research reveals that women experience stronger urges to smoke at the beginning of their menstrual cycle due to hormonal changes. This knowledge could help women overcome abstinence-related withdrawal symptoms more easily, especially during the mid-luteal phase when estrogen and progesterone levels are higher.
A study published in JAMA Psychiatry found that children whose parents have attempted suicide are nearly 5 times more likely to attempt suicide themselves. Researchers followed the children of 701 parents with mood disorders for an average of six years, and found a direct effect of parental suicide attempt on child suicide attempt.
Researchers found that music playing alters motor areas of the brain, influencing executive functioning, working memory, and emotional processing. A child's musical background also correlates with cortical thickness in behavior-regulating areas.

The researchers are encouraged by the results and plan to replicate the study and test various concentrations of laughing gas.
A Penn Medicine study suggests that disruptions in brain memory-related activity after quitting can identify smokers at risk of relapsing. Smokers who failed to quit had decreased activity in the left dorsolateral prefrontal cortex and reduced suppression of activation in the posterior cingulate cortex, indicating a higher chance of re...
A new study published in Biological Psychiatry suggests that deficits in the brain's 'off switch' for anxiety, neuropeptide Y receptors, are associated with anxious temperament. Researchers found decreased expression of two neuropeptide Y receptors in the central nucleus of the amygdala, a region crucial for regulating fear and anxiety.
