Scientists have linked insulin resistance to an increased risk of developing major depressive disorder.

Few studies have explored the effect of psychological stressors on behavior, and neurogenesis, in the context of depression. With the elucidation of a vicarious social defeat stress mouse model, scientists have successfully endeavored in connecting the dots between psychological stress and depression.

Loneliness is a painful feeling. If it persists, it can lead to mental illnesses such as depression or anxiety disorders. Researchers have now discovered how loneliness is associated with reduced trust. This is reflected in changes in the activity and interaction of various brain structures, especially the insular cortex. The results therefore provide clues for therapeutic options.

Six stages of engagement in treatment of Attention-Deficit/Hyperactivity Disorder (ADHD) have been reported by researchers based on a diverse study, inclusive of parents of predominantly racial and ethnic minority children with ADHD.

Researchers find that youth who witness the abuse of a brother or sister by a parent can be just as traumatized as those witnessing violence by a parent against another parent. Such exposure is associated with mental health issues like depression, anxiety and anger.

A new study investigates subthreshold depression, a more severe form of depression that includes not only sad mood, but also some of the other symptoms of depression, and reports that psychological interventions may have a modest, but significant effect on the treatment of this type of depression in adolescents.

A large study has found a link between ADHD and dementia across generations. The study shows that parents and grandparents of individuals with ADHD were at higher risk of dementia than those with children and grandchildren without ADHD.

The key to overcoming addictions and psychiatric disorders lives deep inside the netherworld of our brains and the circuitry that causes us to feel good. Just like space, this region of the brain needs more exploration. Researchers have now pushed the science forward on our reward pathways and found there is another pathway beyond dopamine.

Depression is common in people with multiple sclerosis (MS), and a new study shows that people with both conditions may be more likely to die over the next decade than people with just one or neither condition. The study also found that people with MS and depression have an increased risk of developing vascular disease such as heart attack and stroke.

COVID-19 survivors report significantly higher symptoms of post-traumatic stress, and these symptoms are associated with changes to the brain's connectivity, according to a new study.
