Researchers identify protein that contributes to tau neurotoxicity in Alzheimer’s disease

Researchers have identified a protein that interacts and enhances the spread of neurotoxic species of tau — which is primarily found in neurons that appear abnormal in the brains of Alzheimer’s disease patients.

Mental health, substance use issues prevalent among nonpsychiatric emergency room patients

A new study found that about 45 percent of patients who visit the emergency department for physical injuries and ailments also have mental health and substance use problems that are often overlooked.

Study yields clues to why Alzheimer’s disease damages certain parts of the brain

A study yields clues to why certain parts of the brain are particularly vulnerable to Alzheimer’s damage. It comes down to the gene APOE, the greatest genetic risk factor for Alzheimer’s disease. The parts of the brain where APOE is most active are the…

Gossypetin found in hibiscus may beat Alzheimer’s disease

A research team has verified that gossypetin activates immune cells in the brain that clear A beta, which triggers Alzheimer’s disease.

Pattern of gene activity for ADHD

Researchers have successfully identified differences in gene activity in the brains of people with attention deficit hyperactivity disorder (ADHD). The study found that individuals diagnosed with ADHD had differences in genes that code for known chemic…

Corporal punishment affects brain activity, anxiety, and depression

Don’t spank your kids. That’s the conventional wisdom that has emerged from decades of research linking corporal punishment to a decline in adolescent health and negative effects on behavior, including an increased risk for anxiety and depression. Now,…

Alzheimer’s risk gene undermines insulation of brain’s ‘wiring’

In people carrying the APOE4 risk variant, a key brain cell type mismanages cholesterol needed to insulate neurons properly –another sign that APOE4 contributes to disease by disrupting lipids in the brain.

The hunt for disrupted brain signals behind autism

Part of understanding the underlying causes of autism spectrum disorder relies on figuring out which cells’ signaling patterns in the brain are disrupted, and when during nervous system development the disruption occurs. New research findings in mouse …

How hormonal birth control may affect the adolescent brain

One aspect of hormonal contraceptives’ effect on the teenage body remains a mystery — whether and how they modify the developing brain. New research in young rats links synthetic hormones found in birth control pills, patches and injections with disor…
