Daytime Sleepiness Linked to Increased Alzheimer’s Risk
A new study reports daytime sleepiness may increase the risk of developing Alzheimer's disease. Researchers report those who are sleepy during the day are three times more likely to have amyloid beta deposits in their brains.... Read More...
Alzheimer’s May Soon Be Predicted During Eye Exams
According to researchers, it may soon be possible to diagnose Alzheimer's disease during a simple eye exam. The study reports those with elevated amyloid and tau levels have significant thinning at the center of the retina.... Read More...
Researchers Trace Parkinson’s Damage in the Heart
By the time typical symptoms of Parkinson's appear and patients are diagnosed with the disease, 60% of people experience significant damage to the heart's connections to the sympathetic nervous system. Researchers have investigated where inflammation and oxidative stress occur in the heart, and how this relates to heart problems associated with Parkinson's.... Read More...
Autism Linked to Cerebellum Shape
Researchers report boys on the autism spectrum tend to have lower fractal dimension in the right side of the cerebellum than those without autism.... Read More...
Stress Affects People with Schizophrenia Differently
A new study reveals people with schizophrenia have a disrupted stress response. Researchers report those with schizophrenia have an increase in dopamine release in the striatum, but not in the prefrontal cortex, in response to stress.... Read More...
Pathway for Alzheimer’s Degeneration Discovered
Researchers have developed a new neuroimaging method to track neurodegeneration in Alzheimer's disease. The method helped uncover a new pathway for how degeneration spreads from one brain region to another.... Read More...

Researchers have developed new neural implants that enable targeted delivery of drugs deep into brain structures.... Read More...
People with Family History of Alcoholism Release More Dopamine in Expectation of Alcohol
A new study reports people who have a family history of alcohol use disorder release more dopamine in the ventral striatum as a response to the expectation of receiving an alcoholic drink than those without a family history of alcoholism.... Read More...
Vascular Risk Interacts with Amyloid Levels to Increase Age Related Cognitive Decline
Vascular risk factors appear to have a negative synergistic effect with amyloid beta levels in the brain, researchers report. The study suggests a combination of increased vascular risk and higher amyloid levels in the brain can predict more rapid cognitive decline during aging.... Read More...
