New research has found that coffee consumers had a lower risk of developing Parkinson’s disease compared to individuals not drinking coffee. Adjusting for smoking and alcohol consumption did not change these findings. The research was published in Neurology. Parkinson’s disease is a progressive neurodegenerative disorder that primarily affects movement control. It occurs due to the loss of dopamine-producing neurons in a specific area of the brain called the substantia nigra. Common symptoms include tremors, stiffness, slowed movement, and balance problems, which gradually worsen over time. In...

Parkinson’s disease is a neurodegenerative movement disorder that progresses relentlessly00218-X). It gradually impairs a person’s ability to function until they ultimately become immobile and often develop dementia. In the U.S. alone, over a million people are afflicted with Parkinson’s, and new cases and overall numbers are steadily increasing. There is currently no treatment to slow or halt Parkinson’s disease. Available drugs don’t slow disease progression and can treat only certain symptoms. Medications that work early in the disease, however, such as Levodopa, generally become ineffectiv...

Scientists have made a significant leap in understanding how our brains process social interactions, specifically focusing on the roles of dopamine and serotonin, two critical chemical messengers in the brain. The study, led by Virginia Tech neuroscientists and published in Nature Human Behavior, involved Parkinson’s disease patients who were undergoing brain surgery while awake. These patients participated in a game that tested their responses to financial offers from both humans and computers, revealing fascinating insights into the neurochemical underpinnings of social decision-making. Back...
