June 18, 2026 Scientists may have uncovered a hidden trigger behind Alzheimer’s disease. Instead of plaques being the root cause, amyloid beta appears to interfere with tau, a protein that helps keep neurons functioning properly. This disruption could set off ...
June 13, 2026 Scientists have uncovered a surprising new genetic cause of a rare movement disorder after analyzing nearly 3,000 patients with conditions affecting coordination and muscle control. The team identified mutations in a gene called CD99L2, previously ...
May 28, 2026 A newly identified protein called GPNMB may play a major role in helping Parkinson’s disease spread through the brain. Researchers discovered that immune cells release the protein in response to ...
May 27, 2026 Scientists in Japan have created powerful new vitamin K-based compounds that may help the brain regenerate lost neurons — a breakthrough that could one day change how diseases like Alzheimer’s and Parkinson’s are treated. By combining vitamin ...

July 17, 2026 A study of 225 newborns suggests prenatal estrogen may have played a role in the evolution of larger human brains. Boys with finger-length patterns linked to higher estrogen exposure before birth ...
May 16, 2026 Researchers have shown for the first time that malfunctioning mitochondria — the cell’s energy generators — may directly cause cognitive decline in neurodegenerative diseases. By creating a new ...
Mar. 16, 2026 A new UCLA Health study suggests that long-term exposure to the pesticide chlorpyrifos may dramatically raise the risk of Parkinson’s disease. Researchers found that people living in areas with ...
Feb. 20, 2026 A groundbreaking clinical trial is testing whether specially engineered stem cells can help the brain restore its own dopamine production in people with Parkinson’s disease. Because the condition ...
Feb. 10, 2026 Human evolution has long been tied to growing brain size, and new research suggests prenatal hormones may have played a surprising role. By studying the relative lengths of index and ring fingers — ...
Feb. 8, 2026 A new international study points to a specific brain network as the core driver of Parkinson’s disease. Scientists found that this network becomes overly connected, disrupting not just movement but ...
Feb. 6, 2026 Scientists at Keck Medicine of USC are testing an experimental stem cell therapy that aims to restore the brain’s ability to produce dopamine, the chemical whose loss drives Parkinson’s disease. ...
Feb. 6, 2026 New research using rhesus monkeys suggests that the brain’s relationship with alcohol may begin forming long before a person ever takes a drink. Scientists found that exposure to alcohol before ...
Jan. 29, 2026 Scientists in Sweden and Norway have uncovered a promising way to spot Parkinson’s disease years—possibly decades—before its most damaging symptoms appear. By detecting subtle biological ...
Jan. 28, 2026 A massive international study of more than 3,100 long COVID patients uncovered a striking divide in how brain-related symptoms are reported around the world. In the U.S., the vast majority of ...

Jan. 20, 2026 Researchers have identified a key molecular interaction that accelerates Parkinson’s disease by damaging the brain’s energy systems. They designed a new treatment that intercepts this harmful ...
Jan. 16, 2026 Researchers have identified OTULIN, an immune-regulating enzyme, as a key trigger of tau buildup in the brain. When OTULIN was disabled, tau vanished from neurons and brain cells remained healthy. ...
Dec. 22, 2025 A new study shows dopamine isn’t the brain’s movement “gas pedal” after all. Instead of setting speed or strength, it quietly enables movement in the background, much like oil in an engine. ...
