- PET imaging confirms direct involvement of dopamine in cognitive flexibilityon March 28, 2025 at 3:25 pm
Scientists have confirmed a neurobiochemical link between dopamine and cognitive flexibility. PET imaging shows that the brain increases dopamine production when completing cognitively demanding tasks, and that the more dopamine released, the more efficiently the tasks are completed. Armed with this information, physicians may soon be able to develop more precise treatment strategies for neurological and psychiatric disorders.
- AI technology improves Parkinson's diagnoseson March 19, 2025 at 6:34 pm
AI-driven software is 96% accurate at diagnosing Parkinson's.
- Scientists solve decades-long Parkinson's mysteryon March 13, 2025 at 7:18 pm
Researchers have made a huge leap forward in the fight against Parkinson's disease, solving a decades-long mystery. In a major breakthrough, they have been able to see the human PINK1 protein and how it is switched on for the first time. The discovery is a significant milestone in Parkinson's research that paves the way for developing new life-changing drugs.
- Blood test shows promise for early detection of dementiaon March 11, 2025 at 4:15 pm
For people with a certain sleep disorder, a simple blood test could help predict the development of dementia years before symptoms appear, a new study indicates. Idiopathic REM sleep behavior disorder (iRBD) causes people to physically act out their dreams while sleeping. The disorder is also associated with a very high risk of Parkinson's disease and a related condition called Dementia with Lewy Bodies. This is a form of dementia that often causes memory and cognitive loss, as well as vivid visual hallucinations and movement difficulties similar to Parkinson's.
- Clinical trial tests novel stem-cell treatment for Parkinson's diseaseon March 10, 2025 at 12:31 am
A recently launched Phase 1 clinical trial is examining the safety and feasibility of a groundbreaking treatment approach for Parkinson's disease in which a patient's stem cells are reprogrammed to replace dopamine cells in the brain. The clinical trial, based on more than three decades of research, has treated three-of-six participants who will be tracked for more than a year.
