A study found that a significant proportion of Parkinson's disease diagnoses are later corrected. Up to one in six diagnoses changed after ten years of follow-up, and the majority of new diagnoses were made within two years of the original diagnosis.
Parkinson's doesn't just affect movement and the brain -- it may also impact the heart, according to new research. Scientists suggest that targeting a key protein outside of the brain could help manage Parkinson's-related heart issues.
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.
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.
