- Three distinct brain circuits in the thalamus contribute to Parkinson's symptomson June 8, 2022 at 3:25 pm
Neuroscientists identified three circuits in the thalamus that influence the development of motor and nonmotor symptoms of Parkinson's disease. And by manipulating these circuits, they could reverse Parkinson's symptoms in mice.
- Bad dreams could be early warning of Parkinson's diseaseon June 7, 2022 at 11:44 pm
Older adults who start to experience bad dreams or nightmares could be exhibiting the earliest signs of Parkinson's disease, say researchers.
- 'Happy hormone' dopamine plays role in identifying emotionson May 24, 2022 at 3:06 pm
Emotion-recognition among people with disorders such as Parkinson's disease or schizophrenia may be affected by changes in the levels dopamine in the brain, say researchers.
- 'Sting' protein's efforts to clean up brain cell damage may speed Parkinson's disease progresson May 19, 2022 at 5:27 pm
In studies with mouse and human tissue, as well as live mice, researchers report that a snag in the normal process of cleaning up broken DNA in brain cells may hasten the progression of Parkinson's disease. Specifically, the researchers found that a protein dubbed 'STING' responds to clean-up signals in brain cells damaged by Parkinson's disease by creating a cycle of inflammation that may accelerate the disease's progression.
- Ultra-powerful brain scanners offer hope for treating cognitive symptoms in Parkinson's diseaseon May 17, 2022 at 1:31 am
Ultra-powerful 7T MRI scanners could be used to help identify those patients with Parkinson's disease and similar conditions most likely to benefit from new treatments for previously-untreatable symptoms, say scientists.
