People diagnosed with Alzheimer's or mild cognitive impairment had weaker gamma wave activation in their brains than their peers without the neurodegenerative disorders.
A rare genetic mutation interferes with dopamine transporters in the brain, causing Parkinson's-like symptoms in children.
A new mathematical model delves into the biological changes that occur in both the aging brain and brains with neurodegenerative disorders. The implications lay forth a new path into developing therapies for neurodegenerative disorders that affect cognition.
