Researchers at the University of Birmingham have shown that reducing dopamine signaling in the brain can impair people’s ability to recognize emotions or understand others’ mental states (mentalizing), symptoms that may be experienced by those with Parkinson’s disease. The study, “Disruption of dopamine D2/D3 system function impairs the…

High-intensity exercise can boost dopamine signaling in the brain

Participating in high-intensity exercise can help protect the brain from progressive damage in Parkinson’s disease, a proof-of-concept imaging study suggests. “This is the first time imaging has been used to confirm that the biology of the brain in those suffering with Parkinson’s disease is changed by intense exercise,” Evan…
