Right-handedness influences brain damage location in people with premotor Parkinson’s disease

Takeaway

  • In the premotor stages of Parkinson’s disease (PD), the neurodegenerative process may begin asymmetrically, initially impairing the nigrostriatal system of the dominant hemisphere.

Why this matters

    This study adds to our understanding of the neurodegenerative process in people with isolated rapid eye movement (REM) sleep behavior disorder (IRBD) who may develop PD.
