Early Levodopa-Induced Motor Complications in RAB39B X-Linked Parkinsonism

While levodopa may benefit some patients with monogenic Parkinson's Disease and parkinsonism, others may exhibit aberrant responses earlier after exposure. Reporting treatment responses in rare genetic parkinsonism will help tailor therapeutic approaches to specific patients subpopulations.

We report the therapeutic response in a patient with RAB39B X-linked parkinsonism, who exhibited motor and non-motor complications within a few months of Levodopa.

Severe and debilitating Levodopa-induced complications can occur very early in the treatment course of X-linked parkinsonism, highlighting the need for an individualized therapeutic approach and follow-up in rare parkinsonian syndromes.
