Parkinsonism following bilateral chronic subdural hematoma that presented as orthostatic headache: Highlighting clinical pearls for family physicians and physiotherapists.

Abstract

Chronic subdural hematoma (CSDH) is a great mimicker. It should be considered in anyone presenting with chronic headaches that show postural variation. Parkinsonism following CSDH, while known, is only rarely reported in the literature. Hyponatremia, rapid correction of hyponatremia, medications, and mechanical pressure are thought to be risk factors. Here, we report a case of a 61-year-old male diagnosed with bilateral CSDH managed by craniotomy and clot evacuation who developed parkinsonism. We share several learnings (clinical pearls) that emerged from the close collaboration and co-learning curve between a family physician and physiotherapist involved in home-based rehabilitation. In conclusion, while managing the postoperative course of patients with CSDH, clinicians should maintain a high index of suspicion for parkinsonism. Early recognition and appropriate management with syndopa with supportive physiotherapy results in significant improvement of function and quality of life. Notably, parkinsonism following SDH is transient and nonprogressive and may not require lifelong therapy.
