Additional treatment options

Neuroprotective Agent Trial

In cases where substantia nigra involvement suggests Parkinsonian features, neuroprotective agents such as coenzyme Q10 or other mitochondrial support supplements may be considered, though evidence remains evolving.

medication

Motor Function Rehabilitation

Comprehensive physical therapy program targeting balance, gait, and motor coordination if substantia nigra findings correlate with movement symptoms. Includes progressive exercise protocols.

Antioxidant Support Regimen

Dietary or supplemental antioxidants including vitamin E, alpha-lipoic acid, and omega-3 fatty acids may provide neuroprotective benefit in substantia nigra pathology, though clinical evidence remains preliminary.
