Neurological Improvement with Medical Cannabis in a Progressive Supranuclear Palsy Patient: A Case Report

Progressive supranuclear palsy (PSP) is a severe, debilitating, and often fatal disease resembling other neurodegenerative disorders, namely Alzheimer's (AD) and Parkinson's (PD) diseases, which have been successfully treated with cannabinoids. We herein report the case of a 71-year-old woman diagnosed with PSP, displaying severe impairment of motor and language functions which progressively improved after treatment with medical cannabis. Before treatment, the patient was unable to move her limbs, was fed soft food, and was unable to speak or move her eyes. The patient has regained horizontal eye movement, is able to walk with assistance, has returned to physiotherapy, started to eat solid food, and has had a remarkable improvement in her speech. The possible mechanisms of this improvement are discussed.
