In this video, Fred (Michael) M. Cutrer, M.D., a neurologist at Mayo Clinic and co-author of the case study, discusses the treatment of the patient. He also discusses the nature of low CSF pressure headaches and how the case report gives physicians new insight into Botox and headache treatment. A Mayo Clinic case study finds Botox may offer new hope to people with disabling low cerebrospinal fluid (CSF) headaches.
