Sex influences in neurological disorders: case studies and perspectives.

TLDR: Case studies of neurological disorders affecting men and women, including multiple sclerosis and migraine, show strong sex differences in incidence and disease manifestation, to demonstrate the need for more such studies.

Abstract: Beginning in the late 1980s and early 1990s, scientists and the public alike recognized that, for too long, women had been underrepresented in clinical trials. While much progress was made in the following decades, preclinical research still often ignores sex as a fundamental biological variable. Many neurological disorders, including multiple sclerosis and migraine, show strong sex differences in incidence and disease manifestation. In this commentary, we highlight case studies of neurological disorders affecting men and women to demonstrate the need for more such studies. Research conducted in these areas so far has shed light on the underlying mechanisms of the disease and offers the promise to help develop more personalized treatments for both men and women.
