Biography
Bousser graduated from Paris-Sorbonne University in neuro-psychiatry in 1972 with her thesis devoted to the prevention of cortical artery thrombosis in rabbits by aspirin and PGE1.

She trained at the Pitié-Salpêtrière Hospital. Subsequently, she worked at the National Hospital for Neurology and Neurosurgery, before returning to Paris.

She returned to Pitié-Salpêtrière Hospital in 1997, becoming the head of neurology there. She later became Emeritus Professor at the Paris-Diderot University.

Research
Bousser is most well known for her role in the discovery of CADASIL, a hereditary form of stroke. She researched the, then unnamed, condition for the first time in 1976, when a patient entered her clinic with signs of Binswanger's disease after suffering a stroke. She found that the condition was hereditary after children of the initial patient presented similar symptoms. In 1993 she showed, together with Elisabeth Tournier-Lasserve, that the condition was caused by a mutation on chromosome 19. They subsequently named the condition CADASIL.
