What is Maladie de Lewy?

The specific condition cited by her family is the maladie de Lewy (Lewy Body Dementia). This is a complex neurodegenerative disorder that shares symptoms with both Parkinson’s and Alzheimer’s diseases. It is characterized by abnormal protein deposits in the brain that disrupt mental and physical functions.  

The maladie de Lewy often causes fluctuations in alertness, visual hallucinations, and tremors. Tragically, it is the same condition that affected late actor Robin Williams. By being open about her diagnosis, Baye’s family has brought much-needed attention to this challenging disease, which affects nearly 250,000 people in France alone.
