[Rehabilitation in Tay-Sachs disease: A case report]

Tay-Sachs disease, or GM2 gangliosidosis, is a congenital and neurodegenerative disease caused by the absence or deficiency of the essential enzyme B-hexosaminidase. The timing of the development of neurological manifestations and their severity depend on the mutation, time since disease onset and the patient's characteristics. The disease impairs quality of life and increases mortality. In the most aggressive forms, life expectancy is 3 years. Despite various clinical trials and ongoing research, there is currently no cure for Tay-Sachs disease. Treatment focuses on symptom control and ensuring greater patient wellbeing. Consequently, rehabilitation plays a fundamental role in the management of these patients and in enhancing their quality of life.
