Overview
Sandhoff disease, adult form, is a rare inherited metabolic condition that belongs to a group of disorders called GM2 gangliosidoses. It is also sometimes called adult-onset Sandhoff disease or late-onset Sandhoff disease. In this condition, the body lacks enough of an enzyme called beta-hexosaminidase, which is needed to break down certain fatty substances (called gangliosides and other lipids) in nerve cells. When these substances build up, they gradually damage the nervous system. Unlike the more severe infantile form of Sandhoff disease, the adult form begins later in life and tends to progress more slowly. Symptoms usually involve the nervous system and can include muscle weakness, problems with balance and coordination, difficulty speaking, and sometimes psychiatric symptoms such as mood changes or psychosis. Some people also experience tremors or muscle cramps. The severity and speed of progression can vary widely from person to person. There is currently no cure for adult-onset Sandhoff disease. Treatment focuses on managing symptoms and maintaining quality of life. Physical therapy, occupational therapy, speech therapy, and psychiatric support may all play a role. Research into potential therapies, including gene therapy and substrate reduction therapy, is ongoing but no disease-modifying treatments are yet approved specifically for this condition.
