Tay-Sachs is a disease of the central nervous system. It is a neurodegenerative disorder that most commonly affects infants. In infants, it is a progressive disease that is unfortunately always fatal. Tay-Sachs can also occur in teens and adults, causing less severe symptoms, although this occurs more rarely. Most affected infants have nerve damage starting in utero before birthwith symptoms appearing from age 3 to 6 months, in most cases.
Progression is rapid, and the child will typically pass away by 4 or 5 years old. If your child has a seizure or has trouble breathing, go to the emergency room or call immediately. There are also late-onset juvenile, chronic, and adult forms of the disease, which are much more rare, but tend to be milder in severity. People with the juvenile form of Tay-Sachs typically display symptoms between the ages of 2 and 10 and usually pass away by age Those with the chronic form of Tay-Sachs develop symptoms by the age of 10, but the disease progresses slowly.
Symptoms may include slurred speech, muscle cramps, and tremors. Life expectancy varies with this form of the disease, and some people have a normal lifespan.
Adult Tay-Sachs is the mildest form. Symptoms appear during adolescence or adulthood. People with the adult form of Tay-Sachs disease usually have these symptoms:. This defective gene causes the body to not make a protein called hexosaminidase A.
Without this protein, chemicals called gangliosides build up in nerve cells in the brain, destroying brain cells. The disease is hereditary, which means it is passed down through families.
