Tay-Sachs disease is a rare, inherited disorder that progressively destroys nerve cells in the brain and spinal cord. It occurs when the body is unable to break down certain fatty substances. Infants with Tay-Sachs develop normally for the first few months of life, but by the age of six months, they begin to lose motor skills and mental abilities. They may also become deaf and blind.
