Definition of Tay sachs
Tay-Sachs disease is a rare inherited disorder that progressively destroys nerve cells (neurons) in the brain and spinal cord. It is a potentially fatal disease of the nervous system.
Diagnosis
The doctor or nurse will examine the baby and ask questions about your family history. Tests that may be done are: Enzyme exam of blood or body tissue for hexosaminidase levels Eye exam (reveals a cherry-red spot in the macula)
Treatment
There is no treatment for Tay-Sachs disease itself, only ways to make the patient more comfortable.
Cause of Tay sachs
This disease is caused by an abnormal gene that causes the absence or low levels of an enzyme called hexosaminidase A (HEXA) that helps break down a fat called ganglioside GM2. This material builds up in the brain and cause damages nerve cells and cause neurological problems.
