Tay-Sachs Disease or TSD is a rare congenital disorder that if present typically affects the nervous system of infants aged 3-6 months.
TSD is caused by the absence of an enzyme (B-Hexosaminidase A) that breaks down fatty substances (GM2 ganglioside), resulting in progressive degradation of cells in the brain and spinal cord. Sadly the life expectancy of children with TSD is commonly 5 years.
There are a number of motor-neurological symptoms to be aware of, and medical advice should be sought if any such symptoms are present.
This web site is an general information site only and nothing here should be taken as advice. If you are concerned about someone you know developing TSD or wish to investigate TSD further, please seek medical advice from a specialist.
