Genetic testing can detect if you are a carrier of the gene for this disorder. If you or your partner is from an at-risk population, you may wish to seek genetic counseling before starting a family. If you are already pregnant, testing the amniotic fluid can diagnose Tay-Sachs disease in the womb. Kwon JM. Neurodegenerative disorders of childhood.

The condition is usually fatal by around 3 to 5 years of age, often due to complications of a lung infection pneumonia. Rarer types of Tay-Sachs disease start later in childhood juvenile Tay-Sachs disease or early adulthood late-onset Tay-Sachs disease. The late-onset type doesn't always shorten life expectancy. Tay-Sachs disease is caused by a problem in a child's genes that means their nerves stop working properly. A child can only have it if both parents have this faulty gene.
The parents themselves don't usually have any symptoms — this is known as being a "carrier".

If you're pregnant or planning a pregnancy, you may be referred to a genetic counsellor to discuss having a test to see if you're at risk of having a child with Tay-Sachs disease and talk about your options. There's currently no cure for Tay-Sachs disease. The aim of treatment is to make living with it as comfortable as possible.
Your care team will talk to you about end of life issues, such as where you'd like your child to receive care and if you'd like them to be resuscitated if their lungs stop working.
