Tay-Sachs disease is a genetic disorder in which fat deposits build up in nerve cells of the brain, leading to a slow loss of function. Because this disease usually strikes children under 1 year of age, the symptoms are not immediately apparent
Think about the symptoms that this condition would cause. List some that you think are possible. What would be the inevitable end result as the disease progresses?
The disease would interfere with neuron function in the brain. Because very young children don't speak, verbal communication is not a reliable measure of the illness. The most noticeable symptoms would be loss of motor function, difficulty swallowing, or inability to see or move around in response to stimuli. Eventually, motor function will be impaired to the point that the child will be unable to breathe. In the end, the disease is fatal.
