Noun: A rare, inherited, and fatal disorder that destroys nerve cells in the brain and spinal cord. It is caused by the absence of a vital enzyme, leading to the harmful accumulation of fatty substances (lipids) in nerve tissue. The disease is most commonly associated with individuals of Ashkenazi Jewish descent.
