    What is (are) Schindler disease ?
    ### Response:
    Schindler disease is an inherited disorder that primarily causes neurological problems.  There are three types of Schindler disease. Schindler disease type I, also called the infantile type, is the most severe form. Babies with Schindler disease type I appear healthy at birth, but by the age of 8 to 15 months they stop developing new skills and begin losing skills they had already acquired (developmental regression).
