<unk>  <unk> , also known as Batten Disease) is the general name for a family of at least eight genetically separate neurodegenerative disorders that result from excessive accumlation of lipopigments (lipofuscin) in the body's tissues.  These lipopigments are made up of fats and proteins. Their name comes from the technical word lipo, which is short for "lipid" or fat, and from the term pigment, used because they take on a greenish-yellow color when viewed under an ultraviolet light microscope. The lipopigments build up in cells of the brain and the eye as well as in skin, muscle, and many other tissues.
