Lipid Storage Diseases
Lipid storage diseases are a group of inherited metabolic disorders in which harmful amounts of fatty materials (lipids) accumulate in various tissues and cells in the body. Lipids are important parts of the membranes found within and between each cell and in the myelin sheath that coast and protects the nerves. Over time, this excessive storage of fats can cause permanent cellular and tissue damage, particularly in the brain, peripheral nervous system, liver, spleen, and bone marrow. Lipid storage diseases are inherited from one or both parents who carry a defective gene. Symptoms may appear early in life or develop in the teen or even adult years. Neurological complications of the lipid storage diseases may include ataxia, eye paralysis, brain degeneration, seizures, learning problems, spasticity, feeding and swallowing difficulties, slurred speech, loss of muscle tone, hypersensitivity to touch, pain in the arms and legs, and clouding of the cornea.
