Krabbe disease
Krabbe disease (also known as globoid cell leukodystrophy or galactosylceramide lipidosis) is a rare, often fatal degenerative disorder that affects the myelin sheath of the nervous system. It is a form of sphingolipidosis, as it involves dysfunctional metabolism of sphingolipids. This condition is inherited in an autosomal recessive pattern. The disease is named after the Danish neurologist Knud Haraldsen Krabbe (1885-1965).
Illinois, Kentucky,〔(KRS 214.155)〕 and Pennsylvania have laws to test for Krabbe and other diseases at birth. There is a movement in Maine and other states to adopt such regulations.
==Signs and symptoms==
Infants with Krabbe disease are normal at birth. Symptoms begin between the ages of 3 and 6 months with irritability, fevers, limb stiffness, seizures, feeding difficulties, vomiting, and slowing of mental and motor development. In the first stages of the disease, doctors often mistake the symptoms for those of cerebral palsy. Other symptoms include muscle weakness, spasticity, deafness, optic atrophy, optic nerve enlargement, blindness, paralysis, and difficulty when swallowing. Prolonged weight loss may also occur. Juvenile- and adult-onset cases of Krabbe disease also occur, which have similar symptoms but slower progression.
