Some disorders unique to children may also cause dementia. Niemann-Pick disease is a type of inherited disorder where specific gene mutations affect metabolism of cholesterol and lipids so excessive amount of cholesterol accumulates in liver and spleen while excessive lipids accumulate in brain. The symptoms include dementia, confusions and problems of learning and memory. The disease is known to affect the young school going children but may also affect teen agers.

Batten disease is also a fatal hereditary disorder of the central nervous system occurring in childhood. The symptoms include formation of lipopigments in body tissues and early symptoms include personality and behavior changes, clumsiness or stumbling. As the disease advances children may experience mental impairment, loss of sight and motor skills, become blind and bedridden. Lafora body disease is a rare genetic disorder responsible for causing progressive dementia and movement problems. The symptoms arise in the early childhood or late teens and are characterized by the presence of Lafora bodies in brain, skin, muscles and liver and death of child within 2-10 years.
