Underlying conditions discussion: There are over 60 different causes of the dementia syndrome, with Alzheimer's disease being the most common. 1

Dementia is a syndrome with over 60 causes. There are a number of causes with a direct genetic basis. For example, Huntington's disease, early onset familial Alzheimer's disease, trisomy 21 (Down syndrome), acute intermittent porphyris (a disorder which causes neurological symptoms), Wilson's disease (a hereditary disorder in which copper accumulates in tissues), mitochondrial encephalopathies, and several other causes of the dementia syndrome have a definite genetic origin.1

Dementia is caused by many conditions. Some conditions that cause dementia can be reversed, and others cannot. Further, many different medical conditions may cause symptoms that seem like Alzheimer's disease, but are not. Some of these medical conditions may be treatable. Reversible conditions can be caused by a high fever, dehydration, vitamin deficiency and poor nutrition, bad reactions to medicines, problems with the thyroid gland, or a minor head injury. Medical conditions like these can be serious and should be treated by a doctor as soon as possible. 2
