Abstract
The heterogeneity and variants of Alzheimer disease (AD) are reviewed. There are cases with a slow or fast evolution and with early or late onset. Most cases are sporadic but there are also hereditary forms. About 50% of patients show neuropsychiatric disorders (depression and psychoses). Some cases have a greater deficit of right or left hemispheric functions. Among the variants, there are forms that start as pure aphasias, predominantly prefrontal cases and posterior cortical forms. Occasionally AD may simulate other disorders such as supranuclear palsy, corticobasal ganglionar degeneration and Jacob-Creutzfeldt disease. Finally, there are mixed forms, in which AD is associated with cerebrovascular disease (very commonly) and with other diseases such as dementia with Lewy bodies. We conclude that AD is a heterogeneous disorder and, therefore, clinical diagnosis may be insufficient. Biological markers and specific imaging studies are needed for a correct clinical diagnosis
