One thousand and 679 Alzheimer's Disease patients (early onset EO: 152 and late onset LO: 1527) were evaluated after 12, 36 and 60 months. At baseline EO patients have higher Mini Mental State examination (MMSE) and fewer comorbidities in respect to LO group. The MMSE score did not significantly differ after 12, 36 and 60 months; a more marked worsening in instrumental daily activities was observed after 36 months in the EO compared with the LO group. These data allow to conclude that EO patients may have a slight faster progression in the disease within the first 3 years after the diagnosis, but in a longer follow-up no differences exist in respect to LO group. The literature failed to identify specific factors capable to influence the disease progression in AD. Our data are in substantial agreement with the literature and seem to confirm the great heterogeneity of AD patients.

D000544	Alzheimer Disease	A degenerative disease of the BRAIN characterized by the insidious onset of DEMENTIA. Impairment of MEMORY, judgment, attention span, and problem solving skills are followed by severe APRAXIAS and a global loss of cognitive abilities. The condition primarily occurs after age 60, and is marked pathologically by severe cortical atrophy and the triad of SENILE PLAQUES; NEUROFIBRILLARY TANGLES; and NEUROPIL THREADS.
