Prevalence and severity of dementia among northern Italian centenarians.
Using diagnostic criteria from the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders, dementia was clinically diagnosed in 57 (62%) of 92 centenarians living in two northern Italian provinces. The condition was severely disabling in approximately 70% of the demented patients. Although clinically diagnosed AD accounted for 79% of dementia cases, almost one third of patients with AD had risk factors for vascular dementia, suggesting that the aging brain may be susceptible to multiple additive factors that impair cognition.
