Abstract

We have calculate the prevalence rates of moderate and severe dementia of the Alzheimer type (DAT) and of multi-infarct dementia (MID) in a Sicilian population sample aged 40 and over. For DAT the prevalence rate is 0.80% among the over 40s and 2.42% among the over 65s. The prevalence rates for both types, but especially for DAT, increase higher prevalence of primary degenerative dementia among females.

Sommario

Abbiamo calcolato i tassi di prevalenza della demenza tipo Alzheimer e della demenza multiinfartuale di grado moderato e severo in un campione di popolazione siciliana di 40 anni ed oltre (4337 individui). Per la DAT il tasso di prevalenza è dello 0,80% [LF al 95% 0,56–1,11] nella popolazione di 40 anni ed oltre e diventa pari al 2,42% [LF al 95% 1,69–3,37] nella popolazione che ha raggiunto e superato il 65esimo anno di età.

Per la MID la prevalenza è di 0,34% [LF al 95% 0,19–0,56] nella popolazione di 40 anni ed oltre, mentre nella popolazione di 65 anni ed oltre la prevalenza è dello 0,95% [LF al 95% 0,50–1,62].

La prevalenza dei due tipi di demenza, e per quella tipo Alzheimer in particolare, aumenta significativamente con l'età. Altrettanto significativa è, sempre per la demenza degenerativa primaria, la più elevata prevalenza nel sesso femminile.
