We subjected each proband to amodified form of the Mini Mental State Examination test. Subjectsscored 21 or less were investigated according to a standardizedprotocol. We found 90 demented subjects yielding a crude prevalenceratio (case per 100 population over the age of 60) of 4.5, Adiagnosis of subtypes of dementia was reached in 83 cases. Prevalenceratios for dementia subtypes were 2.2 for AD, 0.95 for multi-infarctdementia, 0.55 for mixed dementias and 0.45 for secondary dementias.Age-specific prevalence tends to be doubled every 5 years.Occupation, level of education and residence did not affect theprevalence or severity of dementia.
