Tests of mental function typically rely on language and the written word. Therefore, it is difficult to assess mental function across populations with low formal education levels and cultural and language barriers.

The 10/66 Dementia Research Group has developed a diagnostic panel that is effective across education levels and across cultures. The panel includes:

•The Geriatric Mental State - a clinical interview covering symptoms.

•The Community Screening Instrument for Dementia (CSI-D) - a test of memory, concentration, language and orientation; and a caregiver interview.

•CERAD 10 Word List - verbal 10 word recall test.

•

Pilot studies have been completed worldwide, successfully identifying 94% of dementia cases correctly. It worked equally well in Indian, Chinese and Latin American countries, demonstrating effectiveness with language and cultural diversity.
