Dementia prevalence
Benin
A study from Djidja, a rural area, included
502 participants and reported
a prevalence of 2.6% (Table 1).26 The
Community Screening Interview for
Dementia (CSI-D) was used for detection
of dementia. Diagnosis was
confirmed by clinical assessment and
participant-based interview; clinical
dementia was diagnosed according to
DSM-IV criteria and probable or possible
Alzheimer disease was based on
National Institute of Neurological and
Communicative Disorders and Stroke
and the Alzheimer Disease and Related
Disorders Association II (NINCDSADRDA
II) criteria. Analysis on the
basis of dementia subtype revealed
that the prevalence of Alzheimer
disease was 2.2% and accounted for
53.8% of dementia diagnoses in this
population, while vascular dementia
contributed 7.7%. A further 30% of
dementia cases were documented as
possible dementia.
