Prevalence of dementia and dementia subtypes among community-dwelling elderly people in northern Nigeria.
Summary of "Prevalence of dementia and dementia subtypes among community-dwelling elderly people in northern Nigeria."
ABSTRACTBackground: Dementia has important public health implications. The magnitude of the problem remains largely unknown in the developing countries.Methods: Three hundred and twenty-two community dwelling elderly persons and their caregivers in Zaria, Northern-Nigeria were enrolled in this study. They were interviewed using Community Screening Interview for Dementia (CSI-D), Consortium to Establish Registry for Alzheimer's disease (CERAD), Stick Design Test (SDT), Blessed Dementia Scale and a sociodemographic questionnaire. The data obtained were analyzed using the Statistical Package for Social Sciences version 15 for Windows. Diagnosis was based on fulfilling criteria for dementia in both the International Classification of Disease, 10th edition and the Diagnostic and Statistical Manual, 4th edition.Results: The mean age of the subjects was 75.5 +/- 9.4 years. The prevalence of dementia was 2.79% (CI 1-4.58%). Alzheimer's disease constituted 66.67% of all the cases of dementia in this community. Age was the only demographic factor associated with dementia.Conclusion: The prevalence rates of dementia and dementia subtypes in the developing countries are similar using standard diagnostic criteria and methods.

Medical and Biotech [MESH] Definitions
Frontotemporal Lobar Degeneration
Heterogeneous group of neurodegenerative disorders characterized by frontal and temporal lobe atrophy associated with neuronal loss, gliosis, and dementia. Patients exhibit progressive changes in social, behavioral, and/or language function. Multiple subtypes or forms are recognized based on presence or absence of TAU PROTEIN inclusions. FTLD includes three clinical syndromes: FRONTOTEMPORAL DEMENTIA, semantic dementia, and PRIMARY PROGRESSIVE NONFLUENT APHASIA.
Dementia, Vascular
An imprecise term referring to dementia associated with CEREBROVASCULAR DISORDERS, including CEREBRAL INFARCTION (single or multiple), and conditions associated with chronic BRAIN ISCHEMIA. Diffuse, cortical, and subcortical subtypes have been described. (From Gerontol Geriatr 1998 Feb;31(1):36-44)
Frontotemporal Dementia
The most common clinical form of FRONTOTEMPORAL LOBAR DEGENERATION, this dementia presents with personality and behavioral changes often associated with disinhibition, apathy, and lack of insight.
Diffuse Neurofibrillary Tangles With Calcification
A form of presenile DEMENTIA characterized by cortical dementia, NEUROFIBRILLARY TANGLES without SENILE PLAQUES, Fahr's type CALCINOSIS, and ATROPHY in frontotemporal or TEMPORAL LOBE.
Delirium, Dementia, Amnestic, Cognitive Disorders
Cognitive disorders including delirium, dementia, and other cognitive disorders. These may be the result of substance use, trauma, or other causes.
