The burden of cognitive impairment in Nigeria: perspectives and research prospects

چکیده

Cognitive impairment represents deficits in memory, thinking, orientation, comprehension,
calculation, learning capacity, language, and judgement. It is seen in Alzheimer’s dementia,
vascular dementia, diabetes mellitus, stroke, and many other conditions. Cognitive impairment
and dementia constitute a huge burden worldwide, with the majority of individuals coming
from low- and middle-income countries including Nigeria. This paper reviews the existing
studies regarding the prevalence and burden of these conditions in Nigeria, highlighting the
dearth of comprehensive nation-wide studies that addresses the situation. The study also brings
perspectives on research ideas and way forward towards improving access to healthcare
services for people living with cognitive impairment and dementia.
