Caring for individuals with dementia: the Nigerian experience

Area of Science:

• Epidemiology
• Neurodegenerative Diseases
• Public Health

Background:

• Dementia and Alzheimer's disease (AD) prevalence is lower in developing countries compared to industrialized ones.
• Resource limitations in developing nations necessitate effective home-based care strategies for dementia patients.
• Cultural contexts, particularly extended family support, favor home care models.

Purpose of the Study:

• To explore dementia prevalence and care challenges in developing countries.
• To highlight the role of hypertension as a comorbidity in dementia and AD.
• To present a caregiver support model adaptable to African communities.

Main Methods:

• Analysis of epidemiological data from cross-cultural studies.
• Identification of medical comorbidities in dementia patients, focusing on hypertension.
• Evaluation of caregiver burden and stress levels.
• Application of the Indianapolis-Ibadan Dementia Study model.

Main Results:

• Hypertension is a frequent comorbidity in dementia patients, with approximately one-third of AD subjects being hypertensive, supporting the vascular hypothesis.
• Caregivers experience significant behavioral disturbances and stress.
• The Indianapolis-Ibadan Dementia Study model, incorporating home visits and caregiver empowerment, shows promise.

Conclusions:

• Home care, supported by cultural norms and family structures, is a viable approach for dementia care in developing countries.
• Public policies must be developed to support elderly care.
• The demonstrated caregiver support model offers a practical framework for improving dementia care in African communities and beyond.
