A systematic review of the prevalence of mental and neurocognitive disorders amongst older adults’ populace in Egypt


Background: Mental and neurocognitive disorders are the leading cause of disabilities amongst the older adult populace worldwide. The population of the older adult in Egypt is fast growing. The national census in 2017 revealed a 2.56% increase in the older adult population from the 2006 census, and these figures are expected to double by year 2031. This study aims to review current evidence about the prevalence of mental and neurocognitive disorders amongst older adult population in Egypt. Results: A systematic review was carried out, and 16 studies met the inclusion criteria outlined in this study. Four main mental and neurocognitive disorders were identified: depression, anxiety, cognitive impairment and dementia. The reported prevalence of depression, anxiety, dementia and cognitive impairment are 23.7–74.5%, 14.2–72%, 3.66–39.2% and 1.74–51.4%, respectively. Anxiety and depression were positively correlated with the female gender, increasing age and lower educational status. Also, cognitive impairment and dementia were positively correlated with age, illiteracy or low education. However, there appears to be inconsistencies in the diagnostic tools used. Conclusion: Egypt aging population is growing, and this research brings to forefront the scale of mental and neurocognitive disorders amongst the older adult population. This may help ensure evidence-based initiatives are put in place and priority is given to resource allocation for geriatric mental and neurocognitive disorders in Egypt. Systematic review registration: PROSPERO CRD42018114831.
