Background: In Egypt, the population of older adults is rapidly growing. The last census in 2017 indicated that older adults numbered 94.8 million, which is a 2.56% increase from the 2006 census. There is growing evidence that the older population is at greater risk for some forms of mental disorders such as depression, dementia, and many more. Objective: This study aims to review the current evidence regarding the prevalence of mental disorders among older adults in Egypt. This will be achieved by estimating the current prevalence of mental disorders and identifying any sociodemographic correlations with mental disorders. Methods: An electronic search of 5 key databases (MEDLINE, PsycINFO, EMBASE, AMED, and PubMed) from their date of inception was conducted. In addition, scans of reference lists and searches of key journals, citations, and relevant internet resources were conducted. Studies were included if they were published in English, point prevalence studies, conducted with older Egyptians aged ≥60 years, and conducted using a validated diagnostic tool to ascertain mental disorders. Studies that did not meet any of these criteria were excluded. Results: This systematic review started in November 2018. The literature search of the 5 databases revealed 343 papers. After screening titles and abstracts, scanning citations and reference lists, and searching internet sources, a total of 38 full-text articles were accessed, of which 16 studies met the eligibility criteria and were included. We are currently in the process of data extraction and synthesis. Conclusions: This research will help bring the scale of mental disorders among older adults in Egypt to the forefront. This may help ensure evidence-based initiatives are established and that priority is given to resource allocation for geriatric mental health in Egypt.
