Background:
Depression is a growing mental health issue worldwide and considered a challenge for health and economic policy makers with its effect on general health, quality of life, and economic burden, and it is also considered an early symptom of subjective cognitive decline (SCD). Thus, the aim of this study is to investigate the prevalence of depression among a sample of Egyptian male older adults with subjective cognitive decline.

Methods:
Data was collected from 200 male participants from the community and visitors of the outpatient and memory clinics in Ain shams university hospitals in Cairo Egypt, among the age group of 60 years and older. All participants were subjected to demographic data collection, assessment of depression by the Arabic version of Patient Health Questionnaire (PHQ-9), and assessment of cognition by using the Arabic version of Addenbrooke's Cognitive Examination III (ACE III) for the educated group and Rowland Universal Dementia Assessment Scale (RUDAS) for the illiterate group.

Results:
The participants mean age was 65.7 (± 5.9), where 53.5% of them had SCD and 46.5% had Mild Cognitive Impairment (MCI). The total prevalence of depression among all participants was 53.5% and the mild form was the most common 50.0%. The prevalence of depression among the SCD group was 52.3 %, while among MCI group it was 54.8%.

Conclusion:
The prevalence of depression among participants with SCD showed no difference when compared to those with MCI, and the relationship was not statistically significant.
