| Abstract | ||||
| Background: Subjective cognitive decline (SCD) is one of the early warning signs of objective cognition impairment, and dementia and is associated with higher rates of sleep disorders across various cross-sectional and longitudinal cohort studies. Aim: To assess the prevalence of sleep disorders in elderly females complaining of subjective cognitive decline. Methods: A cross sectional study involving 207 elderly females attending outpatient clinics and memory clinics at Ain Shams university hospitals. Demographic data of the participants were collected. Screening of SCD was done first using Alzheimer Dementia 8 item scale (AD8) and followed by assessment of cognition by Addenbrooke’s cognitive Examination Ш (ACE Ш) for literate personnel and Rowland Universal Dementia Assessment Scale (RUDAS) for illiterate personnel and sleep disorders using Pittsburgh sleep quality index (PSQI). Results: screening of SCD was done by AD8 and participants with cut off score ≥2 indicating SCD were included in the study. Further assessment revealed that 31.2% & 54.6% of the studied sample (literate and illiterate respectively) who reported SCD had MCI. There was a statistically significant negative impact of sleeping problems on cognitive functions of participants (P value 0.04). Of those with SCD and MCI 91.6% complained of sleeping problems, with sleep quality index (8.4±1.9). While those with SCD and normal cognition complaining of sleep problems were 76.8% of this group with sleep quality index of (7.5±2.2). Conclusion: SCD is significantly associated with sleep disorders. A reciprocal relation is present between sleep disorders and SCD. | ||||
