Correlates of memory complaints and personality, depression, and anxiety in a memory clinic

The aim of the study was to find whether there is an association between subjective memory complaint and memory impairment and probable underlying psychological conditions. A total of 90 patients with subjective memory complaint enrolled in this study. Short history and demographic information were obtained and then the patients underwent memory and mental health assessments, using Wechsler Memory Scale (WMS), Hospital Anxiety and Depression Scale (HADS) and Minnesota Multiphasic Personality Inventory (MMPI) test tools. The mean age of the participants was 52.31 ± 17.97. Forty patients out of 90 (44.4%) were male. The prevalence of depression, anxiety and memory impairment was 10%, 12.2%, and 28.8%, respectively. Memory impairment has only shown a significant association with the presence of anxiety disorder according to the HADS findings (P=0.001). Regarding the MMPI, considerable differences were observed in the average grade of hysteria among patients with and without memory impairment: 8.38 ± 2.27 vs. 4.35 ± 1.96. There was also significant statistical association between the average score of depression on the MMPI in patients with and without memory impairment that were 13.7 ± 3.33 and 8.31 ±3.86, (P=0.03). The result of the current study shows that underlying psychological conditions such as anxiety, depression, and histrionic personality are associated with memory impairment.
