Abstract

Post-Covid complications manifest in most organ systems and functions of the body. The symptoms and their severity change from time to time, in which memory impairment is the most lasting symptom and affects the patient's quality of life. Objective: Describe the clinical characteristics of patients with memory impairment after covid-19 and some related factors. Subjects and methods: Cross-sectional descriptive study. The patients in this study is divided into 2 groups, based on memory impairment with or without global cognitive impairment assessed through the MMSE scale. Results: Out of 152 patients had memory impairment, comfirmed by clinical exam and neuropsychological tests, were included in the study. The most common age group is from 61 - 75 years old (46%). Verbal memory impairment and the proportion of patients with delayed recall are more common than others. 45,39% patients contacting covid from since 3 to 6 months. There is a significant difference (p = 0.025, OR: 0.365, 95% CI from 0.140 to 0.901) of the covid’s severity between the 2 groups. There is a significant difference in the number of vaccinations (p=0.013), and the covid’s severity (p=0.037) between the 2 groups with and without visual memory impairment. Conclusion: Memory impairment in patients after covid 19 in our study, accounting for 65.8%. Mainly verbal memory and delayed memory are impaired. Memory loss is not due to the effects of attention deficit or depression. The main age group is from 61-75, most of them are patients with mild covid, the time after covid is mainly over 3 months. There is an association between the severity of covid and general cognitive decline with memory loss. There is a association between the number of vaccinations and covid’s severity between 2 groups with and without visual memory impairment.
