Background: Pneumonia is a leading source of illness and mortality throughout the world. The majority of this research agrees on the possibility of a link between pneumonia and cognitive impairment or dementia. Objective: The effect of pneumonia on cognitive impairment was examined in this study. Materials and Methods: A matched cohort study was carried out using hospitalization data from Green Life Medical College and Hospital in Dhaka from January 2020 to November 2022, with diagnostic data classified according to the International Classification of Diseases, 10th Revision (ICD-10). Adults (18 years old) who had their first hospitalization for pneumonia throughout the study period were included. Patients were excluded if they a) had been registered with the practice for less than a year prior to admission (15), b) had hospital-acquired pneumonia (admission for at least a day in the 10 days preceding the index admission), or c) had pre-existing cognitive impairment or dementia. Controls were given the same index date as their matched pneumonia patients. Results: In the pneumonia group, half of the patients (50.0%) were determined to be at low risk, 14 (28.0%) were at moderate risk, and 11 (22.0%) were at high risk of pneumonia severity index. In terms of SMMSE scores, 5(10.0%) patients in the pneumonia group and 1(2.0%) in the control group had severe cognitive impairment. The difference between the two groups was statistically significant (p <0.05). Conclusion: In conclusion, persons who recover from pneumonia hospitalization had a higher likelihood of a new diagnosis of cognitive impairment than the general population.
