Abstract
Alzheimer's disease (AD) patients suffer from cognitive dysfunction. This study assessed the structural magnetic resonance imaging (MRI) scoring among Alzheimer's patients (age ≥18 years) to correlate with dementia severity according to mini-mental state exam (MMSE) scores. This cross-sectional study evaluated Bangladeshi adult AD patients from January 2018 to December 2022 who attended with subjective memory complaints and fulfilled the diagnostic and statistical manual of mental disorders criteria (DSM 5) for diagnosing dementia. The medial temporal lobe atrophy (MTA) and Koedam's score of the atrophy were measured utilising the 1.5 and 3 Tesla Magnetom symphony MRI systems. Of the 62 patients enrolled, the majority (39 cases; 62.9%) were aged over 60 years. Males were more predominant than females, with a male-to-female ratio of 2.6:1, and the moderate MMSE group consisted of 35.6% males and 64.7% females (P = 0.01). Further, MTA score severity is paradoxically associated with the MMSE score (P = 0.005). Additionally, we found a statistically significant negative correlation between the severity of the MMSE and only MTA scores (r = -0.350; 95% CI -0.551 to -0.110; P = 0.005). Structural magnetic resonance imaging among Alzheimer's patients is significantly correlated with the severity of dementia as per mini-mental state exam scores.
