Background/Aims: To evaluate whether visual assessment of medial temporal lobe atrophy (vaMTA) can predict 2-year conversion from mild cognitive impairment (MCI) to dementia and progression of MCI and Alzheimer's disease dementia as measured by the Clinical Dementia Rating Scale Sum of Boxes score (CDR-SB). Methods: vaMTA was performed in 94 patients with MCI according to the Winblad criteria and in 124 patients with AD according to ICD-10 and NINCDS-ADRDA criteria. Demographic data, the Consortium to Establish a Registry for Alzheimer's Disease 10-word delayed recall, APOE ɛ4 status, Cornell Scale for Depression in Dementia, and comorbid hypertension were used as covariates. Results: vaMTA was associated with MCI conversion in an unadjusted model but not in an adjusted model (p = 0.075), where delayed recall and APOE ɛ4 status were significant predictors. With CDR-SB change as the outcome, an interaction between vaMTA and diagnosis was found, but in the adjusted model only delayed recall and age were significant predictors. For vaMTA below 2, the association between vaMTA and CDR-SB change differed between diagnostic groups. Similar results were found based on a trajectory analysis. Conclusion: In adjusted models, memory function, APOE ɛ4 status and age were significant predictors of disease progression, not vaMTA. The association between vaMTA and CDR-SB change was different in patients with MCI and Alzheimer's disease dementia.

Abstract Background Seizures are common accompaniment of neurodegenerative disease. Though, Alzheimer’s disease (AD) is the most common cause, but seizures also occasionally occur in mild cognitive impairment (MCI). Material & methods We studied patients of Subjective Memory Complaints coming to the Department of Neurology of a Tertiary Care Hospital in Northern India from July 2012 to July 2015. A total of 171 patients were studied. Those with a diagnosis of AD/MCI with seizures were taken for the current study. A total of 30 controls with chronic diseases were taken for comparison. Medial Temporal Lobe Atrophy (MTA) Rating was done using Sheleten’s Visual Rating Scale. Results A total of 256 patients were screened and 171 had dementia of Alzheimer’s type (n = 75; M:F = 60:15) and 96 patients had MCI (M:F = 76:20). The mean MMSE of those with AD was 18.5 ± 3.3 was and that of the MCI was 26.6 ± 2.4. A total of 9 cases with AD had seizures and 6 had seizures in MCI group (total n = 15). Moderately strong correlation was obtained between MMSE of AD patients having seizures and MTA scoring. Conclusions Seizures are common in dementia of Alzheimer’s type and not uncommon in MCI. They have the potential to worsen the cognitive profile of the patient and need attention in these patients.
