Abstract

To study electroencephalography (EEG) changes in patients with cortical dementias (Alzheimer's disease [AD] and frontotemporal dementia (FTD). (1) To correlate EEG changes with clinical severity of dementia as assessed by rating scales. (2) To correlate global gray matter volume (GGMV) with EEG scores and clinical severity rating scales. This is a prospective cross-sectional study involving patients fulfilling the criteria for Probable AD and FTD. A total of thirty patients (20 = FTD, 10 = AD) underwent detailed neuropsychological evaluation, dementia rating scales, EEG, and magnetic resonance imaging. Five EEG parameters were acquired and each parameter is scaled and the total score was compared with neuropsychological parameters and GGMV. For FTD, the mean age of patients was 58.85 ± 6.87, mean mini-mental state examination score was 13.30 ± 6.33, Hindi mental state examination: 14.35 ± 6.28, mean grant total EEG score (GTES): 7.80 ± 5.39, and mean GGMV: 464580.76 ± 52127 mm(3) and for AD, the same were 69.50 ± 8.59, 12.90 ± 5.56, 14.20 ± 5.31, 9.80 ± 5.29, and 483208 ± 47371.5 mm(3), respectively. GTES for mild, moderate, and severe FTD are 2.33 ± 1.528, 6.00 ± 3.162, and 10.70 ± 5.677 and for AD it is 4, 7.50 ± 4.041, 15 ± ...Continue Reading

Alzheimer's Disease: Neuroimaging

Neuroimaging can help identify pathological hallmarks of Alzheimer's disease (AD). Here is the latest research on neuroimaging modalities, including magnetic resonance imaging and positron emission tomography, in AD.
