Design outcomes

Primary

MeasureTime frame
1. Neuropsychological variables measured using a combination of selected subtests from the WMS III IND, NIMHANS Neuropsychological Battery for Adults and D-KEFS subtests at baseline, 20 days to 1 month, and 6 months from the last assessment 2. Quality of life measured using QOLIE-31 at baseline, 20 days to 1 month and 6 months from the last assessment 3. Mood states of anxiety measured using GAD-7 and depression using PHQ-9 at baseline, 20 days to 1 month and 6 months from the last assessment 4. Diffusion tensor imaging for a selected group of participants using 3T-MRI at baseline and 20 days to 1 month

Secondary

MeasureTime frame
1. Left versus right ATL-AH neuropsychological profiles measured using a combination of WMS III IND, NIMHANS Neuropsychology Battery for Adults and DKEFS subtests at baseline 2. Neuropsychological variables compared between the intervention group and the healthy control group using WMS III IND, NIMHANS Neuropsychology Battery for Adults and D-KEFS subtests to establish gains/deficits post retraining at baseline and after the intervention 3. Levels of cognitive estimation/subjective confidence levels in intervention and treatment-as-usual groups measured using subjective confidence ratings at baseline, 2nd assessment and follow-up
