Outcome Measures
Primary Outcomes (1)
Apathy Symptoms
Apathy evaluated by Apathy Scale by Starsktein et al, 1992, which consists of 14 items phrased as questions that are to be answered by the caregiver on a four-point Likert scale. The total score range from 0 to 42, with higher scores indicating greater apathy severity. Apathy was assessed at baseline and at the end of the sixth session (second week).
Differences in outcome measure comparing second week to baseline
Study Arms (2)
Sham tDCS
SHAM COMPARATORsham-tDCS application every 2 days for 2 weeks (total of 6 applications)
Transcranial direct current stimulation
EXPERIMENTALtDCS application every 2 days for 2 weeks (total of 6 applications)
Interventions
tDCS 2 mA, dorsolateral pre-frontal cortex
