NCT02292589

Brief Summary

The purpose of this study is to determine the early effects of transcranial direct current stimulation (tDCS) in patients with mild traumatic brain injury and persistent post concussion syndrome(PPCS) with cognitive deficits in long term episodic memory and executive function(inhibitory control).

Outcome Measures

Primary Outcomes (1)

  • Evidence of improvement of patient's episodic memory and executive function measured by neuropsychological test

    HVLT, Wechsler memory scale, Inhibitory control test(ICT) and Block-tapping test.

    immediately after the stimulation

Study Arms (3)

Frontal Stimulation

EXPERIMENTAL

Left dorsolateral prefrontal cortex stimulation

Device: Frontal Stimulation

Temporal Stimulation

EXPERIMENTAL

Left temporal cortex stimulation

Device: Temporal Stimulation

Sham Stimulation

EXPERIMENTAL

Sham stimulation

Device: Sham Stimulation

Interventions

The patient will receive anodal tDCS on left dorsolateral prefrontal cortex with an intensity of 1.5 mA for 20 minutes.

Frontal Stimulation

The patient will receive anodal tDCS on left temporal cortex with an intensity of 1.5 mA for 20 minutes.

Temporal Stimulation

The patient will receive anodal tDCS over the occipital area for 30 seconds only and then it will be turned off without the patient's knowledge.

Sham Stimulation
