A Study of Cerebral Perfusion With tDCS in Chronic Hypoperfusion

Augmenting Cerebral Perfusion With Transcranial Direct Current Stimulation (tDCS) in Chronic Hypoperfusion States

This study is being done to examine whether transcranial direct current stimulation (tDCS) will increase cerebral blood flow which may provide a clinical benefit such as improving cognitive impairment.

Inclusion Criteria:

• Vasculopathy leading to imaging evidence of hypoperfusion
• Cognitive impairment

Exclusion Criteria:

• Pregnancy
• Contraindication to MRI or tDCS including metallic implanted objects.
• Medical instability or inability to cooperate during the study as assessed by the treating physician to participate in the study.
