Treatment for Acute Fear
“Transcranial Direct Current Stimulation (tDCS) as a Treatment for Acute Fear”
Locus coeruleus (LC) norepinephrine (NE) neuron activity has been convincingly linked to regulation of acute fear. This study will address whether LC NE activity examined through pupil measures will reflect carbon dioxide (CO2) induced fear-responses in humans and if transcranial direct current stimulation (tDCS) can mitigate these effects. A 2 year R21 phase establishing feasibility, tolerability, safety, and proof-of-concept (POC) in terms of capacity to engage LC NE neurons with tDCS, followed by a 3 year R33 parallel-group, double-blind, randomized, controlled trial will determine the degree to which engaging LC NE neurons with tDCS improves clinical symptoms.
Device - NeuroConn Direct Current stimulator Multiple Channel -4
(tDCS) will be administered with a multichannel tDCS device that can be programmed so that the operator doesn't know the combination of electrodes being used for stimulation, and, thereby allow double-blinding. The active tDCS electrode configuration to be used will be determined with the 3 round iterative procedure described above; based on electric field modeling and personalized electrical dose titration to find the lowest dose that is well-tolerated and engages the target in terms of inhibit ...read more on ClinicalTrials.org
