P 252. A double blind, placebo controlled exploration of the effect of repeated sessions of transcranial alternating current stimulation on tinnitus loudness and distress

A number of recent studies have assessed a neurological basis for tinnitus in the form of abnormal oscillatory activity in the auditory cortex a network of limbic and other brain areas. We sought to modify such activity using alternating current stimulation at different rates in a double blind place...

Description
Summary:A number of recent studies have assessed a neurological basis for tinnitus in the form of abnormal oscillatory activity in the auditory cortex a network of limbic and other brain areas. We sought to modify such activity using alternating current stimulation at different rates in a double blind placebo controlled investigation. The data show a chronic effect of alpha range stimulation (but not low gamma) at temporal lobe electrode sites on both tinnitus intensity and distress. The data can be interpreted in terms of a disruption of the balance between alpha and high gamma activity.
