Transcranial Direct Current Stimulation (tDCS) is effective in reducing symptoms of anxiety in various anxiety disorders such as Obsessive Compulsive Disorder (OCD), Panic Disorder, Phobia, Post Traumatic Stress Disorder (PTSD), Generalized Anxiety Disorder (GAD), etc.
tDCS can be beneficial as a mode of treatment for people with anxiety disorders who are treatment-resistant, that is, do not respond well to conventional methods of treatment such as pharmacotherapy and psychotherapy. It is considered most effective when used in conjunction with other treatment options.
The number of sessions is variable and depends on the individual’s severity of anxiety disorder and their response to the treatment.
