Now, specificity of the currents are improved with tDCS targeting brain areas such as the prefrontal cortex and auditory cortex for auditory hallucinations. Second, the methods are more varied, including tDCS, ECT, and transcranial magnetic stimulation, which uses a magnetic coil placed above the head to generate an electric current into the brain region below. Third, the side effects are no longer as severe so it can be a treatment of choice for recalcitrant depression.
These methods are being found to treat hallucinations, migraines, PTSD, and severe mood disorders. With many of the treatment options prohibitively expensive, tDCS may provide a more affordable and transportable approach. The process is a long way from being finalized: variables continued to be tweaked, including size and placement of electrodes as well as amplitude and duration of current.
As I’ve written in the past, I see mental health disorders as an autoimmune disease of the head: destroying from within. For people faced with impaired functioning due to schizophrenia or depression or PTSD, who haven’t experienced relief from psychotropic medications or talk therapy, a new approach to treatment is vital. Brain stimulation becoming safer and more fine-tuned and accessible than it has been in the past is groundbreaking. People have the chance to get their brain back.
