Patients with Mental Disorders Now have
an Alternative to Electroshock Therapy!
an Alternative to Electroshock Therapy!
Various neuropsychological
disorders such as Schizophrenia, Depression, Alzheimer’s, Migraine,
Parkinsonism etc have made it difficult for patients to lead a normal life and
the number is only increasing by the day.
But there have also been
many path breaking innovative treatments to have come to the rescue. One such
innovative treatment in Neuropsychiatry is the Transcranial Direct Current
Stimulation also known as tDCS.
What exactly
is tDCS?
Transcranial Direct
Current Stimulation (tDCS) is a non-invasive technique that is mainly used to modulate the brain
function with the help of electric current and thus subsequently modifies human
behavior. This treatment is pretty different than conventional Electroshock
Therapy.
tDCS plays a crucial role in
enhancing brain function and subsequently modifying human behavior. It benefits in many disorders such as
Schizophrenia, Depression, Obsessive-Compulsive Disorder, Alzheimer’s,
Migraine, Parkinsonism etc. It is also pretty effective in reducing impulsivity
and distractibility in persons with Attention Deficit Disorder.
In many countries, tDCS is
used by healthy people with no mental disorder, to boost Verbal & Motor
Skills, to enhance the Cognitive Skills like Learning, Memory and even General
Functionality of their brains.
How does tDCS
function?
During treatment a tDCS
machine passes small electric current using non-metallic rubber electrodes with
saline soaked sponges placed at desired areas on the head. The current passes
through the scalp to modulate the brain function. In this the skin and the
electrodes need to be prepared. The careful placement of electrodes is one of
the crucial parts of tDCS. The duration of the change brought in by tDCS
depends both on the length of stimulation and the intensity of stimulation.
How different
is tDCS from Electroshock Therapy (ECT):
tDCS also does not require
anesthesia unlike ECT and can be administered with a patient sitting in any
comfortable chair at the Doctor’s clinic.
ECT uses electrical currents
a thousand times greater than tDCS. Patients receiving tDCS generally report
nothing more than a mild tingling or itchy feeling from under the electrode
during the stimulation. These sensations also disappear immediately after the
current is turned off.
tDCS only influences the
area of the cortical brain directly beneath the electrode whereas ECT affects
the functioning of the entire brain. The known side effects of ECT may include confusion
or memory loss to some degree. tDCS has shown no such side effects and hence is
a lot safer method of treatment.
The effects of tDCS remain
active long after the stimulation has ended.
Dr Rohan Jahagirdar states, “Treatment using tDCS
technique is safe, non-invasive, painless, easy to administer and also
relatively inexpensive. We have got this technique here in Pune for the first time in a bid to
help as many patients as we can to resume normal life as soon as possible.”
He adds “The basic treatment consists
of a series of 15 consecutive Sessions of 15 minutes each. Sometimes a second
series of sessions may be necessary to obtain maximum improvement in symptoms
being treated.”
Dr Rohan Jahagirdar has
undergone an extensive training in Transcranial Direct Current Stimulation
(tDCS) Treatment at National
Institute of Mental Health and Neuroscience (NIMHANS), Bangalore
