Iranian researchers at Amirkabir University have developed brain stimulator transcranial direct current stimulation (tDCS) devices which can be used in treatment of Parkinson’s disease, according to Mehr news agency.

Golnaz Baghdadi, Bioelectric PhD student at Biomedical Engineering Department of Amirkabir University of Technology (AUT), said that the device has been designed and developed inside Iran for the first time by a team at AUT led by Dr. Farzad Tohidkhah, rector of the Biomedical Engineering Department.

“The brain stimulator tDCS device is used in treatment of depression, on people suffering from attention deficit disorder or patients with Parkinson’s disease,” she said.

Baghdadi explained the performance of the device, saying that it can stimulate the brain through delivering a constant, low current to the brain area of interest via electrodes on the scalp.

After a few sessions, she said, the patient will start showing signs of improvement.

“The effects will last up to three to four months, and then the patient needs to go back to the clinic so that the device will be set on a specific dosage to be used by the patient at home,” she added.

“Compared to the foreign version, the Iranian tDCS device is programmable by computer, can store data via a flash drive, has a touch screen for ease of use, and is more affordable.”
