Trend: From brain surgery towards non-invasive brain stimulation therapies




When Michelle Lane was inca­pac­i­tat­ed by Parkin­son’s dis­ease, her best option was brain surgery. Elec­tri­cal leads were sur­gi­cal­ly implant­ed into her skull, and a pace­mak­er-like device installed to deliv­er elec­tri­cal sig­nals to the move­ment region of the brain.

Now researchers from Johns Hop­kins Uni­ver­si­ty are devel­op­ing a way to achieve the same effect with­out surgery…It uses exter­nal elec­trodes to deliv­er a low-lev­el cur­rent to the motor cor­tex of the brain, and is based on…a non­in­va­sive brain stim­u­la­tion ther­a­py called tran­scra­nial direct cur­rent stim­u­la­tion. In the ther­a­py two spongy elec­trodes are put on the skull and a small, some­times imper­cep­ti­ble cur­rent is sent through them to a tar­get region of the brain.

Since the STIM­band is just a pro­to­type, there will need to be more test­ing to fur­ther ver­i­fy its effi­ca­cy and to rule out any place­bo effect…for those with Parkinson’s it might be very help­ful to use in con­junc­tion with med­ica­tion, since one modal­i­ty would not inter­fere with the other.”
