Non-invasive brain stimulation studies
TMS Aphasia (Biomarkers)
Aphasia is a condition characterized by impairment of the ability to communicate that occurs frequently after stroke. The LCNS is conducting a research study of the effectiveness of Transcranial Magnetic Stimulation (TMS) in improving symptoms of aphasia after stroke. This technique has been shown to provide limited but sustained improvement in naming tasks after repeated sessions. The biomarkers study hopes to identify markers (biological and physiological) of neural plasticity that might explain differing recovery profiles among aphasic patients. Potential participants should be between the ages of 18 and 75 years of age, and have suffered a single stroke on the left side of the brain 6 months prior to participation.
tDCS Primary Progressive Aphasia (PPA)
Primary Progressive Aphasia (PPA) is a form of cognitive impairment characterized by the progressive loss of language function. The LCNS is conducting a research study of the effectiveness of Transcranial Direct Current Stimulation (tDCS) in improving symptoms of PPA. We are currently exploring the possible beneficial effects of tDCS for patients with PPA.
tDCS Multiple Sclerosis
Dr. Hamilton is studying the effect of transcranial direct current stimulation (tDCS) on general cognition and memory performance in Multiple Sclerosis (MS) Disease. tDCS involves the application of weak currents to the scalp which modulates the underlying cortical activity. By stimulating or inhibiting different brain regions, Dr. Hamilton hopes to alter the profile of cognitive decline experienced by patients suffering from MS.
We are currently investigating the effect of Transcranial Magnetic Stimulation on motor processing and propioception.
