Transcranial Direct Current Stimulation (tDCS) in Post-Stroke Working

Status Terminated

Clinical Trial Summary

The purpose of this study is to test the effects of tDCS (Transcranial Direct Current Stimulation) on stroke patients with working memory problems.

Clinical Trial Description

After having a stroke, people often have trouble remembering to do something, solving problems, or following conversations. They can also have trouble concentrating, following instructions, and multitasking. These can all due to the stroke affecting a brain function called "working memory". Working memory is defined as the ability to hold a thought in one's mind for a few seconds in order to remember a task or solve a problem. People have difficulty returning to their normal lives because of these working memory problems. Currently, there no proven medical treatments for working memory problems.

Transcranial direct current stimulation (tDCS) is a painless, noninvasive brain stimulation technique that has been shown in some studies to improve working memory in healthy subjects. TDCS involves sending a weak electrical current through the head, thereby exciting the brain underneath. TDCS is not an FDA-approved treatment for any condition, but previous trials have shown it may benefit movement and language recovery after stroke, as well as improve thinking ability. Studies have shown tDCS to be very safe with no serious adverse events in over 10,000 subjects studied.

This pilot study will involve four visits to Stony Brook University Hospital. The first is a baseline session where subjects perform all outcome measures but no tDCS is performed other than for familiarization. The other three sessions are the stimulation sessions where subjects undergo the intervention for 20 minutes to test tDCS effects on the outcome measures. The effects of tDCS for a single session are expected to only last for few hours. Subjects will be receiving all three different types of stimulation. If this study finds a short term benefit of tDCS for post-stroke working memory deficits, it will support a full clinical trial where multiple sessions of tDCS will be given and may provide a long-term benefit. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
