This trial is testing a treatment called transcranial direct current stimulation (tDCS) to see if it can help improve thinking and memory problems in people with Parkinson's disease. tDCS is a noninvasive procedure that uses a small amount of electrical current applied to the scalp to stimulate brain activity. The researchers believe this treatment may help restore communication between different parts of the brain that are affected by Parkinson's disease.
Many people with Parkinson's disease develop problems with memory, thinking, and concentration as their disease progresses, which can seriously affect their quality of life. Current medications used to treat cognitive problems in other brain diseases have not been proven to work well for the milder thinking problems seen in Parkinson's disease, so researchers are exploring this noninvasive brain stimulation approach as a new option.

You would receive sessions of brain stimulation applied through electrodes placed on your scalp. Some participants will receive the active treatment while others receive a sham (placebo) version to compare results. You will likely undergo brain imaging scans and cognitive testing before and after the treatment to measure any changes in your thinking and memory. The exact number of sessions and total duration of the trial would be determined based on the study protocol.
