Can a Nicotine Patch Sharpen Thinking in Mild Cognitive Impairment?
Dr. Kumar’s Take
This 6 month trial asked a simple question: can a nicotine patch help thinking in people with mild cognitive impairment. The answer is a careful yes for test scores and a no for overall clinical change. People on nicotine showed better attention and some memory on computer tests. Clinicians did not rate patients as clearly better in daily life. Side effects were mostly mild.
My bottom line: this is interesting biology, not a green light for self treatment. If you or a loved one has memory concerns, focus first on proven pillars like sleep, exercise, blood pressure control, and hearing support. If you are curious about research use of nicotine, talk with your clinician and avoid over the counter experiments.
