Nicotine Can Improve Intelligence in Elderly Dementia Patients
Nicotine can improve cognitive abilities in elderly patients with dementia, according to scientific research.

Scientific research has shown that nicotine can improve the intelligence of patients with Alzheimer's disease.


The study was conducted by a group of American scientists led by Paul Newhouse from the Vanderbilt University School of Medicine. The core team comprised of 45 males and 29 females aged 76, whose ability to absorb and perceive new information has slightly declined. The volunteers were observed continuously for six months.


Half of the patients received nicotine patches containing 15 milligrams of nicotine daily, while the rest were given a placebo (with no nicotine). Research shows that those who received nicotine saw an improvement in their symptoms during tests for memory, mental clarity, attention, and reaction time. On the other hand, those who received the placebo saw their condition worsen.

Scientists have observed a significant reduction in the amount of nicotine receptors in the brains of individuals with Alzheimer's disease, which negatively impacts their cognitive abilities.
