Studies of people who have mild memory impairment showed that 6 months after being given nicotine, the patient can perform the tasks given and memorize it better. The results of this study was published in the journal Neurology.
"This finding is important because doctors have been the better diagnose dementia or senility when the condition is still in its early stages," said one researcher, Dr.. Paul Newhouse, professor of psychiatry at Vanderbilt University Medical Center.
"The earlier treatment can be done, the better. We want to give care as early as possible and preserve brain function as much as we can," added Newhouse .
Researchers at Vanderbilt studying the effects of nicotine on smokers of 67 people aged 55 and up and have a mild brain malfunctions, a sign of Alzheimer's disease.
Patients with mild brain dysfunction have trouble remembering, trouble with language skills, thinking and reasoning, but not too disruptive of daily activities.
"Nicotine may improve the ability to think for so disguised in the brain chemical, acetylcholine. Nicotine has a three-dimensional structure of the same, making it suitable for acetylcholine receptors. When nicotine stimulates these receptors, these substances act as the nerve signal amplifier," Newhouse said.
"The ability to observe enhanced by stimulating the nicotinic receptors. Patients with Alzheimer's disease lose a lot of nicotinic receptors. The disease attacks the system is very reliable in the ability to remember and pay attention," said Newhouse.
However, nicotine is not always the best option for people who lost their memory because it has mild side effects. Some people experience nausea when given nicotine in high doses. However, participants in the study are generally very good at tolerating nicotine patches.
