nicotine drugAlmost everyone knows about the toxic effects and strong addiction risk of Nicotine but now according to some scientists it can boost memory, attention and learning.

Though the effect is not big, dementia patients may get up to six extra months of independent living with it.

In their experiments on rats, positive effects of nicotine have been shown by a team at king’s College London.

They found a boosted animals’ ability in carrying out a task correctly especially when they were distracted.

The animals correct respond rate to the stimuli was around 80% of the time when they were able to give full concentration. There was 5% increase in accuracy rate because of the nicotine.

However, success rate in animals fell around 55% when they were distracted. Nicotine brought it back to the level of almost 85% in this case.

The scientists studied the mechanisms which fortified the effects produced by nicotine.
They noticed how the compound effected on the proteins surface of cells. They also identified role of many key chemicals in the brain like noradernaline and dopamine.

They found that there were just slight biochemical differences in the way the brain is stimulated by the nicotine.

Many other nicotine drugs are also being developed and the researchers are quite hopeful that their work will speed up the discovery of agents that really boost the brain instead of nicotine.

According to lead researcher Professor Ian Stolerman “Like many other drugs, nicotine has several effects, some of them are harmful and some may be beneficial.”

“It is also possible that the medical chemist may devise beneficial compounds and cut out the toxic ones.” Stolerman further adds.

Professor Stolerman also urged that nicotine produced positive effects were not sufficient and might not prove beneficial to most of the people.
