 Drugs Based on Nicotine Could Help in Dementia
New research indicates that nicotine-based drugs may help delay the time that people with dementia enter nursing homes.

Researchers at the King's College London said a new study on mice was able to demonstrate positive effects. They found mice given nicotine were able to carry out specified tasks although they were distracted at the same time.

Previous studies have shown that nicotine can help in boosting boost learning, memory and attention. Nicotine stimulates flow of the hormone adrenaline in the body and this stimulates the brain, the researchers revealed.

"Nicotine, like many other drugs, has multiple effects, some of which are harmful, whereas others may be beneficial," said lead researcher Professor Ian Stolerman. "It may be possible for medicinal chemists to devise compounds that provide some of the beneficial effects of nicotine while cutting out the toxic effects."

The study is due to be presented at the Federation of European Neuroscience Societies conference in Geneva.
