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
"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
