Do scientists determine the advantages of nicotine?

Researchers have shown that nicotine may have some value in the fight against late depression.

Some elderly people with depression in late (LLD) do not respond to antidepressants at all. A new study (see article at the end of the original link) showed that nicotinic acetylcholine receptor (nAChR) agonists including nicotine may have curative effect on depression.

Depression can cause symptoms such as low emotion and poor cognitive ability in the elderly over 60 years. Nicotine is known to enhance cognitive function. According to the researchers in animal studies, the drug can effectively improve the depression behavior in animal models, and help to improve the mood of patients with depression.

Researchers have proposed a clinical trial plan for future research of nicotine that is to test whether it will has a positive effect on the treatment of elderly depression in late by using nicotine patches in clinical trials, such as the recently popular NRT Nicoderm patch.

    Three of the study's authors are from Vanderbilt University in Tennessee, including Vanderbilt Paul Neuhaus of the center for cognitive medicine (Paul Newhouse) - he had done a lot of research of nicotine. In 2008, Paul showed that patients with ADHD (attention deficit hyperactivity disorder) who used nicotine patches were able to perform more cognitive tasks than patients with placebo patch. In 2015, Paul had begun a study of nicotine patches to alleviate symptoms of amnesia in elderly people with mild cognitive impairment.
