Pythagorean said:Niccotine does help brain processing in Alzheimers patients: (don't know if it's true for parkinsons)
Alzheimers suffer reduced acytocholine levels, acytocholine acts on niccotinic receptors, so it's no surprise that niccotine can "take the place" of acytocholine.
Parkinson's have excess acytocholine, so not sure how it works.
But these were both presented in my Abnormal Psychology textbook, with references (which I don't have in front of me right now). But if you're really intersted, just google scholar "nicotine alzheimers". There's all kinds of studies on it. It's pretty well known among clinical psychologists of cognitive disorders.
I sitll want to quit, even though Alzheimer's runs in my family (my grandfather who died from it smoked anyhow... didn't stop it, though never know how it helped him hold onto integrated cognition longer)
Furthermore, if you seek nicotine as a treatment, you don't need to smoke it. You can safely digest lower levels of nicotine.
Pythagorean said:that's why I included the last line in my post, the issue of smoking is irrelevant to the issue of medicinal nicotine. Inhaling any smoke is bad for you.
nismaratwork said:Oh I know, but let's be honest, most people who get their nicotine smoke it. I'm wondering how it all stacks up, not in general, but specifically as both relate to the brain.

There was a test I recall where they tested inhibition responses of smokers (since there was less activity in PFC) but they were just as quick at the test as non-smokers. It was called the stop-signal test. However, since there's less activity in the PFC, it does raise a red fag of sorts (not that activity necessarily corresponds to intelligence; an epileptic seizure involves lots of activity)

Nicotine is a stimulant that enters the body through smoking or other forms of tobacco use. It quickly travels to the brain, where it binds to receptors on nerve cells and triggers the release of dopamine, a neurotransmitter that is associated with pleasure and reward. This creates a temporary feeling of pleasure and relaxation, which can lead to addiction.
Long-term nicotine use has been linked to a variety of health problems, including increased risk of heart disease, stroke, and lung cancer. It can also cause damage to the respiratory and cardiovascular systems, as well as harm to the developing brains of adolescents and fetuses.
Yes, nicotine is highly addictive. It activates the reward pathway in the brain, leading to cravings and withdrawal symptoms when use is stopped. This makes it difficult for individuals to quit using nicotine products, such as cigarettes and e-cigarettes.
While nicotine itself is not considered a beneficial substance, some research has shown that it may have potential therapeutic effects for certain medical conditions, such as Parkinson's disease and ulcerative colitis. However, these potential benefits must be weighed against the numerous negative effects of nicotine on the body.
No, nicotine is a harmful and addictive substance that should not be used recreationally. Even in small doses, it can have negative effects on the body and can lead to addiction. The best way to avoid these risks is to not use nicotine products at all.
