Nicotine Improves Brain Function In Schizophrenics

An anonymous reader suggests a Cosmos Magazine note that nicotine has been shown to enhance attention and memory in schizophrenics. Research is now aimed at developing new treatments that could relieve symptoms and prevent smoking-related deaths. "A strong link between schizophrenia and smoking — with over three times as many schizophrenics smoking (70 to 90%) as the population at large — prompted scientists to investigate the link. Researchers led by Ruth Barr, a psychiatrist at Queen's University in Belfast, Northern Ireland, set out to find if the nicotine in cigarettes was helping patients to overcome their difficulties with cognitive function, such as planning and memory in social and work settings."

    I'll simply start telling folks I'm a schizophrenic to justify my pack a day habit.

    Would you want to see what happens when I try to quit?

    Nicotine itself is unlikely to make an effective treatment, because of its side effects and addictive potential, but drugs known as nicotinic agonists, which target nicotine receptors in the brain, are front runners in the challenge to find an effective replacement.

    Haha. So rather than use a cheap natural solution it's better to get the expensive patented synthetic stuff. Riiiiiight... Now I see.

      There is research that suggests that nicotine completely rewires the pleasure centers of the brain (to make them dependent on nicotine)

      Then again, human ingenuity knows no bounds when it comes to pleasure and nicotine. Look what Clinton and Monica managed to do with that cigar.

    As I suffer from schizophrenia myself I know how bad your memory can get because of it. Maybe there is a connection between I stopped smoking and I (finally) got a diagnose on what was wrong with me. Perhaps it made the symptoms clearer?

    I sure hope it is correct and doesn't get debunked.

    Nicotine can also be a potent self-medication for other mental health issues. For example, nicotine (as a stimulant) is often used by those with ADHD to self-medicate.

    Schizophrenics have been said to "self medicate" with nicotine for YEARS. When I started in the field in 1998 it was already a conclusion everyone was working under.

    Schizophrenia Bulletin 1998 24(2):189-202;

    A series of human and animal investigations has suggested that altered expression and function of the {alpha}7-nicotinic cholinergic receptor may be responsible for the auditory sensory gating deficit characterized in schizophrenia patients and their relatives as diminished suppression of an auditory-evoked response (P50) to repeated stimuli. This finding, in conjunction with evidence for familial transmission of this sensory gating deficit, suggests a pathogenic role of the gene for the {alpha}7-nicotinic receptor in schizophrenia. This article considers the possible effects of this dysfunction in a broader context. Not only is this dysfunction consistent with difficulties in sensory gating, but it might also pre dispose patients to problems with learning efficiency and accuracy. Such learning problems could underlie schizophrenia patients' delusional thinking, hallucinations, and social dysfunction. In addition, heavy smoking in many schizophrenia patients is consistent with the high concentration of nicotine necessary to activate the receptor and with the receptor's extremely rapid desensitization. Finally, the receptor's possible role in cell growth and differentiation should be considered in connection with developmental deficits and other cellular abnormalities in schizophrenia.

    I would have thought smoking would bring on mental problems in the first place rather than be a palliative.

    Nicotine improves brain function even in non-schizophrenics, because it binds to acetylcholine receptors. Of course, the most common delivery methods have one or two negative side effects.

    Scientific American also published an article in 2003 suggesting that a by-product of nicotine can slow the onset of Alzheimer's disease. It does not take a nicotine-addict to see that CNS stimulants can have beneficial effects on brain function.

    Nicotine sharpens the mind while simultaneously relaxing the muscles. That's why it's so addictive. Duh.

    In fact, personally, I blame the lack of smoking by people for the general dumbing-down of everyone and everything including Slashdot. Oh? You doubt me? Ha! Just go read some of the threads on Slashdot from back in the 40s and 50s and compare it to the drivel of today. Notice, in particular, the civility of discourse and the lack of Linux/Apple/Microsoft fanbois. You'll see.

    In reply to the question on smoking:

    At 19, I was stupid and didn't think of anything aside from smoking as a solution. After a few years and not being able to run like I used to, I started looking for another option. The gum made my mouth feel rotten, and something about the delivery mechanism of the patch (the steady delivery, perhaps?) didn't give me the "kick" I was, frankly, addicted to.

    Technology, though, is a hell of a thing. These days, I use a cigarette-sized atomizer. It delivers nicotine, water vapor, propelyne glycol, and optional flavoring on inhales. Nothing else--no burning, no other carcinogens. Charges by USB, one cartridge has 16mg nicotine and lasts 150 puffs, so it's trivial to determine dosage. I still call it "smoking" though it's not Sure, start up cost is high, but my health prefers as few carcinogens as possible. Also, it's less obnoxious to people around me. Anyone in the same boat should seriously look at them--handles the fixation as well as delivering nicotine.

    Have to admit, now and then I do enjoy a good cigar, though.
