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."

    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.

      Smoking is bad for a multitude of reasons. Additionally, nicotine interacts with some anti-psychotics (clozapine for instance) causing both the nicotine and clozapine to have attenuated effects. No Dr. would ever recommend smoking. I would only recommend it if you lived in world with no other medication options.

      Nicotinic interactions with antipsychotic drugs, models of schizophrenia and impacts on cognitive function

      Department of Psychiatry and Behavioral Sciences, Duke University Medical Center, Durham, NC 27710, USA

      People with schizophrenia often have substantial cognitive impairments, which may be related to nicotinic receptor deficits, (α7 and α4Î2), documented in the brains of people with schizophrenia. The large majority of people with schizophrenia smoke cigarettes. Thus, nicotinic interactions with antipsychotic drugs are widespread. Complementary co-therapies of novel nicotinic ligands are being developed to add to antipsychotic therapy to treat the cognitive impairment of schizophrenia. Thus, it is critical to understand the interaction between nicotinic treatments and antipsychotic drugs. Nicotinic interactions with antipsychotic drugs, are complex since both nicotine and antipsychotics have complex actions. Nicotine stimulates and desensitizes nicotinic receptors of various subtypes and potentiates the release of different neurotransmitters. Antipsychotics also act on a verity of receptor systems. For example, clozapine acts as an antagonist at a variety of neurotransmitter receptors such as those for dopamine, serotonin, norepinepherine and histamine. In a series of studies, we have found that in normally functioning rats, moderate doses of clozapine impair working memory and that clozapine blocks nicotine-induced memory and attentional improvement. Clozapine and nicotine can attenuate each other's beneficial effects in reversing the memory impairment caused by the psychototmimetic drug dizocilpine. A key to the clozapine-induced attenuation of nicotine-induced cognitive improvement appears to be its 5HT2 antagonist properties. The selective 5HT2 antagonist ketanserin has a similar action of blocking nicotine-induced memory and attentional improvements. It is important to consider the interactions between nicotinic and antipsychotic drugs to develop the most efficacious treatment for cognitive improvement in people with schizophrenia.

    Nicotine's affects on the mind and body have been known for quite some time, but that it can CLINICALLY help schizophrenics is a step forward for them (drugs tend to be testy with psych patients). Quite a few of our medicines come from plants, and nicotine in itself is not very harmful (I administer more dangerous drugs on the back of the ambulance). Just remember, it is the SMOKE AND ADDITIVES that cause the cancer and COPD... not the nicotine itself. Because it is tied to smoking nicotine has a bad stigma, but we have already refined it for medicinal purposes.

    Schizophrenia isn't very well defined and, to further complicate things, there are diagnoses that couple schizophrenia with other disorders that, in turn, aren't well defined. Two current, prevalent theories, not necessarily at odds, suggest on one hand that schizophrenia is tied directly into the dopamine system, and, OTOH, that schizophrenia is a disorder arising from the brain's architecture. The first theory usually involves medications that dampen the dopamine system but that have, literally, potentially killer, side effects. The idea that schizophrenia is tied to the brain's architecture is broad and incorporates ideas that there are genetic, congenial causes for schizophrenia that can be exacerbated by environmental factors, such as physical, or, emotional insult or forms of neglect. Concurrent with the second view is that the small, inter neurons that connect long range disparate neural pathways don't function up to par in schizophrenics. Smoking cigarettes is prevalent among schizophrenics but given the lack of consensus as to what constitutes schizophrenia it's unlikely that a link between the effects of nicotine and schizophrenic symptoms is rigorous or robust. Nicotine and caffeine both seem to be disproportionatley favoured by certain types of uni students. I doubt there's any significant representation of schizophrenia among said population of students.

    The positive symptoms of schizophrenia are those the public is most likely to bring to mind when envisioning schizophrenics, these include auditory hallucinations and paranoid behaviour. It's these symptoms that seem to be most amenable to treatment with drugs that act on the dopamine system. The second set of the disease's symptoms are termed negative symptoms and include social isolation and degrees of depression. These secondary symptoms currently have few effective treatments. My best guess would be that nicotine and smoking, (the ritual and anachronistic, Freudian, oral pleasure) treat the secondary symptoms.

    FWIW I'm a diagnosed schizophrenic with a uni education and a plus 160 IQ. I've been diagnosed as schizophrenic, schizo-affective, and, possibly not schizophrenic at all; but my favourite diagnosis came from a neuropsychiatrist, who, upon learning that I had begun studies of epistemology at age 17, said: "People who study epistemology... (long pause)... I don't know... (head shaking)... I just don't know." My case seems to be the more interesting because I recognized my symptoms and sought medical attention, and, while suffering the full range of symptoms, was able to deal with them as symptoms of a disease and not as in any way defining who I am or considering them as causes of action. John Nash, he of "A Beautiful Mind" escaped the symptoms of his schizophrenia when he learned not to argue with his voices. The most debilitating aspect of schizophrenia is that people seem not to understand that it's a brain based disease and that the mind, as put by a neuroscientist, is just the brain doing it's job. More high functioning schizophrenics are able to get on with their lives because schizophrenia is now known to be a a disease no different than any other and the symptoms can be detected, marked, treated, minimized, and, over time, all but disregarded in day to day life.

    Electronic Cigarettes (more accurately -Personal Vaporizer or PV) simply vaporize a nicotine solution to avoid the harmful effects of smoke and its 8000 chemicals.

    Checkout Wikipedia for basic info or ecig-forum for detailed info.

    These look like normal cigarettes, have rechargeable batteries with convenient cartridges or refilling BUT it does takes a week or two to get everything right,so be careful of which model etc you choose. Ask me for advise if in doubt.

    I have a cousin diagnosed as schizophrenic. He's 33 and lives at home with no ability to maintain a simple job.

    Now, prior to being diagnosed a few years back, he self-medicated with both cigarettes and alcohol. I wonder - if nicotene is a stimulant - wouldn't a few Red Bull cans or even Ritalin do the same job? I figure I'm ADAD, and I love my caffeine. I don't really care for smoking though I can see its benefits. (It has its drawbacks also, as my two-pack/day father passed away at the early age of 67.)

  26. L-dopa /Schizophrenia/smoking by teleny · · Score: 2, Interesting
    What I'd heard (some years ago) was that cigarettes helped to soften the blow of phenothiazine-based drugs (Thorazine, Stelazine, etc.) that are commonly given to schizophrenics. These drugs work by removing L-dopa from the brain, and depressing the forebrain, thus making the subject more tractable and easy to deal with in institutional situations (the so-called chemical straitjacket, lobotomy in a pill, etc.) Marketed to doctors as "insulin for schizophrenics", they, indeed seem to work for a while: the subject becomes peaceful, and nearly unemotional, easily suggestible, and with few thoughts of their own. Higher cognition becomes more difficult: it's not unusual for someone on these drugs to go from, say, playing classical piano to watching, with interest, "Dancing with the Stars".

    However, a few months later, side effects usually begin to occur: tics and twitches, a ravenous appetite, which coupled with the disinclination to move, quickly produces extreme obesity (and ironically Type 2 diabetes), and a pernicious apathy that slowly extends itself to jobs, appearance, other people and life itself. Worse, trying to get off these drugs means that psychotic symptoms reoccur, even worse than before, as the body's L-dopa production often has increased to unnatural levels. While it's true that some patients can function, and sometimes quite well, under these circumstances, the truth is that most of them do not, and the simple equation Psychotic - (L-dopa) = Normal simply does not hold up.

    What nicotine, and to some extent, alcohol does is to increase L-dopa to a slight degree, but not as much as simply going without the drugs, and it does so fairly quickly. Part of the problem with the neuroleptics is that brain hormone production and consumption varies from moment to moment -- what would be "too much", say, waiting for a bus, would be "not enough" dancing at a lively party, brainstorming a new product, or trying to organize housework.

    Without getting all Tom Cruise on you, I don't think that they're using the right angle.
