Research during the past decade has revealed that nicotine is an especially addictive substance for people with schizophrenia and bipolar disorder. However given the overall harm of tobacco use this should never be a basis for discouraging patients from its cessation or. Approximately 85 of people who have schizophrenia are also heavy cigarette smokers and 60 to 70 of people with bipolar disorder and they smoke two to three times as much as an average smoker.

For years researchers have noted an unusual association between smoking and schizophrenia. With acute nicotine challenge in abstinent or never-smokers significant improvements are observed implying that nicotine really improves cognition in schizophrenia and it is not merely restoration of deficits caused by nicotine deprivation Harris et al 2004. 3 Nicotine goes straight into the lungs and is rapidly absorbed by the oxygenated blood that the heart pumps throughout the body and brain.

A second explanation for the association between schizophrenia and smoking is that smoking acts as an aetiological risk factor for schizophrenia. One study found that administering a nicotine patch to smokers with schizophrenia after a period of nicotine withdrawal improved their performance on selective attention tasks. There is no consistent evidence of favorable effects of nicotine on symptoms in schizophrenia but the evidence of detrimental effects of smoking on general health is highly consistent.

Schizophrenia is a severe and disabling mental condition that affects more than 21 million. Given the high frequency of smoking in schizophrenic patients clinicians need to check smoking status in each patient. Prior to smoking cessation implementation it is crucial to understand on the ways and reasons for schizophrenia patients to consume nicotine for self-medicate symptoms which may lead to the development of new treatments for schizophrenia and nicotine dependence.

Neurobiological and psychosocial factors reinforce the high use of nicotine by patients with schizophrenia. In fact it has opened up new channels for a non-addictive nicotine based treatments for people not only with schizophrenia but with other disorders linked to decreased activity of the prefrontal cortex like ADHD PTSD and bipolar disorder. There is a discrepancy in the literature with numerous animal studies suggesting that nicotine should help negative symptoms but scarce clinical data suggesting that this may be true in those with schizophrenia.

4647 It is postulated that nicotine compensates a hypodopaminergic state in prefrontal brain regions thought to underlie the negative symptoms and cognitive deficits seen in schizophrenia. Nicotine has been shown to improve cognitive deficits in individuals with psychosis including working memory and attention 42 45 and in this context nAChRs have emerged as targets for the treatment of cognitive and negative symptoms. Nicotine dependence and schizophrenia share genetic liability.

Scientists have found that smoking and schizophrenia are tightly linked but are not sure why. In these analyses we calculated genetic risk scores for schizophrenia supplementary. Increased rates of smoking are relatively specific to schizophrenia and are not as frequently and as extensively observed in other.

This clearly established that nicotine in fact can help people with Schizophrenia. It may be that repeated activation by nicotine of the mesolimbic system over a long time precipitates the onset of schizophrenia in vulnerable individuals. Conversely upon smoking cessation smokers may require a reduction in the dosage of antipsychotics.

Research indicates that nicotine may improve cognitive and sensory deficits of schizophrenia by increasing deficient levels of the chemical dopamine in areas of the brain like the nucleus accumbens and prefrontal cortex. Schizophrenic patients who smoke may require higher dosages of antipsychotics than nonsmokers.
