Nicotine and Schizophrenia
There is a new study out that links improved cognitive functioning with nasal nicotine spray use by people who have schizophrenia. Smoking is not recommended for anyone, however, because it causes cancer.
The study reports:
"Schizophrenics have among the highest rates of cigarette smoking. Some studies indicate that cigarette smoking or nicotine may ameliorate some of the cognitive or theoretically related neurophysiological deficits seen in schizophrenic patients.
This study investigated the effects of nicotine nasal spray on measures of attention, verbal memory, and visual-spatial memory in schizophrenic patients who were chronic smokers, using a double-blind placebo-controlled pre-post experimental design. Compared to placebo, active nicotine spray significantly decreased reaction time on the Conner's CPT and improved scores on a measure purported to reflect spatial working memory on a dot task.
There were trends for the increased number of hits and decreased number of errors in pre-post comparisons on the CPT task in the active nicotine session. There were no effects of active nicotine nasal spray on verbal memory. Our results suggest that nicotine may modestly enhance attention and spatial working memory in schizophrenic patients who are cigarette smokers and have been abstinent overnight."

More Information on Schizophrenia Coping
i have been diagnosed with schizophrenia since 1995 and quit smoking since 1992. In 2005 i started occasionally using nicotine chewing gum while working. I use it only when i have trouble concentrating and continuing working since i am afraid of abusing it. It works great for cognition or concentration. It's the only thing that really helps me with my work.
since i read about the problems with nicotine i am really looking forward to the many nicotinic drugs in the pipeline.

To the Mom with the schizo son:
Recommend your son to use Swedish snus or chewing tobacco instead of cigarettes to reduce the cancer risk.
