Trouble Concentrating? A Patch on the Arm Could Help

"I think the Wilens' study is a good study, although further work is
needed," Edward D. Levin, PhD, of Duke University Medical Center in Durham,
N.C., tells WebMD. "Our findings are quite similar. We've done a few
studies looking at the effects of the nicotine skin patch on attentiveness in
adults with ADHD, schizophrenia, and Alzheimer's patients and found significant
improvement in attentional performance in all those groups."
Levin says that nicotine stimulates the release of dopamine, which may mean
that nicotine's effects may be similar to that of Ritalin or amphetamine, which
has also been used to treat ADHD. Dopamine is a chemical in the brain that is
responsible for aiding in the transmission of nerve impulses and has been
identified as one of the important chemicals in ADHD. Evidence suggesting a
role for nicotine in ADHD comes from studies which show that the smoking rate
for adults with ADHD is double that seen in the general population and that
people with ADHD smoke at an early age. "They may be smoking to
self-medicate their symptoms of inattentiveness," says Levin.
"In no way am I recommending that any one take up or keep smoking. ...
Actually, providing some nicotinic therapy might help prevent these people from
taking up smoking for self-medication," Levin tells WebMD. "Nicotine
has gotten a bad name in terms of being the drug in tobacco which underlies
tobacco addiction. Nicotine itself or some of these nicotinic agonists hold
great promise for therapeutics."

- For adults who suffer from moderate ADHD, the nicotine patch could be an
alternative treatment to Ritalin or antidepressants.
- The nicotine patch will not ever replace these other drug options, but
further study is needed to determine who could benefit and what the dosage
- The rate of smoking among people with ADHD is double that of the general
population, leading one researcher to suggest they may be attempting to
