While there are a number of factors that can contribute to sleepwalking, the first thing that should be noted is that it appears to be genetic, as relatives of sleepwalkers are far more likely than other people to be sleepwalkers themselves. That said, the exact cause of sleepwalking is not known. But sleepwalking seems to be triggered by many stimuli. One is stress, either psychological or physical (as in fevers and other ailments.) Another is the use of drugs and alcohol before sleeping. These can include sleep-inducing drugs and sleep aids, as well as other drugs like anti-allergy medications. People undergoing major hormonal changes are taking place (teenagers, pregnant and menopausal women) seem to be especially prone to sleewalking, in addition to other sleep disorders.
