- Sleepwalking

- Sleepwalking refers to activities occurring unconsciously when someone is asleep that normally happens when awake.
- Sleepwalkers are usually unaware of their activities and engage in automatic behaviours, it usually occurs in stage 3 or 4
- It often occurs during childhood but the cause is unknown.
- Incomplete arousal
- A person who is sleepwalking is partily awake in a sense they are taking place in activities a person would do when in a woken state, but they are asleep.
- They are in a deep sleep which makes it difficult to rouse the sleepwalker.

- Risk Factors
- Factors such as sleep deprivation and stress seems likely to increase sleepwalking.

- There is evidence that sleepwalking is inherited. Broughton found that the prevalence of sleepwalking in first degree relatives.
- Twin studies have also been used, a researcher reported that about 50% concordance rate in MZ twins compared to 10-15% om DZ twins. This shows that there is a tendency for sleepwalking to be inherited through genes.
- Evidence for sleepwalking may be found from the diathesis model. The model suggest that genes merely provide a vulnerability for sleepwalking, but will only occur in situations of environmental stress.
- Zarda studied patients who had suspected sleepwalking, and were prevented from falling to sleep. On the first night, patients showed 50% signs of sleepwalking and 90% on the second night.
- This suggests that sleep deprivation does not lead to sleepwalking in normal people thus, sleep-deprivation was acting as a stressor in people who had a vulnerability for sleepwalking.
