- Sleep Disorders: Sleep walking
- Common in childhood. Affecting 20% of children.
- Sleep walking only occurs during SWS.
- Not conscious and have no memory of what happened whilst sleep walking.
- Incomplete arousal
- EEG recordings made during sleep walking show a mixture of delta waves (typical of SWS) and beta waves which are characteristic of the awake state.
- Likely that sleep walking occurs when a person is woken up but the arousal of the brain is incomplete.
- Various factors
- These increase the likelihood of sleep walking
- These various factors include: sleep deprivation, alcohol, and stress.
- Hormonal changes in women during menstruation can also trigger sleep walking.
- Why children?
- may happen because children have more SWS than adults.
- Oliviero suggested that the system that normally inhibits motor activity in SWS is not sufficiently developed in children.
- Was demonstrated in a study where they found the sleep walkers showed signs of immaturity in the relevant neural circuits.
- Oliviero suggested that the system that normally inhibits motor activity in SWS is not sufficiently developed in children.
- There is strong evidence to to suggest that Sleep Walking has a genetic basis.
- Broughton found that the prevalence of SW in first degree relatives of an affected subject is at least 10 times greater than in the general population.
- This shows that Sleep Walking may have a genetic link.
- Broughton found that the prevalence of SW in first degree relatives of an affected subject is at least 10 times greater than in the general population.
