Trigger #2: Sleepwalking to Murder Presented by: Priya Appea, Melanie Alcock, Mark Alfano, Ricksen Tam
Going to throw some raining/thunderstorm sound on here
We begin introduction
Questions We Answered How do different activities in the brain differ from a sleepwalker and a normal person? What social factors can influence individual’s sleep walking? Does stress and sleep loss affect the human physical and mental health? Is sleepwalking inherited, and how likely is it to be manifested in adults?
How do different activities in the brain differ from a sleepwalker and a normal person? sleepwalkers have “hypersychronous bursts of delta activity”
Comparing A and B- shows that in sleepwalkers (A), there is an increase in regional blood flow to the posterior cingulate cortex and to the anterior cerebellum. Comparing C and D- shows that in sleepwalkers(C) there are decreased levels of blood flow to the frontoparietal cortices.
What social factors can influence individual’s sleep walking? This disorders seems to stem from many different sources and not ONE definite cause. There are many different social factors that may increase the chances of sleepwalking. These include: - fatigue, lack of sleep - stress. ex. unemployment - substance abuse ex. alcohol or drugs - hormone changes -illness and fever
Does stress and sleep loss affect the human physical and mental health?
Loss of sleep affects younger children greatly
Impairs the mental activity of children immediately after one night of restricted sleep
Can lead to increased hunger and change in glucose tolerance
Younger children spending too much time in daycare and around many other children can lead to stress related behavioural problems.
Chronic family stress leads to increased illness in their children
Is sleepwalking inherited, and how likely is it to be manifested in adults?
Studies of twins and families suggest genetic involvement.
Subjects were able to press a switch to diminish and avoid unpleasant stimuli.
At 8 years of age, they were more likely to manifest sleepwalking, recurrent sleep talking, and emotional lability than control children
The proportion of total phenotypic variance attributed to genetic influences was 66% in men and 57% in women in childhood sleepwalking, and 80% in men and 36% in women in adult sleepwalking.
Children whose parents who experienced sleep walking episodes as children are more likely to be diagnosed with the same condition.
