Also Insomnia you have

Primary Insomnia - Insomnia as a result of external causes, IE stimulants or disruption of bodily rhythms such as shift work or jet lag.

Secondary Insomnia - Insomnia as a result of internal problems.
-Physical conditions ie arthritis
-Psychological Condiotions ie depression]
-Medication (okay so this is external but think of it as an exception as it is nessasary to cure underlying health problem)
-Stress and Anxiety

Didnt really focus on insomnia, rather narcolepsy and somnabulism but one study is Vgontas (2007) that adrenocorticotrophic Hormones cause insomnia (related to stress)



do you have some studies for primary and secondary insomnia?

By nature of sleep do you mean sleep functions or the sleep stages?


Ok, maybe I should have worded it better.

I meant Lifespan Changes in Sleep.

Thanks for the help on Insomnia. Good luck with the exam tomorrow.

Breedlove 2007-Suggested Babies need more REM sleep as it develops and organises their brain. Also said that 60 year olds spend less then half the amount of time in Slow Wave Sleep as they did when they were 20. Slow Wave Sleep in 90 year olds disappeared altogether.

Oswald 1980 - found new born babies spent 50-60% in REM, this fell to 25% for older children, 20% for adults and 10% for the elderly

Studies have shown that babies can spend up to 20 hours asleep, 11 hours in preteens, 7-8 hours in adults and 6 hours in 50+

Studies about sleep in old people are not 100pc reliable as old people tend to sleep during the day and not include that in self report questionnaires.

Thanks you too, hope it goes well:smile:
