Week 5 Flashcards
(24 cards)
What is normal sleep?
Regulation of both the Homeotstatic and Circadian cycles.
Describe what is ment by the Homeostatic model of sleep (Sleep drives sleep mode)
This means that with every hour you are awake the drive to sleep inceases
Descibe what is meant Circadian alterness, how does it differ from homeotsasis
Circadian signal increases in the morning and levels out and decreases when we sleep. unlike homoestasis which ises throughout the day and falls duing sleep, circadian peaks between 6 and 9pm
What are some chnages in sleep that occur as we age
there are more wakeful peiods and less rem sleep
Who is most likely to insomnia. Hannah a 60 year old femal, Larry a 72 year old male, Hayley a 22 year old female, or Ryan and 19 year old boy explain why.
Hannah age 60 followed by Larry ages 72 then Hayley at 22 and finally Ryan.
Females have higher rates of insomnia, as do older people.
how is insomina diagnosed
complaint of inabiity to sleep distress cant sleep 3 times a week for 3 weeks cant sleep despite adequate oppertunity disturbance is not due to something else
describe psychophysioogical insomnia
heightened levels of arousal lead to an inability to wind down and generate sleep this leads people to conclude they cant sleep which also prevents them sleeping
what is sleep state misperception
a perceived inability to sleep: sleep is monitered and looks fine but in the morning the person will report poor sleep
describe idiopathic insomnia
develops in childhood and lasts a long time, there are issues in initiating and maintaining sleep but there is not real cause i.e. not hyperarousal etc.
describe Inadequate sleep hygiene
insomnia due to sleeping a non-regular time leading to a sort of jet lag and lack or rituals or unhealthy rituals (using phone) before bed
describe Adjustment Sleep disorder
someone who is struggling to sleep in response to a stressor e.g. life anxiety or PTSD
describe Behavioural insomnia of childhood
children who develop poor sleeping habits e.g. refusing to go to bed. Or not sleeping in own bed/needing music or a show to listen to. When the music is no longer there, or they have to sleep in there own bed they develop insomnia like symptoms.
what is narcolepsy
recurrent periods of an irrepressible need to sleep or lapsing into sleep
how is narcolepsy diagnosed
Occurring three times a week for at least 3 months
an episodes of cataplexy (loss of muscle tone) , hypocretin (chemical signal used to stay awake) deficiency and or REM sleep within 15 minutes of sleeping a short sleep latency (fall asleep quickly)
what is Circadian Rhythm Disorder
A persistent or recurrent pattern if sleep disruption primarily due to an alteration of the circadian system and the sleep wake schedule required
- This may lead to excessive sleepiness or insomnia of both
what is Shift work sleeping disorder
out of time circadian rhythm due to having to work through the night
what is Irregular sleep-wake pattern
insomnia at night and sleepiness during the day with fragmented sleep
contast Delayed sleep vs advanced sleep phase syndrome
delayed = sleep late wake late advanced = sleep early wake early
what is Non-24hr sleep wake disorder
there is no rhythm of sleep and wake (50% blind individuals).
what is the Chronotherapeutic approach to treatment of sleep disorders
Shifting the circadian rhythm using light and melatonin.
Someone with an advance should have bright light leading to sleep and melatonin in the morning with someone with a delay should have melatonin in the afternoon and bright light in the morning
what are parasomnias
unusual sleep acts such as night terrors and sleep paralysis
what are disorders of non rem sleep and what are there characteristics
sleep walking and sleep terror. amnesia episodes
what is nightmare disorder
a disorder of rem sleep, repeated dreams making the individual awake and alert
what is rapid eye movement sleep behaviour disorder
complex or violent behaviours while sleeping (most common in middle aged or older people_
