Sleep and its disorders Flashcards
Does sleep affect a specific age group?
- no
- can affect all ages
There is rapid eye movement (REM) and non-REM sleep. Non-REM can be subdivided into 4 stages 1-4. Which of these stages are involuntary twitches common?
1 - stage 1
2 - stage 2
3 - stage 3
4 - stage 4
1 - stage 1
There is rapid eye movement (REM) and non-REM sleep. Non-REM can be subdivided into 4 stages 1-4. Which of these stages is all muscle tone lost?
1 - stage 1
2 - stage 2
3 - stage 3
4 - stage 4
2 - stage 2
- except eye movements and middle ear muscles
There is rapid eye movement (REM) and non-REM sleep. Non-REM can be subdivided into 4 stages 1-4. Stages 3-4 are our deeper sleep. Which of the following waves are common in stages 3 and 4?
1 - delta
2 - theta
3 - alpha
4 - beta
5 - gamme
1 - delta
When looking at our 1st sleep cycle, does this move from stage 1 through to REM?
- yes
- lasts around 90-120 minutes
Following the initial sleep cycle, which of the following stages do all subsequent sleep cycles go through in around 90-120 minutes?
1 - stage 1 to REM
2 - stage 2 to REM
3 - stage 3 to REM
4 - stage 4 to REM

Which gland secretes melatonin which is important in circadian rhythm and sleep?
1 - anterior pituitary gland
2 - posterior pituitary gland
3 - pineal gland
4 - parathyroid gland
3 - pineal gland
Which key nucleus in the brain is responsible for governing the circadian rhythm?
1 - thalamic nucleus
2 - basal ganglia nucleus
3 - sensory nuclei
4 - suprachiasmatic nucleus
4 - suprachiasmatic nucleus
- part of hypthalamus
Are we able to modulate our circadian rhythm?
- yes
- can use photic inputs and non-photic inputs
Do older or younger people sleep more?
- younger people
- REM decreases 0.6%/decade
Is sleeping useful for consolidating memories?
- yes
Sleeping is important for consolidating memories. Which part of the brain does this primarily occur in?
1 - basal ganglia
2 - hippocampus
3 - thalamus
4 - suprachiasmatic nucleus
2 - hippocampus
From a brains perspective, which of the following are benefits of sleeping?
1 - Learning and memory consolidation o
2 - Synaptic modification in the hippocampus linked with memory
3 - Restorative functions such as glucose and proteins for healing
4 - Neural detoxification (glymphatics clearance)
5 - all of the above
5 - all of the above
Which of the following is used to describe when someone doesn’t get sufficient sleep?
1 - Insomnia
2 - Hypersomnia
3 - Parasomnias
4 - Circadian rhythm disorders
1 - Insomnia
- classed as a symptom rather than a disorder
- this is NOT a diagnosis
- clinically significant in 10% of people
Which of the following is NOT typically affected by insomnia?
1 - Women
2 - Shift workers
3 - Young children
4 - Medical and psychiatric comorbidity
3 - Young children
What is short term/acute insomnia?
1 - <4 weeks
2 - <3 months
3 - <6 months
4 - <12 months
2 - <3 months
- insomnia typically gets worse if untreated
What is long term/chronic insomnia?
1 - >4 weeks
2 - >3 months
3 - >6 months
4 - >12 months
2 - >3 months
- insomnia typically gets worse if untreated
When managing insomnia, which of the following is NOT typically performed?
1 - Identify the cause
2 - Treat any underlying cause e.g. depression, anxiety, pain
3 - Explain clearly what is happening and why
4 - Ensure good sleep hygiene (psychoeducation or CBT)
5 - Advise the person not to drive if they feel sleepy
6 - prescribe sleeping medication
7 - In certain sleep disorders, the DVLA must be informed (sleep apnea)
6 - prescribe sleeping medication
- this would only be prescribed if the insomnia is though to be short lived, like loss of a loved one
- benzodiazepines or non-benzodiazepines
For long term insomnia, CBT is the 1st line treatment. But what other medication can be offered if there is an acute exacerbation in patients aged >55 y/o?
1 - cortisol
2 - benzodiazepines
3 - melatonin
4 - all of the above
3 - melatonin
When talking about psychoeducation, we can talk about preparing for bed, including:
- bed time routine
- milky drink (contains tryptophan)
- keep lights low
We should also aim to wind down, but what is the minimum time advised to wind down?
1 - >30 minutes
2 - >1 hour
3 - >2 hours
4 - >6 hours
2 - >1 hour
- tryptophan is a precursor for serotonin and effects melatonin synthesis
If medications are to be prescribed to a patient with insomnia, typically how long should they be prescribed for?
1 - <72h
2 - <1 week
3 - <2 weeks
4 - <6 weeks
2 - <1 week
Which 2 of the following medications are used most commonly in patients with insomnia?
1 - zopiclone
2 - diazepam
3 - zolpidem
4 - flumazenil
1 - zopiclone
3 - zolpidem
- need to be careful with benzodiazepines or non-benzodiazepines as these can lead to rebound insomnia
Which of the following is used to describe when someone gets too much sleep?
1 - Insomnia
2 - Hypersomnia
3 - Parasomnias
4 - Circadian rhythm disorders
2 - Hypersomnia
Which of the following are associated with causing hyper insomnia?
1 - psychiatric conditions (depression)
2 - medications
3 - sleep/breathing disorders
4 - central causes (narcolepsy)
5 - general medical conditions (hypothyroidism)
6 - all of the above
6 - all of the above
