The PURPLE period describes a time in infancy which is stressful for parents due to the infants crying. What does the PURPLE stand for?

P - Peak of Crying. Baby cries more each week. Cries most at 2 months and then decreases at 3-4 months

U - Unexpected. Crying can come and go and you don't know why.

R - Resists soothing. Your baby may not stop crying no matter what you try.

P - Pain-like face. Baby may look like they are in pain, even when they are not.

L - Long lasting. Can last up to 5 hours per day, sometimes more.

E - Evening. Your baby may cry more in the late afternoon and evening.


What is the normal developmental task of the "terrible two's"? (Toddler period)

Develop autonomy and independence.


What are the main developmental tasks in the preschool period (3-5 years)?

Language, cognitive ability and social-emotional skills.


What is narcolepsy?

Clinical syndrome of excessive daytime sleepiness with cataplexy, hypnagogic hallucinations, and sleep paralysis.


What is insomnia of childhood?

Repeated difficulty initiating and/or maintaining sleep that occurs despite age-appropriate time and opportunity for sleep.


One of the most common sleep disorders found in infants and toddlers is behavioural insomnia of childhood, sleep onset association type. Why do children develop this disorder?

The child learns to fall asleep only under certain conditions or associations which typically require parental presence, ie. being rocked or fed, and does not develop the ability to self soothe.

During the night, the pt then wakes as part of normal sleep cycle (brief arousal at end of 60-90 min cycle) and is not able to go back to sleep without the same conditions being present.


Behavioural insomnia of childhood, limit setting type is a type of sleep disturbance more common in preschool aged and older children. How does this disorder develop and what type of behaviours do the children display?

Often the result of parental difficulties in limit setting, and managing behaviour. Includes the unwillingness to set consistent bedtime rules and enforce a regular bedtime routine. May be exacerbated by the childs oppositional behaviour.

Typical behaviours include stalling and refusing to go to bed.


What is psychophysiologic or primary insomnia?

AKA "learned insomnia". Insomnia that is not primarily a result of parent behaviour, another sleep disturbance or a psychiatric illness.

Usually occurs in adolescents and is characterised by learned sleep preventing associtions and heightened physiologic arousal resulting in sleeplessness and decreased daytime functioning.

A hallmark is excssive worry about sleep and an exaggerated concern of the potential daytime consequences.


What is the BEARS screening tool?

A screening tool assessing the five major sleep disorders affecting children aged 2-18 years.

B - Bedtime problems

E - Excessive daytime sleepiness

A - Awakenings during the night

R - Regularity and duration of sleep

S - Snoring


Sleepwalking, sleep terrors and confusional arousals are all partial arousal parasomnias which are more common in preschool and school aged children because of the relatively higher percentage of slow wave sleep in younger children.

What are the clinical manifestations of the partial arousal parasomnias?

  • Usually amnesia for the events.
  • Occurs at transition out of "deep" or SWS so has clinical features of awake (ambulation, vocalizations) and sleeping (high arousal threshold, unresponsiveness to the environment) states.
  • Typically during first few hours of sleep
  • Few minutes to an hour
  • Sleep terrors are sudden in onset with high degree of autonomic arousal (tachycardia, dilated pupils).
  • Attempts at comforting or waking results in increased agitation. Pt also avoids comforting and waking.


According to Erikson's, what psychosocial crises occur at ages:

  1. 0-2 years
  2. 2-4 years
  3. 4-5 years
  4. 5-12 years
  5. 13-19 years

  1. Basic trust vs mistrust
  2. Autonomy vs shame and doubt
  3. Initiative vs guilt
  4. Industry vs inferiority
  5. Identity vs role confusion


What are some impaired social skills demonstrated by a child with ASD?

  1. Non-verbal behaviours eg eye contact, body posture
  2. Failure to develop peer relationships
  3. Lack of social and emotional sharing


What are some impairments in verbal and non verbal communication demonstrated by a child wtih ASD?

  1. Delay in development of spoken language
  2. No attempt to communicate by other means
  3. Inability to initate conversation
  4. Stereotyped and repetitive language, lack of imaginative play


What are some of the repetitive and stereotype patterns of behaviour demonstrated by a child with ASD?

  1. Adherence to routines
  2. Lack of imaginative play and behaviour
  3. Restrictive patterns of interest
  4. Preoccupation with parts of objects
  5. Repetitive motor mannerisms eg. hand flapping, door closing


Cataplexy is pathognomonic for narcolepsy. The prevalenceo of narcolepsy with cataplexy is 0.2-0.5/10,000 (cf 3-16 per 10,000 of narcolepsy without cataplexy). What is cataplexy?

  • An abrupt, bilateral, partial or complete loss of muscle tone, classically triggered by an intense positive emotion (eg. laughter, surprise).
  • Typically brief - seconds to minutes
  • Fully reversible with complete recovery to normal tone when episode ends.
  • Rarely the first symptom of narcolepsy but often presents within 12 months of EDS (Excessive Daytime Sleepiness).


What is the treatment for narcolepsy?

Non Pharmacologic

  • Avoid drugs that can produce daytime sleepiness or insomnia.
  • Napping/sleep hygeine - one to two 20 minute naps will often improve sleepiness for 1-3 hours. Sleep deprivation may worsen symptoms so pts should maintain regular and adequate sleep schedule.
  • Psychosocial support


  • Modafinil - non-amphetamine "wakefullness promoting agent". MOA not well understood but may increase dopaminergic signalling.
  • Methylphenidate - CNS stimulant and potent wakefullness promoting drug. Second line agent due to sympathomimetic side effects.
  • Amphetamines - CNS stimulants and most potent wakefulness promoting drugs. Also second line agent due to sympathomimetic side effects. Can also improve cataplexy, hypnagogic hallucinations and sleep paralysis.


What is enuresis? 

Repeated voiding of urine into clothes or bed at least twice a week for at least 3 consecutive months in a child who is at least 5 yr of age, not caused by medications or a medical condition.

Diurnal enuresis defines wetting while awake and nocturnal enuresis refers to voiding during sleep.
