INSOMNIA
โ€ข Outline :
โ€ข Definition
โ€ข Type
โ€ข Assessment
โ€ข Nonpaharmacological Rx
โ€ข Pharmacological Rx
insomnia :
difficulty falling asleep, staying asleep, or early awakening despite
the opportunity for sleep that is associated with impaired daytime
functioning and occurs at least 3/wk for at least one month.
โ€ข Insomnia can be:
๏‚ง acute (lasting up to 3 month )
๏‚ง chronic (lasting >3 month )
๏ถInsomnia (without comorbidity)
๏ถ Insomnia with comorbidity:
โ€ข o Medical disorders
โ€ข o Psychiatric disorders
๏ถInsomnia with another primary sleep disorder
โ€ข Chronic insomnia consequences :
๏‚ง cognitive difficulties (e.g., problems with memory, attention, and
concentration; confusion),
๏‚ง anxiety and depression,
๏‚ง poor quality of life,
๏‚ง risk of suicide,
๏‚ง substance use relapse,
๏‚ง possible immune dysfunction,
๏‚ง increased risk of CVD (e.g., HTN, MI, or DM ) and all-cause
mortality.
โ€ข Excessive daytime sleepiness caused by insomnia can
lead:
๏‚ง to diminished work performance,
๏‚ง increased absenteeism,
๏‚ง MVC , accidents at work, fewer promotions,
๏‚ง increased accidents and falls in older persons,
ASSESSMENT
โ€ข clinical diagnosis;
โ€ข medical and
psychological Hx.
ASSESSMENT
โ€ข Detailed sleep Hx
โ€ข screen for sleep apnea.
โ€ข screen for depression/anxiety disorder (GAD-7/PHQ-9)
โ€ข CONSIDER screening for other mental health conditions
if relevant (Bipolar/ADHD).
โ€ข CONSIDER screening for other medical issues such as
pain syndromes, and disease states in all other systems
that can disrupt sleep.
โ€ข Ask the patient to keep a sleep diary
MANAGEMENT
โ€ข The ultimate treatment goals:
โ€ข qualitatively and quantitatively improve sleep
โ€ข decrease related distress.
โ€ข improve daytime functioning
NON- PHARMACOLOGICAL RX
โ€ข Behavioral interventions are effective and recommended
as an initial approach to the treatment of chronic
insomnia based on RCT .
โ€ข Sleep hygiene
โ€ข Stimulus control therapy
โ€ข Sleep restriction therapy
โ€ข CBT
SLEEP HYGIENE
โ€ข exercise regularly (not within 4hrs of bedtime);
โ€ข avoid large meals and limit fluid intake in the evenings;
โ€ข limit caffeine, tobacco, and alcohol intake 4-6 hrs before
before bedtime.
โ€ข use the bedroom for sleep .
โ€ข maintain a regular sleep-wake cycle without daytime
napping.
โ€ข avoid negative stimuli at bedtime:
โ€ข loud noises,
โ€ข bright lights.
โ€ข extreme temperature variations.
STIMULUS CONTROL THERAPY
โ€ข Lie down to sleep only when feeling sleepy
โ€ข Avoid wakeful activities at bedtime (e.g., watching
television, talking on the phone, eating)
โ€ข Leave the bed if unable to fall asleep within 20 minutes
and return when sleepy
โ€ข Maintain a consistent sleep-wake cycle(temporal control
therapy ) :
set the alarm for the same time each morning regardless of how
much sleep occurs during the night.
SLEEP RESTRICTION THERAPY
โ€ข Limit time in bed to the number of hours actually spent
sleeping (not less than five hours); sleep time gradually
increases as sleep efficiency improves.
โ€ข There is a risk of excessive daytime sleepiness with this
approach.
CBT
โ€ข CBT-I significantly improves chronic insomnia
and daytime functioning for 2 years.
โ€ข is a combination of cognitive therapy,stimulus control
therapy, and sleep restriction therapy with or without the
incorporation of relaxation therapy.
HYPNOTICS
โ€ข There is good evidence for the efficacy of hypnotic drugs
in short-term insomnia but they do not treat any
underlying cause.
โ€ข adverse effects, :
โ€ข daytime sedation
โ€ข poor motor concentration
โ€ข cognitive impairment.
โ€ข In older people, in particular, the magnitude of the
beneficial effect of hypnotics may not justify the
increased risk of adverse effects (ie, falls and cognitive
impairment).
โ€ข Hypnotics should be prescribed at the lowest effective
dose for as short a period as possible.
โ€ข In transient insomnia:1-2doses of a short-
acting hypnotic
โ€ข Short term insomnia :intermittent dosing of a
short acting hypnotic given for no more than 3 weeks.
โ€ข Chronic insomnia :
โ€ข rarely benefits from the routine use of hypnotics
โ€ข should where possible be avoided.
โ€ข licensed hypnotic drugs :
โ€ข benzodiazepines (temazepam) .
โ€ข Z-drugs (zopiclone, zolpidem and zaleplon).
โ€ข NICE recommends that switching hypnotics should only
occur if there are documented adverse effects from a
particular agent.
BENZODIAZEPINES
โ€ข Effective
โ€ข many people develop tolerance ,
โ€ข Less therapeutic benefit from chronic use,
โ€ข dependence after 2-4 weeks of regular use.
โ€ข A withdrawal symptoms
โ€ข Rebound insomnia which is worse than the
original symptoms.
โ€ข Risk of misuse,
โ€ข only for severe, disabling insomnia
โ€ข The lowest dose for <4wks
THE โ€˜Z DRUGSโ€™
โ€ข Zaleplon, zolpidem and zopiclone (the Z-drugs) are
nonbenzodiazepine hypnotics.
โ€ข Although the Z-drugs differ structurally from the
benzodiazepines, they are also agonists of the GABA
receptor complex and therefore enhanceGABA-mediated
neuronal inhibition.
โ€ข developed with the aim of overcoming some of the
disadvantages of benzodiazepines
โ€ข Promethazine25-50 mg : is an alternative for
patients in whom other hypnotics are not recommended.
โ€ข It has a long half-life and there is the potential for hang
over effect.
TAKE HOME
โ€ข CBT-I is the cornerstone of treatment for insomnia.
When CBT-I is combined with medication it may produce
faster improvements in sleep than CBT-I alone. If
combining CBT-I and medication, after the initial phase,
it is best to continue CBT-I while tapering/discontinuing
medication.
ACUTE INSOMNIA
โ€ข Treat acute insomnia only if there is a substantial
negative impact on daytime performance.
โ€ข Intervene early and suggest behavioral therapy .
โ€ข Consider using short term (e.g., two weeks)
pharmacotherapy with close follow-up based on the
severity and urgency of the presentation.
โ€ข Start medication at same time as CBT-I.
โ€ข Follow-up to monitor progress in two to four weeks.
