3- insomnia Flashcards
Common causes of insomnia in the elderly:
- Environmental problems
- Drugs/alcohol/caffeine
- Sleep apnea
- Parasomnias: restless leg syndrome/periodic leg movements/REM sleep behavior disorder
Disturbances in the sleep-wake cycle
Psychiatric disorders, primarily depression and anxiety
Symptomatic cardiorespiratory disease (asthma/chronic obstructive pulmonary disease/congestive heart failure)
Pain or pruritus
GERD
Hyperthyroidism
Advanced sleep phase syndrome (ASPS)
how many cigarettes does one patch equal
7
Patients should be counseled to avoid caffeine and alcohol for how long before bed
4-6 hrs before bedtime
sleep apnea is common in what percent of elderly
20% to 70%
advanced sleep phase syndrome (ASPS)
excessive circadian rhythm change in elderly
sleepy by 7 pm, wake up at 4 am
alcohol and sleep
While alcohol has an immediate sleep-inducing effect, a few hours later as the alcohol levels in the blood start to fall, there is a stimulant or wake-up effect.
exercise and sleep
Regular exercise, particularly in the afternoon, can help deepen sleep. Strenuous exercise within the two hours before bedtime, however, can decrease your ability to fall asleep.
if you cant sleep for >20 min
get out of bed and go to another room; return to the bedroom when you are tired; repeat as necessary
Cognitive Behavioral Therapy for Insomnia (CBT-I)
sleep hygiene instruction, stimulus control, and sleep restriction with cognitive restructuring– effective!
examples: Sleep restriction therapy and Sleep compression therapy
Sleep restriction therapy
The patient is told to reduce his or her sleep/in-bed time to the average number of hours the patient has actually been able to sleep over the last two weeks (as opposed to the number of hours spent in bed (awake plus asleep)). As sleep efficiency increases, time allowed in bed is increased gradually by 15- to 20-minute increments approximately once every five days (if improvement is sustained) until the individual’s optimal sleep time is obtained.
Sleep compression therapy
The patient is counseled to decrease the amount of time spent in bed gradually to match total sleep time rather than making an immediate substantial change.
