Sleep Needs Vary by Age

• Infants:– 16-18 hours of total sleep time (TST) daily– Begin nocturnal sleep with rapid eye movement

(REM) cycle

• Age 1: – ↓ to 14 hours of total daily sleep– Begins “adult pattern” of alternating nonREM to REM

cycles

Page 4: Insomnia: Special Considerations for Specific Populations of Women Kin M. Yuen, MD, MS FAASM, D, ABSM Medical Director Bay Sleep Clinic, CA

Adolescence

• Slow-wave sleep (SWS) begins to decline• Tendency toward later time to bed and time

to rise: – Delayed sleep phase syndrome

Page 5: Insomnia: Special Considerations for Specific Populations of Women Kin M. Yuen, MD, MS FAASM, D, ABSM Medical Director Bay Sleep Clinic, CA

Normal Sleep for Healthy Adults

• Average total nocturnal sleep time is 7.5-8 hours• Sleep latency: 10-15 minutes• Sleep stages of TST

– 5% stage 1– 50% stage 2– 15%-25% stages 3 and 4 SWS– 20%-25% REM

Aging

• More lighter stages of sleep (stage 1)• Less SWS

– Women with more preserved SWS objectively• Age 60->70 years

– Men 6-7% TST

– Women 17% TST

– Women with more subjective complaints

Insomnia is Highly Prevalent

• Chronic insomnia is estimated to affect 10% (range 9%-24%) of the population1

• 30% to 50% of the general population are estimated to have insomnia of any duration or severity

• “The prevalence of insomnia symptoms generally increases with age, while the rates of sleep dissatisfaction and diagnoses have little variation with age”2

National Sleep Foundation 2003 Poll

• One or more symptoms of a sleep problem– Age 55-64: 71%– Age 65-74: 65%– Age 75-84: 64%

• Insomnia with more than 1 symptom– Women: 50%– Men: 45%

• 22% age 55-64 and 46% age 75-84 nap 1-3 times/week

Menstrual Cycle

• Early in the cycle: more airway resistance– Pain/discomfort disturbed sleep

• Later cycle– Excessive daytime sleepiness– Insomnia: trouble falling asleep, staying asleep,

nonrefreshing sleep

Page 10: Insomnia: Special Considerations for Specific Populations of Women Kin M. Yuen, MD, MS FAASM, D, ABSM Medical Director Bay Sleep Clinic, CA

Hormonal Effects on Sleep

• Inconsistent reported effects on SWS• Estrogen

Turnover of norepinephrine in brain

Variable effects on REM sleep

Page 11: Insomnia: Special Considerations for Specific Populations of Women Kin M. Yuen, MD, MS FAASM, D, ABSM Medical Director Bay Sleep Clinic, CA

Hormonal Effects

• Estrogen– Variable effect on REM1

• Progesterone– Sedating2

– Increases NREM2

– Lack/withdrawal: difficulty falling asleep2

Page 12: Insomnia: Special Considerations for Specific Populations of Women Kin M. Yuen, MD, MS FAASM, D, ABSM Medical Director Bay Sleep Clinic, CA

Estrogen and Sleep

• Humans: REM sleep cycles1

– REM sleep latency?1

– Number of spontaneous arousals1

• Postestrogen replacement– Sleep onset latency (SOL)2

– Wake after sleep onset (WASO)– TST– REM2 and SWS3

Hormonal Effects on Sleep

• Progesterone• NREM sleep1

– Exogenous:• Benzodiazepine-like sedation in men and women1

• Active metabolites: Pregnanolone1

• α-aminobutyric acid (GABA) receptor1 • Dose-dependent sleep onset (SO), WASO

– May sleep spindle frequency

Sleep and the Menstrual Cycle

• SO and maintenance insomnia• Overall: subjective sleep complaints late

luteal phase SOL Wake after SO ↓ Sleep efficiency

Page 15: Insomnia: Special Considerations for Specific Populations of Women Kin M. Yuen, MD, MS FAASM, D, ABSM Medical Director Bay Sleep Clinic, CA

Menstrual-related Sleep Disorder

• Changes in sleep architecture: – SWS– REM– SO latency – Wakefulness after SO– Sleep efficiency

Page 16: Insomnia: Special Considerations for Specific Populations of Women Kin M. Yuen, MD, MS FAASM, D, ABSM Medical Director Bay Sleep Clinic, CA

Sleep and Pregnancy

• Subjective complaints– Excessive daytime sleepiness1

– Many hormones responsible Progesterone, β-human chorionic gonadotropin,

prolactin, luteinizing hormone– Fatigue, body temperature– Shortness of breath

Pregnancy: Periodic Limb Movement, Restless Leg Syndrome • May be associated with:

– Fe deficiency anemia – Type-2 diabetes – Uremia– Symptoms usually subside postpartum

• 15%-25%1,2 women develop restless leg syndrome in third trimester– Conservative treatment before third trimester–

avoid caffeine

Postpartum Sleep

• 30% new mothers report disturbed sleep• Sleep efficiency in first 2-4 weeks <third

trimester • Average 2 hours time of wakefulness (WASO)• First-time mothers’ sleep most disturbed• Some rebound of stage 4, but REM• Women with premature infants have TST,

WASO• Alterations in melatonin, cortisol

Postpartum Depression and Sleep

• Nighttime labor (↑oxytocin) and sleep disruptions (third trimester) associated with depressed mood after childbirth

• REM latencies associated with depressed mood• Likely multifactorial; heightened reaction to stress

Page 23: Insomnia: Special Considerations for Specific Populations of Women Kin M. Yuen, MD, MS FAASM, D, ABSM Medical Director Bay Sleep Clinic, CA

Postpartum Depression

• Baby blues– Very common: 50%-80% of all new mothers– 2 weeks after delivery: about Day 3 to Day 5

• Postpartum depression– 10%-20% of new mothers– May last up to 1 year– Major depression symptoms– 50% with past history of depression– Insomnia to overwhelming fatigue– Negative feelings toward baby, resentment

• Postpartum psychosis– Rare: 0.1% of new mothers– 3 weeks after delivery– Past history of bipolar disorder

• Third trimester– Fragmented sleep

Page 26: Insomnia: Special Considerations for Specific Populations of Women Kin M. Yuen, MD, MS FAASM, D, ABSM Medical Director Bay Sleep Clinic, CA

Pregnancy Summary 2

• General decrease in parasomnia• Beware of new onset snoring before

second trimester; correlation with preeclampsia• Restless legs movement more common in

third trimester• Postpartum depression in 10%-20% of

new mothers– Antidepressants (eg, selective serotonin reuptake

inhibitors [SSRIs] may be justified)

Narcolepsy1,2

• Disability/early maternity leave• Letter to employer to allow naps• Avoid medications during first trimester and

when nursing• If benefit outweighs risks:

– Cataplexy: GHB/SSRIs – Insomnia: GHB or zolpidem – Excessive daytimes sleepiness: weaker

stimulants/modafinil – Pregnancy test before initiating medications?

Insomnia Is More Prevalent In Women1,2

• Various studies have identified female gender as a strong risk factor for insomnia

• Overall, women are about 1.4 times more likely to report insomnia than men

• Heightened psychiatric morbidity and different impact of sex steroids may play an important role

Insomnia and Comorbid Conditions:An Important Factor During Menopause?

• Insomnia is highly prevalent among patients with other medical and psychiatric illnesses and may:– Worsen clinical outcomes and impact

quality-of-life (QoL)1

– Predispose patients to recurrence2

– Persist despite treatment of the primary condition3

– What happens during the menopausal transition?

Window of Vulnerability1-3

• Heightened prevalence of mood and sleep disturbances during periods of intense hormone variability/fluctuation

• Adverse outcomes resulting from the disruption of hormone milieu

Window of Opportunity1,2

• A stable hormone milieu or hormone interventions may exert a prophylactic (eg, neuroprotective) effect

• Hormone intervention/modulation may exert a therapeutic effect

Page 39: Insomnia: Special Considerations for Specific Populations of Women Kin M. Yuen, MD, MS FAASM, D, ABSM Medical Director Bay Sleep Clinic, CA

Sleep and Menopause

• Peri- and postmenopausal women have more sleep complaints than younger women1

• 41% of early perimenopausal women report sleep difficulties2; many are at higher risk for developing depressive symptoms

• Frequent awakenings• Difficulty falling back to sleep• Difficulty falling asleep

Page 40: Insomnia: Special Considerations for Specific Populations of Women Kin M. Yuen, MD, MS FAASM, D, ABSM Medical Director Bay Sleep Clinic, CA

Sleep and Menopause (cont’d)

• Frequent awakenings suggest insomnia is secondary to vasomotor symptoms1

• More common in women with surgical menopause

• However, waking episodes may occur in absence of hot flashes2,3

Sleep-disordered Breathing in Menopause

• The prevalence of obstructive sleep apnea syndrome (OSAS) in women appears to increase with age. Diminishing progesterone levels during menopause may be a cause of OSAS, as progesterone is a known respiratory stimulant and upper airway dilator1

• Increased body weight associated with menopause may also be a cause. However, menopause is associated significantly with increased risk of OSAS, independently of body weight2

• Some of this effect may be mediated by testosterone, which may decrease the threshold for the occurrence of apnea3

Treatment of Insomnia in Symptomatic Women During Menopausal Transition or Postmenopause1-5

• Overall, sleep hygiene measures, sleep agents, and behavioral approaches might be helpful

• Few studies have focused on these specific subpopulations. Among these, positive results have been described with use of:

- Hormonal therapy

- Antidepressants (with comorbid conditions)

- Hypnotic agents1. Dorsey CM, Lee KA, Scharf MB. Clin Ther. 2004;26:1578-1586.2. Polo-Kantola P, Erkkola R, Irjala K, Pullinen S, Virtanen I, Polo O. Fertil Steril. 1999;71:873-880.3.

Sleep Hygiene Rules1,2

Rule Rationale

1. Curtail time in bed Excessive time in bed can lead to fragmentation of sleep

2. Keep a regular sleep schedule (especially morning rise time)

Stabilization of circadian rhythms; limits time in bed (rule 1)

3. Eliminate the bedroom clock Watching the clock can lead to rumination and worry during nighttime wakefulness

4. Exercise in the afternoon/early evening

May deepen sleep and if timed correctly, may shorten sleep onset

5. Avoid caffeine, nicotine, and alcohol

All can negatively impact sleep. Caffeine and nicotine are stimulants. Metabolism of alcohol disrupts sleep

Page 44: Insomnia: Special Considerations for Specific Populations of Women Kin M. Yuen, MD, MS FAASM, D, ABSM Medical Director Bay Sleep Clinic, CA

Sleep Hygiene Rules1,2 (cont’d)

Rule Rationale

6. Eat a light bedtime snack Avoids awakenings from drop in blood sugar at night

7. Sleep in a quiet, dark bedroom Noise and light cause awakenings from sleep. Light also impacts circadian rhythms

8. Enhance sleep environment Comfortable temperature, good mattress

9. Avoid “trying” to sleep Reduces development of anxiety/worry about sleeplessness

10. Limit or avoid daytime napping

Daytime napping reduces the amount of sleep needed at night

Estrogen in the Management of Sleep Disturbance

• Estrogen improves sleep quality in menopause• Improvement in sleep only partially associated

with reduction in hot flashes• Estrogen is likely impacting sleep independent of

vasomotor symptoms

Page 46: Insomnia: Special Considerations for Specific Populations of Women Kin M. Yuen, MD, MS FAASM, D, ABSM Medical Director Bay Sleep Clinic, CA

Sleep Improvements With Hormone Therapy

• Sleep disturbance improved in symptomatic and asymptomatic women

In Summary…

• Hormone variations may contribute to the development of some mood, sleep, and somatic complaints—windows of vulnerability

• Hormone milieu and/or hormone interventions may attenuate the risk for/severity of these complaints—windows of opportunity

Page 54: Insomnia: Special Considerations for Specific Populations of Women Kin M. Yuen, MD, MS FAASM, D, ABSM Medical Director Bay Sleep Clinic, CA

In Summary…(cont’d)

• Insomnia appears to be more prevalent in aging women and may occur in the absence of HF

• Estrogen therapy may improve subjective sleep quality and well-being. Improvement may occur regardless of the presence of HF; the use of different progestins may attenuate the benefits

Page 55: Insomnia: Special Considerations for Specific Populations of Women Kin M. Yuen, MD, MS FAASM, D, ABSM Medical Director Bay Sleep Clinic, CA

In Summary…(cont’d)

• Studies on hormone therapy and objective sleep quality measures, including sleep-disordered breathing, have shown mixed results

• Antidepressants may be effective, particularly with comorbid HF, depression and/or anxiety

• Hypnotics may be an effective, safe treatment for insomnia and improvement of daytime function during menopause
