Upstate Sleep Clinic for insomnia• H/o anxiety and depression for which she is on desvenlafaxine

and she is seeing a counselor • H/o chronic low back pain since age 18, s/p back surgery and

takes oxycodone every day• Takes zolpidem, melatonin and diphenhydramine every night

for sleep for at least 5 years• She has been on zolpidem “for too long” and would like to

come off

ICSD-‐3rd Edition• Chronic Insomnia Disorder

– >3 months• Short-‐Term Insomnia

Disorder – <3 months

• Other Insomnia Disorder– Need more history

• With or without co-‐morbidities, weather or not those are sleep disruptive

Chronic Insomnia DisorderDefinition

• 3 components– Persistent sleep difficulties• >3 nights per week, >3 months

– Despite adequate opportunity and circumstances– Leading to daytime impairment

Co-‐Morbidities Associated with Insomnia

• Medical disorders• Sleep disorders• Psychiatric disorders• Substance use, misuse or abuse

• When the insomnia is a prominent symptom, a separate insomnia diagnosis is made

Comorbid Medical Disorders

Comorbid Psychiatric Disorders

Medications and Substances

Epidemiology

• High prevalence– Chronic 5-‐10% – Short-‐Term 10-‐30%

• Risk factors– Females– Lower socio-‐economic class

– Elderly– African-‐American race– Patients with comorbid medical, mental and substance abuse disorders

– Shift work

Pathophysiology

• Physiologic hyper-‐arousal due to increased sympathetic and HT-‐pituitary-‐adrenal axis activity– Increased HR, decreased heart rate variability– Increased metabolic rate and temperature– Increased cortisol, ACTH and CRF– Increased high frequency EEG during NREM sleep

• No structural brain pathology

Obstructive Sleep Apnea– Is very common– Can present with sleep onset or maintenance insomnia

– Can overlap with insomnia

– There is no anxiety and excessive worry about being able to sleep

– Patients are sleepy during the day

Delayed Sleep Phase Disorder – Teenagers and young adults

– Sleep difficulties when trying to fall asleep at the usual sleep times

– They go to sleep later than usual

– Normal total sleep time (as long as they coordinate with endogenous circadian rhythm)

– No impairment during the day

– No night to night variability

Advanced Sleep Phase Disorder

– Elderly– They wake up early

– They go to bed early– No daytime impairment

Shift Work Syndrome

– Insomnia related to sleep during non-‐habitual times

– It is very common for shift workers to have insomnia complaints

Chronic Volitional Sleep Restriction/ Insufficient Sleep Syndrome

– Patients do not allow themselves sufficient sleep time due to work or family constraints

– Have EDS or un-‐intentional daytime sleep episodes

– Can have normal sleep if allow themselves enough time

Complications

• Hypertension, diabetes, metabolic syndrome and coronary artery disease

• Absenteeism and work disability• Increased health-‐care expenditures• Prolonged use of prescription and OTC sleep aids

Sleep Diary

Polysomnography• Abnormal

– SO>30 min– WASO>30 min– TST <6 hours– Increased N1, decreased

N3– Some patients do not sleep

at all!

• Normal– Night to night variability– “psychophysiological

insomnia– “paradoxical insomnia”

Not generally indicated unless sleep co-‐morbidities are

suspected

• Tiagabine• L-‐tryptophan

Issues with 2016 AASM Guidelines

• The clinical improvement thresholds were determined based on task force judgment

• Physicians treat patients with insomnia based of patient’s reported distress, not by objective measures of sleep parameters

• Insomnia is not classified as sleep onset or maintenance anymore

• Evidence for/against is poor, so recs are weakJ Clin Sleep Med. 2017;13(2):307–349.

• We do not know how the clinically significant change in SOL, WASO and TST

• Absolute mean effect versus placebo was small

• Most patients in trials were white, middle-‐age females without co-‐morbidities

Ann Intern Med. 2016;165(2):103-‐112.

Pharmacotherapy Harms

• Most studies are not adequately powered to detect rare but serious side effects– falls, fractures – car accidents– sleep walking, sleep driving

– dementia– cancer– increased mortality.

• Hypnotics only approved for 4-‐5 weeks by FDA and PRN basis.

• Decreased dosages are recommended in elderly, debilitated and women
