Title: Effect of Self-Management on Improving Sleep Apnea Outcomes
Brief Summary: Obstructive sleep apnea syndrome (OSA) is a common sleep disorder that is associated with serious medical and psychological complications. Nasal continuous positive airway pressure (CPAP) is the treatment of choice for this condition because it is highly effective in reducing the frequency of nocturnal respiratory events, improving sleep architecture, decreasing daytime sleepiness and improving blood pressure. Incomplete patient adherence, however, limits the effectiveness of CPAP therapy and results in sub-optimal patient outcomes. Previous efforts to enhance CPAP adherence have resulted in only modest improvements, have generally not been theory-driven, and have had minimal effects on key patient outcomes such as reduction in OSA symptoms or increase in health-related quality of life (HRQOL). The planned intervention in this proposal, the Sleep Apnea Self-Management Program (SASMP), is based on the rationale that sleep apnea is a chronic disease that requires significant self-care on the part of the patient. We draw on the extensive chronic disease self-management literature to provide a solid theoretical justification for this pragmatic intervention both to better manage key aspects of OSA and to increase CPAP adherence. Chronic disease management programs help reduce symptoms, improve HRQOL, improve treatment adherence, and decrease medical utilization.


Options:
A: Inclusion Criteria:

1. Men and women ≥ 65 years old.
2. Patients diagnosed with OSA with an apnea-hypopnea index per hour \>30.
3. Patients with an Epworth Sleep Scale score ≤ 12 (without excessive daytime sleepiness).
4. Signed written informed consent.

Exclusion Criteria:

1. Patients with severe chronic diseases: cardiovascular or pulmonary, neurological (stroke, epilepsy, head injury...) or psychiatric.
2. Any current significant systemic illness or unstable medical condition that could lead to difficulty in complying with the protocol or may, in the opinion of the investigator, compromise the conclusions.
3. Mini Mental State Exam (MMSE) \<24.
4. Any MRI exclusions - presence of aneurysm clips, pacemakers, mechanic heart valves, ear implants, metal fragments or foreign objects in the eyes, skin or body.
5. Previous CPAP treatment.
6. Psycho-physical inability to complete questionnaires. Inadequate visual and auditory acuity will be excluded.
7. Presence of any previously diagnosed sleep disorders: narcolepsy, insomnia, chronic sleep deprivation, REM behavior disorder and restless leg syndrome.
8. Patients with \> 50% of central apneas or the presence of Cheyne-Stokes Respiration.
9. History of alcohol abuse or dependence.
B: Inclusion Criteria:

* Clinical diagnosis of obstructive sleep apnea
* No previous use of CPAP
* Must be a Veteran with residence within San Diego County

Exclusion Criteria:

* Home oxygen therapy
* Fatal comorbidities (i.e., life expectancy less than 6 mos)
* Contraindications for CPAP use
C: Inclusion criteria

Participants are included in the study if all of the following criteria are met:

(1) Are able to provide written informed consent by self or legally authorized representative. MacArthur Competency Assessment Tool for Clinical Research (MacCAT-CR) will be used to assess decision making capacity; (2) OSA defined as an apnea-hypopnea index (AHI) ≥10, using either a clinical split- or whole-night polysomnography. We chose an AHI cut-off of ≥10 as opposed to ≥15, the conventional cut-off for moderate OSA because split-night studies underestimate the AHI; (3) education-adjusted scores of 28-35 on the modified Telephone Interview for Cognitive Status; (4) 0-0.5 on the Clinical Dementia Rating (CDR); (5) 24-30 on the Mini-Mental State Examination (MMSE); (6) memory impairment approximately 1.0-1.5 standard deviations below normal (adjusted for age and education), determined by scores on the Logical Memory II test; (7) performance approximately 1.0-1.5 standard deviations below normal (adjusted for age and education) in no more than one cognitive domain in addition to memory; (8) medications stable for at least 4 weeks; washout from psychoactive medications (e.g., excluded anti-depressants, neuroleptics, chronic anxiolytics, and sedative hypnotics) for 4 weeks; (9) score of ≤28 on the 21-item Beck Depression Inventory II; (10) a study partner who spends at least 10 hours per week in phone or in-person contact with participant; (11) visual and auditory acuity for testing; (12) 6 or more grades of education completed, or a history to exclude intellectual disability; and (13) English fluency.

Exclusion criteria

Patients are excluded from participating in this study if 1 or more of the following criteria are met:

(1) significant neurologic disease other than MCI; (2) MRI exclusions, e.g. metal; (3) psychiatric disorders, including uncontrolled major depression, bipolar disorder, or schizophrenia; (4) history of alcohol dependence within 6 months; (5) current significant unstable medical condition; (6) participation in studies involving neuropsychological testing; (7) currently receiving CPAP; (8) requiring oxygen during CPAP; (9) dementia indicated by impairment in 3-5 age and education adjusted cognitive domains.
D: Inclusion Criteria:

* Adults (18-70 yrs of age) with a subacute stroke (1-12 months)
* Diagnosis of sleep apnea and acceptance of CPAP therapy:

Exclusion Criteria:

* Patients with sopor/coma
* Any form of dementia (Mini-Mental State Examination \<20)
* Previously diagnosed sleep apnea and established CPAP therapy
* Purely central sleep apnea
* Chronic obstructive pulmonary disease more than Gold III
* Cancer
* Severe kidney diseases
* Coexisting causes of daytime sleepiness (e.g. narcolepsy, night or rotating shift-work; self-reported average sleep duration \<4 h)
* A major psychiatric or any other acute medical condition
* Patients unable or unwilling to comply with the protocol
