The Effect of Obstructive Sleep Apnea and Its Treatment on Decision Making

March 4, 2022 updated by: Robert L. Owens, University of California, San Diego
Obstructive sleep apnea (OSA) is an extremely common disease with inadequately explored neurocognitive consequences. The investigators will study OSA patients before and after treatment to understand how OSA changes decision making abilities, and whether treatment can reverse such cognitive changes. These results could provide deeper insight into how OSA affects decision making either temporarily or permanently, and provide another rationale or motivation for treatment of OSA in adults.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The investigators hypothesize that OSA will lead to (H1) more reward-seeking and lower payoffs in the Iowa Gambling task, replicating previous findings; (H2) greater discounting of future rewards in financial choices; and (H3) these effects would dissipate when OSA is successfully treated.

In order to test these hypotheses, the investigators will perform cognitive tests (Iowa gambling; intertemporal choice; other measures) in 100 patients about to undergo sleep testing. It is expected that of these 100 patients, some will have no sleep apnea; some will have sleep apnea and will be successfully treated; and that some will have sleep apnea but will not be successfully treated by the time of repeat testing. The investigators will repeat testing using the same instruments 2 months later.

Thus the investigators will be able to compare whether OSA patients differ from control at baseline (t1), and whether OSA patients' performance will improve after treatment at t2, compared to the control at t2.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Subjects aged 18-75 referred to the UCSD Sleep clinic for either home or in-laboratory testing will be considered for inclusion in the study.

Description

Inclusion Criteria:

Subjects aged 18-75 referred to the UCSD Sleep clinic for either home or in-laboratory testing will be considered for inclusion in the study. Inclusion will not depend on gender, race or ethnicity, as per the following:

  1. 100 participants will be enrolled at the UCSD Sleep Clinic at Chancellor Park.
  2. Ages 18-75
  3. Gender: Men and woman
  4. Ethnic background: All
  5. Health Status: to the UCSD Sleep clinic for either home or in-laboratory testing

Exclusion Criteria:

  1. Ongoing CPAP treatment for OSA
  2. Inability to use a tablet device (e.g. no reading glasses, or unfamiliar with devices).
  3. Severe cardiopulmonary disorder that requires treatment with supplemental oxygen therapy.
  4. Inability to speak English fluently, as some of the questionnaires/tests are only validated in English.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Iowa Gambling Task
Time Frame: 2 months (baseline, 2 months later)
The Iowa Gambling Task is a psychological task thought to simulate real-life decision making. It is completed on a computer and takes about 10 minutes. It is widely used in research on cognition.
2 months (baseline, 2 months later)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Cognitive Reflection Test (CRT)
Time Frame: 2 months (baseline, 2 months later)
The Cognitive Reflection Test (CRT) is a task designed to measure a person's tendency to override an incorrect "gut" response and engage in further reflection to find a correct answer. It takes about 3 minutes to complete.
2 months (baseline, 2 months later)
Change in Intertemporal Choice
Time Frame: 2 months (baseline, 2 months later)
Intertemporal choice is the study of how people make choices about what and how much to do at various points in time, when choices at one time influence the possibilities available at other points in time. These choices are influenced by the relative value people assign to two or more payoffs at different points in time. It takes about 3 minutes to complete.
2 months (baseline, 2 months later)
Change in Balloon Analogue Risk Task (BART)
Time Frame: 2 months (baseline, 2 months later)
The Balloon Analogue Risk Task (BART) is a computerized measure of risk taking behavior. The BART models real-world risk behavior through the conceptual frame of balancing the potential for reward versus loss. It takes less than 2 minute to complete.
2 months (baseline, 2 months later)
Change in Epworth Sleepiness Score
Time Frame: 2 months (baseline, 2 months later)
An 11 item questionnaire that is commonly used to assess for excessive daytime sleepiness (range 0-24 points, >10 considered excessively sleepy).
2 months (baseline, 2 months later)
