Brain Fog in Sleep Apnea

Condition(s) studied

Study summary

Objective: This observational, cross-sectional pilot study aims to assess "Brain Fog" (cognitive symptoms impacting memory, attention, and concentration) in severe Obstructive Sleep Apnea (OSA) patients. It compares two groups: those on CPAP treatment for at least 3 months and those not yet treated.

Procedures: Severe OSA patients (AHI \> 30) will complete a 30-minute questionnaire at the Sleep Center Clinic, covering sociodemographic information, OSA diagnosis, and treatment details. Assessment scales will measure daytime sleepiness, sleep quality, and psychophysical fatigue.

Participants: 80 Sleep Center outpatients, evenly divided by age and gender:

40 with severe OSA on CPAP for at least 3 months. 40 with severe OSA not yet on CPAP. Duration: Approximately 12 months.

Eligibility

Primary outcome measure(s)

• Brain Fog — At enrollment only
  The Italian validation questionnaire is currently undergoing validation by our research group. In the original self-report scale, for each item, respondents are asked to indicate on a 5-point Likert scale (0 = "never", 1 = "rarely", 2 = "occasionally", 3 = "a lot of the time", 4 = "nearly all the time") how often they have experienced each symptom during the last two weeks. Total scale scores range from 0 to 92, with higher scores indicating increased levels of brain fog.
