Geriatric sleep apnea syndrome: a preliminary description

Area of Science:

• Gerontology
• Sleep Medicine
• Neurology

Background:

• Sleep-disordered breathing (SDB) is increasingly recognized in older adults.
• Geriatric Sleep Apnea Syndrome (GSAS) is characterized by specific diagnostic criteria and associated comorbidities.
• Understanding GSAS is crucial for addressing its impact on health and cognition in the elderly.

Purpose of the Study:

• To compare the clinical and cognitive characteristics of patients with Geriatric Sleep Apnea Syndrome (GSAS) against healthy older controls (GCON).
• To investigate the similarities between GSAS and Sleep Apnea Syndrome (SAS) in middle-aged populations.
• To identify potential diagnostic parameters for SDB in older individuals.

Main Methods:

• Comparison of 8 GSAS patients with 12 age, sex, weight, education, and socioeconomic status-matched GCON.
• GSAS diagnosis based on apnea-hypopnea index (AHI) ≥ 10 and at least two comorbidities (hypertension, cardiac arrhythmias, daytime hypersomnolence).
• Assessment of sleep disturbance, subjective sleepiness, depression, and cognitive functions (nonverbal problem solving and memory).

Main Results:

• GSAS patients showed significantly higher AHI, frequency of hypertension, and poorer performance on the Multiple Sleep Latency Test compared to GCON.
• GSAS group reported greater sleep disturbance, subjective sleepiness, and depression.
• Cognitive assessments revealed lower scores in nonverbal problem solving and nonverbal memory for GSAS patients.

Conclusions:

• Geriatric Sleep Apnea Syndrome presents with significant sleep disturbance, mood, and cognitive impairments, mirroring findings in middle-aged SAS populations.
• GSAS shares clinical and cognitive characteristics with Sleep Apnea Syndrome observed in younger demographics.
• Further research is warranted to refine diagnostic parameters for pathological SDB in the elderly population.
