Summary
Sleep apnoea syndromes, often presenting with neurological symptoms, were documented in 13% of Indian neurology outpatients. Excessive daytime somnolence and snoring were key indicators in obese, middle-aged males.
Area of Science:
- Neurology
- Sleep Medicine
Background:
- Sleep apnoea syndromes are recognized disorders with neurological manifestations.
- Systematic reporting in Indian literature remains limited.
Purpose of the Study:
- To investigate the prevalence and characteristics of sleep apnoea syndromes in Indian neurology outpatients.
- To highlight the association between sleep disturbances and neurological presentations.
Main Methods:
- Clinical evaluation of 12,000 neurology outpatients over two years.
- Polysomnography (video EEG) conducted on 60 patients with primary sleep disturbances.
- Analysis of patient demographics, symptoms, and sleep study results.
Main Results:
- Sleep apnoea was diagnosed in 8 out of 60 (13%) patients.
- Obstructive sleep apnoea (5 patients) and mixed sleep apnoea (3 patients) were identified.
- Affected patients were predominantly obese (mean weight 82kg), middle-aged males (mean age 46.3 years).
- Excessive daytime somnolence and snoring were the primary symptoms.
Conclusions:
- Sleep apnoea syndromes should be considered in patients presenting with excessive daytime somnolence.
- Obesity and symptom duration correlate with sleep apnoea severity.
- Further systematic studies are needed in the Indian population.
