Evaluation de la qualité du sommeil chez 35 parkinsoniens. Abstract : Sleep disorders are diverse in Parkinson's disease. We aimed to
assess the quality of sleep in patients with Parkinson's disease in an African
population. METHODS: In a transversal and prospective study from April to June
2014, all parkinsonian patients followed at the Fann Teaching Hospital Neurology
Clinic (Dakar, Senegal) were assessed using the Hoehn and Yahr's scale and filled
out the following questionnaires: Parkinson's disease sleep scale (PDSS), the
Pittsburgh Sleep Quality Index (PSQI), and the Epworth Sleepiness Scale (ESS). A
PDSS score<82 (or a subscore<5) and a PSQI score>5 indicated poor quality or
impaired sleep. An ESS score>10 indicated excessive daytime sleepiness. We used
the Pearson coefficient to search for correlation between age, disease stage,
disease duration, and the importance of sleep impairment. RESULTS: Hoehn and Yahr
staging was 2.42+/-0.90 in the 35 patients (60% male, mean age 65.7+/-7.4years,
disease duration 32.4+/-23.4months). The mean total PDSS score was 99.5+/-24.1
and 74.3% of the patients had an abnormally high PSQI score, indicating high
frequency and intensity of sleep disorders. Most frequent disorders were pain or
cramps interrupting sleep, night waking to urinate and fatigue or sleepiness on
waking. Patients exhibited excessive diurnal sleepiness in 22.9% of the cases;
they often had an abnormal PSQI score. Both the total PDSS score and the
difficulty to sleep increased with disease stage, but not with age or disease
duration. CONCLUSION: We found evidence of major alteration of sleep quality in
Senegalese Parkinson patients.
