Parkinson's Disease May Raise Risk for Sleep Disorders

A new study indicates that Parkinson’s disease (PD) patients may have a higher risk for sleep-disordered breathing (SDB). The study was published by the journal Sleep and Breathing.

Sleep-disordered breathing includes everything from harmless snoring to the serious medical condition called obstructive sleep apnea.

The study involved 134 PD patients and 94 control subjects. The participants had no prior diagnosis of SDB.

Each person’s risk for SDB was assessed by the Berlin Questionnaire. Participants also took questionnaires that assessed their quality of life.

Results indicate that PD patients have increased risk for SDB. High risk for SDB was apparent in 49.3 percent of PD patients. In contrast, 34.8 percent of the controls showed high risk.

After adjusting for age, gender, and body mass index, PD subjects still had a higher risk.

PD patients at high risk for SDB had higher BMIs and Epworth scores. In the general population, excess weight and sleepiness are also factors for SDB.

Data showed that SDB might substantially affect depression and lower quality of life in PD patients.

The researchers suggest that screening for, diagnosing and treating SDB in PD patients could significantly raise their quality of life.
