In a nutshell
This study reviewed the impact of deep brain stimulation (DBS) on sleep in patients with Parkinson's disease (PD). Researchers suggested that DBS improves sleep in patients with PD.
Some background
PD is a chronic disease that affects brain cells. These cells lose their ability to control body functions causing physical and non-physical symptoms. Non-physical symptoms such as sleep disorders are often just as disabling as physical problems. Sleep disorders in PD are common and can also be related to the medication.
DBS consists of implanting a medical device in the brain. This device sends electrical impulses to specific areas. It is recommended in the treatment of physical symptoms associated with PD. However, its effectiveness in treating sleep disorders in these patients is not clear.
Methods & findings
This study reviewed 72 other studies including information about patients with PD and sleep problems. The DBS impact on sleep was measured by polysomnography, a sleep study. This study records brain waves, the blood oxygen level, heart rate, as well as eye and leg movement during sleep.
DBS improved sleep latency (how long it takes to fall asleep) and wake after sleep factors. Other nocturnal (at night) physical and non-physical symptoms such as nocturia (waking at night to urinate) also may improve with DBS. DBS had no significant impact on the eye and leg movement during sleep.
The bottom line
This study concluded that DBS improves the symptoms of sleep disorders in patients with Parkinson's disease.
The fine print
This study was based on medical records. Some information might have been incomplete. This might affect the results.
