简要总结
The crude prevalence rate of Parkinson's disease in Upper Egypt governorates ranging from 557-436/100,000 (Assiut and Qena governorates respectively) which was one of the highest prevalence of PD around the world .Parkinson's disease patients report having complaints of disrupted sleep anywhere from 60 to 98 %. This is one of the most common non-motor symptoms, and it is a substantial contributor to the diminished quality of life associated with Parkinson's disease. PD patients have poor sleep maintenance and fragmentation (Comella 2007, Khedr et al. 2013). Khedr et al (2013) found that; 78.6% out of 112 patients with PD had sleep disturbances with the commonest complaint being difficulty getting to sleep at night or staying asleep (46.4%) followed by vivid nightmares and night terrors (27.7%). In other studies, 80-90% of PD patients have had sleep difficulty with virtually all patients having symptoms at some time in the course of the disease .
详细描述
The pathophysiology of PD sleep problems is unclear. Degeneration of major sleep control centers in the brainstem is a leading factor . In addition to dopaminergic medication, nocturnal akinesia, depression and restless legs syndrome, may contribute to sleep disturbances in Parkinson's disease .Previous studies linked dopaminergic impairment in the hypothalamus to sleep disturbances in PD.
Repetitive transcranial magnetic stimulation (rTMS), non-invasive magnetic stimulation of the cerebral cortex is utilized as non-pharmacological therapy in PD with varying degree of results on the motor symptoms. rTMS has also an impact sleep organization in healthy people both during and before sleep.
The effects of rTMS on sleep have been studied in PD in two previous studies, both of which applied HF over either the motor or parietal cortex. They reported improvement in sleep by subjective and objective measures. However, one of the studies found that the improvement seen on polysomnographic (PSG), the other study found improvement in actigraphic recordings. One sham-controlled trial of the effect of rTMS on sleep in patients with PD also revealed substantial placebo-related improvement on subjective questionnaires (i.e., Parkinson Disease Sleep Scale, Hamilton Depression Rating Scale, Unified Parkinson Disease Rating Scale), with sleep improvement found equally between active and sham stimulation groups . Interestingly, in this trial rTMS showed no changes recorded in actigraphy parameters.
Huang et al. 2018 examined the effect of LF rTMS over the parietal cortex in patients who had generalized anxiety disorder with comorbid insomnia and assessed Hamilton Rating Scale for Anxiety (HRS-A), and PSQI. In their trial, PSQI improvements were seen in active rTMS but not in sham stimulation, making this the second trial of a sham-controlled trial without pronounced placebo effect. Additionally, a positive correlation was seen between improvement in the HRSA anxiety scores and PSQI scores which could suggest that sleep improvement was associated with anxiety improvement. It was not known whether the improvement seen in insomnia and anxiety was independent, and whether rTMS really had an intrinsic role in sleep (Rosenquist and McCall 2019) In another study, Jiang et al. 2013 evaluated the effect of rTMS versus medication versus cognitive behavioral therapy in chronic insomnia. They performed the assessments with PSG and PSQI. Based on PSG findings, rTMS only showed superior improvement in stage 3 and rapid-eye movement sleep.
According to the above mentioned studies rTMS seems to have the ability to improve sleep disorders.

盲法说明
Out of 45 PD patients, 30 patients had sleep disturbance and 6 out of them refused to be participated in the study . Group allocations (active or vs sham with ratio 2 (16 cases):1(8 cases) were placed in serially numbered closed envelopes.

排除标准
- •Patients with PD with disturbed conscious level, severe cognitive impairment, psychosis, and medical problems such as (Renal failure, Liver cell Failure, Respiratory Failure, and endocrinal impairment), patients with other types of Parkinsonism as (Multisystem atrophy, supranuclear palsy, and encephalitic Parkinsonism) and patients had contraindication of magnetic stimulation (metallic piece, pacemaker, epilepsy) were also excluded from the study
结局指标
主要结局
Parkinson's disease sleep scale (PDSS)
时间窗: 1 month
The PDSS is a visual analogue scale addressing 15 commonly reported symptoms associated with sleep disturbance overall quality of night's sleep (item 1); • sleep onset and maintenance insomnia (items 2 and 3); • nocturnal restlessness (items 4 and 5); • nocturnal psychosis (items 6 and 7) • nocturia (items 8 and 9); • nocturnal motor symptoms (items 10-13); • sleep refreshment (item 14); • daytime dozing (item 15).
polysomenography
时间窗: 1 month
This polysomnography systematically monitored the electroencephalogram (EEG) (C3-A2, C4-A1), electrooculogram (EOG), electromyogram of the chin (EMG), electrocardiogram (EKG), body positions, nasal and oral airflow, thoracic and abdominal effort, limb movements, pulse oximetry, and snoring sound level.
次要结局
- Unified Parkinson's Disease Rating Scale (UPDRS)(1 month)
- Beck Depression Inventory(1 month)
- Cognitive assessment using Montreal Cognitive assessment(1 month)
