Neurology, Sleep
Conditions
Brief summary
This study aims to establish a research cohort on sleep and sleep disorders in patients with neurological diseases to systematically evaluate the relationship between various neurological conditions and sleep characteristics or disturbances.
Detailed description
The cohort will include patients with confirmed diagnoses such as stroke, Parkinson's disease, epilepsy, cognitive disorders, neuroinfections, and immune-mediated neurological diseases, with collection of demographic data, medical history, and lifestyle factors. All participants will undergo standardized polysomnography (PSG), sleep questionnaires, assessments of cognition, mood, daytime function, as well as relevant imaging and laboratory tests. Designed as a prospective observational study, the cohort will focus on sleep architecture alterations, periodic limb movements, sleep-disordered breathing, REM sleep behavior disorder, nocturnal awakenings, heart rate, and oxygen saturation, and their associations with disease severity and progression. The data will provide a basis for exploring the mechanisms, early indicators, and potential interventions for sleep disturbances in neurological patients.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Total sleep time measured by polysomnography | baseline, 3 months and one year | Total sleep time is defined as the total amount of time spent asleep during the overnight polysomnography recording, expressed in minutes. |
| Wake after sleep onset measured by polysomnography | baseline, 3 months and one year | Wake after sleep onset is defined as the total duration of wakefulness after sleep onset and before final awakening during the overnight polysomnography recording, expressed in minutes. |
| Sleep onset latency measured by polysomnography | baseline, 3 months and one year | Sleep onset latency is defined as the time from lights off to the first epoch of sleep during overnight polysomnography. |
| Number of arousal events measured by polysomnography | baseline, 3 months and one year | The number of arousal events is defined as the total number of arousals occurring during the overnight polysomnography recording. |
| Rapid eye movement sleep onset latency measured by polysomnography | baseline, 3 months and one year | Rapid eye movement sleep onset latency is defined as the interval between sleep onset and the first occurrence of rapid eye movement sleep during the overnight polysomnography recording, expressed in minutes. |
| Non rapid eye movement sleep stage 1, 2, 3, and rapid eye movement sleep time measured by polysomnography | baseline, 3 months and one year | Non-rapid eye movement (NREM) sleep stages 1, 2, and 3, and rapid eye movement (REM) sleep time are defined as the total duration spent in each sleep stage during overnight polysomnography, expressed in minutes. |
| Number of awakenings related to the event measured by polysomnography | baseline, 3 months and one year | The number of awakenings related to respiratory events is defined as the total count of awakenings temporally associated with respiratory events during overnight polysomnography. |
| Number of respiratory events measured by polysomnography | baseline, 3 months and one year | The number of respiratory events is defined as the total count of apnea and hypopnea events identified during overnight polysomnography. |
| Number of decreases in oxygen saturation measured by polysomnography | baseline, 3 months and one year | The number of respiratory events is defined as the total count of respiratory events identified during overnight polysomnography. |
| Sleep period heart rate measured by polysomnography | baseline, 3 months and one year | Sleep period heart rate is defined as the average heart rate measured during the sleep period as recorded by overnight polysomnography. |
| Number of rapid eye movement sleep without atonia measured by polysomnography | baseline, 3 months and one year | The number of rapid eye movement sleep without atonia events is defined as the total count of rapid eye movement sleep epochs exhibiting increased muscle activity during overnight polysomnography. |
| Hypoxic burden measured by polysomnography | baseline, 3 months and one year | Hypoxic burden is a quantitative measure of the cumulative severity of nocturnal hypoxemia, calculated from overnight polysomnography. It represents the total area under the curve of oxygen desaturation events, integrating both the depth and duration of oxygen desaturation across the entire sleep period. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The score of Insomnia Severity Index scale | baseline, 3 months and one year | The total score ranges from 0 to 28, and a higher score indicates higher levels of insomnia severity. A score of 8 or greater is the cut point for clinically possible insomnia. |
| The score of 14-item Hamilton anxiety rating scale | baseline, 3 months and one year | The total score ranges from 0 to 56, and a higher score indicates higher levels of anxiety symptoms. A score of 7 or greater is the cut point for clinically possible anxiety. |
| The score of 17-item Hamilton depression rating scale | baseline, 3 months and one year | The total score ranges from 0 to 52, and a higher score indicates higher levels of depression symptoms. A score of 7 or greater is the cut point for clinically possible depression symptom |
| The score of montreal cognitive assessment scale | baseline, 3 months and one year | The total score ranges from 0 to 30, with higher scores indicating better global cognitive function. A score below 26 is commonly used as the cut-off for cognitive impairment. |
