| definition |
Description: Sleep disturbances can be present in many different forms. Most of the times it means that patients have trouble falling asleep, but it can also mean that patients suffer from excessive sleeping and excessive daytime sleepiness (EDS). Daytime sleepiness is defined as excessive when it causes a subjective complaint or interferes with function. The International Classification of Sleep Disorders, third Edition (ICSD-3) defines EDS as the inability to maintain wakefulness and alertness during major making episodes of the day, with sleep occurring unintentionally, or at inappropriate times almost daily for at least three months. The terms hypersomnia or hypersomnolence are sometimes used interchangeably with excessive daytime sleepiness. Fatigue refers to a subjective lack of physical or mental energy. This is scored separately because this actual word is used a lot in the clinical histories. The causes of excessive daytime sleepiness are numerous. However, in the cases of the NBB, it is often present in the context of a neurodegenerative brain disease. In the clinical summaries of the NBB, it is frequently noted as ‘sleeping problems’, without further specification. We might assume that by sleeping problems, the neurologists had asked for, generally mean that the patient had trouble sleeping. For this project and because we use a machine learning approach, we have decided to score all “sleeping problems”, including all the possible symptoms, like excessive daytime sleepiness’, hypersomnia, and hypersomnolence. Because we can assume that most of the times a sleeping problem is reported, it means “not being able to sleep as well as before”. |

| Exclusion_criteria |
We score as TRUE: sleeping problems; sleeping disturbances; insomnia; trouble sleeping; difficulty sleeping; difficulty falling asleep; difficulty maintaining sleep; excessive daytime sleepiness; hypersomnia; hypersomnolence. We did NOT score: When it says that the patient looked somnolent, this is more an observation during neurological examination, and is more about the level of consciousness (this is an observation); This was not scored anywhere. We did NOT score: day-night rhythm disturbances; changes in circadian rhythm. These were scored separately as ‘Day night rhythm disturbances'. We did NOT score: REM sleep behavior or REM sleep behavior disorder (RBD). These were scored in a separate section of the database. We did NOT score: night-time restlessness; restlessness. These were scored separately as ‘Restlessness’. We did NOT score: fatigue, tiredness. These were scored separately as ‘Fatigue’. We did NOT score: any ambiguous sentence such as ‘patient had a changed sleeping pattern’ (i.e. It is not clear if this is day-night alteration). This was not scored anywhere. Explanation: Because multiple words are used interchangeably to address sleeping disturbances, we have decided to score multiple words that indicate sleeping disturbances. This might mean that we include a few cases that might report sleeping problems in the context of a central disorder of hypersomnolence for example, like narcolepsy. However, if we do not include these multiple variables, we might miss a lot of data. Together with the Clinical Diagnoses the sleeping disturbances can be placed into context. |
