Tiltaksbeskrivelse |
Tidsramme |
|---|---|---|
|
Mini-mental State Examination
Tidsramme: baseline
|
Mini-Mental State Examination (MMSE) is a 30-item cognitive screening tool assessing orientation, memory, attention, calculation, and language, with total scores ranging from 0 to 30.
Higher scores indicate better cognitive function.
Scores ≥27 generally indicate normal cognition, while lower scores suggest varying degrees of impairment, with cutoffs adjusted for education and age.
|
baseline
|
|
Montreal Cognitive Assessment
Tidsramme: baseline
|
Montreal Cognitive Assessment (MoCA) is a 10-15 minute screening tool covering 8 cognitive domains through 12 tasks, with total scores ranging from 0 to 30.
Higher scores indicate better cognitive function.
Scores ≥26 are generally considered normal, with a 1-point adjustment for education ≤12 years; scores <26 suggest possible cognitive impairment.
|
baseline
|
|
The 39-Item Parkinson's Disease Questionnaire
Tidsramme: baseline
|
Non-Motor Symptoms Scale (NMSS) assesses frequency and severity of non-motor symptoms across all stages of Parkinson's disease, covering autonomic, affective, cognitive, sleep, and other domains.
Total scores range from 0 to 360.
Higher scores indicate worse outcome (greater symptom burden).
|
baseline
|
|
Hamilton Depression Rating Scale
Tidsramme: baseline
|
Hamilton Depression Rating Scale (HAM-D) is a clinician-rated instrument assessing depression severity across multiple dimensions including mood, somatic symptoms, anxiety, and sleep disturbance.
The 17-item version (HAM-D17) yields total scores ranging from 0 to 52.
Higher scores indicate worse outcome (greater depressive symptom severity), with scores ≥23 indicating very severe depression.
|
baseline
|
|
hoehn-yahr stage
Tidsramme: baseline
|
Hoehn and Yahr Scale (HY) is a clinician-rated instrument assessing clinical severity and disease staging in Parkinson's disease.
Staging ranges from 0 (no symptoms) to 5 (severe disability requiring full dependence).
Higher stages indicate worse outcome (more advanced disease with greater functional impairment), primarily based on postural instability and disability.
|
baseline
|
|
Movement Disorder Society-Sponsored Revision Of The Unified Parkinson's Disease Rating Scale
Tidsramme: baseline
|
Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) is a comprehensive instrument assessing Parkinson's disease across four parts: non-motor symptoms, activities of daily living, motor symptoms, and complications.
Total scores range from 0 to 260 (Part I: 0-52, Part II: 0-52, Part III: 0-132, Part IV: 0-24).
Higher scores indicate worse outcome (greater impairment).

|
Wearable devices measure gait parameters
Tidsramme: baseline
|
Wearable Device System (GYENNO MATRIX) is a 10-sensor system sampling at 100 Hz to capture 3D angular velocity, acceleration, and geomagnetic field data.
It extracts gait parameters (step length, stride, gait cycle) and detects postural transitions (standing, sitting, turning).
|
baseline
|
|
Sniffin' Sticks 12
Tidsramme: baseline
|
Sniffin' Sticks 12 (SS-12) is a brief olfactory screening test assessing odor identification ability using 12 pen-like odor pens.
Total scores range from 0 to 12, based on the number of correctly identified odors.
Higher scores indicate better outcome (superior olfactory function).
It is widely used for early Parkinson's disease screening and cognitive disorder assessment.
|
baseline
|
|
REM sleep behavior disorderscreening questionnaire
Tidsramme: baseline
|
REM Sleep Behavior Disorder Screening Questionnaire (RBDSQ) is a 10-item self-rated scale screening for REM sleep behavior disorder, covering dream content, dream-enactment behaviors, injuries, and neurological conditions.
Total scores range from 0 to 13.
Higher scores indicate worse outcome (greater likelihood of abnormality), with scores ≥5 considered abnormal.
|
baseline
|
|
Parkinson's disease sleep scale
Tidsramme: baseline
|
Parkinson's Disease Sleep Scale (PDSS) is a 15-item scale assessing sleep disturbances in Parkinson's disease, covering nighttime quality, sleep onset, maintenance, limb discomfort, dreaming, hallucinations, nocturia, and daytime sleepiness.
Total scores range from 0 to 150 (0-10 per item).
Higher scores indicate better outcome (fewer or less severe sleep problems).
