RECRUITINGIdentification of a change of recognizable signs or symptoms
Identification of recognizable signs or symptoms and their time course prior to disease-onset defined by the presence of a spastic gait and at least one of three additional features: 1. manifest spasticity in the clinical examination (Ashworth Scale \>0) 2. positive Babinski sign 3. pyramidal pattern of muscle weakness (e.g. hip abduction or foot elevation preferentially involved)
Time frame: every two years, up to eight years
Subclinical progression (10m walking time)
To identify measures of subclinical progression of motor symptoms prior to disease onset by comparing functional performance in mutation carriers with that in individuals without mutation.
Time frame: every two years, up to eight years
Subclinical progression (5-stair climbing test time)
To identify measures of subclinical progression of motor symptoms prior to disease onset by comparing functional performance in mutation carriers with that in individuals without mutation.
Time frame: every two years, up to eight years
Subclinical progression (3 minute walking test (3MW))
To identify measures of subclinical progression of motor symptoms prior to disease onset by comparing functional performance in mutation carriers with that in individuals without mutation.
Time frame: every two years, up to eight years
MRI (not obligate) - DTI
To reveal alterations in brain morphology with magnetic resonance im-aging (MRI) in presymptomatic mutation carriers by measuring diffusion tensor imaging (DTI).
Time frame: every two years, up to eight years
MRI (not obligate) - volumetry
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
MRI will be used to reveal presymptomatic brain morphology changes (not obligate)
Electrophysiological tests will be used to characterize patients better.
By using the 3 minute walk, 5 stair-climb test, and 10m walking test we will try to identify and measure subclinical progression prior to disease onset
By using a number of different tests we try to identify other non-motor symptoms which might manifest prior to disease onset.
To reveal alterations in brain morphology with magnetic resonance im-aging (MRI) in presymptomatic mutation carriers by measuring brain volumetry.
Time frame: every two years, up to eight years
Nfl
To compare Nfl levels in serum (and cerebrospinal fluid (CSF) - not obligate) in mutation carriers and non-carriers.
Time frame: every two years, up to eight years
Non-motor symptoms (SPRS inventory V3)
To identify clinical signs (other than spasticity) that are more frequent in mutation carriers than in non-carriers as recorded by the SPRS inventory V3.
Time frame: every two years, up to eight years
Non-motor symptoms (quality of life)
To identify clinical signs (other than spasticity) that are more frequent in mutation carriers than in non-carriers as recorded by the EQ-5D.
Time frame: every two years, up to eight years
Non-motor symptoms (fatigue)
To identify clinical signs (other than spasticity) that are more frequent in mutation carriers than in non-carriers as recorded by the MFI.
Time frame: every two years, up to eight years
Non-motor symptoms (pain)
To identify clinical signs (other than spasticity) that are more frequent in mutation carriers than in non-carriers as recorded by the Brief Pain Inventory.
Time frame: every two years, up to eight years
Non-motor symptoms (depression)
To identify clinical signs (other than spasticity) that are more frequent in mutation carriers than in non-carriers as recorded by the Becks Depression Inventory (BDI).
Time frame: every two years, up to eight years
Non-motor symptoms (restless-legs)
To identify clinical signs (other than spasticity) that are more frequent in mutation carriers than in non-carriers as recorded by the restless-legs diagnostic criteria questions.
Time frame: every two years, up to eight years
SPRS
To determine the sensitivity of the Spastic Paraplegia Rating Scale (SPRS) to detect the manifestation of disease onset as defined above.
Time frame: every two years, up to eight years
Cognition (CANTAB)
To compare cognitive performance by using the CANTAB battery in mutation and non-mutation carriers
Time frame: every two years, up to eight years
Cognition (MoCA)
To compare cognitive performance by using the Montreal Cognitive Assessment (MoCA) in mutation and non-mutation carriers
Time frame: every two years, up to eight years
