Patient information

For patients with chronic diseases such as neurodegenerative disorders (NDD) and immune-mediated inflammatory diseases (IMID), a key attribute for any successful therapeutic intervention is its ability to improve the patients’ activities of daily living (ADL) and health-related quality of life (HRQoL). Current evaluations of ADL and HRQoL rely mainly on subjective reports, typically using standardized questionnaires provided by patients every few months. The approach is often prone to recall bias, reliability issues and poor sensitivity to change. IDEA-FAST wants to change this!

The goal is to identify, profile and validate digital solutions based on mobile or residential technology for remote assessment of fatigue and sleep disturbances that could effectively be used as digital endpoints in assessments for RA, SLE, PSS, IBD, PD, HD and beyond. Identifying digital endpoints for fatigue and sleep disturbances that can be used in patients’ usual living environment will also enable the meaningful evaluation of impacts of these symptoms on ADL/HRQoL. The ecological validity of these digital endpoints will be tested using a large longitudinal cohort of four IMID and two NDD.



Parkinson's Disease

A gradual onset progressive degenerative disease whose cardinal manifestations include bradykinesia plus one of the following - tremor, rigidity or postural instability. Nonmotor manifestations: autonomic dysfunction, neuropsychiatric features.


Huntington's Disease

A rare neurodegenerative disorder of the central nervous system. HD is an autosomal dominant disorder due to a t-mutation resulting in an increased number of triplicate cytosine-adenine-guanine repeats on chromosome 4. The manifestations include chorea, dementia and personality changes. In the Westphal variant dystonia and parkinsonism are prominent.


Rheumatoid Arthritis

Persistent and/or erosive disease defined as the confirmed presence of synovitis in at least 1 joint, absence of an alternative diagnosis that better explains the synovitis, and achievement of a total score of 6 or greater (of a possible 10) in 4 domains: number and site of involved joints, serologic abnormality, elevated acute-phase response, symptom duration.


Systemic Lupus Erythematosus

An autoimmune non-organ specific inflammatory disease characterised by the presence of antibodies to DNA, RNA and other components of the nucleus. Variable clinical presentation and course ranging from an acute fulminant life-threatening disorder with involvement of heart, central nervous system and kidneys to an indolent chronic scarring skin disorder.


Primary Sjogren’s Syndrome

A slowly progressive, systemic inflammatory autoimmune disease affecting primarily the exocrine glands. Lymphocytic infiltrates replace functional epithelium, leading to oral and ocular dryness. Characteristic autoantibodies (e.g., anti-Ro/SS-A and/or anti-La/SS-B) are produced.


Inflammatory Bowel Disease

A group of inflammatory conditions of the intestine of unknown etiology. The pathogenesis is hypothesized that the mucosal immune system shows an aberrant response towards luminal antigens such as dietary factors and commensal microbiota in genetically susceptible individuals.
