Description of intervention(s) / exposure
Neurodegenerative disorders cause a collapse of the structure and function of neural networks. In this study sensory, motor, autonomic and cognitive functions are observed. The non-invasive neurological (gait and balance assessments), cognitive (tests for processing speed, attention and working memory), swallowing (a clinical assessment of dysphagia) vestibular (assessment of inner ear balance by observing eye movements) and Nerve Excitability Study (tests conductivity and electrical activity of the nerves) will be administered by suitably trained members of the research team. Observation occurs at Baseline, 3 months, 6 months and 12 months in Year 1, then yearly onwards until the participant has impaired capacity to personally provided informed consent at interim study visits or withdraws from study.

Neurological, cognitive, swallowing and vestibular assessments and a nerve excitability study will take approximately 4 hours (with breaks) on site at St Vincent's Hospital at baseline and yearly afterwards." and "Questionnaires, psychomotor and speech assessments using web based tools will take approximately 45 mins at participants home

Comparator / control treatment
The healthy cohort are a spouse or friend aged 18 years or over, of consenting patient participants who have capacity to personally consent, understands spoken or written English, has ability to travel to research site and is computer literate and has access to a computer/tablet/smart phone. The observational assessments on the healthy cohort include: non-invasive neurological (gait and balance assessments), cognitive (tests for processing speed, attention and working memory), swallowing (a clinical assessment of dysphagia) vestibular (assessment of inner ear balance by observing eye movements) and Nerve Excitability Study (tests conductivity and electrical activity of the nerves) will be administered by suitably trained members of the research team.

Summary
Brief summary
This project seeks to undertake a prospective longitudinal natural history study to generate a comprehensive phenotypic profile of biological, behavioural, clinical, neurocognitive and neurophysiological markers associated with INDD and its progression; and correlate with the genotype when clinically available. This work will provide more complete neurobiological descriptions, novel mechanistic insights, and clear recommendations regarding candidate biomarkers for diagnosis and treatment tracking.
