Parkinson's disease subtypes
Groups of people with Parkinson's disease who share a pattern of symptoms, progression rate or underlying biology, used to tailor care and research.
Parkinson's disease is not one uniform condition. Two people with the same diagnosis can differ widely in their dominant symptoms (tremor versus postural instability and gait difficulty), the speed of progression, the presence of cognitive or mood symptoms, and their response to medication. Subtyping is the attempt to describe these groups systematically.
Historically subtypes were defined by clinicians from motor presentation. Data-driven subtyping instead uses clustering and related methods on clinical, behavioural and biological data to find groups that are stable, clinically meaningful and ideally predictive of progression. Reliable subtypes can improve prognosis conversations, help match patients to the right care pathway, and make clinical trials more efficient by enrolling the people most likely to respond.
Why it matters to our work
Identifying clinically meaningful subtypes and reference phenotypes — and predicting which one a patient belongs to — is a core goal of our neuroanalytics research.
