Patients with essential tremor (ET) had gut dysbiosis, which was associated with clinical features such as measures of disease severity, emotion, and cognition.
Why this matters
ET is a common movement disorder that clinically overlaps with Parkinson’s disease (PD). Dysfunction to the gut microbiota is linked to the pathogenesis of PD.
Examining the gut microbiota may assist with understanding the pathogenesis of ET and help distinguish ET from PD for diagnosis purposes.
