Structure and function of the cerebellum: Our lab focuses on structural and functional topography in the human cerebellum in health and disease, using MRI techniques.
Outcome measures in ataxia: We quantify ataxia using the Brief Ataxia Rating Scale (BARS) together with machine learning to develop observer independent, quantitative, real time analysis of motor control in patients with ataxia and other movement disorders. We use the cerebellar cognitive affective / Schmahmann syndrome scale to detect and quantitate the degree of cognitive and emotional impact in patients with cerebellar diseases; the Patient Reported Outcome Measure for Ataxia (PROM-Ataxia) to capture patient experience, and we are developing a CCAS pediatric scale, a pediatric BARS, and refining the cerebellar neuropsychiatric rating scale.
Natural History studies and clinical trials in ataxia: We are engaged in the National Ataxia Foundation (NAF) and clinical research consortium for the study of cerebellar ataxia (CRC-SCA) natural history study, the NIH-sponsored READISCA study and MRI study of MRI spectroscopy in spinocerebellar ataxia, and the ESMI study - European collaborative investigation of spinocerebellar ataxia type 3; we are a lead clinical site for Biohaven’s troriluzole study in SCA 1, 2, 3, and 6; Biohaven’s verdiperstat study in multiple system atrophy; and about to start Biogen’s ASO study in SCA3.
