Takeaway
When applied together, assessments of ocular motor control and apraxia can discriminate between corticobasal syndrome (CBS), progressive supranuclear palsy (PSP) and multiple system atrophy (MSA).
Why this matters
This study produced highly sensitive and specific differential diagnosis criteria between atypical Parkinsonism syndromes, without requiring elaborate or expensive analyses, which may assist in earlier diagnosis and tailored disease treatment.
