Abstract

Georg Thieme Verlag KG Stuttgart · New York. Phosphomannomutase deficiency (PMM2-CDG) causes a cerebellar syndrome that has been evaluated using the International Cooperative Ataxia Rating Scale (ICARS). However, no particular dysarthria tests have been used. Speech ICARS subscore subjectively assesses fluency and clarity of speech with two items. Repetition of syllables, traditionally used for characterization of ataxic speech, was validated in early-onset ataxia conditions. We assess the validity of the PATA test (SCA Functional Index [SCAFI]) in PMM2-CDG patients.PATA rates from 20 patients were compared with a control population were and correlated with ICARS and neuroimaging.There was a difference between the PATA rate in patients and controls. PATA rate increased with age in controls. In patients, the improvement of PATA rate with age was not significant. In patients, the PATA rate was negatively correlated with the total ICARS score and the Speech ICARS subscore. Regarding neuroimaging, midsaggital vermis relative diameter was positively correlated with PATA results. These last differences were also significant when the results are corrected by age.PATA rate provides an easy measure for a quantitative assessment of dysarthria that may help clinicians to monitor patients' evolution in a regular consultation. It could also be used in PMM2-CDG clinical trials implementing ICARS speech subscore information.
