Résumé
Nigrostriatal dopaminergic denervation (NSDD) remains poorly characterized in cerebellar multiple system atrophy (MSA-C). We aimed to study NSDD progression in MSA-C and evaluate the capacity for [123I]-FP-CIT-SPECT and parkinsonism to differentiate MSA-C from idiopathic late-onset cerebellar ataxia (ILOCA). We included 85 patients successively referred for sporadic late-onset cerebellar ataxia (SLOCA). Every 6 months, SARA, UPDRS-III, and SDFS scores were measured, and MSA-C diagnostic criteria were searched for. Striatal/occipital dopaminergic binding ratio was evaluated every year with [123I]-FP-CIT-scintigraphy. After a mean follow-up of 33.8 months, 33 patients had probable MSA-C, 8 possible MSA-C, and 44 ILOCA. SARA and UPDRS-III scores worsened faster in the probable MSA-C group ( Rapid symptom worsening and NSDD existence and progression predict MSA-C among patients with SLOCA. Parkinsonism, NSDD, and dysautonomia should be considered equivalent for possible MSA-C diagnosis.
