Abstract
While the onset of a dominantly inherited ataxia is typically taken to be the onset of gait ataxia a wide range of other symptoms related to central and/or peripheral nervous system impairment or even to nonneurological involvement can be the presenting feature Knowledge of these is fairly robust for the commonest spinocerebellar ataxias SCAs 1 2 3 and 6 and for those where a striking nonataxic presentation is the norm SCAs 7 and 12 but the literature is potentially misleading in the rarer dominant ataxias This review summarises what is currently known of these nonataxic presentations and outlines and explains the difficulties associated with determining nonataxic presentations of dominant ataxias The relevant literature was surveyed including systematic reviews where available and case reports Nonataxic presentations of dominant ataxias are classified by symptom
