title: Current treatment pathways in ALS: a South American perspective.
abstract: This article presents the findings relating to the South American subgroup of 60 patients in an international survey of the current diagnosis and treatment of patients with amyotrophic lateral sclerosis (ALS). The mean time between first symptoms and first consultation with a physician was 3.7 months, and mean delay in seeing a neurologist was then 5.6 months, giving a mean time from symptom onset to confirmation of diagnosis of 16.6 months. The time to confirmation of diagnosis was much longer for patients with symptoms of limb onset (17.5 months) than for those with bulbar onset (10.0 months). Cases with symptoms of upper-limb onset were diagnosed more rapidly (14.9 months) than those with symptoms of lower-limb onset (21.8 months). The diagnosis was confirmed in 48% of cases within 15 months of symptom onset, and a further 27% were diagnosed within 15-24 months; 47% of cases were confirmed within 4 months of consulation with a neurologist and a further 17% within 4-6 months. The first physician seen was the general practitioner in 47% of cases overall. When the neurologist was the first physician seen (27% of patients in Brazil, 0% in Argentina), diagnosis was achieved within 14 months in 88% of cases. EMG was performed in almost all patients. MRI and CT were widely used, which may cause delays. Announcement of the diagnosis was made immediately to 75% of patients overall. Riluzole was prescribed for 23% of patients in Brazil and for 67% of patients in Argentina.
