| Popis: | Objective: This retrospective study analyzed the clinical characteristics and prognosis of the elderly amyotrophic lateral sclerosis (ALS) population in a large sample. Methods: The study included 1,005 patients with sporadic ALS admitted to Chinese PLA General Hospital between March 2011 and March 2021. We stratified the ALS patients into young and old groups using 2 cutoffs for the age at disease onset (≥65 or ≥70 years old) and compared their demographic, clinical, and survival data. Results: The mean onset age of all patients was 52.79 ± 10.55 years, with 123 (12.24%) having a disease onset ≥65 years and 44 (4.38%) having an onset ≥70 years. There were 624 (62.1%) male patients. More bulbar-onset cases were in the late-onset group (p = 0.001). The sex distribution, time from onset to diagnosis, and the time of symptom spread from spinal or bulbar localization to a generalized localization did not differ between groups. Late-onset patients progressed more rapidly and had a significantly shorter survival. Conclusions: Chinese ALS patients have an earlier age at onset and a relatively smaller proportion of old onset than European and Japanese patients. Elderly patients are more likely to have bulbar onset, which is related to rapid progression and a shorter survival. |
