Amyotrophic lateral sclerosis. Clinical features and prognosis

Area of Science:

• Neurology
• Clinical Medicine
• Epidemiology

Background:

• Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease.
• Understanding ALS demographics and prognostic factors is crucial for patient care.

Purpose of the Study:

• To analyze the clinical characteristics and survival rates of amyotrophic lateral sclerosis patients.
• To investigate the influence of age and onset type on ALS prognosis.

Main Methods:

• Retrospective analysis of 668 patients diagnosed with amyotrophic lateral sclerosis.
• Follow-up periods extended up to three years.
• Comparison of survival rates based on age at diagnosis and mode of onset (spinal vs. bulbar).

Main Results:

• Amyotrophic lateral sclerosis (ALS) diagnosis was identified in 668 patients.
• The five-year survival rate for all patients was 39.4%.
• Younger patients (<50 years) and those with spinal-onset ALS demonstrated significantly better prognoses compared to older patients and those with bulbar-onset ALS.

Conclusions:

• Amyotrophic lateral sclerosis (ALS) is more prevalent in women than previously reported.
• Age at diagnosis and mode of onset are critical prognostic indicators for ALS survival.
• Further research into sex-based differences and specific ALS subtypes is warranted.
