Area of Science:

  • Neurology
  • Epidemiology
  • Pathogenesis research

Background:

  • Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease.
  • The multistep model of pathogenesis suggests a series of molecular events leading to disease onset.
  • Understanding disease progression is crucial for developing effective treatments.

Purpose of the Study:

  • To investigate the applicability of the multistep pathogenesis model to amyotrophic lateral sclerosis (ALS) in a Malaysian population.
  • To analyze clinical data from a multiethnic Malaysian ALS patient registry.
  • To compare findings with international ALS cohorts.

Main Methods:

  • Data collection from 289 Malaysian ALS patients (2016-2024).
  • Inclusion of clinical data, specifically age at symptom onset.
  • Construction of a least squares linear regression model using log-transformed incidence and age data.
  • Approximation of population incidence adjusted for age-specific population demographics.

Main Results:

  • A significant linear relationship was observed between the logarithm of incidence and the logarithm of age (r=0.93).
  • The calculated slope of 4.57 (95% CI, 3.3-5.8) supports a multistep disease process.
  • Findings suggest a 6-step progression model for ALS.

Conclusions:

  • The progression of amyotrophic lateral sclerosis (ALS) in Malaysian patients aligns with the established multistep model of pathogenesis.
  • This study validates the multistep model in a multiethnic Asian cohort.
  • Results indicate a conserved disease mechanism across diverse populations.
