Muscle & nerve·2025

This case study details amyotrophic lateral sclerosis (ALS), a rare motor neuron disease. It highlights the progressive muscle weakness and atrophy characteristic of ALS, impacting diagnosis and pathology.

Area of Science:

  • Neurology
  • Pathology

Background:

  • Amyotrophic lateral sclerosis (ALS) is a rare, fatal neurodegenerative disorder affecting motor neurons.
  • It leads to progressive muscle weakness, atrophy, and spasticity, with an average survival of 3-4 years.

Observation:

  • This case study presents a woman with ALS, detailing her symptoms, neurological examination, and pathological findings.
  • The patient exhibited progressive weakness and muscle atrophy starting in the hand and spreading to contiguous muscle segments.
  • Key spared functions included cognition, extraocular muscles, and urinary sphincters, with respiratory muscle weakness appearing late.

Findings:

  • Definitive clinical diagnosis requires evidence of both upper and lower motor neuron disease.
  • Pathology revealed degeneration of lateral corticospinal tracts, motor neuron loss, astrogliosis in the brain and brain stem, and neuronal inclusions.

Implications:

  • Understanding the progression and pathological hallmarks of ALS is crucial for diagnosis and management.
  • This case contributes to the understanding of ALS symptom presentation and disease course.
