Neurological Disease

Amyotrophic Lateral Sclerosis (ALS)

HIGH SEVERITY

A progressive neurodegenerative disease affecting upper and lower motor neurons, leading to muscle weakness, atrophy, spasticity, and ultimately respiratory failure. Average survival 3-5 years from symptom onset. No cure.

Diagnostic Methods

  • 1Neurological examination
  • 2MRI/CT imaging
  • 3EEG
  • 4EMG/NCV
  • 5Lumbar puncture
  • 6Genetic testing
  • 7Neuropsychological testing

Prognosis

Median survival is 3-5 years from symptom onset. 10% survive >10 years (slow progressors). Respiratory failure is the primary cause of death. Riluzole extends survival by 2-3 months. Non-invasive ventilation (BiPAP) extends survival by 12-18 months when started at appropriate time. Gastrostomy feeding prevents malnutrition. Early multidisciplinary care improves quality of life and survival. Bulbar onset has worse prognosis (2-3 years) than limb onset (3-5 years).

Prevention

  • Head protection
  • Cardiovascular health
  • Cognitive stimulation
  • Physical exercise
  • Healthy diet
  • Avoidance of toxins
  • Regular monitoring

Research Status

Riluzole, edaravone, tofersen (SOD1), and tofersen modestly slow progression. Non-invasive ventilation extends survival. Multidisciplinary care essential. Tofersen for SOD1-ALS. AMX0035 (Relyvrio) withdrawn. Stem cell trials ongoing.
