Amyotrophic Lateral Sclerosis (ALS)/Lou Gehrig's Disease

What is ALS?

Amyotrophic lateral sclerosis (ALS), commonly known as Lou Gehrig’s disease, is a rapidly progressive, neurological disease that affects the nerve cells in the brain (upper motor neurons) and spinal cord (lower motor neurons) that control voluntary muscle movement. Motor neurons begin to degenerate and stop sending messages to muscles. With ALS, muscles gradually waste away and the brain is unable to initiate and control voluntary movements like chewing, walking, breathing and talking. Symptoms get worse over time and some individuals eventually can't breathe on their own. Most cases of ALS happen with no known cause, while a small percentage of cases are inherited. Currently, there is no cure for ALS.
 
 
Risk factors
 
  • Heredity
  • Gene mutations
  • Smoking
  • Military service
 
 
Diagnosis is difficult early on because ALS may mimic several other neurological diseases. Tests to rule out other conditions may include:
 
  • Electromyogram (EMG)
  • Nerve conduction study
  • Magnetic resonance imaging (MRI)
  • Blood and urine tests
  • Spinal tap
  • Muscle biopsy
 
 
Treatments can’t reverse the damage of ALS, but they can slow the progression of symptoms, prevent complications and make you more comfortable and independent. There is no cure for ALS, and eventually the disease is fatal. 
 
 
 
# ALS BY THE NUMBERS #
 
  • ALS affects about 30,000 Americans and 5,000 new cases are diagnosed each year.
  • Occurs throughout the world with no racial, ethnic or socioeconomic boundaries.
  • 5-10% of all ALS cases are familial.
  • Military veterans are 1.5- 2 times more likely to develop ALS.
  • Most common in people 45-60 years old. 
  • Responsible for 5 of every 100,000 deaths in people aged 20 or older.
