    • Chapter 12- Nervous System Suffixes and ALS Jenny Trace
    • Suffixes
      • -paresis: weakness
      • -taxia: muscle coordination
      • For this presentation I’m going to report on Amyotrophic lateral sclerosis (ALS) and how those suffixes are used to describe this disease.
    • Amyotrophic lateral sclerosis (ALS)
      • Also known as Lou Gehrig’s disease
      • A motor neuron disease that attacks nerve cells that control voluntary movement.
      • ALS affects approximately 5 out of every 100,000 people worldwide
      • Higher prevalence in males than females
      • Usually affects people 50 and older, but can occur in younger people
      Picture of Lou Gehrig
    • How Does ALS Work?
      • Motor neurons are communication unit between brain, brain stem, and spinal cord and voluntary muscles
      • Both upper motor neurons (brain) and lower motor neurons (spinal cord) are affected
      • With ALS, motor neurons degenerate and die and are not able to send messages to muscles
      • This causes loss of function and the muscles weaken and waste away
      • As the disease progresses, the brain loses all capacity to control voluntary muscles
      • When the muscles control of the diaphragm is lost , then the patient is no longer to breath on his/her own
      • Patients usually die within 3-5 years from respiratory failure.
    • Early Symptoms
      • Usually mild and go unnoticed by doctor
      • Twitching, cramping or stiffness of muscles
        • Usually arm or leg
      • Slurred or nasal speech
      • Difficulty chewing or swallowing
    • Symptoms
      • As symptoms persist, then diagnosis for ALS is usually given
      • Difficulty breathing (dysphagia)
      • Difficulty speaking or forming words
      • Muscle atrophy
      • Exaggerated reflexes
      • Overactive gag reflex
      • Difficulty swallowing
      • Paralysis
    • Prevalence of ALS Symptoms
    • Ataxia
      • Lack of muscle control doing voluntary movements
        • Walking, picking up items, speech, swallowing
      • People with ALS first show signs of ataxia early on and it increases as the disease progresses
    • Quadriparesis
      • Muscle weakness affecting all four limbs
      • Depending on how the ALS is progressing, a patient may first experience paraparesis (weakness of lower limbs) or weakness of all limbs
      • This will eventually result in paralysis and the patient can become a quadriplegic
    • In loving memory of my grandfather, Jim Dooley, who suffered from ALS.
