ALS symptoms
Because ALS is a progressive disease with a gradual onset, the symptoms can be difficult to identify in the early stages. Some patients may experience weakness or shakiness at first; they may experience difficulty when writing or tying their shoelaces. Others may have difficulty speaking or notice a change in their voice.
Over time, patients experience more serious muscle weakness and paralysis, though the rate and pattern of progression will vary from person to person. Common early symptoms include muscle fatigue, cramping, slurred speech, increased clumsiness, or unexplainable bouts of laughing or crying (emotional lability).
As the disease progresses, the breathing muscles will be affected, and patients will eventually require permanent breathing support. The mean survival time for patients living with ALS is 3 to 5 years, though many people can live with the disease for 10 years or longer.
The most common symptoms of ALS include:
- Muscle weakness
- Paralysis
- Fatigue
- Difficulty breathing
