Early-stage amyotrophic lateral sclerosis symptoms

The first amyotrophic lateral sclerosis symptoms can be so mild they’re barely noticeable. Usually, the first sign is muscle weakness. You might have trouble performing fine movements requiring muscle strength, like grasping a pen, or picking a book up off a shelf.

Some people first experience muscle weakness in a single limb — an arm or a leg. This is called “limb onset” ALS.

The muscles also twitch as signals from motor neurons are disrupted — just as a radio station pops in and out when its signal weakens. Muscle twitches are called fasciculations. They’re not painful, but they can be annoying and interrupt sleep.

Muscle cramping is also common, and the spasms can be painful.

Other early ALS symptoms include:

  • Dropping things
  • Tripping
  • Fatigue
  • Weakness in the arms and legs
  • Slurred speech
  • Poor balance

Early ALS symptoms may occur in only one part of your body — such as in an arm or leg. The effects gradually spread from one part of your body to another.
