Symptoms
By Mayo Clinic staffEarly signs and symptoms of ALS include:
- Difficulty lifting the front part of your foot and toes (footdrop)
- Weakness in your leg, feet or ankles
- Hand weakness or clumsiness
- Slurring of speech or trouble swallowing
- Muscle cramps and twitching in your arms, shoulders and tongue
The disease frequently begins in your hands, feet or limbs, and then spreads to other parts of your body. As the disease advances, your muscles become progressively weaker until they're paralyzed. It eventually affects chewing, swallowing, speaking and breathing.
