Lou Gehrig’s Disease: Early Symptoms to Know
Lou Gehrig’s disease, also called amyotrophic lateral sclerosis (ALS), is a progressive neurological disease that damages motor neurons—the nerve cells responsible for voluntary muscle movement.
The early symptoms can be subtle and vary considerably from person to person. They may include:
- Muscle weakness — often beginning in one hand, arm, leg, or the muscles used for speaking.
- Muscle twitching (fasciculations) — small, involuntary movements, commonly noticed in the arms, legs, shoulders, or tongue.
- Muscle cramps — recurring or unusual cramps can occur alongside weakness.
- Dropping objects or difficulty with fine movements — such as buttoning clothes, writing, or turning keys.
- Difficulty walking or frequent tripping — particularly when weakness begins in the legs.
- Slurred or slowed speech — when muscles involved in speaking are affected.
- Difficulty swallowing — coughing while eating or difficulty handling food or liquids can occur in some forms of ALS.
- Stiff or tight muscles (spasticity) — muscles may become unusually stiff and movements less coordinated.
Important: these symptoms don’t automatically mean ALS
Muscle twitching, cramps, weakness, and difficulty walking have many possible causes, including nerve compression, medication effects, vitamin deficiencies, thyroid disorders, and other neurological conditions. ALS is relatively uncommon and cannot be diagnosed from symptoms alone.
A neurologist may use a neurological examination, EMG/nerve-conduction testing, imaging, blood tests, and other investigations to determine the cause.
If someone develops progressive muscle weakness, especially weakness that is steadily worsening or accompanied by speech or swallowing difficulties, they should arrange a medical evaluation rather than assuming it is ALS.
