Lou Gehrig’s Disease: What Are the First Symptoms?
Lou Gehrig’s disease is another name for amyotrophic lateral sclerosis (ALS), a progressive neurological disease that damages motor neurons—the nerve cells responsible for controlling voluntary muscles.

Early symptoms can be subtle and vary from person to person. Common possibilities include:
Muscle weakness, often beginning in one hand, arm, foot, or leg.
Hand clumsiness—difficulty buttoning clothes, gripping objects, or performing familiar tasks.
Tripping or falling because of weakness in the feet or legs.
Muscle twitching (fasciculations), sometimes accompanied by cramps.
Muscle stiffness or tightness.
Slurred speech or difficulty controlling the muscles used for speaking.
Difficulty swallowing or chewing.
Muscle wasting in an affected area as weakness progresses.
Less commonly, changes in thinking or behavior can occur.

Important: these symptoms don’t automatically mean ALS
Many much more common conditions can cause muscle twitching, cramps, weakness, numbness, or difficulty walking. ALS can be difficult to diagnose early, and doctors use neurological examinations and tests such as EMG and imaging to help distinguish it from other disorders.

If you have progressive, unexplained muscle weakness, particularly if it’s affecting one limb or progressively interfering with walking, gripping, speaking, or swallowing, arrange an evaluation with a doctor or neurologist.
Bottom line: The most characteristic early clue is progressive muscle weakness, sometimes accompanied by twitching, cramps, stiffness, or speech/swallowing problems—not simply occasional muscle twitching by itself.
