Lou Gehrig’s Disease: Here Are Some Early Symptoms to Know
Lou Gehrig’s disease, medically known as amyotrophic lateral sclerosis (ALS), is a progressive neurological disease that damages motor neurons—the nerve cells responsible for controlling voluntary muscle movement. (NINDS)
The earliest symptoms can be subtle and vary considerably from person to person.
⚠️ Common early symptoms
- Muscle weakness: Often begins in one hand, arm, leg, foot, or sometimes the neck.
- Muscle twitching: Small involuntary muscle movements, called fasciculations, may occur in the arms, legs, shoulders, or tongue.
- Muscle cramps: Persistent or recurrent cramps can occur alongside weakness or twitching.
- Clumsiness: Difficulty buttoning clothes, writing, turning a key, gripping objects, or performing other fine-motor tasks can sometimes be an early sign.
- Tripping or difficulty walking: Weakness in the legs or feet may cause stumbling, falls, or difficulty with stairs.
- Stiff or tight muscles: Muscle stiffness and involuntary spasms can develop.
- Slurred or nasal speech: In some people, ALS initially affects the muscles involved in speaking.
- Difficulty chewing or swallowing: This can occur when the disease first affects the muscles of the mouth and throat. (NINDS)
Important: these symptoms don’t automatically mean ALS
Muscle twitching, cramps, weakness, or difficulty walking can have many other causes, and ALS can be difficult to diagnose in its early stages because its symptoms overlap with other neurological and medical conditions. Diagnosis requires a medical evaluation and may involve neurological examination, electromyography (EMG), nerve-conduction studies, and tests to rule out other conditions. (Mayo Clinic)
If someone develops progressive, unexplained muscle weakness, particularly when it is accompanied by persistent twitching, muscle wasting, speech changes, or swallowing difficulties, they should arrange an evaluation with a healthcare professional or neurologist.
The key point: An isolated muscle twitch or occasional cramp is not enough to indicate ALS. What is more concerning is progressive weakness and loss of muscle function over time. (Mayo Clinic)
