Lou Gehrig’s disease, medically known as amyotrophic lateral sclerosis (ALS), is a progressive neurological condition that affects the nerve cells responsible for voluntary muscle movement.
The disease can begin gradually, and the earliest symptoms may initially seem like ordinary weakness, clumsiness or muscle problems. Recognizing persistent changes can help someone seek an appropriate medical evaluation sooner. Mayo Clinic
What Is Lou Gehrig’s Disease?
ALS affects motor neurons in the brain and spinal cord. As these nerve cells become damaged, the muscles they control gradually become weaker.
The condition is called Lou Gehrig’s disease because the famous baseball player Lou Gehrig was diagnosed with ALS.
ALS is relatively uncommon, and having one of these symptoms does not mean a person has ALS. Several much more common conditions can cause muscle weakness, cramps, twitching or difficulty walking.
Early Symptoms of ALS
Early symptoms can vary considerably depending on which muscles are affected first. Some of the commonly reported early signs include:
1. Weakness in One Hand
A person may suddenly find it harder to grip objects, turn keys, open containers or perform tasks requiring fine hand movements.
Hand weakness or clumsiness can be an early feature of ALS. Mayo Clinic
2. Frequent Tripping or Falling
Weakness in the legs, feet or ankles can make walking more difficult. Someone might begin tripping more frequently or have trouble with activities that were previously easy.
3. Muscle Twitching
Small involuntary muscle movements, called fasciculations, can occur in ALS. They may appear in the arms, shoulders, legs or tongue.
However, muscle twitching by itself is not enough to indicate ALS and can occur for many other reasons. NINDS
4. Muscle Cramps or Stiffness
Some people develop persistent muscle cramps or stiffness along with progressive weakness.
The combination of symptoms and their progression is much more important than an isolated cramp.
5. Changes in Speech
ALS can sometimes initially affect the muscles used for speaking. Speech may become slower, weaker or slurred.
6. Difficulty Swallowing
Some people develop difficulty swallowing food or liquids. This can occur when the muscles involved in swallowing become affected. Mayo Clinic
7. Difficulty Performing Everyday Activities
Tasks such as dressing, writing, walking, climbing stairs or handling utensils may gradually become more difficult when muscle weakness progresses.
Why Early Symptoms Can Be Confusing
One of the challenges with ALS is that its early symptoms can resemble those of other neurological, muscular or orthopedic conditions.
For example, weakness, cramps or difficulty walking can have many different causes. There is no single symptom that can confirm ALS.
Doctors generally use a neurological examination and several tests to evaluate persistent symptoms and rule out other conditions. Tests may include electromyography (EMG) and nerve-conduction studies. Mayo Clinic
When Should You See a Doctor?
Persistent or progressively worsening muscle weakness, repeated falls, hand clumsiness, difficulty speaking or difficulty swallowing should be discussed with a healthcare professional.
This is particularly important when symptoms continue to worsen rather than improving.
A doctor may refer someone to a neurologist if a neurological condition needs to be investigated.
One Important Point About the Image
The photograph accompanying this viral claim cannot diagnose ALS.
A person’s hand, leg or knee can look unusual for many different reasons, and an image alone cannot determine whether someone has a neurological disease. Diagnosis requires a medical history, physical and neurological examination and, when appropriate, additional testing. Mayo Clinic
The Bottom Line
Lou Gehrig’s disease (ALS) can begin with subtle changes such as progressive muscle weakness, hand clumsiness, frequent tripping, muscle twitching or cramps, slurred speech, or difficulty swallowing.
But these symptoms have many possible causes, so experiencing one of them does not automatically mean someone has ALS.
If weakness or other neurological symptoms are persistent or progressively getting worse, getting evaluated by a healthcare professional is the safest approach.
