Amyotrophic lateral sclerosis (ALS), often called Lou Gehrig’s disease, is a rare but serious neurological disorder that gradually damages the nerve cells responsible for controlling voluntary muscles. As these motor neurons deteriorate, the muscles weaken, making everyday activities increasingly difficult.
Although there is currently no cure for ALS, recognizing the early symptoms can lead to earlier diagnosis, better symptom management, and access to specialized care and support.
Here’s what you should know about the early warning signs of ALS.
What Is ALS?
ALS is a progressive neurodegenerative disease that affects motor neurons—the nerve cells that send signals from the brain and spinal cord to muscles throughout the body.
As these nerve cells die, muscles gradually lose their ability to function, leading to:
- Muscle weakness
- Muscle wasting (atrophy)
- Difficulty moving
- Problems speaking and swallowing
- Breathing difficulties in later stages
Importantly, ALS does not typically affect intelligence, memory, hearing, vision, taste, or touch. Most people remain mentally alert throughout the disease.
1. Muscle Weakness
One of the earliest signs is weakness that develops gradually.
People may notice:
- Difficulty lifting objects
- Trouble climbing stairs
- Weak grip strength
- One leg feeling weaker than the other
The weakness often starts in one area before spreading.
2. Frequent Muscle Twitching (Fasciculations)
Small involuntary muscle twitches are common in ALS.
They may occur in:
- Arms
- Legs
- Shoulders
- Tongue
- Hands
It’s important to remember that muscle twitching alone is very common and is usually caused by harmless conditions such as stress, fatigue, caffeine, or exercise—not ALS.
