Lou Gehrig’s Disease (ALS): Here Are the First Symptoms to Know
Lou Gehrig’s disease, also known as amyotrophic lateral sclerosis (ALS), is a progressive neurological disease that affects nerve cells responsible for controlling voluntary muscle movement. Over time, ALS can lead to increasing muscle weakness and difficulty with movement, speech, swallowing, and breathing.
Early symptoms can be subtle and may vary from person to person.
1. Muscle weakness in an arm, leg, hand, or foot
One of the earliest signs may be weakness in a specific area, such as:
- Dropping objects more often
- Difficulty buttoning clothes
- Trouble walking or climbing stairs
- A foot that “drags” while walking
2. Muscle twitching (fasciculations)
Small, involuntary muscle twitches may occur, often in:
- The arms
- Legs
- Shoulders
- Tongue
Muscle twitching alone is common and does not necessarily mean ALS, but it can be a symptom when combined with weakness.
3. Muscle cramps and stiffness
Some people experience:
- Frequent muscle cramps
- Tight or stiff muscles
- Increased difficulty with coordination
4. Changes in speech
ALS can affect muscles used for speaking, causing:
- Slurred speech
- A softer voice
- Difficulty pronouncing certain words
5. Trouble swallowing
Early swallowing difficulties may include:
- Coughing while eating or drinking
- Food feeling stuck
- Changes in eating habits
6. Loss of coordination and balance
Some people notice:
- More frequent tripping
- Clumsiness
- Difficulty with fine movements
7. Unexplained muscle loss
As affected muscles weaken, they may become smaller due to loss of muscle tissue.
8. Fatigue and reduced endurance
People may notice they tire more easily during activities that used to feel normal
