ALS (amyotrophic lateral sclerosis), also known as Lou Gehrig’s disease, is a progressive condition that affects the nerve cells (motor neurons) that control voluntary movement. As these motor neurons stop working, the brain gradually loses its ability to communicate with muscles, impacting walking, speaking, swallowing, and breathing.
Every ALS journey is personal. But families often share a common experience: things change quickly, decisions feel heavy, and clear guidance can be hard to find. This article is meant to be a steady starting point.
What ALS affects (and what it doesn’t)
ALS mainly affects movement. People may notice:
- Weakness in an arm or leg
- Muscle twitching or cramping
- Changes in speech, voice, or swallowing
- Fatigue, stiffness, or balance issues
- Shortness of breath as breathing muscles weaken over time
Some people also experience changes in thinking or behavior, while many do not. Anxiety, grief, and uncertainty are very common—and completely understandable.
Why early support matters
Even without a cure yet, early support can make a meaningful difference. A multidisciplinary team: neurology, speech/swallowing specialists, respiratory support, physical/occupational therapy, nutrition, and social work—helps families plan ahead so decisions don’t feel rushed later.
Why research matters
ALS research is not abstract. It’s the path to:
- Earlier and more accurate diagnosis
- Better symptom management
- Stronger clinical trials
- New treatments that can meaningfully change outcomes
At the ALS Institute of New Jersey, our mission is to advance ALS research and accelerate the work that leads to better answers.
If you believe ALS research deserves urgency, here is a simple way to act.
Donate to ALS Research
Your donation supports research progress and helps move science forward.
If you’re not able to donate right now, sharing this post also matters. It helps more people understand what ALS really takes and why research must answer.
