What is ALS?
ALS is a disease that gradually takes away a person's ability to move, speak, and breathe — while leaving the mind sharp and aware. Understanding it is the first step toward showing up for the families who live with it.
A progressive disease of the motor neurons
ALS stands for amyotrophic lateral sclerosis. It is often called Lou Gehrig's disease, after the famous baseball player whose diagnosis brought it into the public eye.
ALS attacks the motor neurons — the nerve cells in the brain and spinal cord that control voluntary muscle movement. As these neurons break down and die, the brain can no longer send signals to the muscles. Over time, the muscles weaken and waste away.
For most people, the mind and senses remain clear, even as the body becomes harder to control. That reality is part of what makes ALS so difficult — and why compassionate support matters so much.
How ALS affects the body
ALS affects everyone differently, and it progresses at its own pace. Common changes over time include:
Muscle weakness
Weakness or stiffness, often starting in the hands, arms, legs, or feet, that gradually spreads.
Changes in speech
Slurred or quieter speech as the muscles used to talk become harder to control.
Difficulty swallowing
Trouble eating and drinking, which can affect nutrition and daily routines.
Breathing changes
As respiratory muscles weaken, breathing may require support over time.
A clear mind
For most people, thinking, memory, and the senses remain largely intact throughout.
A personal journey
Symptoms, timing, and progression vary widely from one person to the next.

A few things worth understanding
Anyone
ALS can affect adults of any background. It is most often diagnosed between the ages of 40 and 70, but it does not discriminate.
No cure*
There is currently no cure, but treatments, therapies, and dedicated care can help manage symptoms and improve quality of life.
Hope
Research is advancing, and communities like ours surround families with care — proof that no one has to face ALS alone.
