What is Amyotrophic Lateral Sclerosis?
Amyotrophic lateral sclerosis (ALS) is a serious condition that affects the nerves responsible for muscle movement. Over time, these nerve cells break down, making it harder to control muscles used for walking, speaking, swallowing, and breathing.
ALS is sometimes called Lou Gehrig’s disease. While it affects movement, it usually does not impact thinking, vision, or hearing.
The exact cause of ALS is not fully understood. Most cases happen without a known reason. In some people, inherited genetic changes play a role. ALS is more commonly diagnosed in adults between the ages of 40 and 70, but it can occur earlier.
Symptoms
ALS symptoms often begin gradually and worsen over time. Early signs may be easy to overlook.
Common symptoms include:
- Weakness in the arms or legs
- Muscle twitching or cramping
- Trouble with coordination or balance
- Slurred speech or difficulty speaking clearly
- Problems swallowing
- Ongoing fatigue
- Emotional changes, such as sudden laughing or crying
As the condition progresses, breathing becomes more difficult, and muscle control continues to decline.
How is it diagnosed?
Diagnosing ALS can take time because its symptoms are similar to other conditions. There is no single test that confirms ALS.
Your provider will start with a detailed medical history and physical exam. Additional testing may include:
- Blood and urine tests
- Electromyography (EMG) to assess muscle activity
- Nerve conduction studies to evaluate nerve signals
- MRI scans to look for other causes of symptoms
In some cases, further testing, such as a spinal tap or muscle biopsy, may be recommended to rule out other conditions.
How is it treated?
There is currently no cure for ALS, but treatment focuses on slowing the disease and improving quality of life.
Early care often includes:
- Medications that may help slow progression
- Physical therapy to maintain movement and strength
- Occupational therapy to support daily activities
- Speech therapy for communication and swallowing
As the condition advances, additional support may be needed, such as:
- Breathing support or ventilators
- Nutritional support, including feeding tubes
- Mobility aids like wheelchairs
Each person’s experience with ALS is different. Care plans are tailored to help maintain comfort, independence, and dignity for as long as possible.
