Table of Contents
Amyotrophic lateral sclerosis (ALS) is a serious disease that affects nerve cells in the brain and spinal cord. It leads to the gradual loss of muscle control, which can make it hard to move, speak, swallow, and breathe. ALS primarily impacts both upper and lower motor neurons, important for sending signals to muscles.
Symptoms
The main signs of ALS include:
- Weakness in the hands, arms, or legs
- Muscle cramps and twitching
- Difficulty speaking or swallowing
- Increased fatigue
As the disease progresses, people with ALS may lose the ability to walk and perform daily activities, requiring help from caregivers.
Causes
The exact cause of ALS is not fully understood. In some cases, it runs in families, while in others, it appears without any clear reason. Researchers are studying various factors that might contribute to the onset of the disease.
Diagnosis
Doctors diagnose ALS through a combination of medical history, physical examinations, and tests to rule out other conditions. There is no single test for ALS, making diagnosis challenging.
Prognosis
The progression of ALS varies from person to person. Some may experience a rapid decline, while others might have a slower progression. Currently, there are no cures, but treatments can help manage symptoms and improve quality of life.
Research
Ongoing studies aim to better understand ALS and find new treatments. Recent research suggests that certain biological processes in cells may be linked to the disease. This knowledge could lead to innovative approaches for managing or treating ALS in the future.
