Study Notes
What is ALS?
- Amyotrophic lateral sclerosis (ALS) is a progressive neurological disease that affects nerve cells in the brain and spinal cord.
- Also known as Lou Gehrig's disease, after the famous baseball player who was diagnosed with the condition.
Causes and Risk Factors
- The exact cause of ALS is unknown, but genetics, environment, and lifestyle factors may contribute to its development.
- 5-10% of ALS cases are inherited, while the remaining 90-95% are sporadic, with no clear cause.
- Risk factors include:
- Age: ALS typically affects people between 40-70 years old.
- Sex: Men are more likely to develop ALS than women.
- Family history: Having a family member with ALS increases the risk.
- Military service: Some studies suggest a higher risk of ALS in military veterans.
Symptoms
- Initial symptoms may be subtle and can include:
- Muscle weakness or twitching
- Muscle cramps
- Twitching or cramping of the muscles, especially in the arms and legs
- Weakness or fatigue in the arms and legs
- Difficulty speaking, swallowing, or breathing
- As the disease progresses, symptoms can spread to other parts of the body, leading to:
- paralysis of the arms and legs
- Difficulty with speech, swallowing, and breathing
- Cognitive and behavioral changes
Diagnosis
- There is no single test for ALS, and diagnosis is typically made through a combination of:
- Medical history and physical examination
- Electromyography (EMG) to measure muscle activity
- Nerve conduction studies (NCS) to measure nerve function
- Imaging tests (e.g., MRI, CT scans) to rule out other conditions
- Blood tests to rule out other diseases
Treatment and Management
- There is no cure for ALS, but treatment focuses on managing symptoms and improving quality of life.
- Medications can help:
- Slow disease progression
- Relieve symptoms such as muscle cramps and stiffness
- Improve breathing and nutrition
- Other therapies include:
- Physical therapy to maintain mobility and strength
- Speech therapy to improve communication
- Occupational therapy to assist with daily activities
- Respiratory therapy to support breathing
Prognosis
- ALS is a progressive disease, and symptoms worsen over time.
- The average life expectancy after diagnosis is 2-5 years, but some people may live for 10 years or more.
- The rate of progression varies widely between individuals.
