What Is ALS?
ALS, or Amyotrophic Lateral Sclerosis, is a condition that affects the nerves controlling your muscles. Over time, these nerves stop working properly, which causes muscles to become weak and waste away.
ALS usually starts slowly, but it gets worse as muscles lose their strength and control. It can affect movement, speech, and even breathing.
Common Signs and Symptoms of ALS
ALS affects people in different ways, but here are some common signs to watch for:
- Muscle weakness, especially in the hands, arms, legs, or feet
- Muscle twitching or cramps that don’t go away
- Difficulty speaking clearly or swallowing food
- Feeling unusually tired or weak without a clear reason
- Muscle stiffness or tightness
- Trouble with balance or coordination
If you notice several of these symptoms happening together, it’s important to pay attention and consider getting a medical check-up.
What Causes ALS?
Scientists don’t fully understand why ALS happens, but some risk factors are known to increase the chance of developing the condition:
- Genetics: About 10% of ALS cases run in families. If a family member has ALS, there’s a chance the gene can be passed down.
- Age: The risk of ALS rises with age, especially between 55 and 75 years old.
- Sex: More men than women develop ALS before age 65, but after 70, the difference disappears.
- Smoking, especially in women after menopause, may increase the risk.
- Exposure to certain toxins, like lead or chemicals, could play a role, but there is no clear proof of one specific cause.
- Military service has been linked to a higher risk, possibly because of exposure to chemicals, injuries, infections, or intense physical activity.
While these factors may increase risk, ALS often happens without a clear cause, and it cannot be prevented.
How to Diagnose ALS?
Only a doctor or specialist can diagnose ALS. Here's what the process usually involves:
- Physical exam: Checking your muscle strength, reflexes, and coordination.
- Medical history: Talking about your symptoms, when they started, and how they’ve changed over time.
- Tests: You may need tests like EMG (which checks muscle activity), nerve studies, blood tests, and sometimes MRI scans to rule out other conditions.
How Is ALS Treated?
There is no cure for ALS yet, but treatment can help manage symptoms and improve quality of life.
Doctors may suggest different types of therapy and support, such as:
- Physical therapy to keep muscles working as long as possible
- Speech therapy to help with speaking and swallowing
- Nutritional support to make sure you're getting the right food and fluids
- Breathing support if muscles that help you breathe become weak
Some treatments may slow down how fast symptoms get worse, but every person with ALS is different. That’s why care is usually personalized to your needs.
ALS should not be ignored. The earlier it’s diagnosed, the sooner you can get the right support and care.
When to See a Doctor Immediately
Some symptoms should never be ignored. Get medical help as soon as possible if you notice:
- Muscle weakness that gets worse quickly or spreads
- Trouble speaking, swallowing, or breathing
- Muscle twitching or cramps that don’t go away
- Loss of coordination or frequent falls without a clear cause
Don’t wait and hope it goes away. Early evaluation by a doctor can help you get the right tests, rule out other conditions, and start supportive care if needed.
Remember: Docus symptom checker can guide you to better understand what you're feeling, but only a healthcare professional can confirm if it's ALS.
