**What is‌ Amyotrophic Lateral Sclerosis (ALS)?**

**Q: What is ALS?**

**A:** Amyotrophic Lateral Sclerosis (ALS), ⁤also ⁤known as Lou Gehrig’s disease, is a progressive ⁢neurodegenerative disease that attacks motor ⁤neurons, the nerve cells ‌responsible for ⁣controlling voluntary muscle movement.

**Q: What are the Symptoms of⁣ ALS?**

**A:** Symptoms typically ⁢include:

– Muscle weakness and atrophy

– Difficulty speaking, swallowing, and⁤ breathing

– Twitching and cramping

– Progressive‌ paralysis

**Q: ‍What Causes ALS?**

**A:** The exact cause of ALS is⁣ unknown, but it is believed to‌ involve a ⁢complex⁤ interplay of genetic, environmental, and lifestyle factors. Approximately 10% of cases​ have a familial genetic basis.

**Q:‌ How is ALS Diagnosed?**

**A:** Diagnosis is based on a combination of:

– Neurological examination

– Electromyography (EMG) to measure electrical activity in muscles

– Imaging ‌studies like MRI ⁣to rule out other conditions

**Q: Is ALS Curable?**

**A:** Currently, ALS is incurable, ​but treatments can slow⁣ disease progression​ and improve⁢ quality of life.

**Q: What are⁣ the ⁣Treatment Options for ALS?**

**A:** Treatments focus ⁣on symptom ⁤management and include:

-⁢ Medication like riluzole and edaravone

– Physical and occupational therapy

– Speech ⁤and swallowing therapy

– Respiratory support

– Palliative care

**Q: What‍ is the Prognosis for ALS?**

**A:** The‍ average life expectancy after diagnosis is 2-5 years, but⁢ some people‍ live longer. Age of ⁢onset, disease type,​ and access to proper care can influence prognosis.

**Q: How is ALS Researched?**

**A:** Research into ALS aims to:

– Identify genetic and environmental risk factors

– Understand disease ⁤mechanisms

– Develop new therapies and treatments
