ALS: A Devastating Neurodegenerative Disease

Overview

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a debilitating neurodegenerative condition that affects motor neurons in the brain and spinal cord. These neurons are responsible for controlling voluntary muscle movement, and their progressive degeneration leads to muscle weakness, atrophy, and eventual paralysis.

Symptoms and Progression

ALS symptoms typically appear gradually and worsen over time. Common early signs include muscle weakness, fatigue, and difficulty walking or speaking. As the disease progresses, the weakness spreads to other muscles, affecting mobility, breathing, and swallowing. Over time, patients may become completely paralyzed and dependent on ventilators and feeding tubes.

Causes and Risk Factors

The exact cause of ALS is unknown, but a combination of genetic and environmental factors is believed to play a role. Most cases are sporadic, occurring without any known family history, while about 10% of cases are inherited. Risk factors include age (most cases occur after the age of 50), family history, and certain occupational exposures.

Diagnosis and Treatment

Diagnosing ALS can be challenging due to the gradual onset and similar symptoms to other conditions. A thorough physical examination, neurological tests, and electromyography (EMG) are used to assess muscle function and diagnose ALS. Unfortunately, there is no cure for ALS, but treatments can help manage symptoms and improve quality of life. These treatments include physical therapy, respiratory support, assistive devices, and medications to relieve muscle spasms and stiffness.
