Amyotrophic Lateral Sclerosis (ALS): Exploring the Disease and Its Impact

What is ALS?

Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND) or Lou Gehrig's disease in the United States, is a progressive neurological disorder that affects the motor neurons in the brain and spinal cord.

Limb Onset ALS

Around 70% of people with ALS experience limb onset ALS. In this form of ALS, symptoms initially manifest in the arms or legs, leading to weakness and muscle atrophy in the affected limbs.

Causes and Symptoms

The exact cause of ALS is unknown, but it is believed to be a combination of genetic and environmental factors. Symptoms of ALS typically include muscle weakness, difficulty swallowing and speaking, and respiratory problems.

Diagnosis and Treatment

ALS is diagnosed based on a physical examination, medical history, and electromyography (EMG) or nerve conduction studies. There is no cure for ALS, but treatments can help manage symptoms and improve quality of life.

Impact and Prognosis

ALS is a devastating disease that affects not only the individual but also their family and loved ones. The average life expectancy after diagnosis is three to five years, but some people may live longer with appropriate care and support.
