ALS: What is it and How Does it Affect the Body?

Definition of Amyotrophic Lateral Sclerosis (ALS)

Amyotrophic lateral sclerosis (ALS) is a type of motor neuron disease that affects the brain and spinal cord. Motor neurons are cells that send signals from the brain to the muscles, allowing us to move and speak.

Bulbar and Pseudobulbar Palsy in ALS

Bulbar and pseudobulbar palsy are two conditions that can occur in ALS. Bulbar palsy affects the muscles that control swallowing, speech, and facial movements. Pseudobulbar palsy affects the muscles that control facial expressions and emotions.

Early Signs and Symptoms of ALS

The early signs and symptoms of ALS can vary, but some of the most common include:

• Difficulty walking or doing your normal daily activities
• Breathlessness or shortness of breath that occurs while lying down
• Recurrent muscle weakness
