Amyotrophic lateral sclerosis (ALS) is characterized by which of the following symptoms?

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a progressive neurodegenerative disorder that affects motor neurons in the brain and spinal cord. The primary symptoms associated with ALS include weakness, muscle atrophy, and respiratory difficulties, often referred to as dyspnea.

Weakness occurs because the degeneration of motor neurons leads to a decrease in muscle strength and control. Muscle atrophy is a direct result of the loss of motor neuron input to the muscles, causing them to shrink and weaken over time. Dyspnea arises due to weakness in the muscles that are responsible for respiration, making it difficult for individuals with ALS to breathe as the disease progresses.

Understanding these symptoms is crucial for occupational therapy assistants, as they can influence the types of interventions and support strategies needed for individuals living with this condition. Addressing muscle weakness and providing adaptive strategies can enhance the quality of life for those impacted by ALS.
