Symptoms of ALS or Lou Gehrig’s Disease

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s Disease, is a progressive neurodegenerative disorder that affects nerve cells in the brain and spinal cord. The disease is characterized by a variety of symptoms that worsen over time, leading to severe physical impairment.

Muscle Weakness and Atrophy

One of the earliest and most common symptoms of ALS is muscle weakness, which often begins in the limbs. Patients may notice difficulty in performing everyday tasks such as buttoning a shirt, turning a key, or walking. This muscle weakness is usually accompanied by muscle atrophy, where the muscles shrink and lose mass due to lack of use and nerve stimulation1.

Fasciculations and Cramps

Fasciculations, or muscle twitches, are another hallmark of ALS. These involuntary contractions can occur in any muscle group and are often visible under the skin. Muscle cramps are also frequent and can be quite painful, further contributing to the discomfort experienced by ALS patients1.

Spasticity and Hyperreflexia

As ALS progresses, patients may develop spasticity, which is characterized by stiff and tight muscles. This condition can make movement difficult and is often accompanied by hyperreflexia, an exaggerated reflex response. These symptoms are indicative of the upper motor neuron involvement in ALS1.

Dysarthria and Dysphagia

ALS can also affect the muscles responsible for speech and swallowing. Dysarthria, or slurred speech, is a common symptom that can make communication challenging. Dysphagia, or difficulty swallowing, can lead to choking and aspiration, posing significant risks for malnutrition and respiratory complications1.

Respiratory Complications

In the later stages of ALS, respiratory muscles become weakened, leading to breathing difficulties. This can result in shortness of breath, especially during physical activity or while lying down. Respiratory failure is a common cause of death in ALS patients, underscoring the critical need for respiratory support as the disease advances1.

Cognitive and Behavioral Changes

While ALS primarily affects motor neurons, some patients may experience cognitive and behavioral changes. These can include difficulties with executive functions, such as planning and decision-making, as well as changes in personality and behavior. These symptoms are less common but can significantly impact the quality of life for ALS patients and their families1.

Conclusion

ALS is a multifaceted disease with a wide range of symptoms that progressively worsen over time. From muscle weakness and atrophy to respiratory complications and cognitive changes, the impact of ALS on patients is profound. Understanding these symptoms is crucial for early diagnosis and management, although effective treatments remain limited.
