Synopsis: This article provides a clear overview of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, describing it as a rapidly progressive, fatal neurological disorder that attacks the nerve cells controlling voluntary muscles. It explains that ALS leads to muscle weakness, atrophy, and ultimately paralysis, with most patients facing respiratory failure within three to five years of symptom onset. The article details early symptoms such as muscle twitching, weakness, slurred speech, and difficulty swallowing, while noting that ALS typically does not impair senses or, in most cases, cognitive function - though some individuals may experience memory or decision-making difficulties. The cause of ALS remains unknown, and diagnosis is based on clinical evaluation and tests to rule out other conditions. The article highlights that riluzole is the primary FDA-approved medication, offering modest survival benefits, and emphasizes the importance of multidisciplinary care to manage symptoms and improve quality of life. This information is authoritative due to its thorough coverage of symptoms, diagnosis, treatment, and prognosis, and it is especially useful for individuals living with disabilities, caregivers, and seniors seeking reliable facts about ALS - Disabled World (DW).

Introduction

Amyotrophic lateral sclerosis (ALS), sometimes called Lou Gehrig's disease, is a rapidly progressive, invariably fatal neurological disease that attacks the nerve cells (neurons) responsible for controlling voluntary muscles. Alternate Names include Aran-Duchenne, Gehrig's Disease, Lou Gehrig's Disease, Motor Neuron Disease.

The U.S. Social Security Administration (SSA) has included Amyotrophic Lateral Sclerosis (ALS) as a Compassionate Allowance to expedite a disability claim.

Main Content

In ALS, the upper and lower motor neurons degenerate or die, ceasing to send messages to muscles. Unable to function, the muscles gradually weaken, waste away, and twitch. Eventually, the ability of the brain to start and control voluntary movement is lost.

Individuals with ALS lose their strength and the ability to move their arms, legs, and body. When muscles in the diaphragm and chest wall fail, individuals lose the ability to breathe without ventilatory support. The disease does not affect a person's ability to see, smell, taste, hear, or recognize touch and does not usually impair their thinking or other cognitive abilities. However, several recent studies suggest that a small percentage of patients may experience problems with memory or decision-making, and there is growing evidence that some may even develop a form of dementia.

Early Symptoms:

Males are affected more often than women, and the onset of ALS may be so subtle that the symptoms are frequently overlooked. The earliest symptoms of Lou Gehrig's Disease may include:

Cause(s)

The cause of ALS is not known, and scientists do not yet know why ALS strikes some people and not others. There is no one test or procedure to establish the diagnosis of ALS.

The diagnosis of ALS is based on history, neurological findings consistent with the diagnosis of ALS, and electro-physiological and neuroimaging testing to rule out other impairments that may cause similar signs and symptoms. The diagnosis may be supported by electrophysiological studies (Electromyogram [EMG] and nerve conduction study [NCS], but these tests may be negative or only suggestive of the diagnosis.

Treatment(s)

No cure has yet been found for ALS. However, the FDA has approved the first drug treatment for the disease-riluzole (Rilutek).

Clinical trials with ALS patients showed that riluzole prolongs survival by several months. Riluzole does not reverse the damage already done to motor neurons, and patients taking the drug must be monitored for liver damage and other possible side effects. However, this first disease-specific therapy offers hope that the progression of ALS may one day be slowed by new medications or combinations of drugs.

Other treatments for ALS are designed to relieve symptoms and improve the quality of life for patients.

Regardless of the part of the body first affected by the disease, muscle weakness, and atrophy spread to other parts of the body as the disease progresses. Most individuals with ALS die from respiratory failure, usually within 3 to 5 years from the onset of symptoms.

Insights, Analysis, and Developments

Editorial Note: While no cure exists, this thorough summary emphasizes the importance of accurate, early diagnosis and coordinated care to preserve function and dignity. It reminds readers that ongoing research and evolving therapies continue to offer hope, making timely medical engagement and informed advocacy essential for anyone impacted by ALS. The article underscores the harsh reality of ALS as a relentless disease with no cure, yet it also highlights the resilience of those affected and the scientific community's persistent efforts to find effective treatments. While the current landscape offers limited options like riluzole, the emphasis on clinical trials and emerging therapies signals a future where ALS might be slowed or even halted. For patients and families, this balance of sobering facts and cautious optimism serves as a call to engage with multidisciplinary care teams and advocacy groups, ensuring that every step forward in research translates to better quality of life for those living with this devastating condition - Disabled World (DW).
