Understanding ALS: Navigating the Journey Together

Amyotrophic Lateral Sclerosis (ALS) is a complex neurodegenerative disease that affects the nerve cells responsible for controlling voluntary muscle movement. While there is currently no cure, ALS United Rocky Mountain is dedicated to providing comprehensive support, resources, and hope to individuals and families affected by ALS. By working together, we can improve the lives of those living with ALS and drive research towards effective treatments and a cure.

Key Takeaways:

ALS is caused by a complex interplay of genetic and environmental factors, with 90-95% of cases occurring sporadically and 5-10% being inherited.
Early symptoms of ALS can be subtle, leading to delays in diagnosis. A definitive diagnosis requires ruling out other conditions through clinical examinations, imaging studies, and laboratory tests.
While average life expectancy is 2-5 years after diagnosis, some people with ALS live 10 years or more. Multidisciplinary care at specialized ALS clinics can improve quality of life and survival.
FDA-approved medications, therapies, and supportive care from a multidisciplinary team can help manage symptoms and maintain independence. Participating in clinical trials offers access to promising experimental treatments.
Connecting with support groups and organizations like ALS United Rocky Mountain provides vital emotional support, practical resources, and opportunities to get involved in advocacy and research efforts.

Definition and Overview of ALS

Causes and Risk Factors

While the exact cause of ALS remains unknown, research suggests that a complex interplay of genetic and environmental factors likely contribute to the development of the disease. About 5-10% of ALS cases are considered familial or inherited, caused by changes in specific genes¹. However, the vast majority of ALS cases, around 90-95%, occur sporadically with no clear genetic link or family history of the disease¹.

Certain demographic factors are associated with an increased risk of developing ALS. The disease is most commonly diagnosed between the ages of 55 and 75, with men being slightly more likely than women to develop ALS, especially before age 65¹. Additionally, some studies have found that military veterans have a higher risk of ALS compared to the general population, possibly due to exposures during service¹.

Types of ALS: Sporadic and Familial

Sporadic ALS accounts for 90-95% of all cases and seems to occur randomly with no clearly associated risk factors or family history. Familial ALS, responsible for 5-10% of cases, is caused by inherited genetic mutations passed down from one generation to the next¹. While having a genetic mutation associated with ALS increases a person’s risk, it does not necessarily mean they will develop the disease, as other genetic and environmental factors likely influence onset¹.

Symptoms and Progression

Early Symptoms and Signs

Early symptoms of ALS can be subtle and may include muscle weakness, tightness, cramping, or twitching. Fine motor skills may become impaired, leading to difficulties with tasks like writing or buttoning clothes. Slurred speech and trouble swallowing can also be early indicators⁴.

Stages of ALS Progression

ALS progresses through several stages, although the exact course can vary from person to person. As the disease advances, muscle weakness and paralysis become more widespread, affecting mobility, breathing, speaking, and swallowing³. In late stages, patients become dependent on caregivers and require interventions like feeding tubes and ventilation support to maintain quality of life³.

“By the late stages, most voluntary muscles are paralyzed and breathing is severely compromised. Mobility is extremely limited and patients become dependent on caregivers for all activities of daily living.”³

Factors Affecting Disease Progression

Several factors can influence the rate of decline and life expectancy in ALS. Bulbar onset ALS, which first affects the muscles of the face, mouth, and throat, tends to progress more rapidly than spinal onset ALS⁴. Age, overall health, and genetics also play a role, with younger and healthier patients often experiencing slower progression¹. Proactive use of breathing and feeding support, medications, and multidisciplinary care can help maintain function and quality of life longer³.

Diagnosis and Prognosis

Diagnostic Process and Tests

Diagnosing ALS involves a combination of clinical examinations, imaging studies, and laboratory tests to rule out other conditions and support an ALS diagnosis. Electrodiagnostic studies can detect signs of motor neuron degeneration, while imaging tests like MRI help exclude conditions that might mimic ALS¹. Blood tests, genetic testing, and muscle biopsies may also be used to exclude other disorders¹.

Challenges in Diagnosing ALS

Diagnosing ALS can be complex and lengthy, as there is no single definitive test for the disease. Early symptoms can be subtle and overlap with other neurological disorders, often leading to delays in diagnosis¹. On average, it takes about 11 months from symptom onset to a formal ALS diagnosis⁵. The heterogeneity of ALS presentations and lack of a clear biological marker further complicate the diagnostic process¹.

Life Expectancy and Survival Rates

While ALS is progressive and ultimately fatal, life expectancy can vary significantly. On average, people with ALS survive 2-5 years after diagnosis, but about 20% live 5 years or more, and up to 10% survive for more than 10 years¹. Factors influencing life expectancy include type of ALS, age, genetics, and timing of diagnosis and treatment¹. Multidisciplinary care at specialized ALS clinics has been shown to extend survival and improve quality of life⁹. It is highly encouraged to find an ALS clinic nearest you for every ALS patient. ALS United Rocky Mountain is engaged with all 5 ALS clinics that exist in CO, WY and UT.

Treatment and Management

FDA-Approved Medications

While there is no cure for ALS, the FDA has approved two medications, riluzole and edaravone, that can modestly slow disease progression. Riluzole works by decreasing damage to motor neurons, while edaravone may slow decline in daily functioning¹. Starting these medications early in the disease course may help preserve function and independence longer.

Therapies and Supportive Care

Comprehensive care from a multidisciplinary team of specialists is essential for managing the complex needs of ALS. This includes regular evaluations and interventions from neurologists, physical and occupational therapists, speech therapists, respiratory therapists, nutritionists, social workers, and mental health professionals⁹. Therapies focus on maintaining strength, mobility, and function through exercise, stretching, and adaptive equipment. Breathing and feeding support, such as noninvasive ventilation and feeding tubes, become critical as the disease progresses¹.

At ALS United Rocky Mountain, we believe multidisciplinary care is the gold standard for helping people with ALS maintain the best possible quality of life. Our dedicated research and support services are designed to provide comprehensive, coordinated care to the ALS community.

Clinical Trials and Future Treatments

Researchers are working hard to develop new treatments that may slow ALS progression and improve quality of life. Promising therapies being investigated include drugs targeting underlying disease mechanisms, stem cell therapies to regenerate motor neurons, and gene therapies for inherited ALS¹. Participating in clinical trials offers people with ALS the opportunity to access experimental treatments and help drive research forward.

Coping and Support

Emotional and Psychological Impact

An ALS diagnosis can be overwhelming and lead to a range of emotions including grief, anger, fear, and depression. It’s important for patients and caregivers to acknowledge and express these feelings, and seek support from loved ones, mental health professionals, or support groups¹. Counseling and medications can help manage the emotional challenges of living with ALS.

Lifestyle Adjustments and Adaptations

As ALS progresses, patients must make significant lifestyle adjustments to maintain independence and quality of life. This includes using adaptive equipment and making home modifications for accessibility. Physical and occupational therapists assist with exercises and techniques to preserve function, while speech therapists help with communication strategies¹. Breathing and feeding support, such as noninvasive ventilation and feeding tubes, become essential in later stages³.

Support Groups and Resources for Patients and Caregivers

Connecting with others facing similar challenges through support groups can provide validation, information, and a sense of community for people with ALS and their caregivers. Here at ALS United Rocky Mountain, we offer virtual support groups, as well as educational resources for both patients and caregivers. Caregivers should prioritize their own self-care and seek respite services when needed. These groups are always highly attended and always free of charge.
