Motor neuron diseases (MNDs) are a group of progressive neurological disorders that destroy motor neurons—the nerve cells that control voluntary muscles, such as those used to speak, walk, breathe, and swallow. This group of disorders includes diseases such as amyotrophic lateral sclerosis (ALS), also called Lou Gehrig’s disease. Other types include progressive bulbar palsy, primary lateral sclerosis (PLS), progressive muscular atrophy (PMA), spinal muscular atrophy (SMA), Kennedy’s disease, and post-polio syndrome.
Understanding Motor Neuron Diseases
MNDs can be sporadic or inherited. Symptoms typically develop gradually and may begin with muscle weakness or stiffness. As the disease progresses, there is increasing disability due to muscle wasting, paralysis, and loss of mobility. Patients may also experience difficulty speaking (dysarthria), swallowing (dysphagia), and breathing (dyspnea). Although mental function is often preserved, some people develop cognitive impairment.
There is currently no cure for MND. Treatment focuses on managing symptoms, slowing progression, and improving quality of life. This may include physical therapy, respiratory support, speech therapy, and assistive devices.
Functional Limitations That Affect Work
Motor neuron diseases can have a profound effect on a person’s ability to work. The progressive nature of these diseases means that even people who begin with mild symptoms may become unable to maintain employment as their condition worsens.
- Physical Jobs: Construction workers, landscapers, nurses, or anyone who must lift, walk, or stand for long periods of time may become unable to meet the physical demands of their jobs.
- Sedentary Jobs: Office workers may have difficulty typing, using a mouse, speaking clearly on the phone, or sitting for long periods due to muscle weakness or spasms.
The fatigue and physical limitations caused by MNDs often make it impossible to maintain a consistent work schedule or to perform even light work reliably.
Medical Evidence to Support an LTD Claim
To qualify for long-term disability benefits, claimants must provide extensive medical documentation. Key pieces of evidence include:
- Neurological evaluations
- Electromyography (EMG) and nerve conduction studies (NCS) to demonstrate motor neuron dysfunction
- MRI scans to rule out other conditions
- Clinical notes from treating neurologists
- Pulmonary function tests if respiratory muscles are involved
- Physical and occupational therapy reports documenting functional limitations
Consistent treatment and follow-up records can strengthen a claim by showing disease progression and its impact on daily activities.
Common Challenges in MND LTD Claims
Even with a clear diagnosis like ALS, claimants may encounter obstacles such as:
- Delays in diagnosis, which can complicate claim timelines.
- Inadequate functional documentation, especially when symptoms are initially mild.
- Surveillance by insurers to disprove the extent of limitations.
- Independent medical examinations (IMEs) that downplay the severity or progression or your disease.
Many claimants assume that a diagnosis like ALS will make their long-term disability claim easy. Unfortunately, insurance companies often look for any excuse to delay or deny benefits. Whether it’s through surveillance, biased medical reviews, or claims of insufficient documentation, they can challenge even the most well-supported cases.
Hypothetical Case Example
John, a 49-year-old warehouse manager, began experiencing frequent muscle spasms and weakness in his right arm. Over time, he developed difficulty walking and speaking. After undergoing EMG and NCS testing, he was diagnosed with ALS. Despite his worsening condition, his claim for long-term disability was denied. The insurance company relied on an independent medical examination (IME) that minimized his symptoms and concluded that he could still perform light-duty work.
Careful attention to medical details and strong supporting evidence are critical to overcoming these challenges.
