Myasthenia Gravis and SSDI Eligibility

Myasthenia gravis is a chronic autoimmune disorder that disrupts communication between your nerves and muscles. This breakdown leads to fluctuating weakness in your voluntary muscles, which can worsen with activity and improve with rest. It often affects the muscles that control your eye movement, facial expression, chewing, swallowing, and breathing.

For you, daily life can become unpredictable. Simple tasks like holding up your head, speaking clearly, or walking short distances may become exhausting. In severe cases, the weakness can impact the muscles responsible for your breathing, creating a dangerous situation that requires immediate medical intervention.

Under Listing 11.12, the Social Security Administration evaluates the severity of your muscle weakness despite you following your doctor's prescribed treatment for at least three months. They look for evidence of extreme motor dysfunction in two extremities, or significant bulbar and neuromuscular issues that affect your ability to breathe, swallow, or speak.

SSA also considers if your condition causes marked limitations in physical functioning combined with mental health challenges. To qualify, your medical records must show that these limitations persist or are expected to last for at least 12 months. They focus on how these symptoms interfere with your ability to initiate, sustain, and complete work-related tasks. An attorney can help you gather the evidence needed to meet these criteria.

Strong claims rely on detailed medical records that document your diagnosis and your response to treatment. This includes clinical examination notes, results from nerve conduction studies, and documentation of any myasthenic crises requiring mechanical ventilation. If you require a feeding tube or other nutritional support, these records are critical for your application.

Non-medical evidence is equally important to show how the disease impacts your daily life. Statements from your treating physician regarding your physical limitations, along with reports from family members about your fatigue and inability to perform routine activities, help paint a clear picture. An attorney can help you organize this evidence to build a persuasive case.

Many claims are denied because your medical evidence fails to show that symptoms persist despite consistent adherence to prescribed treatment. SSA often denies cases where the documentation does not clearly link your muscle weakness to an inability to perform basic work functions. If your records do not capture the frequency and intensity of your periods of exacerbation, the agency may conclude your condition is not severe enough to prevent all work. An attorney can help you address these gaps in your evidence.

A disability attorney helps by ensuring your medical records are complete and directly address the specific criteria in Listing 11.12. They can work with your medical providers to obtain detailed statements that explain how your muscle weakness limits your physical and mental functioning on a daily basis. By organizing your evidence and preparing you for the hearing process, an attorney helps you present the strongest possible case to the Social Security Administration.
