Is Chiari Malformation a Disability? How to Get Benefits
April 9, 2025
Fact Checked
The Social Security Administration (SSA) does not explicitly list Chiari malformation as a qualifying disability. However, it is still possible to receive Social Security Disability benefits if your symptoms are severe enough to keep you from working or carrying out daily activities.
The SSA will consider your medical condition as a qualifying disability if all the following are true:
You cannot perform substantial gainful activity (SGA) because of your condition.
You cannot do your previous work or adjust to other work because of your condition.
Your condition is expected to last at least 12 consecutive months or result in death.
What Is Chiari Malformation?
Chiari malformation is a neurological disorder that affects the cerebellum, the part of the brain responsible for balance and coordination.
Chiari malformation is a congenital or acquired condition in which the cerebellum protrudes through the foramen magnum, the opening at the base of the skull. This rare condition restricts the flow of cerebrospinal fluid that protects the brain and spinal cord, which can lead to serious complications.
There are four types of Chiari malformation, classified based on the presence of developmental abnormalities in the spine and brain, as well as how much brain tissue extends into the spinal canal.
Chiari Malformation Type 1: Also known as the adult form, this is the mildest and most common form, often diagnosed in adolescence or even adulthood.
Chiari Malformation Type 2: Sometimes referred to as Arnold-Chiari Malformation, and typically associated with spina bifida. This type is more severe and present at birth.
Chiari Malformation Type 3: A rare and life-threatening form where parts of the cerebellum and brainstem extend into the spinal cord.
Chiari Malformation Type 4: The most severe form involving an underdeveloped or missing cerebellum.
Common Chiari Malformation Symptoms
Chiari malformation affects everyone differently. Some people have little to no symptoms, while others struggle with severe, life-disrupting issues. It all comes down to how much pressure is put on the brain and spinal cord. Common symptoms include:
Chronic headaches, especially at the back of the head
Neck pain and stiffness
Dizziness and balance problems
Muscle weakness and coordination issues
Numbness or tingling in the hands and feet
Difficulty swallowing (dysphagia) and other speech problems
Tinnitus (ringing in the ears and hearing loss
Vision problems, including double vision and light sensitivity
Sleep apnea and breathing difficulties
Cognitive issues, such as memory loss and trouble concentrating
Can You Get Disability Benefits for Chiari Malformation?
Chiari malformation isn't explicitly listed in the SSA's Blue Book of qualifying disabilities, but that doesn't mean you can't get benefits. If your symptoms make it hard to work and go about your daily life, then you may still qualify for Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI).
Criteria for Getting Disability Benefits with Chiari Malformation
To qualify for disability benefits, applicants must prove that their medical condition meets the SSA's definition of disability. The SSA considers the following factors:
Severity of Symptoms
If Chiari malformation causes chronic pain, muscle weakness, or neurological impairments that limit mobility and cognitive functions, it may qualify for disability. The SSA assesses how symptoms impact the ability to concentrate and follow instructions, physical activities such as walking, standing, and sitting, and fine motor skills and hand-eye coordination.
Impact on Daily Activities
The SSA evaluates how the condition affects quality of life, including difficulty performing household tasks (like cooking and cleaning), limitations on personal care and hygiene, and the ability to drive or use public transportation.
Functional Limitations
A Residual Functional Capacity (RFC) assessment determines what individuals can still do in a work setting despite their impairments. For people with Chiari malformation, this might include limitations in lifting, carrying, walking, or standing up from a seated position.
Neurological symptoms like dizziness, numbness, headaches, or coordination issues can interfere with tasks requiring concentration or fine motor skills. If symptoms prevent the individual from sustaining full-time work or limit them to only sedentary, low-stress environments, the SSA may find them disabled.
Medical Evidence
Comprehensive medical documentation is crucial in proving disability. Evidence can include things like a doctor's diagnosis, MRI scans, treatment records, and a symptom journal.
Failed Medical Treatment Attempts
If surgical intervention, medications, and/or physical therapy fail to improve symptoms, this strengthens the claim. The SSA may require medical records documenting past and current treatments, as well as statements from medical professionals confirming the treatment resistance.
Non-medical Evidence
Additional supporting evidence, such as statements from friends and family, past employer reports, or a personal disability impact statement, can strengthen a disability claim.
