Topic Definition

Invisible Disability

An invisible disability is a physical, mental, or neurological condition that cannot be seen from the outside yet still limits or challenges a person's movement, senses, or daily activities. Because there is no wheelchair, white cane, or hearing aid to signal it, others often fail to recognize the difficulty, and people living with conditions such as chronic pain, chronic fatigue, or a sleep disorder are sometimes wrongly accused of faking or exaggerating. These hidden conditions can stem from chronic illness, injury, birth disorders, or mental health challenges, and they cover a broad spectrum that includes everything from diabetes and epilepsy to depression, migraines, and Fibromyalgia. Under the Americans with Disabilities Act of 1990, a person qualifies as having a disability if an impairment substantially limits one or more major life activities, whether or not that impairment is visible to anyone else.

About This Section

What are Invisible Disabilities?

Invisible Disability, or hidden disability, is an umbrella term that captures a whole spectrum of hidden disabilities or challenges, primarily neurological. Invisible disabilities, or hidden disabilities, are defined as disabilities that are not immediately apparent. Some people with visual or auditory disabilities who do not wear glasses or hearing aids, or discreet hearing aids, may not be obviously disabled. Some people who have vision loss may wear contacts.

A sitting disability is another category of invisible impairments; chronic back pain usually causes sitting problems. Those with joint issues or chronic pain may not use mobility aids on some days. Although the disability creates a challenge for the person who has it, the reality of the disability can be difficult for others to recognize or acknowledge. Others may not understand the cause of the difficulty if they cannot see evidence of it.

People with invisible disabilities, such as chronic pain or some sleep disorder, are often accused of faking or imagining their disabilities. These symptoms can occur due to chronic illness, chronic pain, injury, birth disorders, etc., and are not always obvious to the onlooker.

Invisible Disabilities are certain kinds of disabilities that are not immediately apparent to others. It is estimated that 10% of people in the U.S. have a medical condition that could be considered a type of invisible disability.

Nearly one in two people in the U.S. has a chronic medical condition of one kind or another. Still, most people are not considered disabled, as their medical conditions do not impair their normal activities. These people do not use an assistive device, and most look and act perfectly healthy.

According to the Americans with Disabilities Act of 1990 (ADA), an individual with a disability is a person who: Has a physical or mental impairment that substantially limits one or more major life activities; has a record of such an impairment; or is regarded as having such an impairment.

Generally, seeing a person in a wheelchair, wearing a hearing aid, or carrying a white cane tells us a person may be disabled. But what about invisible disabilities that make daily living a bit more difficult for many people worldwide?

Invisible disabilities can include chronic illnesses such as renal failure, diabetes, and sleep disorders if those diseases significantly impair normal activities of daily living.

For example, people with visual or auditory impairments do not wear hearing aids or eyeglasses, so they may not seem impaired. Those with joint conditions or problems who suffer chronic pain may not use any mobility aids on good days.

Another example is Fibromyalgia, which is now understood to be the most common cause of chronic musculoskeletal pain. Sources estimate between 3 and 26 million Americans suffer from this hidden condition.

Other Types of Invisible Disabilities

• Chronic Pain: A variety of conditions may cause chronic pain. A few of those reasons may be back issues, bone disease, physical injuries, etc. Chronic pain may not be noticeable to people who do not understand the victim's medical condition.
• Chronic Fatigue: This type of disability refers to an individual who constantly feels tired. This can be extremely debilitating and affect every aspect of a person's everyday life.
• Mental Illness: There are many mental illnesses that do qualify for disability benefits. Some examples are depression, attention deficit disorder, schizophrenia, agoraphobia, and many others. These diseases can also be completely debilitating to the victim and can make performing everyday tasks challenging, if not impossible.
• Chronic Dizziness: Often associated with problems of the inner ear, chronic dizziness can lead to impairment when walking, driving, working, sleeping, and other common tasks.

People with psychiatric disabilities comprise a large segment of the invisibly disabled population covered under the Americans with Disabilities Act of 1990. Invisible disabilities can also include chronic illnesses such as renal failure, diabetes, and sleep disorders if those diseases significantly impair normal activities of daily living.

96% of people with chronic medical conditions live with an invisible illness. Many people living with a hidden physical disability or mental challenge can still be active in their hobbies, work, and be active in sports. On the other hand, some struggle to get through their day at work, and some cannot work at all.

List of SOME Invisible Disabilities

U.S. Invisible Disability Statistics

About 10% of Americans have a medical condition that could be considered an invisible disability. 96% of people with chronic medical conditions live with an invisible condition. These people do not use a cane or any assistive device and act like they don't have a medical condition. About 25% have some activity limitation, ranging from mild to severe; the remaining 75% are not disabled by their chronic conditions. Although the disability creates a challenge for the person who has it, the reality of the disability can be difficult for others to recognize or acknowledge. Others may not understand the cause of the problem if they cannot see evidence of it.

Invisible Disability in Society

Invisible disabilities are college students' most common type of disability. For example, students with learning disabilities, Attention Deficit Hyperactivity Disorder, or psychiatric disabilities may request accommodations even though they do not appear to have a disability. There are numerous other hidden or invisible disabilities, such as heart conditions, Chronic Fatigue Syndrome, Fibromyalgia, and Seizure Disorder.

Hundreds of conditions, illnesses, and injuries can result in a hidden disability - anemia, brain injuries and strokes, allergies, epilepsy, heart diseases, lung conditions, mental illnesses, and chronic pain are just a few examples. Yet, although we are all aware of these individual conditions, there is much to be learned about the shared needs and experiences of the hidden disability community as the unique group it is. In Canada, a movement by Laura Brydges, co-founder of the Hidden Disability Symbol Canada movement, along with the Brain Injury Society of Toronto (BIST) and Brain Injury Canada (BIC), is currently in progress.

Also a recent scheme known as the Sunflower Lanyard Program has been launched in the U.K. The Hidden Disabilities Sunflower aims to help others identify when support may be needed for those with disabilities such as autism, dementia, anxiety, or other conditions that may not be immediately obvious to others.

Many organizations, governments, and institutions implement policies and regulations to accommodate persons with invisible disabilities. Governments and school boards have implemented screening tests to identify students with learning disabilities and other invisible disabilities, such as vision or hearing difficulties or problems in cognitive ability, motor skills, or social or emotional development. If a hidden disability is identified, resources can be used to place a child in a special education program that will help them progress in school.

Frequently Asked Questions

What is the Hidden Disabilities Sunflower symbol?

It is a discreet green lanyard with a sunflower design that signals to staff and others that the wearer may have a hidden condition and could need extra help, patience, or time.

Can students get accommodations for invisible disabilities?

Yes. Students with conditions such as learning disabilities, ADHD, or psychiatric disabilities can request accommodations, and many schools use screening to identify hidden needs.

Are invisible disabilities protected by law?

In the United States, the Americans with Disabilities Act protects people whose impairments substantially limit major life activities, whether or not the condition is visible.

Why are invisible disabilities often misunderstood?

Because there is no outward sign, others may doubt the condition exists, which can lead to disbelief, stigma, and accusations of faking despite genuine daily challenges.

Is chronic fatigue considered an invisible disability?

Yes. Chronic fatigue can be deeply debilitating and affect nearly every part of daily life, yet it produces no visible signs, so it is classed as a hidden disability.

Do people with invisible disabilities always look healthy?

Often they do, and many stay active in work, hobbies, and sports, while others struggle through the day or cannot work at all, since severity varies widely from person to person.

What is a sitting disability?

A sitting disability is a hidden impairment, usually caused by chronic back pain or joint problems, that makes remaining seated difficult even though it is not obvious to onlookers.
