What is an invisible disability?

An invisible disability is a physical, mental, or neurological condition that is not immediately apparent to others. The person may appear healthy or fully able-bodied while managing significant challenges related to pain, fatigue, cognitive function, mobility, sensory processing, or other symptoms depending on their condition.

The word "invisible" refers to the visibility of the disability to outside observers, not to the significance of its impact. Many people with invisible disabilities face considerable daily challenges that their colleagues, classmates, and even family members know nothing about.

This list covers only a portion of the conditions that qualify. The Invisible Disabilities Association defines an invisible disability as a physical, mental, or neurological condition that limits a person's movements, senses, or activities and is largely invisible to the casual observer.

How common are invisible disabilities in Canada?

1 in 5
Canadians has a disability. Between 70 and 80% of those disabilities are non-apparent.

That means in a team of 20 people, roughly four have a disability. Of those four, three are probably managing it invisibly. The person who is always late might be managing chronic fatigue. The colleague who takes a long time to respond to emails might be managing pain levels. The employee who works from home most days might have a condition that makes commuting difficult.

Most people with invisible disabilities have never told their workplace about them. The most common reasons: fear of being treated differently, concern about career impact, not wanting to be seen as less capable, and simply not knowing how the conversation would go.

The cost of hiding an invisible disability

Lauren Pires was born with Central Core Disease, a rare neuromuscular disorder that gives her approximately 33% of the average person's physical strength. For over 30 years, she hid it completely. She never told employers, colleagues, or most people in her life.

What she discovered was that hiding the disability took more energy than the disability itself. Managing other people's perceptions, compensating for limitations without explanation, and performing normalcy every day adds a significant invisible load on top of the condition itself. Many people with invisible disabilities describe this as masking.

When Lauren eventually began speaking about her condition publicly in 2022, she heard from hundreds of people who described the same experience. The hiding was often harder than the condition.

Invisible disabilities in the workplace

Workplaces are where the impact of invisible disability invisibility is most acute. Employees with invisible disabilities often face specific challenges that most HR policies and inclusion programs haven't fully addressed:

  • Disclosure decisions — whether to tell a manager or HR, and what the consequences might be
  • Accommodation requests without a visible or "recognized" condition
  • Judgement for behaviors that are actually symptoms: being late, leaving early, taking frequent breaks, working from home, turning cameras off
  • The energy cost of masking throughout a full working day
  • Lack of language among managers and colleagues for these conversations

Disability inclusion programs that focus only on visible or mobility-related disability miss the majority of disabled employees. Building a truly inclusive workplace means understanding and addressing invisible disability too.

Invisible Disabilities Week

Invisible Disabilities Week takes place in October each year. It was established by the Invisible Disabilities Association to raise awareness and build understanding of the hidden challenges faced by people with non-apparent conditions.

Organizations across Canada and the US use the week for internal education sessions, ERG events, and awareness campaigns. Lauren Pires has delivered invisible disability keynotes for several organizations during this period.

Rare Disease Day and invisible disabilities

Many rare diseases are also invisible disabilities. Rare Disease Day is observed on February 28 each year (or February 29 in leap years). Lauren Pires led the #LightUpForRare campaign in Canada, coordinating the lighting of 26 landmarks across 18 cities for Rare Disease Day 2026 in partnership with the Canadian Organization for Rare Disorders.

FAQ

Is depression an invisible disability?

Yes. Depression and other mental health conditions are recognized as invisible disabilities when they substantially limit a person's life activities. The Invisible Disabilities Association includes mental health conditions within its definition of invisible disability.

What is the difference between an invisible disability and a chronic illness?

The terms overlap significantly. A chronic illness is a health condition that persists over time, typically longer than three months. An invisible disability is defined by its non-apparent nature. Many chronic illnesses are also invisible disabilities, because the person lives with the condition continuously and it is not visible to others. Not all chronic illnesses limit function to the degree that qualifies as a disability, but many do.

Do I have to disclose an invisible disability at work?

In Canada, employees are not legally required to disclose a disability to their employer unless they are requesting accommodation. If accommodation is requested, the employee may need to provide documentation from a healthcare provider, though they are generally not required to disclose their specific diagnosis.

What does "non-apparent disability" mean?

Non-apparent disability is another term for invisible disability. It describes a disability that is not visible to outside observers. The terms invisible disability, non-apparent disability, and hidden disability are often used interchangeably.
