Understanding Disability

Understanding different disabilities breaks down stereotypes and misconceptions that create barriers. When people understand how disabilities actually affect individuals—and what accommodations can help—they can make more inclusive spaces in their communities.


Overview

Disability is any condition of the body or mind that makes it more difficult for a person to do certain activities and interact with the world around them. There are many types of disabilities affecting vision, movement, thinking, remembering, learning, communicating, hearing, mental health, and more.

Important Note on Language: Some people prefer "person with a disability" (person-first language), while others prefer "disabled person" (identity-first language). Both are respectful—what matters most is using the language an individual prefers. We use both forms throughout this site.

Types of Disabilities

Learning Disabilities

What They Are: Learning disabilities affect how the brain processes information, making it difficult to acquire certain academic skills despite average or above-average intelligence.

Types Include:

  • Dyslexia: Difficulty with reading, spelling, and writing

  • Dysgraphia: Difficulty with writing and fine motor skills

  • Dyscalculia: Difficulty with math concepts and calculations

  • Specific Learning Disabilities (SLD): Challenges in specific academic areas

Understanding the Impact:

  • 2.4 million school-age students in the U.S. have SLDs

  • More than 90% of students with SLDs are not proficient in reading or math by 4th and 8th grade

  • Black and Hispanic students with SLDs face even greater opportunity gaps

  • Only 17% receive accommodations in college vs. 94% in K-12

Common Accommodations: Extended time on tests, alternative formats for materials, note-taking assistance, assistive technology, preferential seating

Attention-Deficit/Hyperactivity Disorder (ADHD)

What It Is: A neurodevelopmental condition affecting attention, impulse control, and activity levels.

Characteristics:

  • Difficulty sustaining attention

  • Impulsivity

  • Hyperactivity (in some but not all cases)

  • Executive function challenges (organization, time management, planning)

Understanding the Impact: ADHD affects learning, work, and social relationships. It's not about trying harder—it's about how the brain is wired.

Common Supports: Structured routines, breaking tasks into smaller steps, movement breaks, fidget tools, medication (when appropriate), coaching

Autism Spectrum Disorder (ASD)

What It Is: A developmental disability affecting communication, behavior, and social interaction. Autism exists on a spectrum, meaning it affects people differently and to varying degrees.

Characteristics:

  • Differences in social communication

  • Repetitive behaviors or restricted interests

  • Sensory sensitivities (to light, sound, touch, etc.)

  • Unique strengths (often in pattern recognition, attention to detail, memory)

Important Note: Many autistic individuals prefer identity-first language ("autistic person") and view autism as a fundamental part of their identity, not something to be "cured."

Common Supports: Clear communication, predictable routines, sensory accommodations, visual supports, accepting and valuing neurodiversity

Physical Disabilities

What They Are: Conditions affecting a person's mobility, dexterity, or physical capacity.

Types Include:

  • Mobility impairments (requiring wheelchairs, walkers, canes)

  • Limb differences or amputations

  • Cerebral palsy

  • Muscular dystrophy

  • Spinal cord injuries

  • Arthritis

Understanding the Impact: Physical disabilities don't affect intelligence or capability—they affect how someone moves or interacts physically with their environment.

Common Accommodations: Wheelchair ramps and accessibility, adjustable furniture, accessible bathrooms, adaptive equipment, extra time for transitions

Vision Impairment

What It Is: A decreased ability to see that cannot be corrected with glasses or contact lenses. Ranges from low vision to blindness.

Types Include:

  • Low vision

  • Color blindness

  • Blindness (total or legal)

  • Cortical visual impairment

Common Supports: Screen readers, braille materials, high-contrast materials, magnification devices, audio descriptions, guide dogs or white canes

Deaf and Hard of Hearing

What It Is: Hearing loss ranging from mild to profound. The Deaf community (capital D) shares a distinct culture and language (American Sign Language).

Important Note: Many Deaf individuals don't view deafness as a disability but as a cultural identity. Always respect individual preferences.

Common Accommodations: Sign language interpreters, captions, assistive listening devices, visual alerts, communication access in real-time

Intellectual Disability

What It Is: Characterized by significant limitations in intellectual functioning and adaptive behavior, which covers everyday social and practical skills.

Understanding the Impact: People with intellectual disabilities can learn and develop with appropriate supports. They have unique strengths and the right to make their own choices.

Common Supports: Simplified language, visual supports, extra time, hands-on learning, person-centered planning, supported decision-making

Acquired Brain Injury

What It Is: Damage to the brain occurring after birth from trauma, stroke, infection, lack of oxygen, or other causes.

Effects May Include: Changes to physical abilities, thinking, memory, communication, behavior, or emotional regulation

Understanding the Impact: Each brain injury is unique. Recovery is possible but often requires long-term support and rehabilitation.

Alzheimer's Disease and Dementia

What They Are: Progressive neurological conditions that affect memory, thinking, and behavior. Alzheimer's is the most common form of dementia, but there are other types including vascular dementia, Lewy body dementia, and frontotemporal dementia.

Characteristics:

  • Memory loss that disrupts daily life

  • Challenges in planning or solving problems

  • Difficulty completing familiar tasks

  • Confusion with time or place

  • Changes in mood and personality

  • Progressive decline over time

Understanding the Impact: Alzheimer's and dementia are disabilities under the ADA when symptoms substantially limit major life activities. In early stages, people may continue working and living independently with accommodations and support. As the condition progresses, more significant support becomes necessary.

Common Supports: In early stages: memory aids, routine structures, workplace accommodations (checklists, color-coding, extended training), supportive technology. Later stages: personal care assistance, specialized care environments, legal planning (advance directives, guardianship considerations).

Important Note: Early-onset Alzheimer's (diagnosed before age 65) qualifies for disability benefits. Families and individuals should understand their rights to workplace accommodations, healthcare access, and long-term support services.

Mental Health Conditions

What They Include:

  • Depression

  • Anxiety disorders

  • Bipolar disorder

  • Schizophrenia

  • Post-traumatic stress disorder (PTSD)

  • Obsessive-compulsive disorder (OCD)

Understanding the Impact: Mental health conditions are real disabilities that can significantly impact daily functioning. They are not character flaws or choices.

Common Supports: Therapy, medication, workplace accommodations, flexible schedules, reduced stress environments, crisis planning

Speech and Language Disorders

What They Are: Difficulties producing speech sounds, understanding language, or using language to communicate.

Types Include:

  • Articulation disorders

  • Fluency disorders (stuttering)

  • Voice disorders

  • Aphasia (language disorder following brain injury)

Common Supports: Speech therapy, communication devices, extra time for responses, alternative communication methods

Neurodevelopmental Motor Disorders

What They Include:

  • Developmental coordination disorder (dyspraxia)

  • Tic disorders

  • Tourette syndrome

Common Supports: Occupational therapy, physical therapy, understanding and patience, accommodations for motor challenges

Key Principles for Understanding

1. Disability is Natural Disability is a normal part of human diversity, not an oddity.

2. Disability ≠ Inability Having a disability doesn't mean someone is incapable. It means they may do things differently or need specific support.

3. The Social Model of Disability Many barriers disabled people face come from how society is designed, not from the disability itself.

4. Intersectionality Matters Disabled people have multiple identities (race, gender, sexuality, class) that interact and affect their experiences.

5. Presuming Competence Always assume people with disabilities are capable and have valid perspectives, even if they communicate differently.
