A disability is a physical or mental condition that can often limit a person's senses, movement or everyday activities. A physical disability can often limit someone's mobility, speech, dexterity or stamina, such as brain and spinal cord injuries, cerebral pasly and multiple sclerosis. Physical disabilities also include chronic illnesses, such as endrometriosis or fibromyalgia. A chronic illness is one that has a long-lasting effect on the individual and impairs them from carrying out day to day activities.
Someone may still have a disability whether it is immediately noticeable or not. The term hidden disability refers to disabilities that might not be so noticeable to others, this includes neurodiversity, such as autism and ADHD, as well as hidden chronic illnesses.
