What is defined as a major life activity?

A major life activity is an activity in which an individual engages numerous times, if not constantly, over the course of each day of the individual's life. Major life activities include caring for oneself, performing manual tasks, walking, seeing, hearing, speaking, breathing, learning and working, sitting, standing, lifting, reaching, and engaging in mental or emotional processes such as thinking, concentrating, and interacting with others. A substantial limitation of a major life activity means a person is unable to perform that activity at all or can only perform the activity in severely limited fashion compared to other individuals performing the same activity.

What are some common disabilities?

The physical and mental impairments that do substantially limit major life activities include a wide range of conditions. Some of the more common physical disabilities include hearing impairments, visual impairments, mobility impairments, multiple sclerosis, muscular dystrophy, chronic fatigue, immune dysfunction syndrome, Crohn's disease, and cardiac problems. Some types of physical impairment can be a disability or not depending on whether a major life activity is being limited. HIV, AIDS, and AIDS Related Complex can be disabilities, but commonly are not disabilities when treatments prevent the disease from limiting any major life activities. A mental impairment, to be considered a disability, must be diagnosed by mental health professionals as a condition that constitutes impairment of a major life activity. Many mental health conditions are impairments that do not substantially limit any major life activities. Manic depression, autism, apraxia, organic brain syndrome, and schizophrenia can all be disabilities, but only if the individual with the mental impairment is substantially limited in a major life activity due to the condition. Certain conditions are deemed by the law not to constitute disabilities under any circumstances: homosexuality; bisexuality; transvestism; transsexualism, pedophilia; exhibitionism; voyeurism; gender identity disorders not resulting from physical impairments; any other sexual behavior disorders; pyromania; compulsive gambling; kleptomania; current alcoholism; obesity; and psychoactive substance use disorders resulting from the current illegal use of drugs.

An individual can also be legally defined as disabled if the individual has a record of such impairment or is regarded as having such impairment. The first of these conditions is for individuals who have had an impairment that substantially limited a major life activity, but which no longer does. An example is an individual who has a history of cancer that is cured or in remission. Other individuals who may qualify under this condition include people with a prior history of mental illness, heart disease, or other treatable diseases. The second condition is for individuals who do not have an impairment that significantly limits a major life activity, but they have been mistakenly identified, classified, or treated as if they were disabled. Some examples of this condition include people being mistakenly treated as disabled for being a carrier of the Hepatitis B virus, having asymptotic HIV, or having minor physical ailments such as minor knee or back pains.
