A severe, chronic disability that is attributable to a cognitive, neurological or physical impairment or a combination of cognitive, neurological and physical impairments; that is manifested during the developmental period (prior to age 22); that is likely to continue indefinitely; and that results in substantial functional limitations in three or more areas of major life activity including self-care, receptive and expressive language, learning, mobility, self-direction, capacity for independent living, and economic self-sufficiency.

A developmental disorder that affects communication and behavior, and includes symptoms that impair the individual's ability to function properly in school, work and other areas of life. Although autism can be diagnosed at any age, it is said to be a "developmental disorder" because symptoms generally appear in the first two years of life. Autism is also known as a "spectrum" disorder because there is wide variation in the type and severity of symptoms people experience. People with ASD have difficulty with social communication and interaction (e.g. lack of eye contact, voice tones that sound sing-song or robotic, facial expressions or gestures that don't match what is being said), restricted interests (e.g., intense interest in numbers, details, facts), restrictive/repetitive behavior (e.g., repeating words or phrases, getting upset at changes in routine or sensory input such as light or noise). People with ASD may also experience sleep problems or irritability, but also have many strengths including the ability to learn things in detail and remember information for long periods of time; being strong visual and auditory learners; and excelling in math, science, music or art. But although ASD can be a lifelong disorder and while children who have ASD have difficulty in talking, playing with other children, and relating to others, including their own family, treatment and services can improve their symptoms and ability to function.

A disorder arising in childhood or adolescence which is marked by an inability to learn or other functional deficits that cannot be explained by intellectual, sensory or health factors; an inability to build or maintain satisfactory interpersonal relationships with peers, teachers and other adults; inappropriate types of behavior or feelings under normal circumstances; a general pervasive mood of unhappiness or depression; and a tendency to develop physical fears associated with school problems or other issues that is severe enough to adversely affect the child's educational performance or ability to engage in age-appropriate activities. Characteristics may include hyperactivity, aggression or self-injurious behavior, withdrawal, immaturity, and learning difficulties.

Individual practitioners, programs, and/or systems whose approach to engaging people with a history of trauma involves recognition of the presence of trauma symptoms and acknowledgement of the role that trauma has played in their lives. The approach can be implemented in any type of service setting or organization and has been used in the delivery of a broad range of services including mental health, substance use, housing, vocational or employment support, domestic violence and victim assistance, and peer support. However, it is distinct from trauma-specific interventions or treatments that are designed specifically to address the consequences of trauma and to facilitate healing.
