Autism spectrum disorder in the context of "Nonverbal autism"

Speech–language pathology, also known as speech and language pathology or logopedics, is a healthcare and academic discipline concerning the evaluation, treatment, and prevention of communication disorders, including expressive and mixed receptive-expressive language disorders, voice disorders, speech sound disorders, speech disfluency, pragmatic language impairments, and social communication difficulties, as well as swallowing disorders across the lifespan. It is an allied health profession regulated by professional state licensing boards in the United States of America, and Speech Pathology Australia. The American Speech-Language-Hearing Association (ASHA) monitors state laws, lobbies & advocates for SLPs. The field of speech-language pathology is practiced by a clinician known as a speech–language pathologist (SLP) or a speech and language therapist (SLT). SLPs also play an important role in the screening, diagnosis, and treatment of autism spectrum disorder (ASD), often in collaboration with pediatricians and psychologists.

Special education (also known as special-needs education, aided education, alternative provision, exceptional student education, special ed., SDC, and SPED) is the practice of educating students in a way that accommodates their individual differences, disabilities, and special needs. This involves the individually planned and systematically monitored arrangement of teaching procedures, adapted equipment and materials, and accessible settings. These interventions are designed to help individuals with special needs achieve a higher level of personal self-sufficiency and success in school and in their community, which may not be available if the student were only given access to a typical classroom education.

Special education aims to provide accommodated education for students with disabilities such as learning disabilities, learning difficulties (such as dyslexia), communication disorders, emotional and behavioral disorders, physical disabilities (such as osteogenesis imperfecta, down syndrome, lissencephaly, Sanfilippo syndrome, and muscular dystrophy), developmental disabilities (such as autism spectrum disorder, and intellectual disabilities) and other disabilities. Students with disabilities are likely to benefit from additional educational services such as different approaches to teaching, the use of technology, a specifically adapted teaching area, a resource room, or a separate classroom.

Child psychopathology refers to the scientific study of mental disorders in children and adolescents. Oppositional defiant disorder, attention-deficit hyperactivity disorder, and autism spectrum disorder are examples of psychopathology that are typically first diagnosed during childhood. Mental health providers who work with children and adolescents are informed by research in developmental psychology, clinical child psychology, and family systems. Lists of child and adult mental disorders can be found in the International Statistical Classification of Diseases and Related Health Problems, 10th Edition (ICD-10), published by the World Health Organization (WHO) and in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), published by the American Psychiatric Association (APA). In addition, the Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood (DC: 0-3R) is used in assessing mental health and developmental disorders in children up to age five.

Hyperfocus is an intense form of mental concentration or visualization that focuses consciousness on a subject, topic, or task. In some individuals, various subjects or topics may also include daydreams, concepts, fiction, the imagination, and other objects of the mind. Hyperfocus on a certain subject can cause side-tracking away from assigned or important tasks.

Psychiatrically, it is considered to be a trait of attention deficit hyperactivity disorder (ADHD) together with inattention, and it has been proposed as a trait of other conditions, such as schizophrenia and autism spectrum disorder (ASD).

Special education (special ed. or SPED), also known as special-needs education, aided education, alternative provision, exceptional student education, or special day class (SDC), is the practice of educating students in a way that accommodates their individual differences, disabilities, and special needs. This involves the individually planned and systematically monitored arrangement of teaching procedures, adapted equipment and materials, and accessible settings. These interventions are designed to help individuals with special needs achieve a higher level of personal self-sufficiency and success in school and in their community, which may not be available if the student were only given access to a typical classroom education.

Students with disabilities are likely to benefit from additional educational services such as different approaches to teaching, the use of technology, a specifically adapted teaching area, a resource room, or a separate classroom.

A spectrum disorder is, in psychiatry, a disorder that includes a range of linked conditions, sometimes also extending to include singular symptoms and traits. The different elements of a spectrum either have a similar appearance or are thought to be caused by the same underlying mechanism. In either case, a spectrum approach is taken because there appears to be "not a unitary disorder but rather a syndrome composed of subgroups". The spectrum may represent a range of severity, comprising relatively "severe" mental disorders through to relatively "mild and nonclinical deficits". The term "spectrum disorder" is heavily used in psychiatry and psychology, but has also seen adoption in other areas of medicine, for example hypermobility spectrum disorder and neuromyelitis optica spectrum disorder.

In some cases, a spectrum approach joins conditions that were previously considered separately. A notable example of this trend is the autism spectrum, where conditions on this spectrum may now all be referred to as autism spectrum disorders, and in the DSM-5 were unified into a single autism spectrum disorder (ASD). A spectrum approach may also expand the type or the severity of issues which are included, which may lessen the gap with other diagnoses or with what is considered "normal". Proponents of this approach argue that it is in line with evidence of gradations in the type or severity of symptoms in the general population.
