Conditions comorbid to autism. Autism spectrum disorder (ASD) is a neurodevelopmental disorder that begins in early childhood, persists throughout adulthood, and affects two crucial areas of development: social communication and restricted, repetitive patterns of behavior. [ 1] There are many conditions comorbid to autism spectrum disorder such ...
Asperger syndrome ( AS ), also known as Asperger's syndrome or Asperger's, is a term formerly used to describe a neurodevelopmental condition characterized by significant difficulties in social interaction and nonverbal communication, along with restricted, repetitive patterns of behavior and interests.

Symmetry (geometry) A drawing of a butterfly with bilateral symmetry, with left and right sides as mirror images of each other. In geometry, an object has symmetry if there is an operation or transformation (such as translation, scaling, rotation or reflection) that maps the figure/object onto itself (i.e., the object has an invariance under ...
The weak central coherence theory ( WCC ), also called the central coherence theory ( CC ), suggests that a specific perceptual - cognitive style, loosely described as a limited ability to understand context or to "see the big picture", underlies the central issue in autism and related autism spectrum disorder.
Symmetry occurs not only in geometry, but also in other branches of mathematics. Symmetry is a type of invariance: the property that a mathematical object remains unchanged under a set of operations or transformations. [1] Given a structured object X of any sort, a symmetry is a mapping of the object onto itself which preserves the structure.
Autism, also called autism spectrum disorder [a] (ASD) or autism spectrum condition (ASC), [10] is a neurodevelopmental disorder characterized by symptoms of deficient reciprocal social communication and the presence of restricted, repetitive, and inflexible patterns of behavior that are impairing in multiple contexts and excessive or atypical to be developmentally and socioculturally ...
The pathophysiology of autism is the study of the physiological processes that cause or are otherwise associated with autism spectrum disorders . Autism's symptoms result from maturation-related changes in various systems of the brain. [1] How autism occurs is not yet well understood. Its mechanism can be divided into two areas: the ...
History of Asperger syndrome. Asperger syndrome (AS) was formerly a separate diagnosis under autism spectrum disorder. Under the DSM-5 and ICD-11, patients formerly diagnosable with Asperger syndrome are diagnosable with Autism Spectrum Disorder. The term is considered offensive by some autistic individuals. [ 1]
