Distinguishing between ASD and other diagnoses can be challenging because the traits of ASD often overlap with symptoms of other disorders, and the characteristics of ASD make traditional diagnostic procedures difficult. [2] [3] Autism is associated with several genetic disorders, [4] perhaps due to an overlap in genetic causes. [5]
Differences in behavioral presentation and gender-stereotypes may make it more challenging to diagnose autism spectrum disorder in a timely manner in females. [19] [20] A notable percentage of autistic females may be misdiagnosed, diagnosed after a considerable delay, or not diagnosed at all. [20]
A 2019 analysis of perinatal and neonatal risk factors found that autism was associated with abnormal fetal positioning, umbilical cord complications, low 5-minute Apgar score, low birth weight and gestation duration, fetal distress, meconium aspiration syndrome, trauma or injury during birth, maternal hemorrhaging, multiple birth, feeding ...
ASD averages a 4.3:1 male-to-female ratio. The number of children diagnosed with the autism spectrum has increased dramatically since the 1980s, at least partly due to changes in diagnostic practice; it is unclear whether prevalence has actually increased; [3] and as-yet-unidentified environmental risk factors cannot be ruled out. [4]
Media portrayals of autism and violence negatively influence public opinion on autism [27] and foster negative impressions of autistic people by linking ASD with criminal behavior. [33] For example, an analysis of 100 French and Italian works of children's and young people's literature published between 1995 and 2005 featuring a main character ...
Autism spectrum disorder [a] (ASD), or simply autism, is a neurodevelopmental disorder "characterized by persistent deficits in social communication and social interaction across multiple contexts" and "restricted, repetitive patterns of behavior, interests, or activities". [11] Sensory abnormalities are also included in the diagnostic manuals ...
Trauma affects all children differently (see stress in early childhood). Some children who experience trauma develop significant and long-lasting problems, while others may have minimal symptoms and recover more quickly. [56] Studies have found that despite the broad impacts of trauma, children can and do recover with appropriate interventions.
In discussing the neurobiological basis for attachment and trauma symptoms in a seven-year twin study, it has been suggested that the roots of various forms of psychopathology, including RAD, borderline personality disorder (BPD), and post-traumatic stress disorder (PTSD), can be found in disturbances in affect regulation.
