Children who experience trauma when they are young may display autism-like behaviours that fit the timeline for an ASD diagnosis, which tends to occur around early school-age. In the absence of trauma-informed assessment, autism can sometimes be the default diagnosis.
However, autism spectrum disorder risk was increased in children of women who reported fear of partner or sexual, emotional, or physical abuse in the two years before the birth year (abuse in the year before the birth year, RR=1.58, 95% confidence interval (CI)= 1.04, 2.40; abuse in both of the two years before the ...
The risk of PTSD is higher for groups who are more likely to be exposed to traumatic events. Research indicates that autistic people may be more likely to experience traumatic life events, particularly interpersonal traumas such as bullying and physical and sexual abuse.
Although ASD and TBI present similar symptoms, there is no evidence that ASD is caused by trauma or injury to the brain. Its causes appear to be multifaceted and complex, including genetics, fetal conditions and various maternal and paternal factors.
However, autism symptoms can show up later in higher-functioning individuals when they're under more demand or challenge, making an adult autism diagnosis possible. In addition, some adults who were not diagnosed in childhood may be later diagnosed in adulthood.
not understanding social "rules", such as not talking over people. avoiding eye contact. getting too close to other people, or getting very upset if someone touches or gets too close to you. noticing small details, patterns, smells or sounds that others do not.
There are many different factors that have been identified that may make a child more likely to have ASD, including environmental, biologic, and genetic factors.
A recent study by Roberts et al. (2015) found a strong association between trauma, PTSD and autistic traits (which may have been sub-clinical) in adult women. This association was highest amongst those women with the most severe autistic traits.
There is no conclusive evidence that a fall can cause autism. However, some studies suggest that head injuries may be a risk factor for developing autism. It is important to note that not all head injuries lead to autism and that other factors may also play a role in the development of the disorder.
Childhood head injuries linked to increased risk of adult mental illness and poorer life chances. Childhood brain injuries, including concussions, are associated with an increased risk of subsequent mental illness, poor school attainment and premature death, according to a study published today in PLOS Medicine.
Though autistic people may respond to emotions and social cues differently than neurotypical people, this does not mean they lack empathy. Just like neurotypical people, levels of empathy vary between autistic individuals.
People with developmental, intellectual, psychiatric or learning differences can be considered neurodivergent. Neurodivergence is the state of being neurodivergent and can be genetic and innate (such as autism) or produced by experiences (such as trauma).
Both ADHD and ASD are neurodevelopmental disorders (brain development has been affected in some way). That means both conditions/disorders affect the central nervous system, which is responsible for movement, language, memory, and social and focusing skills.
Aggression in autism can involve severe tantrums, anger, hostility, sudden-onset violent outbursts including self-harm and rage 'episodes'. Up to 20% of individuals with autism exhibit such violent behaviours.
Every autistic person is different, but sensory differences, changes in routine, anxiety, and communication difficulties are common triggers.
Childhood disintegrative disorder.
This was the rarest and most severe part of the spectrum. It described children who develop normally and then quickly lose many social, language, and mental skills, usually between ages 2 and 4. Often, these children also developed a seizure disorder.
Due to the behavioural, information processing and sensory aspects of their diagnosis, many people on the autism spectrum often prefer familiar environments with a predictable routine. Restricted and repetitive interests, sensory processing differences and heightened anxiety can make even small changes stressful.
There is some evidence to suggest that brain damage caused by oxygen deprivation at birth may increase an infant's risk of developing disorders such as autism. A recent study in the US estimated that complications at birth may increase the risk of ASD in children by as much as 10%.
Some believe that autistic people aren't interested in romantic relationships or aren't capable of romantic love. However, this is far from the truth. In fact, autistic people can make wonderful partners.
Two such factors that have been associated with a significant proportion of ASD risk are prenatal stress exposure and maternal immune dysregulation. Maternal stress susceptibility appears to interact with prenatal stress exposure to affect offspring neurodevelopment.
Masking may involve suppressing certain behaviours we find soothing but that others think are 'weird', such as stimming or intense interests. It can also mean mimicking the behaviour of those around us, such as copying non-verbal behaviours, and developing complex social scripts to get by in social situations.
Advances in diagnostic capabilities and greater understanding and awareness of autism spectrum disorder seem to be largely driving the increase, the Rutgers researchers said. But there's probably more to the story: Genetic factors, and perhaps some environmental ones, too, might also be contributing to the trend.
Genetics. Genetic factors may be the most significant cause of autism. Early studies of twins had estimated heritability to be over 90%, meaning that genetics explains over 90% of whether a child will develop autism. This may be an overestimation, as later twin studies estimate the heritability at between 60 and 90%.
Due to its lower prevalence in females, autism was always thought to have a maternal inheritance component. However, research also suggests that the rarer variants associated with autism are mostly inherited from the father.
