Why Should Autism Be Considered As an Innate Disorder?
by Albina Tskhay
Some studies show that both behavioral and clinical signs and symptoms of autism occur in the first months of a child's life (Dawson et al 2000; Steinman 2013).
In addition, some brain changes commonly seen in children with autism can only be initiated during fetal brain development. For example, children with autism have a reduced number of Purkinje cells (PK) in the absence of empty cavities. PCs only appear during the prenatal period, so this means that this disorder occurs in children before birth (Fatemi et al. Two thousand twelve)
It has been shown that even before birth, the brain volume of children who will be diagnosed with autism in the future, increased, indicating cerebral edema (Courchesne et al. 2007).
In one study, it was found that children under the age of 6 months who are at high risk are different from children in the control group. The pitch and frequency of the sound of these children crying differed significantly from each other.
There is an association between neonatal encephalitis (the same brain inflammation) and an increased risk of autism in the future (Fombonne 2006)
Another article analyzed home videos of 14 autistic and 10 neurotypical children during their first two years of life.. Based on the use of the final child behavior assessment (IBSE), this study confirms previous data and also shows the appearance of very early symptoms, perceptible during the first few months by psychologists who did not know whether the child has autism or not: an obedient quiet child who does not show obvious needs for contact, with no babbling.
