Research indicates that genetic factors predominate. For example, mutations in the ADNP gene cause a disorder called ADNP syndrome. 2016 Learn about the brain anatomy of individuals with autism spectrum disorder including how brain volume differs in children with ASD and various brain structures that are impacted by ASD. These studies suggest that autism may be caused by abnormal neuronal growth and pruning during the early stages of prenatal and postnatal brain development, leaving some areas of the brain with too many neurons and other areas with too few neurons. However, fluent speakers with ASD often have problems associated with verbal communication. Children, whose brother, sister and/or parent has an autism spectrum disorder is at greater risk for one of these disorders.

According to the National Human Genome Research Institute (NIH), CNV occurs when there is a variation in the number of copies of certain genes expressed in DNA from person to person. An international study conducted out of the U.K. by Cardiff University shows that many people with genetic conditions and autism symptoms cannot easily get a formal autism diagnosis. The gains and losses of genetic material has been associated with an increased risk in certain diseases and conditions, including autism, although research is ongoing.

How can gene mutations affect health and development? ASD has a tendency to run in families, but the inheritance pattern is usually unknown. However, as autism is a spectrum disorder, the severity of the disorder may differ from mild to moderate and to severe. What are the different ways in which a genetic condition can be inherited? Inability to recognize and use these cues makes it hard for affected individuals to understand the feelings of others or communicate their own feelings appropriately. theories and diagnosis. Pervasive development disorder or atypical autism: People with atypical autism have only social and communication-related issues.

Various neuropathological and MRI studies have pointed to a number of neurological abnormalities in autism: 1. These abnormalities are thought to underlie the differences in socialization, communication, and cognitive functioning characteristic of ASD. Comparatively, the prevalence of autism in the general public is only 1%. They may also have difficulty tolerating sensory stimuli such as loud noises or bright lights. 10.1007/s12098-016-2080-8.

Even if a caregiver suspects autism but is unable to get a diagnosis, there are ways to pursue early intervention. Some affect the number of neurons that are produced, while others are involved in the development or function of the connections between neurons (synapses) where cell-to-cell communication takes place, or of the cell projections (dendrites) that carry signals received at the synapses to the body of the neuron.
