Describe one biological explanation for autism. - AQA - A-Level Psychology - Question 12 - 2022 - Paper 2

One biological explanation for autism is linked to genetic factors. Research suggests that a variety of genes can interact to influence the development of the brain. For instance, it is believed that certain proteins produced by these genes may contribute to an increase in the number of neurons and an overgrowth of those neurons in the cortex. A specific gene identified in this context is the ADNP gene, which is thought to regulate the activity of other genes that are also believed to influence autism. This genetic interaction can affect neural development and ultimately impact behaviors associated with autism.
