It is very likely that the diagnosis of ASD or ADHD can be delayed in a child when the two conditions co-occur, than when the child presents just one condition (ASD or ADHD). This is because on the surface it is possible to mistake one condition for another due to a fair degree of overlap in the child's behavioral symptoms. For example, when a parent finds it difficult to have a conversation with their child it is very easy to mistake his/her lack of attention in a social setting for a deficit in social communication skills (or vice versa). However, understanding the underlying cause of your child's behaviour is key to seeking the most appropriate medical intervention at the earliest. Please use this printable infographic to help understand the two conditions in a setting where they can co-occur in a child. You may use this as a stepping stone to delve further into understanding your child's unique requirements.
