Ideally, a thorough diagnostic assessment involves two parts, a detailed developmental history and an observational assessment with the individual.
Details about early behaviour are crucial to gaining information to help make a diagnosis of Autism Spectrum Disorder. It is helpful to invite a parent, sibling or spouse to the assessment therefore. Whilst this information is more easily available from parents when assessing a child, it can often be difficult to obtain, or for parents to remember accurately, when assessing an adult. The use of family records or information can be helpful in such cases, or alternative assessment tools designed to gather relevant information may be used to help the clinician make a diagnosis.
Full written reports of the assessment results can be provided and a solution-focussed feedback session following assessment is also available.
Dr Powis and Dr Morrison may both be involved in the assessment process, to ensure a more rounded and reliable opinion.
