The relationship between autism and memory, specifically memory functions in relation to autism spectrum disorder (ASD), is an ongoing topic of research. ASD is a neurodevelopmental disorder characterised by social communication and interaction impairments, along with restricted and repetitive patterns of behavior. In this article, the word autism is used to refer to the whole range of conditions on the autism spectrum, which are not uncommon. Some of the earliest references to the topic of autism and memory dated back to the 1960s and 1970s, when several studies appeared proposing that autism should be classified as amnesia. What is now diagnosed as autism was formerly diagnosed as developmental amnesia. Although the views of autism as an amnesia of memory have now been rejected, there are still many studies done on the relationship between memory functions and autism. Autism can affect memory in complex and varied ways, with strengths and challenges depending on the individual. Many autistic people show strong semantic memory, excelling at recalling facts, details, or specific areas of interest, while episodic memory—recalling personal experiences, especially social or emotional ones—may be more difficult. Working memory, which involves holding and manipulating information short-term (Paytin), can also be weaker, particularly for verbal tasks. In contrast, visual and rote memory are often strengths, enabling some individuals to remember patterns, dates, or sequences with high accuracy. Although working memory difficulty is not part of the diagnostic criteria for ASD, it is widely recognized that autistic people commonly exhibit specific types of memory difficulties. These memory differences can influence daily life, learning, and social interactions, but vary widely across the autism spectrum. Further research is needed to get a fuller understanding of the relationship between autism and memory.
