Aphasia is a neurodivergent condition, a language disorder, that is sometimes a co-occurring condition for autistic people, as well as many other neurodivergent groups, such as people who have had strokes and people with dementia. It relates to losing the ability to recall, use and understand certain words, in speech and in writing. This can be a permanent change or it can occur in specific environments, particularly anxiety-inducing ones. It also co-occurs with apraxia of speech.
