A paper that combined several studies to confirm that they can co-exist, definitely so in my child (undiagnosed).

Through education I learned that emotional processing and sensory sensitivities were key in his case.
I was watching a video by Re-Active by Julie who mentioned that Clinicians should be screening for FND in Autism and Autism in FND.
If there were any clues that a person with Autism could be susceptible to FND then maybe they can be to taught how to regulate stressful situations in advance (have the tools/strategies to hand) and not develop FND.
It also mentioned other co-morbid conditions such as EDS. POTS and MCAS (also occur more commonly in autism) and they should be screened for too, so they can make sure they are treating the whole person/conditions.
It made me wonder how many people receive these other diagnoses years down the line.
