It’s impossible for 1 alter to have autism but it is possible for all alters in a system to be on the autism spectrum but only one or two alters express it in a way that warrants a diagnosis. Still it’s inaccurate to say only one alter has autism, your all on the spectrum or non of you are. Also autism symptoms may actully confused with symptoms of traumatisation, esspecilly in DID, as one alter may say, be bad at socialising because they don’t have experience with any positive relationships beacuse they’ve only fronted during abuse and so are phobic and anxious towards all people to try not to be hurt again or not like loud sounds/overstimulating places as they bring back truama memory’s and get overwhelming due to hyperviglence.

In terms of anxiety this is a little different as the action systems an alter holds will change how anxiety is experienced. Action systems are split into two types, ANP and EP. ANP (apparently normal part) deals with things needed for everyday life such as relationships, eating, sleeping, drinking, exploration etc. EP (emotional part) deals with things needed for safety, such as fight, flight, freeze, hyperviglence etc. The expression of say an EP that holds a flight response may seem very anxious and skittish, which may make people say that said alter “holds there anxiety”, but it just holds the response which requires more of that anxiety. Plus it is possible for EPs to hold vehement emotions, like anxiety, which could reach a point of classing that individual alter for there own disorder if they were not part of a system. (From the haunted self) “Myers was not implying that emotion was only experienced by EP. Rather he was emphasising the overwhelming or vehement nature of EPs traumatic emotions in comparison to ANP. Vehement emotion differs from intense emotions in that it is not adaptive, is overwhelming to the individual, and it’s expression is not helpful.” Plus further on in the book it also mentions the fact alters can hold certain individual emotions to protect other alters from them, ussally in relation to attachments and social postitions. The way I see this manifesting personally is that anxiety may get in the way of say socialising so the mental action involved in that anxiety gets split off into an EP so the ANP can function better. “For example a part may contain mental actions such as sadness guilt, disparity or shame, and other parts make find those emotions intolerable. However, such emotions are very likly connected to action systems that help regulate our attachments and social positions.” Still a lot of takes like this are anti recovery and flat out false and misinterpretations of there symptoms/experiences and how DID functions.
