“…Potential mechanisms underlying the relationship between AN and autism could include shared cognitive traits: commonly with research in autism, literature shows that people with AN exhibit problems with rigidity, central coherence, and emotional and social processing that may persist following recovery (Harrison, Mountford, & Tchanturia, 2014;Lang, Lopez, Stahl, Tchanturia, & Treasure, 2014;Katie Lang et al, 2016;Leppanen, Sedgewick, Treasure, & Tchanturia, 2018;Westwood, Lawrence, Fleming, & Tchanturia, 2016;Westwood, Stahl, Mandy, & Tchanturia, 2016).
