A Simplification That Simplifies Nothing The 5 th  edition, published in 2013, set out to simplify and modernise the nosology of autism-related disorders, replacing the DSM-IV’s cluster of Pervasive Developmental Disorders (PDDs) — Autistic Disorder, Asperger’s Disorder, Childhood Disintegrative Disorder, Rett’s Disorder [ 1 ] and PDD-Not Otherwise Specified (PDD-NOS) — with a single diagnosis: Autism Spectrum Disorder (ASD). The intent was, in principle, laudable: a spectrum

The question of how stable an autism diagnosis is over time has long been debated. While many families and clinicians view an autism diagnosis as lifelong, research suggests that diagnostic stability—how consistently a diagnosis persists over time—depends heavily on which diagnostic framework is used. Emerging evidence indicates that before the introduction of the broader ASD category in the DSM-5  (APA 2013), autism diagnoses were more stable and predictable. Before DSM-5: D

In most cases, ASD is diagnosed between 15 and 30 months. Some children exhibit typical early development, only to lose acquired language and social skills between 15 and 30 months. These cases qualify as regressive autism. However, there are instances of late onset autism where individuals appear to develop typically until adolescence or even adulthood before displaying symptoms consistent with autism. In such cases, an identifiable neurological insult, such as, e.g, herpes

Alexithymia is considered a “sub-clinical phenomenon” (Silani et al. 2008) and doesn’t identify a personality disorder  per se  but is a personality trait that is dimensional in nature (Taylor et al. 1991). Alexithymia is not a symptom of autism, but rather an independent construct that frequently co-occurs with autism. Although alexithymia has similar symptoms , it is distinct from autism – it is neither a necessary nor sufficient feature for an autism diagnosis, and there a

The connection between alexithymia and ASD was initially explored in the 1990s through clinical studies on individuals with eating disorders, specifically anorexia nervosa (AN).   The studies revealed the co-occurrence of eating disorders with deficiencies in social competence and identified some traits that were considered typical of ASD, [ 1 ]   such as empathy problems, as well as some features considered typical of alexithymia, such as difficulty verbalising emotions, ide

- Hello, where are you? - I am at home. - At home? Where? - I have one home, in England. Why? What’s happened? - Why did you leave without saying ‘goodbye’? It was great when you and your daughter came to see me. We visited friends and had fun. I was preparing your farewell party, but you left. You could have said goodbye… Thus began my conversation with my childhood friend (B.). We have be
