In recent decades, clinicians and researchers have become increasingly aware of a form of extreme social withdrawal lasting at least six months, known as hikikomori [ 1 ]. The term was coined in the late 1990s by Japanese psychiatrist Saitō Tamaki to describe individuals who withdraw almost entirely from social life, isolating themselves within their home – often in a single room – refusing school or work, and avoiding face-to-face relationships. While some remain connected t

Autism has long been described as a lifelong neurodevelopmental disorder/condition. Core behavioural features, typically emerging in infancy or early childhood, have been assumed to persist throughout the lifespan. The research, however, suggests that within the vast heterogeneity of autism , not all individuals follow a single, fixed trajectory. Various reports have documented the presentation of " acquired autism " ( regression ) following a period of typical development.

This post continues a critical analysis of a list of memes titled What Not to Say to an Autistic Person . The first “not to” – “You don’t look autistic”  – was examined in the previous post . Here, we turn to two further entries on that list: “ We’re all on the spectrum ”  and “ Everyone is a bit autisti c .” Both statements are routinely dismissed as ignorant and/or offensive. Yet their persistence suggests that something more than simple misunderstanding is at work. These p

How Research on “Frank” Autism Undermines a Persistent and Harmful Meme With a few friends, I have started working on a project that may be seen as controversial but feels deeply important to those of us who live with the consequences of how autism is constantly redefined, reframed, and repackaged online[ 1 ]. We decided to start small—by analysing the memes that circulate endlessly across social media—and then follow the discussion wherever it leads us. When I looked at a li

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
