#believe or not have seen late/no dx LSN autistic say regressive autism no exist because it just parents ignore autism symptoms 🥰

[five-thousand-loaves-of-bread]

am have to late autism regression that began late adolescence, but am don’t have “regressive autism.”

regressive autism is where child look develop normally, but at usually 15-30 months old, lose social skills, language & speech, and sometimes other skills, like motor skills and adaptive skills. this where before, child vocalizing babbling talking and interacting, and suddenly or slowly, stop talking stop responding to people (so no, it not “evil ableist parents ignore autism symptom🙃”). we no know why yet. also, child with regressive autism typically more severe symptom than child with non-regressive autism. [source]

even though many people here on tumblr seem have autism regression in teenage or early adult, “autistic regression” actually more common refer to this before-age-3 regression. other names include developmental regression. —which why when talk about own regression, typically on purpose add “late” autism regression. late autism regression is actually considered rare (whether because rarely studied rarely diagnosed, or actually rare in number, don’t know).

whether have late regression or not, need all be mindful that regressive autism & autism regression before 3 exist and not ignore or drown out it. need remember those with regressive autism, most won’t be able be here on tumblr talk about it, because well, they 3, it happen at 3. even if they older now, their severity of symptom mean many not able communicate about it or use social media. because of this, many people talk about this going to be parents of child with regressive autism.

ICD-11 recognize both regression before 3 (what am talk about here with regressive autism) and after 3. ICD-11 diagnosis of autism have modifiers (DSM also do but a little different modifiers): comorbid disorder of intellectual development (aka intellectual disability), degree of functional language impairment, and “loss of previously acquired skills,” aka regression.

A small proportion of individuals with Autism Spectrum Disorder may present with a loss of previously acquired skills. This regression typically occurs during the second year of life and most often involves language use and social responsiveness. Loss of previously acquired skills is rarely observed after 3 years of age. If it occurs after age 3, it is more likely to involve loss of cognitive and adaptive skills (e.g., loss of bowel and bladder control, impaired sleep), regression of language and social abilities, as well as increasing emotional and behavioural disturbances.

.

with either regression before 3 or after 3, include late adolescents regression, important to rule out all other causes. because other reasons that make look regression may be life threatening disorders.

regression also see in child disintegrative disorder (CDD), rett syndrome, and some others. they all a little different, timing, symptoms, etc.

do not debate “severity” of autism language here. do not use this to self diagnose. do not use this to talk about parental trauma or debate autism parents & parents of autistics.
