Childhood diagnoses in individuals identified as autistics in adulthood / E. M. RØDGAARD in Molecular Autism, 12 (2021)
[article]
Titre : Childhood diagnoses in individuals identified as autistics in adulthood Type de document : Texte imprimé et/ou numérique Auteurs : E. M. RØDGAARD, Auteur ; K. JENSEN, Auteur ; K. W. MISKOWIAK, Auteur ; L. MOTTRON, Auteur Article en page(s) : 73 p. Langues : Anglais (eng) Mots-clés : Adult Autism Comorbidity Late diagnosis A/S in the past three years. EMR, KJ, and LM declare no competing interests. Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism is a developmental condition, where symptoms are expected to occur in childhood, but a significant number of individuals are diagnosed with autism for the first time in adulthood. Here, we examine diagnoses given in childhood among individuals that are diagnosed with autism in adulthood, to investigate whether the late autism diagnosis might be explained by misdiagnosis in childhood or diagnostic overshadowing. METHODS: Through the Danish National Patient Registry, we identified individuals diagnosed with autism in adulthood (N?=?2199), as well as a control sample with no records of an autism diagnosis (N?=?460,798) and calculated how many had received different psychiatric or neurological diagnoses in childhood. RESULTS: We found that most childhood diagnoses were overrepresented in those with an adult autism diagnosis, and attention-deficit hyperactivity disorder, affective disorders, anxiety, and stress disorders were the most prevalent childhood conditions in this group. However, 69% of males and 61% of females with adult autism diagnoses were not found to have received any of the investigated diagnoses before 18 years of age, and most childhood diagnoses were given after the age of 12. LIMITATIONS: Milder to moderate cases of psychiatric conditions that have been solely treated by family physicians or school psychologists may not be fully included in our dataset. The study is based on data from the Danish health care system, and further research is needed to assess whether the findings can be generalized to other countries. CONCLUSION: A majority of those with an adult autism diagnosis had no records of having received any of the investigated diagnoses in childhood. In these cases, the late autism diagnosis is therefore unlikely to be explained by either misdiagnosis or overshadowing. This result is at odds with the prevailing notion that autistic symptoms tend to diminish with age. Therefore, further research is warranted to examine how and if early signs of autism may have manifested among these individuals, and how similar they are to autistic people diagnosed earlier in their development.
