Many autistic adults face further and vital limitations to analysis, with detrimental impacts.
Autistic adults who had been undiagnosed in childhood have reported a spread of adverse experiences related to their missed analysis, together with social isolation, diminished self-understanding, and insufficient psychological healthcare (Huang Y. et al, 2020; Leedham A. et al, 2020). Nevertheless, for a lot of late-diagnosed autistic adults, receiving an autism analysis brings a way of aid, self-acceptance, and improved administration of psychological and bodily well being circumstances (Lilley R. et al, 2022; Stagg SD & Belcher H, 2019).
Lately, researchers have sought to discover the limitations to autism analysis, significantly amongst adults. Inconsistent autism coaching amongst psychological well being professionals might contribute to autistic traits being missed or dismissed (Crane L. et al, 2019), particularly in traditionally under-diagnosed teams reminiscent of ladies and gender minorities. Moreover, overlapping traits between autism and circumstances reminiscent of Borderline Persona Dysfunction (BPD in DSM-5, also called Emotionally Unstable Persona Dysfunction in ICD-10) might contribute to misdiagnosis (Might T. et al, 2021) in these cohorts.
Tamilson, Eccles and Shaw (2024) discover the experiences of autistic adults who had beforehand acquired a analysis of BPD, to higher perceive the impacts of misdiagnosis.

Missed analysis, or misdiagnosis, can have detrimental impacts on anybody, however particularly on autistic adults.
Strategies
This was an interpretive phenomenological examine, framed inside a social constructionist paradigm – an applicable method for addressing the exploratory analysis questions.
Purposive sampling through social media promoting was used to recruit individuals who had been: English-speaking autistic adults (together with self-diagnosed) with a earlier analysis of BPD, positioned in the UK.
One-to-one semi-structured interviews had been performed and audio-recorded through Microsoft Groups. Interview questions had been knowledgeable by the researchers’ data, a literature evaluation, and people with related lived expertise.
Interpretive phenomenological evaluation (IPA) was used to generate detailed accounts of individuals’ particular person experiences, which had been then consolidated into group experiential themes.
Outcomes
Ten individuals had been interviewed (imply age = 34; 90% feminine, 10% questioning gender id). The typical age for receiving a BPD analysis was 22, and 29 for autism.
Ten group experiential themes had been constructed and sequenced to replicate the journey of individuals, beginning in youth:
- Struggles in early years
- Individuals all felt completely different from others and struggled to ‘slot in’ from an early age.
- Nevertheless, none had been identified as autistic in childhood.
- Missed analysis of autism
- Many felt their autism was missed due to gender bias and poor data about autism amongst psychological well being professionals.
- A recipe for misdiagnosis
- Individuals felt that psychological well being professionals readily misattributed their traits and experiences (e.g., self-harm, ‘autistic shutdowns’, signs of childhood trauma) to BPD.
- This impeded recognition of their autistic traits.
- Receiving a analysis of BPD
- BPD felt like a “lazy analysis” (P5) that was given “too readily” (P1).
- No uniform strategies had been recognized, within the assigning of this analysis – however individuals felt powerless to disagree with a analysis.
- It overshadowed their particular person wants and prevented applicable care.
- Disadvantages of receiving a BPD analysis
- Robust social stigma in direction of BPD, deeply impacted individuals’ self-perception, creating emotions of disgrace along with dissonance with their lived understanding of themselves.
- All individuals skilled difficulties accessing satisfactory psychological healthcare after the analysis.
- When providers had been accessed, they could possibly be dangerous and traumatic: individuals grew to become healthcare-avoidant, feeling dehumanised and stigmatised.
- Autism analysis
- Individuals who sought an autism analysis confronted limitations, together with professionals not believing them, delayed referrals, and lengthy wait instances.
- Prognosis with autism was related to expressions of aid, and self-perception that was not tied to BPD.
- Constructive points of autism analysis
- In distinction with the method of searching for analysis, receiving an autism analysis was described as positively “life-changing” (P2).
- Advantages included higher therapy from others, self-acceptance, improved psychological well being, and applicable lodging in schooling and employment.
- Individuals expressed experiencing much less ‘blame’ for his or her lived expertise, and extra validated in expressing their well being considerations.
- Adverse points of autism analysis
- Though individuals general skilled their autism analysis extra favourably than their BPD analysis, they nonetheless reported expertise of social stigma and ableism in schooling and healthcare settings.
- Reflections on diagnostic labelling
- Most paricipants thought of their BPD analysis was incorrect, reasonably than concurrent with autism.
- Nevertheless, BPD was described as a tough label to formally “do away with” (P10).
- Serving to others
- Individuals expressed a development mindset arising from their autism analysis, and reported their roles as advocates for others questioning their analysis, encouraging persistence when pursuing an autism analysis.

Though each Autism and BPD analysis led to experiences of stigma, individuals recognized with autism completely, not concurrent BPD.
Conclusions
By exploring the experiences of autistic adults beforehand, and sometimes incorrectly, identified with BPD, this examine revealed the substantial adverse impacts of missed analysis and misdiagnosis.
Individuals’ felt their autistic variations had been mischaracterised as BPD by psychological well being professionals because of gender bias, stereotypes and insufficient data about autism. Receiving a analysis of BPD had profound adverse impacts on their self-concept, strengthened by stigma and traumatic healthcare experiences.
Receiving an eventual autism analysis was described as ‘life-changing,’ enabling self-acceptance and applicable help. Tamilson and colleagues (2024) “name for improved autism coaching for psychiatrists” to stop misdiagnosis of autistic adults.

This examine provides to the name for psychiatrists to have larger diagnostic coaching for autism in adults.
Strengths and limitations
Strengths
This examine responds to a transparent group want and considers advantages for the autistic group from the outset.
Strengths of the examine embrace:
- Consistency within the chosen analysis paradigm (social constructionism), methodology (interpretive phenomenology and analytical method (IPA)); all of that are applicable for addressing the exploratory analysis query.
- The positionality of the analysis workforce was nicely described and contains related private {and professional} experience.
- Examine conceptualisation and improvement of the subject information had been knowledgeable by people with lived expertise.
- The sampling method and pattern dimension had been appropriate for IPA.
The inclusion of self-diagnosed autistic individuals was commendable – as this acknowledges the limitations to formal analysis skilled by a cohort historically excluded from analysis, whose views are extremely related to the examine goals and findings.
The ensuing themes are detailed, persistently supported by illustrative quotes, and complemented by figures that creatively characterize the info. The poem in Desk 2 humanises the info in a means that’s uncommon to see in analysis.
Limitations
Tamilson and colleagues acknowledge that the info assortment method might have been inaccessible to autistic people who find themselves non-speaking or uncomfortable with the social calls for of a web-based interview, that means that the distinctive views of such people had been seemingly excluded.
It seems that different interview approaches weren’t provided, which can be a logistical determination. Nevertheless, the authors don’t describe another efforts to enhance inclusivity, which creates a missed alternative for minoritised communities who they establish are extra liable to receiving a misdiagnosis. Tips to advertise inclusion of autistic adults in analysis (Nicolaidis C. et al, 2019) recommend lodging reminiscent of:
- Sharing the interview schedule upfront.
- Offering different interview codecs (e.g., e mail or textual content message).
- Permitting a help individual to be current.
These lodging can take away limitations to participation and enhance illustration of various autistic voices in analysis, and are a suggestion for researchers to think about in future tasks.
Clearly, with a 90% feminine pattern, the researchers may have achieved extra to incorporate a broader vary of individuals on this examine.
As this challenge was performed via self-selected survey participation, not a lot is understood relating to the diagnostic processes undergone by individuals in relation to both BPD or autism analysis, or how they are often improved. It could be of profit for a future examine to additionally search experiential qualitative information relating to psychological well being professionals’ views on diagnostic procedures and coaching in the identical geographical space to see if cross-comparison or standardisation is possible, preserving in thoughts the extra various inhabitants coming to searching for autism diagnoses in maturity.

This examine captures the lived expertise of some autistic adults. The expertise of suppliers stays to be captured.
Implications for follow
Missed analysis and misdiagnosis of autistic adults has garnered substantial consideration recently. Analysis exploring experiences of late autism analysis has proliferated prior to now ten years (e.g., Huang Y. et al, 2020; Leedham A. et al, 2020; Lilley R. et al, 2022; Lupindo BM. et al, 2023; Stagg SD & Belcher H, 2019), and trending social media content material about lived expertise of late- or self-diagnosis has introduced this matter into public discourse (Krouse L, 2022).
Every late-diagnosed autistic individual could have a singular perspective and expertise relating to their analysis. Nevertheless, the above literature reveals some widespread insights, which mirror the findings of this examine by Tamilson and colleagues, in addition to my very own expertise as a late-diagnosed autistic lady:
- Undiagnosed autistic individuals usually really feel completely different to others from a younger age, however might not perceive why. This may be detrimental to their psychological well being and self-perception.
- Many have felt their autistic traits had been missed or dismissed by psychological well being professionals, stopping well timed analysis and entry to needed care.
- Receiving an autism analysis usually brings a way of validation, aid, group, self-acceptance, and entry to lodging and applicable care.
This examine by Tamilson and colleagues extends upon the present literature by offering worthwhile new insights into the precise harms related to misdiagnosis of BPD amongst autistic adults. Although future cross-sectional analysis is required to find out the prevalence of this misdiagnosis and its related harms, I imagine the implications of those findings for medical follow can’t be understated. Analysis on this matter persistently signifies the need of higher autism coaching amongst psychological well being professionals, nevertheless, this examine illuminates the precise methods wherein gender bias and stereotyping of sure diagnostic labels can affect misdiagnosis and perpetuate hurt.
As such, coaching mustn’t solely goal to enhance medical data, however it should additionally problem biases and stereotypes relating to autism and diagnoses with overlapping traits, like BPD. Selling the variability inherent in autism, together with amongst ladies and gender minorities, might help extra nuanced approaches to differential analysis, stopping mislabelling and insufficient care.
Although the rationale for this examine is framed via the attitude of social justice for the autistic group, the implications for these identified with BPD and different circumstances really feel equally evident, as many individuals felt that they had been uncared for and mistreated in psychological well being settings because of structural stigma in direction of BPD. No matter their diagnostic label, everybody deserves entry to affirming psychological healthcare.

Stigma is usually a major barrier to accessing well timed and applicable psychological healthcare, which needs to be out there to all.
