Human beings rarely arrive one diagnosis at a time. Healthcare systems often do. Overlap is not a contest between labels.
Paradoxical.life began with medication transitions because that is where people are asked to reconstruct overlapping change from memory. Those transitions usually sit inside a larger problem: overlapping neurodevelopmental conditions, psychiatric comorbidity, sequential diagnosis, and the labour of navigating specialised healthcare systems.
Human beings rarely arrive one diagnosis at a time. Healthcare systems often do.
1 · Statement
ADHD and autism commonly co-occur. They were not formally allowed as co-diagnoses until DSM-5 (2013). Having one does not rule out the other, and treating one does not automatically treat the other.
2 · Classification
Established. Supported by expert consensus and by co-occurrence syntheses. Rates vary widely by sample.
3 · Papers
4 · Claim limitation
Clinic samples inflate co-occurrence. Co-occurrence is not identity.

ADHD, autism, dyslexia and related specific learning disorders, developmental coordination differences, language differences, and — where relevant — tic conditions, are intersecting presentations. They are not mutually exclusive. DSM-5 (2013) formally allowed ADHD and autism to be diagnosed together; the lives had been doing so already.
1 · Statement
Depression, anxiety, sleep disorders, OCD, trauma-related conditions, substance-use problems and eating disorders commonly co-occur with ADHD and/or autism. They may be separate, interacting, or both. A later developmental diagnosis does not mean the psychiatric diagnosis was imaginary.
2 · Classification
Established. Repeated in ADHD consensus, autism co-occurrence meta-analysis, and adult ADHD comorbidity reviews.
3 · Papers
4 · Claim limitation
Co-occurrence statistics do not tell you which condition is primary in an individual.

Not a collapse
Depression, anxiety, OCD, trauma-related conditions, sleep disorders, substance-use problems and eating disorders commonly co-occur. They may be separate, interacting, or both. A later developmental recognition does not mean the psychiatric diagnosis was imaginary.
1 · Statement
Bipolar disorder, borderline personality disorder and schizophrenia-spectrum disorders can share surface features with ADHD, autism, trauma or mood presentations. They can also coexist with neurodevelopmental conditions. They are not simply manifestations of neurodivergence. Correct differentiation can materially affect treatment.
2 · Classification
Established. Clinical consensus and comorbidity reviews. This is a caution about collapse, not a prevalence claim.
3 · Papers
4 · Claim limitation
Surface overlap does not tell you which model fits. This site will not choose.

Bipolar disorder, borderline personality disorder and schizophrenia-spectrum conditions require particularly careful differential diagnosis. Symptoms may overlap. Conditions may genuinely coexist. They are not simply manifestations of neurodivergence. Correct differentiation can materially affect treatment.
