The Lyceum

The diagnosis that came thirty years late

Specialist CBT therapy for anxiety, OCD, depression and more in West London

Sometimes people look back on years of feeling different, overwhelmed, disorganised, intensely focused, ashamed or misunderstood and wonder whether a diagnosis might explain it. Late recognition can bring many feelings: curiosity, relief, grief, anger, uncertainty or none of these. A blog cannot diagnose ADHD or any other condition, explain a person’s history, or say whether an assessment will provide a clear answer. ADHD is a neurodevelopmental condition that requires appropriate assessment. It should not be self diagnosed from a personal story, a list of traits, a social media post or a difficult period. Similar experiences can arise in different contexts, including anxiety, low mood, sleep disruption, trauma, physical health, practical pressures, neurodivergence and ordinary variation. A later assessment can still be meaningful, but it is not a measure of whether someone deserved help sooner or whether the past should have looked different. It can consider history, functional impact, health information, strengths, current support and other explanations. It may also leave some questions open. CBT may be considered after assessment where appropriate. It is not a substitute for diagnosis, medical advice, workplace advice or medication conversations. Where CBT informed work is suitable, it is developed collaboratively with a qualified clinician and adapted to the person’s goals, capacity, sensory needs and circumstances. There is no promise that therapy will produce a particular diagnosis, feeling or outcome. Support may involve a GP, a specialist assessment service, occupational health, workplace or education support, practical adjustments, trusted people, medication discussions or rest. No single pathway is right for everyone. It can help to bring a few examples to an assessment conversation: a pattern that has been difficult since childhood, a recent situation that feels different, a strength that gets overlooked, a work or home pressure, or a question that has stayed unanswered. These examples are not evidence that a diagnosis will follow. They give a fuller picture and can help identify what support, information or next step may be most relevant. Being uncertain does not make the question less legitimate. It may simply mean more careful listening is needed, first and foremost, together.

If distress includes crisis, thoughts of self harm or an inability to keep safe, urgent appropriate help is needed.

Frequently asked questions

Does recognising ADHD traits mean I have ADHD?

Not necessarily. ADHD requires appropriate assessment, and similar experiences can have different explanations.

Is it too late to seek an assessment?

A blog cannot decide what is right for one person, but an appropriate professional can discuss current options and context.

Can CBT give me an ADHD diagnosis?

No. CBT is not a diagnostic assessment. It may be considered after assessment where appropriate.

When should I seek urgent help?

Seek urgent appropriate help if distress includes crisis, thoughts of self harm or an inability to keep yourself safe.
