Why ADHD in Adults Is Often Missed

ADHD symptoms can change over time. Hyperactivity may become less obvious, while difficulties with focus, organisation, and emotional regulation often persist.

In the UK, many adults only seek assessment after years of struggling with stress, anxiety, or underperformance at work.

Common Signs of ADHD in Adults

ADHD traits vary, but here are some common indicators:

Attention and Focus Challenges

Difficulty concentrating on tasks, especially those that feel boring or repetitive.

Frequently losing items like keys, phone, or important documents.

Forgetting appointments or deadlines.

Impulsivity

Acting without thinking (e.g., impulsive spending, interrupting conversations).

Difficulty waiting in queues or during discussions.

Making quick decisions without considering consequences.

Hyperactivity and Restlessness

Feeling constantly “on the go” or unable to relax.

Talking excessively or switching topics rapidly.

Seeking stimulation through multiple projects or hobbies.

Emotional Regulation

Mood swings or frustration over small issues.

Feeling overwhelmed by stress or criticism.

Impact on Daily Life

ADHD in adults can affect careers, relationships, and mental health.

Many people experience low self-esteem or anxiety because they’ve struggled for years without understanding why.

When Should You Consider an ADHD Assessment?

If these traits have been present since childhood and significantly impact your life, an assessment may help.

In the UK, the process usually starts with your GP, who can refer you to a specialist. This may be via and NHS referral, an NHS ‘Right to Choose’ pathway, or you may take the decision to work with a private assessment centre.

NICE guidelines recommend a comprehensive evaluation, including developmental history and input from family or partners.
