Adult ADHD

Attention deficit hyperactivity disorder (ADHD) doesn't go away as you grow up. In many adults it shows up as disorganisation, forgetfulness, difficulty finishing tasks, impulsivity or a constant sense of inner restlessness. Many people, especially women, are diagnosed for the first time as adults.

Common signs

• Frequent slips and forgetfulness in daily life
• Difficulty organising, planning and managing time
• Starting many things and finishing few
• Procrastination and getting stuck on long or boring tasks
• Impulsivity when speaking, buying or deciding
• Inner restlessness, needing to be doing something
• Rapid, intense emotional changes

Having some of these signs doesn't mean you have the disorder: only a professional can make a diagnosis.

Why does it happen?

It is a neurodevelopmental disorder with a strong genetic component. The difficulties are already there in childhood, although they are sometimes compensated for by intelligence, family structure or a lot of effort, and become visible when demands increase (university, work, children).

How is it diagnosed?

The diagnosis is made by a professional through a full assessment: a clinical and developmental-history interview, standardised questionnaires, tests of attention and executive functions, and information from people close to you. Other causes such as anxiety, depression, sleep problems or substance use need to be ruled out.

Treatment

Treatment combines psychoeducation, cognitive behavioural therapy focused on organisation, time management and emotional regulation and, when indicated, medication prescribed by psychiatry. Understanding how you work often relieves years of guilt.
