ADHD in women and girls: why late diagnosis is so common

ADHD has historically been seen as a condition affecting young boys - hyperactive, disruptive, struggling to sit still. That picture is both incomplete and damaging, particularly for women and girls who spend years or decades not understanding why they struggle in ways others seem not to.

Why ADHD looks different in women and girls

ADHD presents differently across individuals, but research consistently shows patterns that are more common in women and girls:

• Inattentive presentation is more common than hyperactive-impulsive ADHD and this is easier to miss because there are no external, disruptive symptoms
• Masking, many women and girls with ADHD develop strategies to hide their difficulties, at great personal cost
• Internalised struggles, anxiety, low self-esteem, and exhaustion from compensating are common, but these are often treated as primary conditions rather than as signs of underlying ADHD

The consequence: late diagnosis

The result of these patterns is that women and girls with ADHD are diagnosed, on average, significantly later than men and boys. Many are not diagnosed until adulthood, sometimes in their late 20s, 30s, 40s, or later. Some are never diagnosed at all, instead receiving diagnoses of anxiety, depression, or other conditions that treat the symptoms rather than the cause.

Late diagnosis is not that trivial. Years of not understanding why you struggle, why you are exhausted, why ordinary things feel harder than they should and that takes a real toll. Many women describe their ADHD diagnosis as both a relief and a grief: relief at finally having an explanation, and grief for the years spent without it. Many women have reported going through a period of feeling sad for their younger self and sometimes experiencing a form of skill regression - not being able to do some tasks and function in the same way they could before their diagnosis.

What to do if you think you might have ADHD

The first step for most people in Scotland is talking to your GP. You can ask to be referred for ADHD assessment. If your GP is unfamiliar with ADHD in adults or dismisses your concerns, you are entitled to ask for a second opinion or to request a referral.

You can also complete the self-screener on this site to get a clearer sense of whether your experiences match common ADHD presentations. It is not a diagnostic tool, but it can be a useful starting point for a conversation with your GP.

If NHS waiting times are long in your area which they likely are, the private assessment guide lists providers across Scotland with costs and assessment types. We understand you may not be able to do this financially, or that you feel you shouldn’t have to go private (which you shouldn't have to when we have an NHS that should help in a more timely manner but unfortunately is incredibly strained), but it can help you speed the process up of understanding yourself better and help you get the support you need.
