ADHD in Women and Girls: Why It Is So Often Missed
7 min read
Women with ADHD are diagnosed an average of 5–10 years later than men. A combination of symptom presentation differences, social masking, diagnostic bias, and a historical research base built primarily on hyperactive boys has left millions of women reaching adulthood without understanding the neurological basis of their struggles.
How ADHD presents differently in women
Women more commonly present with inattentive ADHD, which lacks the visible hyperactivity that triggers referrals. Compensatory strategies — perfectionism, over-preparation, internalised distress — mask functioning impairments. Emotional dysregulation is often the presenting symptom, leading to misdiagnoses of anxiety disorder, borderline personality disorder, or depression.
The masking phenomenon
Masking — the conscious and unconscious suppression of ADHD symptoms — is exhausting. Women with ADHD frequently report working twice as hard as peers to produce similar results, maintaining external order while experiencing inner chaos, and feeling profoundly misunderstood. The cost of chronic masking includes burnout, anxiety, and a persistent damaging sense of inadequacy.
Hormonal influences on ADHD
Oestrogen and progesterone directly modulate dopamine and norepinephrine — the neurotransmitters most affected by ADHD. Many women experience significant symptom fluctuations across their menstrual cycle. Perimenopause often triggers a dramatic worsening of previously manageable ADHD, sometimes resulting in a first-ever diagnosis in women in their 40s.
