Many women reach adulthood before anyone names their ADHD. In a CADDAC survey, 46% of Canadian women with ADHD said they first got a different diagnosis, often anxiety or depression. This guide explains why ADHD in women is often missed, and what the symptoms can look like.

Why ADHD can look different in women

ADHD research and diagnostic criteria were built mostly around how the condition shows up in boys, with visible hyperactivity. Many women have the inattentive type instead. The symptoms are quieter. They can look like disorganization, stress, or a busy life, not ADHD.

Many women also learn to mask their symptoms. They build routines and coping habits that hide the struggle underneath, especially at school and at work. The effort behind this masking can lead to exhaustion and burnout.

Common ADHD symptoms in women

ADHD can show up in many ways. Common symptoms include:

Trouble staying focused on tasks that are not interesting
Feeling easily overwhelmed by daily responsibilities
Starting many tasks but struggling to finish them
Losing track of time, appointments, or deadlines
Strong focus on topics that feel interesting or urgent
Misplacing items like keys, phones, or paperwork
Trouble falling asleep or waking up feeling rested
Symptoms that feel stronger around certain points in the menstrual cycle

Why women are often misdiagnosed

ADHD symptoms can overlap with anxiety and depression. A clinician who is not screening for ADHD can treat the overlapping symptoms without finding the root cause. Many women are also diagnosed only after a child in their family is assessed for ADHD, which prompts them to recognize the same patterns in themselves.

When to consider an assessment

If these symptoms sound familiar and they are affecting your work, relationships, or daily life, a clinical assessment can help you understand what is going on. See our guide on how an adult ADHD assessment works in Ontario to learn what to expect and how to book one.
