ADHD and anxiety can occur together. They can also look similar: either may involve trouble concentrating, restlessness, irritability, or difficulty sleeping.
Understanding the pattern helps you get support for what is actually happening. Anxiety should not automatically explain away ADHD, and ADHD should not make an anxiety disorder invisible.
Ask about the history as well as the current symptoms. What has been present since childhood? What became harder during a particular period of stress? What happens when the situation becomes more manageable?
Lived Experience of ADHD and Anxiety
Your lived experience can help distinguish fear about a practical difficulty from a broader pattern of anxiety. Describe what you were facing, what you expected, and what happened when support or circumstances changed.
How ADHD and Anxiety Can Affect Each Other
ADHD-related difficulties can create reasons to worry. If you have missed appointments, lost important information, or been criticized for how you work, you may begin expecting another problem.
You might check repeatedly, arrive much too early, overprepare, or rely on worry to remember what needs doing. Those strategies may help you avoid some mistakes while using a great deal of energy.
Anxiety can also take up attention. Following a conversation is harder when part of your mind is rehearsing what might go wrong.
These patterns can overlap with an anxiety disorder. They are not two neat categories that everyone fits into.
What an Assessment Should Explore
Useful questions include:
- Were attention, organization, or activity-level differences present before the anxiety became prominent?
- Do they occur in several settings?
- Does concentration improve when the worry settles, or do difficulties remain?
- What happens during interesting activities and routine tasks?
- Are sleep, trauma, pain, medication effects, or other conditions contributing?
- What support has been tried, and what changed?
Screening questionnaires can help identify concerns, but an assessment needs more than a score. Masking and compensation can make some difficulties less visible. Missing ADHD is not the person’s fault. Young and colleagues’ expert consensus on ADHD in girls and women
What Is Generalized Anxiety Disorder?
Generalized anxiety disorder, or GAD, involves persistent, difficult-to-control worry about several areas of life. It may include feeling on edge, muscle tension, fatigue, poor concentration, irritability, and sleep problems. Diagnosis considers duration, distress, and interference with daily life. NIMH guide to GAD
GAD can occur alongside ADHD. It should not be reduced to worrying about missed deadlines.
A Canadian survey study by Fuller-Thomson and colleagues found an association between adult ADHD and GAD. It was published online in 2021 and in a 2022 journal issue. This was observational research: it could identify an association, but could not show that ADHD caused GAD. Group findings also cannot predict whether an individual woman will develop anxiety.

Anxiety Treatment Needs to Fit the Situation
Treatment may include psychotherapy, medication, and practical changes. For GAD, cognitive behavioral therapy can help people respond differently to persistent worry. NIMH treatment information
For an ADHD woman, the practical setup also needs attention. A plan that depends on remembering long instructions, completing extensive homework, or organizing several new routines may need to be adapted.
Examples include:
- written summaries after sessions
- one practice to try at a time
- reminders connected to the situation where the practice is needed
- shorter exercises
- time to review what made a strategy difficult to use
When fear reflects real criticism, discrimination, or an unsafe relationship, treatment should take that context seriously. Reducing worry cannot substitute for changing a harmful situation.
Which Should Be Treated First?
There is no rule that ADHD must always be treated first.
The plan depends on the severity of each condition, safety, what is most disruptive, previous treatment, and your preferences. Sometimes treatment addresses both together; sometimes one condition needs priority. The other should remain part of the plan. Expert consensus on assessment and treatment in females
Newer research supports an individualized approach. A 2025 review discusses prioritizing the most severe or unstable condition, then reassessing what difficulties remain. It does not support a blanket rule to treat ADHD first in every case. Fu and colleagues, 2025
Can ADHD Medication Affect Anxiety?
Responses vary. Some people feel less anxious when ADHD treatment makes daily demands more manageable. Others notice increased anxiety or other unwanted effects.
Anxiety during treatment does not by itself establish that the dose is too high. The prescriber can review the timing of symptoms, dose, formulation, sleep, other medicines or substances, and the underlying anxiety.
An anxiety diagnosis does not automatically rule out the usual ADHD medication options. NICE ADHD recommendations, section 1.7.18
A Useful Starting Point
Write down one recent anxious situation.
What was I worried would happen?
What made that concern understandable?
Was there a practical problem to solve, an anxiety pattern to work on, or both?
What support would reduce the demand?
