When Anxiety Isn’t Just Anxiety: Understanding ADHD in Women

If your mind never seems to shut off, it’s easy to assume you have anxiety—but that may not be the full story. For many women, what appears as anxiety is actually undiagnosed Attention-Deficit/Hyperactivity Disorder (ADHD). This is particularly true given that women often experience ADHD differently than men, leading to frequent misdiagnosis and delayed treatment.

The Overlap and the Misdiagnosis

Historically, ADHD research focused primarily on boys, resulting in a limited understanding of how the condition manifests in women. Generations of women have been overlooked, often receiving diagnoses of anxiety or other mood disorders instead. This misdiagnosis can lead to years—even decades—of ineffective treatment. The core issue is that ADHD in women often presents differently than the stereotypical image of a hyperactive boy; it frequently manifests as internal restlessness, overthinking, perfectionism, and emotional overwhelm.

In clinical practice, it’s common to witness women who have been treated for anxiety for years without significant relief. This isn’t because they aren’t trying hard enough, but because the underlying cause may not be anxiety at all. Instead of outward hyperactivity, ADHD in women often presents as a constant internal “motor”: relentless planning, scanning for potential problems, worrying, and anticipating needs.

How ADHD and Anxiety Overlap

ADHD and anxiety share several overlapping symptoms, making differentiation challenging. These include:

• Restlessness
• Difficulty concentrating
• Racing thoughts
• Sleep disruption
• Irritability
• A persistent sense of overwhelm

However, while these symptoms may feel similar, the underlying drivers are different. Anxiety is typically rooted in a threat-based response, with the brain scanning for danger and focusing on fear, uncertainty, and worst-case scenarios. ADHD, is more closely tied to differences in attention regulation and reward processing. When the brain struggles to filter, prioritize, and shift attention, thoughts can become overwhelming, but this is less about fear and more about cognitive load – too much input and insufficient sorting.

Key Differences: Anxiety vs. ADHD

Understanding the distinction often comes down to patterns. With anxiety, worry is usually tied to perceived threats and tends to ease when those threats are resolved or reassurance is provided. With ADHD, the sense of urgency or mental noise often improves when interest is introduced or when the task becomes engaging. ADHD-related distress is often responsive to dopamine; a shift in stimulation, novelty, or focus can bring noticeable relief, which is not typical with anxiety.

The content of the thoughts also differs. Anxiety tends to center on fear—something bad happening or going wrong. ADHD-related worry is often more practical but equally relentless: forgetting something important, missing a step, falling behind, or feeling overwhelmed by tasks.

Neurologically, anxiety is associated with heightened threat detection systems, while ADHD reflects differences in executive functioning and frontostriatal dopamine pathways. Both can involve hyperarousal, but the source—and therefore the most effective intervention—can be quite different.

Why Women Are Often Overlooked

ADHD in women is frequently missed because it doesn’t align with the traditional understanding of the disorder. Instead of being disruptive, many women become highly adaptive and overfunction, compensating to hold everything together until they can no longer cope. This can lead to internal struggles such as chronic self-doubt, mental exhaustion, emotional overwhelm, and a persistent feeling of working harder than everyone else. This often contributes to imposter syndrome, where women appear capable but internally experience significant distress.

Research from the Pew Research Center demonstrates that women continue to shoulder a disproportionate share of household and caregiving responsibilities, even when working comparable hours to their partners. This increased mental load can exacerbate ADHD symptoms and contribute to misdiagnosis.

The Consequences of Misdiagnosis and What We Need Now

When ADHD is misdiagnosed as anxiety alone, women may develop unhelpful coping strategies, such as overworking, emotional eating, or substance utilize, to manage their symptoms. Over time, this can affect both mental and physical health, leading to chronic stress, sleep disruption, and exhaustion.

An accurate ADHD diagnosis can be transformative. Treatment may include medication, but it also involves learning to work with your brain—through structure, support, and intentionally building in activities that regulate attention and energy. With understanding, women can begin to let go of masking and overcompensating, leading to reduced strain and improved well-being.
