ADHD vs Anxiety: How to Tell the Difference
ADHD and anxiety share so many symptoms — restlessness, poor concentration, trouble sleeping, feeling overwhelmed — that they're frequently misdiagnosed as each other. They also commonly occur together. Getting the right diagnosis is the difference between a treatment that works and one that makes things worse.

ADHD
Attention-Deficit/Hyperactivity Disorder — F90.9
ADHD is a neurodevelopmental disorder involving chronic difficulty with attention regulation, impulse control, and (in some subtypes) hyperactivity. It is caused by differences in dopamine and norepinephrine systems in the prefrontal cortex — not poor effort or motivation. ADHD typically begins in childhood and persists into adulthood.
Best for
- Difficulty sustaining attention even on interesting tasks
- Impulsivity, acting before thinking, interrupting others
- Chronic disorganization, time blindness, missed deadlines
- Hyperactivity or inner restlessness since childhood
- Symptoms present across multiple settings (work, home, relationships)
- Hyperfocus on highly stimulating tasks despite can't-focus elsewhere
Not ideal if
- Concentration difficulties only in high-stress or worry-filled situations
- Symptoms that began after a major life stressor
- Primarily fearful or catastrophic thinking patterns
Anxiety
Generalized Anxiety Disorder — F41.1
Anxiety disorders involve excessive, uncontrollable worry about future events — often accompanied by physical symptoms (heart racing, muscle tension, GI issues) and avoidance behaviors. Unlike ADHD, the concentration difficulty in anxiety is caused by worry consuming cognitive bandwidth, not an attention regulation deficit.
Best for
- Excessive worry about specific things (health, relationships, finances, performance)
- Physical symptoms: racing heart, tightness in chest, shallow breathing
- Avoidance of situations due to fear of something going wrong
- Catastrophic thinking and difficulty tolerating uncertainty
- Symptoms that worsen under stress and improve when relaxed
- Trouble concentrating only because mind is full of worry
Not ideal if
- Difficulty with attention when not worried (point to ADHD instead)
- Long history of impulsivity, disorganization from a young age
- Symptoms unrelated to worry or fear
Our Clinical Verdict
The key distinction: in ADHD, distraction is internal (mind wanders); in anxiety, distraction is worry-driven (mind races). Many people have both — getting both diagnosed matters.
Misdiagnosing ADHD as anxiety and treating only with SSRIs often fails — because SSRIs don't address the dopamine deficit underlying ADHD. Conversely, stimulants given to someone with pure anxiety can worsen their symptoms. A comprehensive psychiatric evaluation at Lyte Psychiatry screens for both conditions simultaneously, ruling out bipolar disorder and other conditions that can look like ADHD or anxiety. We use standardized rating scales (Conners, GAD-7, ASRS) alongside a clinical interview to get it right the first time.
Frequently Asked Questions
Can you have both ADHD and anxiety at the same time?
Yes — and it's very common. Studies suggest 50% of adults with ADHD also have an anxiety disorder. ADHD can cause secondary anxiety (anxiety from constantly underperforming, forgetting things, feeling overwhelmed). Both need to be treated for either to improve significantly.
How is ADHD diagnosed in adults in Texas?
Adult ADHD diagnosis involves a psychiatric interview assessing symptom history from childhood, standardized rating scales (ASRS-v1.1, Conners), and ruling out other causes. Lyte Psychiatry provides ADHD evaluations via telehealth across Texas — most patients receive a diagnosis in the first visit.
What medications treat ADHD vs anxiety?
ADHD is typically treated with stimulants (amphetamine salts, methylphenidate) or non-stimulants (atomoxetine, guanfacine). Anxiety is first-line treated with SSRIs/SNRIs. When both are present, treatment is sequenced carefully — often treating anxiety first, then adding ADHD medication once anxiety is controlled.
Does stimulant medication make anxiety worse?
It can in some patients, which is why proper diagnosis matters. In pure anxiety without ADHD, stimulants often worsen symptoms. In true ADHD with co-occurring anxiety, stimulants frequently reduce both — because reducing the ADHD-related chaos reduces the anxiety it was causing. A psychiatrist evaluates this individually.
