ADHD vs. Anxiety vs. Depression: How to Tell the Difference and Get the Right Diagnosis
Difficulty concentrating. Low motivation. Feeling overwhelmed. Emotional exhaustion.
These symptoms are incredibly common — and they can point to ADHD, anxiety, depression, or a combination of all three. Because these conditions share many overlapping features, misdiagnosis is common, especially in adults.
Understanding the differences between ADHD, anxiety, and depression is one of the most important steps toward getting the right diagnosis and the right treatment.
This guide explains how clinicians distinguish these conditions — and how adults in North Carolina and Maryland can pursue accurate diagnosis through professional telehealth care.
Why ADHD, Anxiety, and Depression Are Often Confused
These three conditions overlap in several key ways:
Difficulty concentrating
Mental fatigue
Low motivation
Trouble completing tasks
Emotional distress
It’s also common for people to have more than one condition at the same time, which further complicates diagnosis.
This is why online quizzes and self-diagnosis are often misleading — and why professional evaluation matters.
Key Signs of ADHD in Adults
Adult ADHD is primarily a disorder of attention and executive functioning.
Attention and Focus Patterns
Common signs include:
Difficulty sustaining focus
Trouble starting or finishing tasks
Frequent distraction
Losing track of time
Executive Function Challenges
These may include:
Chronic disorganization
Difficulty prioritizing
Poor time management
Feeling overwhelmed by planning
Lifelong Pattern
One of the most important diagnostic clues is history.
In ADHD:
Symptoms usually begin in childhood
Difficulties persist across school, work, and home
Challenges are consistent over time
Key Signs of Anxiety
Anxiety is primarily driven by excessive worry and physiological arousal.
Core Anxiety Features
Common symptoms include:
Persistent worry
Racing thoughts
Muscle tension
Restlessness
Difficulty relaxing
How Anxiety Affects Focus
With anxiety:
Focus is disrupted by worry
Attention improves when anxiety decreases
Symptoms often fluctuate with stress levels
Key Signs of Depression
Depression is primarily a disorder of mood and motivation.
Core Depression Features
Common symptoms include:
Persistent low mood
Loss of interest or pleasure
Feelings of hopelessness
Changes in sleep or appetite
Cognitive Effects of Depression
These may include:
Brain fog
Slowed thinking
Low energy
Reduced motivation
Unlike ADHD, depressive symptoms are often episodic, not lifelong.
How Clinicians Differentiate These Conditions
A proper diagnosis looks at pattern, timeline, and context.
Clinicians evaluate:
When symptoms began
Whether symptoms are constant or episodic
Which areas of life are affected
How symptoms respond to stress
Childhood history
This process is called differential diagnosis.
