When most people think of Attention-Deficit/Hyperactivity Disorder (ADHD), they picture energetic children who can’t sit still in class. But ADHD is not just a childhood condition — it often continues into adulthood, sometimes undiagnosed for decades.
At Forbs Behavioral Health Services, LLC, serving Maryland and Washington, D.C., we work with adults who have spent years struggling with time management, focus, and organization without realizing these challenges were rooted in ADHD. Recognizing the signs in adulthood is crucial, because untreated ADHD can impact careers, relationships, self-esteem, and mental health.
In this guide, we’ll break down:
What ADHD looks like in adults
How symptoms differ from childhood presentations
The subtle and not-so-subtle signs to watch for
The impact of untreated ADHD

Why Adult ADHD Often Goes Undiagnosed
There are several reasons ADHD can fly under the radar for years:
1. Symptom Masking
Many adults develop coping mechanisms — like overworking, excessive list-making, or avoiding certain tasks altogether — that hide the underlying issue.
2. Stereotypes and Misconceptions
Because ADHD is associated with hyperactive children, inattentive or less visible symptoms in adults are often overlooked.
3. Overlap with Other Conditions
Symptoms such as forgetfulness, low motivation, and disorganization can mimic depression, anxiety, or stress.
4. Life Stage Changes
Increased responsibilities (career, family, financial management) can overwhelm coping strategies, making symptoms more noticeable later in life.
Core Symptoms of Adult ADHD
ADHD symptoms fall into three primary categories: inattention, hyperactivity, and impulsivity. Adults may experience one or a combination of these patterns.
Inattention
Adults with ADHD may:
Struggle to stay focused on work or conversations
Make careless mistakes due to missed details
Find it hard to follow through on tasks, even with good intentions
Frequently lose track of important items (keys, phone, documents)
Avoid or procrastinate on tasks requiring sustained mental effort
Hyperactivity
While physical hyperactivity often decreases with age, adults may still experience:
Inner restlessness or feeling “on edge”
Difficulty relaxing or sitting still for extended periods
Tendency to take on too many activities at once
Impulsivity
Impulsivity in adults can manifest as:
Interrupting others in conversation
Making quick decisions without considering consequences
Struggling with emotional regulation, leading to outbursts or sudden mood changes
Overspending or making unplanned purchases
Subtle Signs You Might Miss
Not all symptoms are obvious. Some adults experience:
Time blindness: Chronic difficulty estimating how long tasks will take
Hyperfocus: Becoming so absorbed in an activity that you lose track of time and neglect other priorities
Chronic disorganization: Even with effort, living or working spaces remain cluttered
Frequent job changes: Not due to lack of skill, but boredom or frustration with routine tasks
The Impact of Untreated Adult ADHD
When ADHD goes unrecognized, it can affect:
Careers
Missed deadlines and disorganization can stall promotions
Difficulty following workplace protocols can create tension with supervisor
Relationships
Forgotten commitments may lead to frustration from partners or friends
Impulsivity can result in hurtful comments or conflicts
Mental Health
Higher risk of anxiety and depression
Low self-esteem from years of feeling “lazy” or “undisciplined”
ADHD is not a character flaw — it’s a neurodevelopmental condition that responds well to targeted support.
How Adult ADHD Is Diagnosed
A comprehensive evaluation includes:
Clinical interviews to discuss history and current symptoms
Standardized ADHD rating scales
Input from family, partners, or close friends (with consent)
Screening for co-occurring conditions such as anxiety or depression
Strategies for Managing Adult ADHD
1. Externalize Organization
Use planners, apps, and reminders to track tasks
Color-code calendars for different areas of life
2. Break Tasks Into Smaller Steps
Avoid overwhelm by focusing on one piece of a larger task at a time
3. Create Routines
Consistent daily habits reduce decision fatigue
4. Manage Distractions
Limit phone notifications
Work in quiet spaces or use background noise for focus
5. Practice Self-Compassion
Recognize that ADHD is not laziness — it’s a brain difference that requires specific tools
