Adult ADHD Testing, Diagnosis & Treatment in Wilmington, Delaware
If you live or work in Wilmington or elsewhere in New Castle County and have been wondering whether ADHD may be contributing to problems with focus, procrastination, organization, time management, working memory, task initiation, or follow-through, ADHD Philadelphia provides adult-focused ADHD evaluation and treatment throughout Delaware.
Many adults reach adulthood without realizing that long-standing difficulties with attention or executive functioning may be related to ADHD.
Some performed well in school. Others built successful careers, developed elaborate organizational systems, or relied on deadline pressure and long work hours to compensate.
ADHD Philadelphia provides adult ADHD evaluation, testing, diagnosis, treatment planning, and medication management for adults ages 18–64.
Initial appointments begin through secure telehealth for adults who are physically located in Delaware at the time of the appointment.
In-person appointments may be scheduled later at our Milford, Delaware office when clinically appropriate.

Long-term projects
Competing priorities
Everyday routines
The problem is often not understanding what needs to be done.

Wilmington Riverfront
North Wilmington

Two Adult ADHD Evaluation Options for Wilmington Adults
Adults seek ADHD evaluations for different reasons.
Some want diagnostic clarification and plan to continue treatment with ADHD Philadelphia.
Others want a comprehensive diagnostic evaluation but expect their ongoing treatment to occur elsewhere.
ADHD Philadelphia therefore offers two evaluation pathways.
Pathway 1 — ADHD Evaluation + Ongoing Care
$300 Total Initial Evaluation
This pathway is intended for adults who want an ADHD evaluation and plan to establish ongoing ADHD treatment with ADHD Philadelphia when continued care is clinically appropriate.
Step 1 — Initial ADHD Consultation: $150
The consultation may review:
Current ADHD symptoms
Childhood and developmental history
Functional impairment
Work and academic functioning
Executive-function concerns
Organization
Time management
Task initiation
Working memory
Follow-through
Sleep
Medical history
Psychiatric history
Current medications
Previous treatment
Substance-use considerations
Possible alternative explanations for symptoms
Possible co-occurring conditions
The purpose is not simply to determine whether you recognize ADHD symptoms.
The goal is to understand the broader developmental and clinical pattern.
Step 2 — ADHD Testing & Results Appointment: $150
Testing, standardized questionnaires, clinical findings, and other relevant information are integrated with the broader diagnostic evaluation.
Your findings are reviewed with you.
When ADHD is diagnosed, individualized treatment recommendations and possible next steps are discussed.
Total Initial Evaluation: $300
$150 Initial ADHD Consultation
+
$150 ADHD Testing & Results Appointment
This pathway is intended for adults establishing ongoing ADHD treatment with ADHD Philadelphia.
Ongoing ADHD Care
Ongoing treatment and medication-management appointments are:
$150 per appointment
START ADHD EVALUATION + ONGOING CARE
Pathway 2 — ADHD Testing & Evaluation Only
$500 Comprehensive Standalone Diagnostic Evaluation
This pathway is designed for adults who want a comprehensive ADHD diagnostic evaluation but do not plan to establish ongoing ADHD treatment with ADHD Philadelphia at the time of the evaluation.
It may be appropriate when your primary goal is:
Diagnostic clarification
Comprehensive adult ADHD evaluation
ADHD testing
Diagnostic documentation
Understanding long-standing attention or executive-function difficulties
Having evaluation findings available as part of care provided elsewhere
Depending on the individual evaluation, the process may include:
Detailed clinical diagnostic interview
Current ADHD symptom assessment
Childhood and developmental history
Functional impairment assessment
Work and academic functioning
Executive-function assessment
Medical history
Psychiatric history
Sleep
Medication review
Substance-use considerations
Standardized ADHD questionnaires
ADHD testing
Differential diagnosis
Relevant records when required
Collateral information when clinically appropriate
Additional information necessary to reach an appropriate diagnostic conclusion
Total Standalone Evaluation: $500
This is a comprehensive diagnostic service rather than an ongoing-treatment pathway.
Diagnostic Documentation
Diagnostic documentation is generally completed within 7 days after all required appointments, testing, questionnaires, records, and requested information have been completed and received.
The seven-day period does not necessarily begin after the first appointment.
START ADHD TESTING & EVALUATION ONLY
Which ADHD Evaluation Should I Choose?
Choose ADHD Evaluation + Ongoing Care — $300 if:
You want an evaluation and intend to establish ongoing ADHD treatment with ADHD Philadelphia if continued care is clinically appropriate.
Initial evaluation: $300
Ongoing appointments: $150 each
Choose ADHD Testing & Evaluation Only — $500 if:
Your primary goal is comprehensive diagnostic clarification or documentation and you do not plan to establish ongoing treatment with ADHD Philadelphia at the time of the evaluation.
For a complete explanation of both pathways, follow the ADHD Philadelphia Patient Journey.
When Should a Wilmington Adult Consider an ADHD Evaluation?
An evaluation may be worth considering when there is a persistent pattern involving:
Difficulty staying focused
Chronic procrastination
Difficulty beginning important tasks
Frequently unfinished projects
Poor time awareness
Forgetting appointments or responsibilities
Losing track of instructions
Difficulty following through
Disorganization
Missing deadlines
Difficulty prioritizing
Mental restlessness
Impulsive decisions
Frequently misplacing important items
Difficulty transitioning between tasks
Feeling overwhelmed by competing responsibilities
Relying on deadline pressure to become productive
These difficulties can occur for many reasons.
ADHD is one possibility—not the only possibility.

Adult ADHD Does Not Always Look Like Hyperactivity
Adults with ADHD do not all appear physically hyperactive.
ADHD may instead appear as:
Mental restlessness
Chronic procrastination
Difficulty finishing routine tasks
Frequently switching activities
Forgetfulness
Time-management problems
Difficulty maintaining routines
Inconsistent productivity
Trouble organizing information
Feeling chronically behind
Hyperfocus on interesting tasks
Difficulty beginning less stimulating work
Needing urgency to become productive
Some adults primarily experience inattentive symptoms.
Others experience combinations of inattention, hyperactivity, and impulsivity.
The evaluation considers the overall developmental pattern rather than relying on stereotypes.
Successful Professionals in Wilmington Can Still Have ADHD
Professional success does not automatically rule out ADHD.
Wilmington and New Castle County include adults working in demanding fields such as:
Healthcare
Finance
Banking
Law
Business leadership
Technology
Government
Education
Consulting
Entrepreneurship
Corporate management
Professional services
A successful adult may still rely heavily on:
Long work hours
Deadline pressure
Anxiety
Repeated checking
Multiple calendars
Extensive reminders
Administrative support
Working late at night
Weekend catch-up
Perfectionism
A useful diagnostic question is not simply:
“Are you successful?”
It is also:
“What does maintaining that success require from you?”

Adult ADHD Care That Recognizes the Whole Person
Wilmington and New Castle County adults come from diverse racial, cultural, professional, gender, and LGBTQ+ communities. ADHD evaluation should allow relevant life experiences to be discussed without assuming that identity itself explains attention or executive-function difficulties.

Wilmington and New Castle County adults come from diverse racial, cultural, gender, professional, and LGBTQ+ communities.

ADHD Testing Is Only One Part of Diagnosis
There is no single computerized test, questionnaire, online quiz, blood test, or brain scan that independently diagnoses adult ADHD.
Testing may provide useful information.
Standardized rating scales may also provide useful information.
Neither replaces the broader clinical evaluation.
Diagnosis may consider:
Current symptoms
Childhood and developmental history
Functional impairment
Symptoms across relevant areas of life
Work and academic functioning
Medical history
Psychiatric history
Sleep
Medication effects
Substance-use considerations
Possible alternative diagnoses
Possible co-occurring conditions
Standardized questionnaires
Testing information when clinically appropriate
Current NIMH guidance similarly describes adult ADHD assessment as drawing on childhood history, clinical interviews, rating scales, medical and mental-health history, and sometimes cognitive testing.

Why Childhood History Matters
ADHD is a neurodevelopmental condition.
You do not need to have received an ADHD diagnosis as a child.
Many adults were never evaluated.
Relevant childhood patterns may include:
Daydreaming
Losing homework
Forgetting assignments
Chronic procrastination
Disorganization
Needing substantial external structure
Restlessness
Excessive talking
Inconsistent academic performance
Performing much better in highly interesting subjects
Being described as intelligent but inconsistent
CDC and NIMH both note that ADHD symptoms begin in childhood even when the formal diagnosis is first made in adulthood.
Conditions That Can Look Like ADHD
Problems with attention and executive function may occur with:
Anxiety
Depression
Bipolar disorder
Trauma-related conditions
Sleep problems
Chronic stress
Burnout
Substance use
Medication effects
Medical conditions
Other psychiatric conditions
Other neurodevelopmental conditions
Sometimes ADHD is the best explanation.
Sometimes another condition better explains the symptoms.
Sometimes ADHD and another condition occur together.
This is why differential diagnosis matters.

Executive Function and Adult ADHD
Many adults seeking evaluation describe problems such as:
“I know what I need to do, but I cannot get started.”
“I keep underestimating how long everything takes.”
“I make a plan but cannot follow it consistently.”
“I forget what I was doing after an interruption.”
“I only become productive when the deadline becomes urgent.”
These concerns may involve executive functions such as:
Working memory
Task initiation
Planning
Prioritization
Organization
Time management
Sustained attention
Response inhibition
Cognitive flexibility
Goal-directed persistence
Self-monitoring
Emotional regulation
