ADD vs. ADHD in Adults: What's the Difference?
September 2025 · 7 min read · Medically reviewed by Dr. Jose Diaz, MD, Medical Director · Reviewed and updated September 29, 2026
ADD is an older name for attention-deficit disorder; ADHD, or attention-deficit/hyperactivity disorder, is the current term. You can have ADHD with mainly inattentive symptoms and little obvious hyperactivity. Clinicians describe three presentations: predominantly inattentive, predominantly hyperactive-impulsive and combined. Your symptom pattern and its effect on daily life guide the assessment.
At Padgett Medical Center in Tampa, the new patient ADHD visit is $169 when you book online with a card on file, 35% off the regular $260. Nothing is charged when you book. See adult ADHD care and pricing.
Why do you still hear the term ADD?
ADD remains familiar because people still use older wording in conversation and when describing past diagnoses. The current diagnostic term is ADHD, but hearing ADD does not tell you the full details of someone's assessment.
MedlinePlus explains that ADHD used to be called ADD. If you use ADD to mean trouble paying attention without much visible hyperactivity, say that plainly to your provider. Do not assume the shorthand gives every detail of your current symptoms.
Older records can contain useful history even when their wording differs from today's terminology. Keep the original record intact and ask the provider to interpret it alongside your present concerns. You do not need to rewrite an old diagnosis yourself.
For example, ask how an older label relates to the difficulties you have now. That gives you a more useful conversation than trying to settle the diagnosis from a word on a form.
What are the three ADHD presentations?
The three ADHD presentations are predominantly inattentive, predominantly hyperactive-impulsive and combined. A presentation is the pattern of symptoms a clinician identifies; it is not a separate illness or a complete description of you.
Predominantly inattentive presentation centers on difficulties with attention, organization and follow-through. You might lose track of instructions or leave tasks unfinished. A person with this presentation does not meet the full hyperactive-impulsive symptom criteria, though that does not mean every such symptom must be absent.
Predominantly hyperactive-impulsive presentation centers on restlessness, difficulty waiting and acting or speaking before thinking. In adults, the restless feeling can be less visible than the constant movement people associate with children. The full inattentive symptom criteria are not met for this presentation.
Combined presentation means both symptom groups meet the diagnostic criteria. The American Psychiatric Association describes the two groups and their thresholds. Your provider considers the full criteria, not just whether one example sounds familiar.
Why is hyperactivity in the name if you do not feel hyperactive?
The ADHD name includes hyperactivity because it covers the whole condition, including presentations where inattention is the main concern. You do not need to meet the hyperactive-impulsive symptom threshold to have predominantly inattentive ADHD.
Think of the name as an umbrella rather than a requirement to experience every possible sign. CDC describes the three presentations separately. The word hyperactivity should not stop you from discussing attention problems that are persistent and disruptive.
At the same time, absence of obvious hyperactivity does not prove inattentive ADHD. A provider still needs to assess your history, daily impact and possible alternative explanations.
When describing concerns, replace 'I cannot have ADHD because I sit still' with the details of what is difficult. Explain whether you miss instructions, lose essentials or struggle to finish responsibilities. Those details give the provider information that the condition's name cannot supply.
Does inattentive ADHD mean the condition is mild?
Inattentive describes the symptom pattern, not how mild or severe the condition is. Presentation and severity answer different questions.
MedlinePlus distinguishes the presentation from a severity assessment. A quiet person can still have meaningful daily difficulties. Being less disruptive to other people is not the same as having less difficulty with your own responsibilities.
When you prepare to discuss severity, describe the consequences you experience. Are important tasks unfinished? Do repeated missed details create problems? How much do these difficulties affect your relationships or ability to manage daily responsibilities?
You do not need to compare yourself with someone who has a different presentation. Their visible behavior cannot measure your needs. Explain your own experience, including what you manage successfully and where the problems remain.

Can your ADHD presentation change over time?
Your ADHD presentation can change as the pattern of symptoms changes. That is different from switching between two separate conditions called ADD and ADHD.
CDC notes that presentations may change over time. If a past evaluation described one pattern, tell your provider what is different now. Do not erase the earlier history or assume the old description explains everything forever.
For example, you might remember more visible restlessness when younger but now be most concerned about unfinished responsibilities. Describe the change without assigning a new presentation to yourself. Your provider decides how your current symptoms fit the criteria.
A useful comparison includes time periods and settings. What was difficult at school, and what is difficult at home now? What responsibilities or routines changed? You can also identify what stayed the same. The goal is an accurate account of your experience, not a search for the label you prefer.
Does the ADD label tell you which treatment you need?
An ADD label alone cannot tell you which medication or other treatment you need. Treatment decisions depend on your current difficulties, health history and how you respond to care.
The American Psychiatric Association describes medication, psychotherapy and practical strategies as adult treatment approaches. If medication is considered, NIMH advises an individualized plan with a provider. A presentation name does not choose a drug or dose for you.
For the treatment conversation, identify the responsibilities you would like to manage more reliably. Completing household paperwork and following a conversation are more concrete goals than 'fixing my ADD.' Ask how a proposed plan will address those concerns and how progress will be reviewed.
Read adult ADHD medication: stimulants vs. non-stimulants for the class comparison. The examples there explain options; they do not predict which one your provider will recommend.
How does Padgett approach an older ADD diagnosis?
Padgett Medical Center reviews your current symptoms and history rather than choosing treatment from an older label alone. The evaluation covers how long symptoms have been present, including childhood, how they affect work and home, health history, current medications and prior records.
Your new patient visit is 30 minutes, always in person at the Tampa clinic, with Morgan Colee, PA. The clinic is at 6904 W. Linebaugh Ave, Tampa, FL 33625. The regular visit is $260, or $169 when booked online with a card on file.
If treatment is appropriate, it may include stimulant or non-stimulant medication and non-medication strategies. No prescription is promised in advance. Medication is filled at your own pharmacy and is separate from the visit fee.
The adult ADHD service page explains care and booking details. You can use the terminology you know when raising your concerns. To discuss your current needs and older records with a provider, book a Tampa ADHD visit.

Frequently asked questions
Is inattentive ADHD automatically less severe than combined ADHD?
Inattentive ADHD is not automatically less severe than combined ADHD. Presentation describes which symptom groups meet the criteria, while severity concerns the symptoms and their effect on functioning. Your provider assesses your own difficulties rather than judging the impact from how noticeable your behavior is or from someone else's presentation. Source: MedlinePlus.
Can your ADHD presentation change as you get older?
Your ADHD presentation can change as your symptoms change over time. That does not mean an older diagnosis was necessarily wrong or that you have moved between separate ADD and ADHD illnesses. Describe what changed, when you noticed it and how it affects daily responsibilities so your provider can assess the current pattern. Source: CDC.
Does being quiet rule out ADHD?
Being quiet does not rule out ADHD. Predominantly inattentive ADHD can involve attention and organization difficulties without meeting the hyperactive-impulsive symptom threshold. Quiet behavior also does not confirm the diagnosis. Your provider still considers symptom duration, childhood history, more than one setting and functional impact, along with other possible explanations. Source: APA.
Does the wording on an old record determine your current treatment?
The wording on an old record does not determine your current treatment by itself. It supplies history for a provider to consider alongside your present symptoms and health. Keep the record as written, explain what you experience now and ask how the proposed plan addresses your current needs and treatment goals. Source: APA.
