Quick Recap: Difference Between ADHD and ADD
- ADD is an outdated term; what used to be called ADD is now recognized as ADHD-Inattentive Presentation.
- Inattentive ADHD includes symptoms like forgetfulness, mental drifting, difficulty staying organized, and trouble sustaining focus — often without any hyperactivity.
- Many adults, especially women, go undiagnosed because these symptoms are internal, quiet, and frequently mistaken for stress or personality traits.
- Diagnosis requires a full psychiatric evaluation that reviews history, functional impact, and overlapping conditions.
Many people become curious about the difference between ADHD and ADD when their symptoms don’t match the image of “typical” ADHD. They’re not hyperactive, impulsive, or constantly moving—they’re forgetful, overwhelmed, mentally drained, or struggling to stay organized despite trying hard.
These experiences are valid clinical symptoms, and understanding them begins with clarifying the terminology that has confused patients for decades. For many adults, especially women, this clarity is the first step toward understanding long-standing patterns that were never identified in childhood.
If you relate to these symptoms and want professional guidance, Alpenglow Behavioral Health provides in-person ADHD evaluations and treatment with Dr. Spencer Augustin, a board-certified psychiatrist in Anchorage, Alaska, who specializes in diagnosing ADHD in adults, adolescents, and children.
Difference Between ADHD And ADD: What These Terms *Actually* Mean
When people ask what is the difference between ADD and ADHD, they’re usually trying to make sense of symptoms that don’t include noticeable hyperactivity. Historically, ADD was used to describe individuals who primarily struggled with inattention—difficulty focusing, forgetfulness, trouble completing tasks—but did not show impulsive or hyperactive behavior. Modern diagnostic standards now classify these symptoms under ADHD instead of using two separate terms.
So, are ADHD and ADD the same thing? Medically, yes. ADD no longer exists as a formal diagnosis, and what was once called ADD is now recognized as the inattentive presentation of ADHD. This shift helps clinicians apply consistent criteria, understand symptom patterns across age groups, and provide treatment that reflects how the condition actually impacts daily functioning.
Why People Still Use The Term ADD Today
The term remains popular for several reasons. Many adults were originally diagnosed with “ADD” before the terminology changed in 1987, so it’s still the language that feels natural to them. Others heard teachers or parents use the term throughout childhood, especially for quieter children who struggled with focus but weren’t disruptive. And for many adults, particularly women, the inattentive symptoms simply feel more aligned with the word “ADD” than with a term that includes “hyperactivity.”
Using the word isn’t “incorrect”—it’s simply rooted in older diagnostic language. In a psychiatric evaluation, the priority is to understand your symptoms and how they affect your daily life, not the vocabulary you use to describe them.
Why ADD Is No Longer Used As A Diagnosis

ADD was removed as an official diagnosis in 1987 when research confirmed that attention-related symptoms, whether inattentive or hyperactive, stem from the same underlying neurological condition. This led clinicians to adopt a single diagnosis—ADHD—with different presentations rather than using separate terms.
The shift also clarified how symptoms appear at different ages. Inattentive symptoms were frequently overlooked in girls and adults, and the previous system didn’t reflect how ADHD presents outside childhood. If you’ve wondered “how do I know if I have ADHD or ADD?”, the clearest answer comes from a comprehensive evaluation that examines how your symptoms developed and how they affect your daily life now.
ADHD vs ADD Symptoms: How Inattentive ADHD Shows Up In Everyday Life
ADHD-Inattentive Presentation is the modern diagnostic term that reflects what people used to call ADD. This presentation involves difficulties with focus, organization, time management, working memory, and sustaining mental effort. Because these symptoms are inward and quiet, they often go unnoticed, especially in high-achieving adults or children who learn to compensate through structure, masking, or perfectionism.
Clinical patterns may include:
- Difficulty sustaining attention on tasks that require mental effort
- Challenges with organizing materials, plans, or steps in a sequence
- Reduced working memory (forgetting information moments after receiving it)
- Losing track of time or drifting away from tasks unintentionally
- Starting tasks easily but struggling to maintain momentum
- Procrastinating on responsibilities that feel mentally demanding
Everyday-life patterns often look like:
- Zoning out during conversations, meetings, or lectures
- Rereading messages or instructions because the information didn’t “stick”
- Forgetting appointments, deadlines, or follow-through steps
- Struggling to initiate tasks even when they feel important
- Missing small details at work or at home despite wanting to be thorough
- Feeling mentally overloaded when switching between tasks
- Difficulty managing routines, priorities, or multitasking without burnout
Gender differences matter, too.
In many women, inattentive ADHD can blend with emotional sensitivity, constant overthinking, or people-pleasing—patterns often mistaken for anxiety or stress. Because of this, many women are diagnosed later in life, even when symptoms have been present since childhood.
How ADHD Is Diagnosed: What To Expect During A Psychiatric Evaluation
A proper ADHD diagnosis requires more than a brief questionnaire. It involves a comprehensive evaluation that looks at developmental history, symptom patterns, functional impact, and similarities to other conditions. Many people begin this process when inattentive symptoms affect productivity, relationships, daily responsibilities, or self-esteem. A thorough psychiatric evaluation provides clarity and helps determine the most accurate diagnosis and treatment path.
During an ADHD evaluation at Alpenglow Behavioral Health, you meet with a board-certified psychiatrist who reviews your symptom patterns across childhood and adulthood. The assessment explores attention challenges, executive functioning, emotional regulation, sleep, mood, and medical factors that may overlap with or mimic ADHD. For adolescents and children, collateral information from parents or teachers helps form a complete understanding.

Treatment Options For Inattentive ADHD
Treatment for inattentive ADHD is designed to support focus, memory, organization, and emotional regulation. Medication can be a highly effective tool for many individuals because it helps balance neurotransmitter activity (the chemical messengers in the brain that regulate attention, motivation, and impulse control) and improves the brain’s ability to manage attention and task initiation. Both stimulant and non-stimulant options may be considered depending on your symptoms, lifestyle, and medical history.
Non-medication approaches also play an important role. Many people benefit from:
- cognitive-behavioral strategies
- executive functioning coaching
- structured routines
- time-management systems
- sleep and lifestyle adjustments
These strategies work best when they are personalized rather than one-size-fits-all. That’s why a thoughtful, individualized treatment plan can make a meaningful difference.
At Alpenglow Behavioral Health, treatment is collaborative and patient-centered. Dr. Spencer Augustin provides education, guidance, and ongoing medication management while helping you take an active role in shaping your care.

ADD is an outdated term. Today, all presentations fall under the diagnosis of ADHD, which includes inattentive, hyperactive-impulsive, and combined types.
What does ADD mean?
It’s an informal way some people describe ADHD without hyperactivity. Clinically, this is called ADHD-Inattentive Presentation.
Is there a difference between ADD and ADHD in adults?
The terminology is the same—ADHD. The difference lies in how symptoms show up. Adults with inattentive ADHD often struggle with organization, memory, and sustained focus rather than hyperactivity.
What are common symptoms of ADD?
Symptoms associated with the old term ADD include forgetfulness, distractibility, losing track of tasks, trouble finishing projects, and difficulty concentrating for long periods.
How can I tell if I have ADHD-Inattentive Presentation?
The most reliable way is through a psychiatric evaluation that reviews childhood history, daily functioning, and symptom patterns across different settings.
Can adults be diagnosed even if they were never hyperactive as children?
Yes. Many individuals with inattentive ADHD were quiet, internal processors as kids, which often led to missed or delayed diagnosis.
