The terms ADD (Attention Deficit Disorder) and ADHD (Attention Deficit Hyperactivity Disorder) are frequently used interchangeably, but there is often confusion surrounding their differences and whether one can have both conditions. In reality, ADD is now considered an outdated term that has been subsumed under the broader diagnosis of ADHD, with distinct presentations that capture the range of symptoms individuals might experience. This article delves into the history of these terms, clarifies the current diagnostic criteria, explores the possibility of having combined symptoms, and discusses the implications for diagnosis and treatment.
Historical Context and Evolution of Terms
ADD: The Initial Concept
The term Attention Deficit Disorder (ADD) was first introduced in the Diagnostic and Statistical Manual of Mental Disorders (DSM-III) published by the American Psychiatric Association (APA) in 1980. ADD was characterized primarily by symptoms of inattention without the hyperactive and impulsive behaviors that are often associated with ADHD. This distinction was made to recognize that not all individuals with attention deficits displayed hyperactivity.
The Shift to ADHD
In 1987, the revised third edition of the DSM (DSM-III-R) reclassified ADD under the broader term Attention Deficit Hyperactivity Disorder (ADHD). This revision introduced three subtypes of ADHD: predominantly hyperactive-impulsive, predominantly inattentive, and combined presentation. The goal was to provide a more comprehensive understanding of the disorder by acknowledging the different ways in which symptoms could manifest.
DSM-IV and DSM-5 Refinements
The DSM-IV, published in 1994, retained the three subtypes of ADHD and further refined the diagnostic criteria. The most recent edition, DSM-5, published in 2013, continues to use the term ADHD with the same three presentations: predominantly inattentive, predominantly hyperactive-impulsive, and combined presentation. This framework reflects the current understanding that ADHD is a heterogeneous disorder with varying symptom profiles.
Understanding ADHD and Its Presentations
Predominantly Inattentive Presentation
Individuals with predominantly inattentive ADHD (formerly referred to as ADD) exhibit significant difficulties with attention and focus. Symptoms may include:
- Trouble sustaining attention in tasks or play activities
- Frequent careless mistakes in schoolwork or work
- Difficulty organizing tasks and activities
- Avoidance or reluctance to engage in tasks requiring sustained mental effort
- Often losing things necessary for tasks and activities
- Easily distracted by extraneous stimuli
- Forgetfulness in daily activities
Predominantly Hyperactive-Impulsive Presentation
Those with predominantly hyperactive-impulsive ADHD display symptoms of hyperactivity and impulsivity without significant attention deficits. Symptoms may include:
- Fidgeting or tapping hands and feet
- Inability to remain seated in situations where it is expected
- Running or climbing in inappropriate situations
- Inability to play or engage in leisure activities quietly
- Often “on the go” or acting as if “driven by a motor”
- Excessive talking
- Interrupting or intruding on others
Combined Presentation
The combined presentation is diagnosed when individuals meet the criteria for both inattentive and hyperactive-impulsive symptoms. This presentation is the most common form of ADHD and captures the full spectrum of the disorder.

Clarifying the Terminology
Given that ADD is now considered a subtype of ADHD rather than a separate condition, one cannot be diagnosed with both ADD and ADHD simultaneously. However, individuals can exhibit symptoms of both inattention and hyperactivity-impulsivity, which would fall under the combined presentation of ADHD.
Co-Occurrence of Symptoms
While the terminology might suggest a clear-cut distinction, the reality is that ADHD symptoms often overlap. Many individuals exhibit a mix of inattentive and hyperactive-impulsive behaviors. The presence of both sets of symptoms does not mean that one has two separate conditions, but rather that their ADHD diagnosis encompasses a broader range of symptoms.
Diagnostic Criteria and Evaluation
DSM-5 Criteria
The DSM-5 outlines specific criteria for diagnosing ADHD, including:
- Symptoms must be present for at least six months
- Symptoms must be inappropriate for the individual’s developmental level
- Several symptoms must be present before age 12
- Symptoms must be evident in two or more settings (e.g., school, home, work)
- Symptoms must interfere with or reduce the quality of social, academic, or occupational functioning
Comprehensive Evaluation
Diagnosing ADHD involves a comprehensive evaluation that includes:
- Clinical interviews with the individual and family members
- Behavioral assessments and rating scales
- Review of academic and medical history
- Observation of behavior in different settings
A thorough evaluation helps ensure an accurate diagnosis and informs the development of an effective treatment plan.
Implications for Treatment and Management
Individualized Treatment Plans
The presence of both inattentive and hyperactive-impulsive symptoms necessitates a tailored approach to treatment. Individualized treatment plans may include a combination of medication, behavioral therapy, and lifestyle interventions.
Medication
Medications commonly used to treat ADHD include stimulants (e.g., methylphenidate, amphetamines) and non-stimulants (e.g., atomoxetine, guanfacine). These medications can help manage symptoms by enhancing focus, reducing hyperactivity, and improving impulse control. The choice of medication and dosage is typically based on the individual’s specific symptoms and response to treatment.
Behavioral Therapy
Behavioral therapy, including cognitive-behavioral therapy (CBT), is an effective treatment for managing ADHD symptoms. Therapy can help individuals develop strategies for organizing tasks, managing time, improving focus, and regulating emotions. Family therapy and parent training programs can also provide support and teach effective ways to manage behavior.
Lifestyle Interventions
Lifestyle interventions play a crucial role in managing ADHD. Regular physical activity, a healthy diet, adequate sleep, and mindfulness practices can help reduce symptoms and improve overall well-being. Structured routines and organizational tools, such as planners and reminder systems, can assist in managing daily tasks and responsibilities.
The Role of Support Systems
Family Support
Family support is essential for individuals with ADHD. Understanding and patience from family members can create a supportive environment that fosters growth and development. Involvement in therapy and educational planning can help families develop effective strategies for managing ADHD symptoms.
Educational Support
Educational support, such as Individualized Education Plans (IEPs) and 504 Plans, can provide accommodations and modifications to help students with ADHD succeed academically. These plans may include extended time for tests, preferential seating, and additional support for organization and time management.
Workplace Accommodations
For adults with ADHD, workplace accommodations can help improve job performance and reduce stress. Accommodations might include flexible work hours, the option to work in a quiet space, and tools for organization and time management. Employers can play a significant role in supporting employees with ADHD by fostering an inclusive and understanding work environment.
Research and Advances in ADHD
Neurobiological Insights
Research into the neurobiological underpinnings of ADHD has provided valuable insights into the disorder. Studies have identified differences in brain structure and function, particularly in areas related to attention, executive function, and impulse control. These findings support the classification of ADHD as a neurodevelopmental disorder and highlight the importance of early intervention and ongoing support.
Genetic Factors
Genetic research has demonstrated that ADHD has a strong hereditary component. Multiple genes have been implicated in the development of ADHD, with each contributing a small effect. Understanding the genetic basis of ADHD can inform the development of targeted treatments and personalized interventions.
Longitudinal Studies
Longitudinal studies have provided insights into the developmental trajectory of ADHD. These studies have shown that while symptoms can change over time, ADHD often persists into adulthood. Understanding the long-term outcomes of ADHD can help inform treatment planning and support strategies across the lifespan.
Conclusion
The evolution of the terms ADD and ADHD reflects our growing understanding of attention deficit disorders. While ADD is now considered a subtype of ADHD, the recognition of different presentations of ADHD has enhanced our ability to diagnose and treat this complex condition. Individuals can exhibit a range of symptoms, including both inattention and hyperactivity-impulsivity, which are captured under the combined presentation of ADHD. A comprehensive approach to diagnosis and treatment, including medication, behavioral therapy, lifestyle interventions, and support systems, is essential for managing ADHD effectively. Ongoing research continues to deepen our understanding of ADHD and improve outcomes for individuals with this condition.
