Attention Deficit Disorder (ADD) and Attention Deficit Hyperactivity Disorder (ADHD) are related but slightly different conditions. Historically, they were considered two distinct diagnoses, with ADD referring to individuals who primarily struggled with attention difficulties without significant hyperactivity, and ADHD referring to those who had both attention difficulties and hyperactive-impulsive symptoms.
However, in more recent diagnostic criteria, such as the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th edition), the term ADHD is now used to encompass both presentations:
ADHD Predominantly Inattentive Presentation: This is similar to the older concept of ADD. Individuals with this type of ADHD have difficulties sustaining attention, staying organized, and may be forgetful or easily distracted. They do not display significant hyperactive or impulsive behaviors.
ADHD Predominantly Hyperactive-Impulsive Presentation: This type involves prominent hyperactive and impulsive behaviors but without significant attention difficulties.
ADHD Combined Presentation: This is the most common type, where individuals experience both inattention and hyperactivity-impulsivity.
Because of these changes in diagnostic terminology, you might find more references to ADHD than ADD in contemporary research and literature. Additionally, when people use the term "ADD" colloquially, they often refer to the inattentive presentation of ADHD.
It's important to note that the diagnosis of ADHD is made based on a thorough evaluation by a qualified healthcare professional, and it's crucial to consider individual differences in symptoms and their impact on daily life. If you suspect you or someone you know might have ADHD or any other mental health condition, it's essential to seek professional evaluation and guidance for an accurate diagnosis and appropriate management.
