ADHD (Attention-deficit/hyperactivity disorder) can present in different subtypes, which are based on the predominant symptoms that an individual experiences. The three main subtypes are:
ADHD predominantly inattentive presentation (previously known as ADHD inattentive type): Individuals with this subtype primarily exhibit symptoms of inattention, such as difficulty sustaining attention, being easily distracted, forgetfulness, and struggling with organization and time management.
ADHD predominantly hyperactive-impulsive presentation (previously known as ADHD hyperactive-impulsive type): Individuals with this subtype predominantly display symptoms of hyperactivity and impulsivity. Hyperactivity symptoms include excessive fidgeting, restlessness, difficulty staying seated, and an overall sense of being "on the go." Impulsivity symptoms involve acting without thinking, interrupting others, and having difficulty waiting for their turn.
ADHD combined presentation: This is the most common subtype, where individuals experience both inattentive and hyperactive-impulsive symptoms.
It is possible for a person to exhibit symptoms that don't fit neatly into one subtype and may have features of more than one subtype. In your case, it is conceivable that someone could meet the criteria for ADHD predominantly inattentive presentation but also display some hyperactivity-like behaviors. These behaviors might not be severe enough to qualify for the hyperactive-impulsive subtype, but they could still be noticeable.
It's essential to understand that each person's experience with ADHD can be unique, and the symptoms can vary in intensity and presentation. Additionally, the diagnostic criteria for mental health conditions might be updated over time, so it's always best to consult a qualified healthcare professional for an accurate evaluation if someone is experiencing challenges related to attention and hyperactivity. They can provide a proper assessment and create a tailored treatment plan based on the individual's specific needs.
