What is ADHD? Understanding Attention Deficit Hyperactivity Disorder

ADHD is not just distraction

Everyone gets distracted occasionally. However, in ADHD, inattention is persistent, frequent, and causes significant functional impairment in a person's life. ADHD begins early in life, even if it is only noticed or diagnosed later. It is not a matter of "lack of effort" or "laziness" — it is a real neurobiological condition that affects brain functioning.

Main characteristics of ADHD

🔹 Inattention

🔹 Hyperactivity

🔹 Impulsivity

ADHD in children and adults

In childhood, ADHD often manifests as visible physical hyperactivity, difficulty following rules, and behavioral problems at school. In adulthood, symptoms may change: physical hyperactivity tends to decrease, giving way to internal restlessness, while attention and organization problems may become more evident, especially in professional contexts. Many adults only discover they have ADHD after years of struggling with difficulties they couldn't explain. This happens because childhood diagnosis may have been missed or because symptoms became more evident with adult life demands.

Are there different types of ADHD?

Yes. ADHD can present in three main forms, although all are classified under the same ADHD diagnosis: Important note: The term "ADD" is not a separate diagnosis, but a popular way to refer to the inattentive profile of ADHD.

Predominantly inattentive profile

Characterized mainly by attention and organization difficulties, with little or no visible physical hyperactivity. More common in adults and women.

Hyperactive/impulsive profile

Characterized mainly by hyperactivity and impulsivity, with fewer inattention symptoms. Less common in adults.

Is ADHD a disease?

ADHD is not a "disease" in the traditional sense, but rather a neurodevelopmental disorder. It is a neurological condition that affects brain functioning, especially in areas related to attention, impulse control, and executive functions. It is not something you "catch" or "cure" — it is a neurological characteristic with which a person is born.

Is there a cure for ADHD?

ADHD does not have a "cure" in the traditional sense, as it is not a disease that is completely eliminated. However, with proper treatment (which may include therapy, medication when indicated, and organization strategies), many people with ADHD can manage their symptoms very well and have a full and productive life. The goal of treatment is to improve quality of life and reduce the impact of symptoms.

Can adults develop ADHD?

No. ADHD is a neurodevelopmental disorder that begins in childhood. Adults do not "develop" ADHD, but may receive the diagnosis for the first time in adulthood. This happens because symptoms may have gone unnoticed in childhood, or because they became more evident with adult life demands (work, responsibilities, relationships).

Are ADHD and anxiety the same thing?

No. ADHD and anxiety are different conditions, although they can coexist and have overlapping symptoms. Anxiety can cause difficulty concentrating, but in ADHD, inattention is a primary symptom that exists independently of anxiety. A professional evaluation is important to differentiate between these conditions, as treatment may be different.

How is ADHD diagnosed?

ADHD diagnosis is made by a doctor (usually a psychiatrist or neurologist) or qualified psychologist through a complete clinical evaluation. This includes: detailed interview about symptom history since childhood, use of validated assessment scales, collection of information from family members or close people when possible, and exclusion of other conditions that may cause similar symptoms. The process may take several sessions and it is important to be honest and detailed during the evaluation.
