What is ADHD and how is it diagnosed? 

ADHD diagnosis is the process of identifying Attention Deficit Hyperactivity Disorder (ADHD), a condition marked by persistent patterns of inattention, hyperactivity, and impulsivity. It affects children and adults, influencing their ability to focus, regulate impulses, and manage behaviour in various environments, such as school or work. The ADHD diagnosis include a thorough clinical evaluation, including gathering medical history, behavioural observations, and symptom reports. 

Key Symptoms of ADHD 

To diagnose ADHD, healthcare professionals look for specific symptoms. These typically fall under three categories: inattention, hyperactivity, and impulsivity. 

Inattention 

This refers to difficulties in focusing, following instructions, and staying on task. Children or adults with ADHD may often lose track of details or forget important assignments. They might also appear disorganised or struggle to keep up with schoolwork or professional responsibilities. 

Hyperactivity 

Hyperactivity involves excessive movement, talking, or restlessness, especially in situations requiring calmness. Individuals may find it difficult to sit still, leading to behaviours like fidgeting, tapping feet, or getting up frequently during meetings or classes. 

Impulsivity 

Impulsivity in ADHD often manifests as acting without thinking, leading to hasty decisions or interrupting others. People with ADHD might interrupt conversations, make snap decisions, or struggle with waiting their turn in group settings. 

Clinical Criteria for Diagnosis  

A comprehensive ADHD diagnosis involves using clinical criteria from the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition). This includes evaluating the intensity, duration, and impact of symptoms. Doctors use interviews, questionnaires, and behaviour assessments to ensure the diagnosis is accurate. 

In summary, ADHD diagnosis relies on identifying key symptoms and applying clinical criteria to ensure accurate identification. Early diagnosis is crucial for effective treatment and support. Understanding these symptoms and the diagnostic process can provide clarity for both individuals and healthcare professionals.
