Overview
ADHD is a neurodevelopmental condition that usually becomes apparent during childhood, often when difficulties with attention, behaviour or functioning are first identified. Symptoms may continue into adulthood and can include distractibility, problems sustaining concentration, disorganisation and difficulty managing tasks. However, similar difficulties can also arise from other mental health or psychological conditions.
When considering ADHD, evidence that symptoms were present during childhood is important. The absence of reported concerns from parents, carers or teachers, particularly alongside consistently good academic progress through secondary education, may make ADHD less likely. Conversely, persistent symptoms that cause significant impairment across several areas of everyday life, such as education, employment, relationships or home functioning, provide stronger support for an ADHD diagnosis.
