Attention-deficit/hyperactivity disorder, ADHD, is a neurodevelopmental condition that affects attention regulation, impulse control and activity levels. It is present from childhood, even when it is not recognised or diagnosed until adulthood. Many adults who are diagnosed later in life describe having spent years attributing their difficulties to personality or lack of discipline, rather than to an underlying, diagnosable condition.
Common signs in adulthood
ADHD presents differently across people and across the lifespan. In adults, common patterns include difficulty sustaining attention on tasks that are not intrinsically interesting, disorganisation and missed deadlines, losing or misplacing items regularly, restlessness or an internal sense of being "on the go," interrupting others or struggling to wait your turn, and difficulty regulating emotional responses. Hyperactivity often looks less like visible fidgeting and more like racing thoughts or a persistent feeling of restlessness.
How a diagnosis is reached
A formal diagnosis is made by a licensed clinician, typically a psychiatrist or clinical psychologist, following a structured clinical interview. This usually draws on your developmental history, ideally including evidence that symptoms were present in childhood, standardised rating scales such as the DIVA-5 or ASRS, and an assessment of how significant your symptoms are across more than one area of life, such as work, relationships and daily functioning. Diagnostic criteria in most of the countries Eldava Health operates in follow DSM-5-TR or ICD-11.
What treatment can involve
Treatment plans are individual and are set by your prescribing clinician, not by any online tool. They can include stimulant or non-stimulant medication, psychoeducation, coaching focused on executive function strategies, and workplace or study accommodations. Not everyone who is diagnosed chooses medication, and some manage well with structured coaching and environmental changes alone.
