Adult ADHD assessment
ADHD is not only a childhood condition. Many adults live with ADHD that continues to affect daily life, often without a clear explanation for struggles they have carried for years. An assessment can clarify whether ADHD is present and what supports may help.

Can adults have ADHD?
Yes. Although ADHD is often thought of as a childhood condition, it is now well understood that it can continue into adulthood. Many individuals diagnosed in childhood continue to experience symptoms that affect their daily functioning.
ADHD may look different in adults than in children. While overt hyperactivity often becomes less noticeable with age, difficulties with attention, organization, impulse control and executive functioning frequently remain. Some adults describe feeling mentally restless rather than physically hyperactive.
ADHD can affect many areas of adult life, including work, education, relationships and overall well-being. Difficulties with planning, prioritizing and completing tasks can lead to missed deadlines, increased stress and frustration.
ADHD also commonly occurs alongside other concerns, such as anxiety, depression or low self-esteem. A comprehensive assessment helps clarify whether ADHD is present and identify factors that may be contributing to current challenges.
