"Adult onset attention deficit disorder" is not a recognized medical or diagnostic term. In the context of attention deficit hyperactivity disorder (ADHD), there is no clear distinction between ADHD that begins in childhood and ADHD that starts in adulthood. The diagnostic criteria for ADHD apply to individuals of all ages.
ADHD is a neurodevelopmental disorder that typically presents in childhood, and symptoms often persist into adolescence and adulthood. However, it is not uncommon for some individuals to receive a formal diagnosis of ADHD later in life, during adulthood.
In some cases, individuals with ADHD may have experienced milder symptoms during childhood, which might not have been severe enough to warrant a diagnosis at that time. As they grow older and face increased responsibilities and demands in adulthood, their ADHD symptoms may become more apparent and impact their daily functioning.
It's important to note that when diagnosing ADHD in adults, healthcare professionals take into consideration the individual's developmental history and symptoms. They will assess whether the symptoms have been present since childhood or if they have emerged more recently in adulthood. Other medical and psychological conditions that can mimic or co-occur with ADHD will also be considered during the evaluation.
ADHD in adults may manifest differently than in children. While hyperactivity may decrease with age, problems with attention, organization, time management, and impulsivity can persist or become more evident in adult life. Adults with ADHD may struggle with work performance, educational pursuits, relationships, and other aspects of daily living.
If you suspect you may have ADHD as an adult or have concerns about your attention and executive functioning, it is essential to seek evaluation and diagnosis from a qualified healthcare professional, such as a psychiatrist or psychologist with experience in adult ADHD assessment. A thorough evaluation can help determine whether ADHD or another condition may be contributing to the symptoms, and appropriate treatment and support can be provided accordingly.
