Changes as You AgeResearchers are learning more about the ways symptoms can emerge, disappear and evolve.Listen \u00b7 7:57 min Share full articleCredit...Cristina SpanoBy Dana G. SmithSept. 10, 2026Leer en espa\u00f1olElizabeth\u2019s two sons, ages 8 and 10, have both been diagnosed with attention deficit hyperactivity disorder. So have Elizabeth, 37, and her husband, 41.To manage it all, Elizabeth and her husband have implemented an elaborate system of medications and to-do lists. There are white boards all over their Southern California home to help with task management and communication.\u201cI joke that our house is half house, half classroom, half occupational therapist office,\u201d Elizabeth said. (She asked to use only her middle name when discussing her family\u2019s medical conditions.)Elizabeth was diagnosed with A.D.H.D. two years ago, after recognizing some of her sons\u2019 symptoms in her current \u2014 and younger \u2014 self. \u201cI didn\u2019t know that the reason that it took me five hours to do my homework every night wasn\u2019t because I wasn\u2019t smart or because I didn\u2019t try hard enough,\u201d she said. \u201cIt\u2019s because my brain was working against me.\u201dAdvertisementSKIP ADVERTISEMENTNow, with help from her systems and from medication, Elizabeth has learned to manage her symptoms and has advanced in her career as an environmental health and safety manager. \u201cI went from bouncing around between random jobs,\u201d she said, to being able to \u201cfocus well enough to have some direction.\u201dBut despite her own success, Elizabeth still worries about how her sons\u2019 A.D.H.D. will affect them as they get older. \u201cAs a parent, my job is to teach them how to be a human, how to function in today\u2019s world,\u201d she said. \u201cAnd they have a harder time than most because their brains don\u2019t work the way most people\u2019s brains work.\u201dBack-to-school season, with its executive functioning demands and deadlines, can make these types of parental worries even more stark.A.D.H.D. is a tricky condition to diagnose, study and track over a person\u2019s life. It can present very differently in different people, and there are a wide range of symptoms, which exist on a spectrum from mild to severe. A.D.H.D. also often overlaps with other mental health, developmental and behavioral disorders, including anxiety, autism and oppositional defiant disorder. (With rising rates in children and adults, some psychiatrists worry the condition is now being over diagnosed.)It\u2019s also not clear what percentage of children continue to have A.D.H.D. as adults. One frequently cited number is about 50 percent, with symptoms more likely to persist in adults who had more severe A.D.H.D. in childhood and more overlapping conditions.AdvertisementSKIP ADVERTISEMENTBut according to a 2021 longitudinal study that followed children with A.D.H.D. for 16 years, only about 10 percent experienced \u201csustained remission\u201d into young adulthood. Another 10 percent had A.D.H.D. for the entire time, and for the vast majority, symptoms waxed and waned. Notably, the study found that at any given time, roughly half the participants met the diagnosis for A.D.H.D., but which people fell into which camp kept changing.While much about A.D.H.D. is still up in the air, what has become clear is that it is not a static condition, and the types of symptoms people have, and how they affect their day-to-day lives, can evolve over time.How Symptoms ChangeThere are two main categories of A.D.H.D. symptoms: inattentive and hyperactive-impulsive. To be diagnosed with A.D.H.D., a child must meet six or more symptoms from one category or the other; people 17 and older need five or more. If someone meets the symptom requirements in both categories, they are diagnosed as having combined A.D.H.D.Inattentive symptoms include things like poor attention to detail, not finishing tasks, messiness and forgetfulness. Hyperactive and impulsive symptoms can look like frequent fidgeting, difficulty waiting one\u2019s turn and excessive talking.In general, when children are very young, hyperactive-impulsive symptoms tend to be more common. Michelle Martel, a professor of psychology at the University of Kentucky, said it is obvious when you\u2019re working with a preschooler with these symptoms because \u201cthey\u2019re getting into everything and running around the room.\u201dAdvertisementSKIP ADVERTISEMENTAs children age and start to have more responsibilities and expectations at school, inattentive symptoms become more prevalent, and ultimately more persistent. And in some children, hyperactive-impulsive symptoms start to decline. According to one large 2023 review, in children under 12 there is a roughly even breakdown between primarily inattentive, primarily hyperactive-impulsive and combined presentations. Between the ages of 12 and 18, the numbers start to shift, with more adolescents qualifying as inattentive and less than a quarter as hyperactive-impulsive.Very few adults have predominantly hyperactive-impulsive symptoms. One small study put the number at just 7 percent, while roughly one-third of adults had the inattentive subtype and the majority had a combination of symptoms.Hyperactive-impulsive symptoms also present differently in adults than in children, manifesting more as an inner, mental restlessness rather than an outward, physical restlessness, said Dr. Deepti Anbarasan, a clinical associate professor of psychiatry at the N.Y.U. Grossman School of Medicine. For example, adults \u201cmay always feel a need to be busy, like they might need to exercise daily or otherwise they don\u2019t feel so good,\u201d she said.Adults with inattentive symptoms may have trouble with life logistics and with completing chores that don\u2019t have a deadline, or they might lose track of conversations during meetings or with their spouse, Dr. Anbarasan said.Why Symptoms ChangeThere is mounting evidence that people\u2019s environments can influence their symptoms. Having problems at home, like parents going through a divorce, may contribute to symptom severity in children and adolescents, said James Swanson, a professor of pediatrics at the University of California, Irvine.AdvertisementSKIP ADVERTISEMENTChildren may also struggle more with inattention in a \u201cstructured school setting where they\u2019re having to do things they don\u2019t like,\u201d Dr. Martel said. A person\u2019s symptoms may improve in adulthood when they find a job that better suits their temperament and personality, she added.Another reason A.D.H.D. can change with age is that many people eventually find ways to manage their condition so it\u2019s less disruptive. In general, the experts said, people with predominantly hyperactive-impulsive symptoms are more likely to be treated with behavioral interventions, while those with inattentive symptoms tend to respond better to medication. But for many people, especially those with combined A.D.H.D., a hybrid approach works best.Finally, neuroimaging research suggests that some of the changes people experience with age may be partially attributed to brain development. One recent study found that children whose symptoms improved over the course of two years showed a different pattern of brain development than those whose symptoms persisted or got worse.\u201cSome children just grow out of it,\u201d Dr. Swanson said. \u201cYou start with a group and you follow them over time, the symptoms decrease with age. That\u2019s just an age-related effect. I call it maturation.\u201dFrom the commentsDana SmithBrain health and longevity reporterIn reporting this story, I was fascinated to learn that symptoms tend to change as people get older. If you or someone you know has ADHD, does this ring true?AdvertisementSKIP ADVERTISEMENT",
