To gauge the extent of stigma towards persons with ADHD, a European research team hired a company specialized in market and social research to conduct a poll of some five thousand randomly selected Germans. Just over a thousand completed the interview, representing a response rate of only one in five. The team acknowledged, "Although non-responder bias has to be considered to be important, ethical considerations prohibited the collection of any detailed information on non-respondents." The sample had slightly more women and elderly persons, and a higher average level of educational attainment relative to the German population as a whole. Sampling weights we reused to compensate for these discrepancies.
The poll relied on computer-assisted telephone interviews. Interviews began with prerecorded vignettes of either an a12-year-old child or a 35-year-old adult exhibiting core symptoms of ADHD (such as "careless mistakes in schoolwork," "does not follow through on instructions," easily distracted by extraneous stimuli, "loses things", "leaves his place in the classroom or when sitting at the dining table"). Half of those interviewed were presented with child vignettes and half with adult vignettes. The gender of the person described varied randomly.
On a scale of one to five, respondents were asked to indicate levels of agreement with two statements: 1. "Basically, we are all sometimes like this person. It's just a question of how pronounced this state is." 2. "All in all, the problems of Robert / Anne are abnormal." For both child and adult vignettes, two out of three respondents agreed that "we are all sometimes like this person." One in three respondents considered the problems depicted in the child vignettes as abnormal. That dropped to one in four in the adult vignettes.
Next, respondents were asked whether they ever had a problem like this and whether someone among their family or close friends ever had to deal with such a problem. For both vignettes, one in four acknowledged having had a problem like this, and half said a close friend or family member had such a problem.
On the assumption that "negative emotional reactions are an important consequence of negative stereotypes, leading to separation, discrimination and status loss," respondents were probed for their specific emotional reactions. "I feel annoyed," " react angrily," and" provokes my incomprehension" were interpreted as indicating varying levels of anger. "Provokes fear" and "Makes me feel insecure" were seen as indicating fear. "I feel uncomfortable" was viewed as indicating somewhere between fear and anger. On the other hand, "I feel the need to help," "I feel pity," and "I feel sympathy" were interpreted as "pro-social" responses.
Pro-social reactions were by far the most common. Over two-thirds felt a need to help a child, and over half to help an adult, in such a situation. In both instances, almost half felt sympathy, and a half or more felt pity. On the other hand, a quarter of respondents in each case felt annoyed, and just under one in five felt uncomfortable. Almost one in seven reacted angrily to the child vignette, and almost one in six to the adult vignette. Fear was the least frequent emotional reaction.
In the case of adults, respondents were also asked about their willingness to accept the person described in the vignette in seven social situations:
· Working together
· As a neighbor
· Marrying into the family
· Introducing to a friend
· Renting a room
· Recommending for a job
· Taking care of children
While three out of four respondents were willing to accept such persons as co-workers, only one in three would recommend them for a job. Two out of three would accept such persons as neighbors, and almost as many to marry into the family. Three out of five would very willingly introduce such persons to friends. Slightly over half would rent a room to them. But less than one in three would be willing to have such individuals take care of their children.
Older respondents were more likely to see the problems as "abnormal" and to seek greater social distance. Women, and respondents with higher levels of education, were less likely to see the problems as abnormal and more likely to respond in pro-social ways.
Though showing most Germans to be accepting of persons with ADHD, these findings still indicate a significant degree of stigma, though less than for other psychiatric conditions such as depression, schizophrenia, or alcohol dependence.

There has been consistent evidence of an association between ADHD and subjectively reported sleep problems even in patients not medicated for the disorder. There have also been studies using wrist-worn actigraphy (a wrist watch-like device that measures gross motor activity) and sleep lab-based polysomnography that measure objective sleep parameters.
What has been missing are large population-based cohort studies to explore the prevalence rates of different sleep disorders and medical prescriptions in ADHD.
Methods Used:
Sweden has a single-payer health insurance system and a series of national population registers that track virtually its entire population. Using the Swedish Total Population Register, a local research team created a cohort of all 6,470,658 persons born between 1945 and 2008. They linked this to the Swedish National Patient Register, which includes inpatient hospitalizations from 1975 to 2013, and outpatient specialist diagnoses from 2001 to 2013, to identify diagnoses of sleep disorders. They also linked to the Prescribed Drug Register, covering 2005 to 2013, to identify prescriptions for sleep medications.
Summary of Findings:
Overall, persons with ADHD were eight times more likely to be diagnosed with any sleep disorder relative to normally developing peers. Broken down by age, adolescents with ADHD were 16 times more likely to receive such diagnoses, young adults (18-30) twelve times more likely, children and mid-age adults (31-45) eight times more likely, and older adults six times more likely.
Broken down by specific sleep disorder diagnoses, relative to normally developing peers, persons with ADHD were:
As for sleep medication, relative to normally developing peers, persons with ADHD were:
Conclusion:
The team concluded, “Our findings also suggest that greater clinical attention should be directed towards addressing sleep problems in individuals with ADHD. This entails implementing proactive measures through sleep education programmes and providing both pharmacological and non-pharmacological approaches such as cognitive behavioural therapy and parental sleep training.”
Attention is a critical determinant of academic achievement, influencing domains such as language, literacy, and mathematics. To explore whether physical activity can improve attention in children with ADHD, an international team conducted a meta-analysis of peer-reviewed studies. The goal was to evaluate the impact of various physical activity regimens on attention-related outcomes in this population.
The researchers performed a comprehensive search of the medical literature to identify studies examining the effects of physical activity on attention in schoolchildren with ADHD. They included 10 studies with a total of 474 participants in their meta-analysis. The studies evaluated two main types of physical activity:
Additionally, they examined variations based on the frequency, duration, and type of control groups used in the studies. To assess consistency, they also analyzed heterogeneity (variability of outcomes) and checked for potential publication bias.
Key findings from the meta-analysis include:
The authors concluded that mentally engaging exercise is more effective than aerobic exercise in improving attention problems in schoolchildren with ADHD. Furthermore, higher frequency and longer duration of physical activity do not necessarily yield better outcomes.
This research underscores the importance of tailoring physical activity interventions to emphasize cognitive engagement over intensity or duration. By refining strategies, educators and parents can better support children with ADHD in achieving academic success. But take note: given the results from controlled studies, it seems clear that if there is a positive effect of exercise, it is very small so should not replace standard treatments for ADHD.

Previous studies have examined how stimulant medications affect the brain in controlled settings, but less is known about their impact in real-world conditions, where children may not always take their medication consistently or may combine it with other treatments. A new study leverages data from the Adolescent Brain Cognitive Development (ABCD) study to explore how real-world stimulant use impacts brain connectivity and ADHD symptoms over two years.
Changes in Brain Connectivity Researchers used brain imaging data from the ABCD study to examine the functional connectivity—communication between brain areas—of six regions within the striatum, a brain area involved in motivation and movement control. They focused on how stimulant use influenced connectivity between the striatum and other networks involved in executive functioning and visual-motor control.
The study found that stimulant exposure was linked to reduced connectivity between key striatal areas (such as the caudate and putamen) and large brain networks, including the frontoparietal and visual networks. These changes were more pronounced in children taking stimulants compared to those who were not medicated, as well as compared to typically developing children. Importantly, this reduction in connectivity seemed to regulate certain brain networks that are typically altered in children with ADHD.
Symptom Improvement In addition to brain changes, 14% of children taking stimulants experienced a significant reduction in ADHD symptoms over the two-year period. These children showed the strongest connectivity reductions between the right putamen and the visual network, suggesting that stimulant-induced connectivity changes may contribute to improvements in visual attentional control, which is a common challenge for children with ADHD.
Why This Matters This study is one of the first to examine how stimulant use in real-world conditions affects brain networks in children with ADHD over time. The findings suggest that stimulants may help normalize certain connectivity patterns associated with ADHD, particularly in networks related to attention and control. These insights could help clinicians better understand the potential long-term effects of stimulant treatment and guide personalized approaches to ADHD management.
Conclusion Stimulant medications appear to alter striatal-cortical connectivity in children with ADHD, with some changes linked to symptom improvement. This research highlights the potential for stimulant medications to impact brain networks in ways that support attention and control, highlighting the importance of understanding how real-world medication use influences ADHD treatment outcomes.
