Attention-deficit/hyperactivity disorder: clinical phenotypes, polymorphism of life-course manifestations, and therapeutic strategies

Attention-deficit/hyperactivity disorder (ADHD) is a common neurobehavioral disorder that manifests in childhood and persists into adulthood. The prevalence of ADHD (USA/worldwide) in children and adolescents is 9.5/5.29 %, in adults — 4.4/2.5 %. The disorder has strong genetic correlations with numerous mental disorders and neurological diseases, in particular with post-traumatic stress disorder, addiction to cannabis, cocaine, recurrent and bipolar affective disorders, behavioral disorders, which is the biological basis of its clinical polymorbidity. Symptoms of ADHD overlap with other clinical manifestations of neurodevelopmental disorders (symptoms of autistic spectrum disorders, speech disorders, movement disorders, dyslexia, cognitive impairment), forming a polymorphic spectrum of pervasive developmental variants. Psychostimulants have been the standard of ADHD treatment for over 50 years. In 2002, atomoxetine became the first nonstimulant medication approved by the Food and Drug Administration for the treatment of ADHD, first in children and later in adult patients. Stimulant and nonstimulant medications have been shown to be effective in different phenotypes of ADHD (comorbidity with other mental and neurological disorders). In case of comorbidity of ADHD with anxiety, tics, atomoxetine has an advantage over stimulants and, together with alpha-2-adrenergic receptor agonists, can be recommended as the first drug. The presence of comorbid anxiety disorder or recurrent depression does not impact the efficacy and side effects of atomoxetine. Thus, atomoxetine is an effective drug and not only improves the symptoms of ADHD, but also plays a certain role in the treatment of patients with comorbid depression and anxiety.

Screen time and effects on attention deficient hyperactivity disorder in children - A systematic review

In recent years, screen time exposure and attention-deficit hyperactivity disorder (ADHD) symptom interrelations in children have garnered increasing attention. Understanding the screen time’s impact on ADHD has become crucial due to its potential influence on socialization, neurobehavioral development, and the prevalence of ADHD among pediatric populations. Conforming to the guidelines of the preferred reporting items for systematic reviews and meta-analyses, a systematic examination was undertaken, centering on research investigating the correlation between screen time and ADHD symptoms in children. The search encompassed databases including MEDLINE (through PubMed), ScienceDirect, Wiley online library, PsycINFO, ERIC, JSTOR, and PsycArticles, utilizing descriptors such as “screen time” and “attention-deficit hyperactivity disorder.” The initial search yielded 2480 articles, supplemented by an additional 10 articles from reference searches, resulting in a total of 2480 records. Excluding the duplicates, 1590 articles were screened based on abstracts, of which 130 underwent full-text examination. Ultimately, 15 studies included in this review met the inclusion criteria. These studies, conducted between 2013 and 2023, comprised cross-sectional, longitudinal, and interventional designs, presenting varying associations between screen time and ADHD symptoms across different age groups. The findings from the selected studies depict a complex relationship between screen time exposure and ADHD symptoms in children. While some studies highlight significant correlations between increased screen exposure and ADHD symptoms, others present conflicting results, indicating the need for further research. Understanding these nuances is crucial in formulating targeted interventions and delineating clearer guidelines to manage screen time concerning ADHD in children.

Listening Comprehension Skills in Children with Attention Deficit and Hyperactivity Disorder: A Review Study

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterised by symptoms of inattention, hyperactivity and impulsivity that may begin in early childhood and continue into adolescence and adulthood and are incompatible with the developmental level of the individual. Most children with ADHD are at risk of facing significant academic problems throughout their educational life. In recent studies aiming to reveal the causes of academic problems experienced by children with ADHD, academic problems have been associated with the difficulties in reading and listening comprehension skills of children with ADHD. The relatively common prevalence of ADHD, the extent of academic problems experienced by children with ADHD, and the lack of clarity about reading difficulties require further examination of the relationship between ADHD and reading and listening comprehension skills, which are often based on the same language and cognitive skills. Listening comprehension, which is defined as the ability to understand, interpret, organise and evaluate the ideas and thoughts in a speech heard or a text read aloud, is one of the most important early literacy skills necessary for the ultimate goal of reading, which is reading comprehension. In this review study, listening comprehension skills of children with ADHD were discussed together with the literature.

Changes in parental attitudes toward attention‐deficit/hyperactivity disorder impairment over time

AbstractBackgroundOver the last decades, the prevalence of Attention‐deficit/hyperactivity disorder (ADHD) has increased. However, the underlying explanation for this increase remains unclear. We aimed to assess whether there has been a secular change in how parents perceive the impairment conferred by ADHD symptomatology.MethodsData for this study were obtained from the Child and Adolescent Twin Study in Sweden, involving 27,240 individuals whose parents answered a questionnaire when the children were 9 years old. We assessed the relationship between parentally perceived impairment caused by ADHD symptoms scores over time. The analysis was performed separately for five different birth cohorts, spanning three‐year periods from 1995 to 2009 and for ADHD inattention and hyperactivity/impulsivity dimensions.ResultsWe found a consistent upward trend of parents reporting impairment in relation to ADHD symptomatology across birth cohorts. Over a 12‐year period, comparing those born 2007–2009 (assessed 2016–2018) with those born 1995–1997 (assessed 2004–2006), impairment scores increased by 27% at clinically relevant levels of ADHD symptomatology. Notably, when specifically evaluating the hyperactivity/impulsivity dimension, the disparity was even more striking, with an increase of up to 77%.ConclusionsThis study revealed a significant secular change in parental perception of impairment attributed to ADHD symptomatology over recent decades, providing new insights into the increased prevalence of ADHD. It underscores the need to better understand the factors that have contributed to the increased perception of impairment related to ADHD symptoms.

Prevalence of attention-deficit hyperactivity disorder in adult prisoners: An updated meta-analysis.

Previous meta-analyses may have overestimated the prevalence of attention-deficit hyperactivity disorder (ADHD) in prisoners by including data from selected samples. To estimate the prevalence of ADHD in unselected samples of adults in prison and examine potential sources of heterogeneity by meta-regression and subgroup analyses. We assessed all studies included in a 2018 systematic review for eligibility and updated the literature search to include studies published up to September 2023. A total of 11 studies reporting robust diagnostic data on ADHD in 3919 unselected adults in prison were included. In meta-regression, ADHD prevalence did not differ between men and women but it was significantly higher in studies using a two-phase design. In random sampling studies, the pooled prevalence of ADHD was 8.3% (95% CI: 3.8-12.8) which was further halved after the removal of an outlier. One in 12 adults in prison have been diagnosed with ADHD. Our findings highlight the importance of using clear and consistent inclusion criteria in meta-analyses of prevalence.

Entrepreneurial mental health in the wake of COVID-19 in China with an emphasis on attention deficit hyperactivity disorder (ADHD) and dyslexia analysis

The COVID-19 pandemic has precipitated a global mental health crisis, with a particularly pronounced impact on the entrepreneurial sector. This paper presents a comparative analysis of mental health challenges among entrepreneurs in China during the pandemic, with a specific focus on attention deficit hyperactivity disorder (ADHD) and Dyslexia. The study assesses the prevalence of ADHD and dyslexia symptoms among established and emerging entrepreneurs in China, finding notable occurrences within this group. The research also examines the self-care practices of these entrepreneurs, shedding light on their approaches during the pandemic period. The findings highlight a complex interplay between mental health issues and entrepreneurial activities, suggesting that certain ADHD and dyslexia traits may offer unexpected benefits in the entrepreneurial realm. These insights are critical for developing supportive frameworks that leverage the strengths of neurodiverse entrepreneurs while mitigating associated challenges, especially in a post-pandemic economic landscape. The study concludes with policy and practice recommendations to bolster the wellbeing and resilience of entrepreneurs facing the multifaceted impacts of the pandemic.

ADHD and family life: A cross-sectional study of ADHD prevalence among pupils in China and factors associated with parental depression.

Attention Deficit Hyperactivity Disorder (ADHD) is increasingly recognized as a major problem for children and their families in China. However, its influence on parental mental health has been seldom explored. To examine the prevalence of attention deficit hyperactivity disorder in a community sample of children aged 6-13 years, and the extent to which it impacts parental mental health. Cross-sectional study of primary school pupils (number = 2497) in Deyang, Sichuan Province, South-West China. We used standardized instruments to identify children with ADHD symptoms and parent depression. The prevalence of ADHD was 9.8%. Factors associated with the likelihood of ADHD, included family environment(P = 0.003), time spent with children(P = 0.01), parenting style(P = 0.01), and parental relationship, pupils self-harm and lower academic ability (P = 0.001). After controlling for other factors, having a child with ADHD increased the likelihood of parents' depression (OR = 4.35, CI = 2.68~7.07), additional factors included parent relationship. ADHD may be a common disorder among Chinese children, the symptoms of which may increase the likelihood of parent depression. There is a need for greater detection of ADHD in schools, acknowledgement of the challenges the disorder creates for academic success and family wellbeing, and psychoeducational tools for supporting parents of children with ADHD.

Suspected geriatric onset of attention-deficit/hyperactivity disorder in a patient with comorbid bipolar disorder

BackgroundAn increasing number of adults over 60 years old are presenting with requests for treatment of attention-deficit/hyperactivity disorder (ADHD). However, the prevalence of ADHD in older adults in geriatrics is unknown. Further, comorbid bipolar disorder and adult ADHD are likely underrecognized with many patients only receiving treatment for one of these conditions. The occurrence of bipolar disorder with geriatric onset ADHD is unknown.Case presentationA 64-year-old Hispanic woman with a psychiatric history of bipolar I disorder (diagnosed in early adulthood) was diagnosed with ADHD suspected of geriatric onset, and able to be successfully managed on concurrent mood stabilizers and psychostimulant medication.ConclusionsThe findings of this case report emphasize the importance of appropriately recognizing and treating comorbid ADHD and bipolar disorder in any age group, including the geriatric population for which this occurrence appears to be very rare. Additionally, this case report demonstrates the safe utilization of psychostimulant medications in a geriatric patient with bipolar disorder without inducing a manic episode or other significant adverse reactions.

Rising Trends of Childhood Attention-Deficit/Hyperactivity Disorder in a Large Integrated Healthcare Delivery System in Southern California, 2010-2021

ObjectiveTo evaluate trends of attention-deficit/hyperactivity disorder (ADHD) diagnosis rates among children aged 5-17 years over the past decade (2010-2021) and to investigate whether there have been differences in temporal changes based on race and ethnicity, sex, or income Study designChildhood ADHD diagnosis was ascertained from electronic health records using ICD-9 (314.xx) and ICD-10 (F90.x) codes. Data were stratified by child’s sex, race and ethnicity, and household income, and rates of ADHD were estimated before and after adjustment for potential confounders. ResultsThe overall ADHD diagnosis rates increased from 3.5% in 2010 to 4.0% in 2021. ADHD diagnosis was most prevalent among White children (6.1%), then Black (4.6%), Other/multiple (3.7%), Hispanic (3.1%), and Asian/Pacific Islander (PI) (1.7%). ADHD was also highly prevalent among boys (73.3%) or family income≥$70,000 (50.0%). ADHD diagnosis increased among Black (4.2% to 5.1%), Hispanic (2.8% to 3.6%) ,and Asian/PI children (1.5% to 2.0%) but remained stable for White (6.2% to 6.1%) and Other/multiple race/ethnic children (3.7% to 3.7%). Increases in the prevalence among girls were also observed. ConclusionThe prevalence of ADHD in children has risen with the largest increases observed for Black, Hispanic, and Asian/PI children. Rates among less affluent families and girls have also been increasing, narrowing the gaps in diagnosis rates previously observed. These increases may reflect improvements in screening and provision of care among demographics where ADHD has been historically underdiagnosed.

Attention deficit hyperactivity disorder in the diabetic population: relationship with metabolic syndrome and atherogenic index of plasma

Aims: The objective of the current study is to investigate the prevalence of Attention Deficit/Hyperactivity Disorder (ADHD) among individuals diagnosed with diabetes mellitus (DM). Additionally, this study aims to evaluate the potential association between ADHD and metabolic syndrome (MetS), atherogenic index of plasma (AIP), and other lipid parameters, considering the different types of DM. Methods: The study comprised 213 adult patients diagnosed with diabetes mellitus, consisting of 120 females and 93 males. Participants completed the Adult Attention Deficit Hyperactivity Disorder Self-Report Scale (ASRS) as a screening tool for symptoms. The study assessed many physiological indicators, including body mass index, waist circumference, blood pressure, glucose levels, cholesterol levels, high-density lipoprotein levels, low-density lipoprotein levels, triglyceride levels, uric acid levels, and glycated hemoglobin levels. Results: The study yielded a prevalence rate of 10.7% for ADHD among diabetes individuals. The prevalence of ADHD was found to be more common in individuals diagnosed with type 1 diabetes mellitus (T1DM) compared to those with type 2 diabetes mellitus (T2DM), with rates of 15.4% and 9.8% respectively. The study revealed that individuals diagnosed with T2DM who also had MetS, organ involvement, concurrent disorders, and stress-related eating had significantly higher scores on the ASRS/T scale. There was a correlation observed between the ASRS-HI and AIP levels in individuals diagnosed with T2DM. The statistical analysis revealed that ADHD-HI and T scores significantly influenced the severity of MetS. A progressive increase in ASRS/T and ASRS/I scores was observed with the duration of DM. Conclusion: In conclusion, by recognizing and treating accompanying neuropsychiatric conditions such as ADHD symptoms in diabetic patients, individuals may exhibit improved adherence to lifestyle modifications and antidiabetic therapies. This approach potentially reduces the risks of acute and chronic complications, including cardiovascular risk, through the enhanced management of DM.

The Population of Children with High Risk of ADHD and The Mother’s Sociodemographic Profile in Surabaya

Objective: Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder with several symptoms in the form of inattention, hyperactivity, and impulsivity. There are no official data regarding the prevalence of ADHD in Indonesia, and data in regards to ADHD prevalences are limited to several studies. This study aims to give perspective on the prevalence of children’s ADHD risk in Surabaya. Methods: This study was conducted at three elementary schools in Surabaya. All students between grades 3 to 6 were invited as participants in this study, with the forms being filled out by their mother. The risk of ADHD is measured with SPPAHI. Additionally, we also collected the mothers’ sociodemographic data. Result: Among the 358 mothers, there were 54 mothers (15,1%) who had children with ADHD symptoms, as evidenced by a questionnaire score on the Hyperactive and Impulsive Child Behavior Assessment Scale (SPPAHI) >30. Conclusions: Further research and examination are required to properly diagnose ADHD in children.

Onverwacht uterien bloedverlies bij methylfenidaat

Unexpected methylphenidate-induced uterine bleeding In most countries, methylphenidate appears to be the main pharmacological treatment for attention deficit hyperactivity disorder (ADHD). The global prevalence of ADHD is estimated to be approximately 2.5% in adults and 5-7% in children. This case report examines the link between the initiation of extended-release methylphenidate and the occurrence of unexpected uterine bleeding in a patient, aiming to determine if there is any scientific basis for considering this symptom as a side effect of methylphenidate. Although there are some suspicions in the literature, the evidence is still too limited to explain a causal relationship between methylphenidate and unexpected uterine bleeding. In recent years, scientific studies have shown a growing awareness of ADHD in the female population, while women and girls were previously diagnosed with ADHD much less frequently and much later. However, this phenomenon of underrepresentation of women still occurs in the available scientific literature, especially in somewhat older studies. In future research, an important challenge lies in further monitoring any potential effects of methylphenidate on the female reproductive system, adequately reporting contraceptive use in study populations, as well as detailing all adverse events and reasons for study dropouts.

Attention-Deficit Hyperactivity Disorder among children of immigrants: immigrant generation and family poverty

ABSTRACT Objectives: Attention-Deficit Hyperactivity Disorder (ADHD) is one of the most common disorders diagnosed among children in the US. However, little knowledge is available about ADHD prevalence among children of immigrants, the fastest-growing population in the US. This study seeks to examine ADHD rates among children of immigrants in different generations compared to children of US-born parents and their association with family poverty. Design: The sample includes 83,362 children aged 0–17 from the National Health Interview Survey (NHIS) 2010–2018 data. Multivariate logistic regression model is used to estimate prevalence of ADHD among children of immigrants compared to children of US-born parents. We then compare ADHD rates among the children sample in different immigrant generations. For all analyses, we examine ADHD occurrence separately for children in families living below the poverty threshold and those at or above the poverty threshold. Results: The odds of having ADHD were significantly lower among children of immigrants compared to children of US-born parents. Both first-generation children and second-generation children of immigrants had significantly lower odds of having ADHD than children of US-born parents. Post hoc tests find that first-generation children had lower odds of having ADHD compared to second-generation children. Likewise, additional analyses showed that children of immigrants, first-generation children in particular, were less likely to have ADHD compared to children of US-born parents, in both lower- and higher-income families. Conclusion: Using a nationally representative sample of children, we find that the likelihood of having ADHD increases with higher generations, detecting differences in ADHD prevalence by immigration generation. Importantly, first-generation children had a significantly lower risk of having ADHD conditions compared to second-generation children and children of US-born parents, regardless of family socio-economic status. Public health policy and program development would gain from a clear comprehension of the shielding attributes of ADHD among immigrant families.

Prevalence of Undiagnosed Attention Deficit Hyperactivity Disorder (ADHD) Symptoms in the Young Adult Population of the United Arab Emirates: A National Cross-Sectional Study

BackgroundAttention deficit hyperactivity disorder (ADHD), a globally prevalent behavioural disorder, remains underdiagnosed, particularly among adults. This issue is exacerbated in the Arab region due to stigma and insufficient healthcare facilities and professionals. Despite the United Arab Emirates (UAE) efforts to improve mental healthcare, shortcomings persist. No studies in the UAE currently assesses the appropriateness of the screening system for ADHD and other behavioural issues. Furthermore, prevalence rates of ADHD, particularly within the young adult population, are absent.AimTo estimate the prevalence of ADHD amongst young adults attending university in UAE and examine its relationship with gender and academic outcomes.MethodsA cross-sectional, correlational design was used. Young adults in their first year at university were recruited from different academic institutions across the UAE. The study utilized the Adult ADHD Self-Report Scale (ASRS) for data collection.ResultsA sample of 406 young adults, aged between 18 and 20 years of age were recruited. Approximately, 34.7% (n = 141) reported symptoms suggestive of probable ADHD. Significantly lower grade point average marks were observed in participants with ADHD symptoms (M = 3.15) compared to those without (M = 3.35). Females reported symptoms of probable ADHD at higher rates than males, indicating possibly a potential screening deficiency and a potential stigma consequence.ConclusionsThe study demonstrates a high prevalence of probable ADHD in young adults, particularly among females attending university in the United Arab Emirates. Implications for early screening, service provision, and greater professional health training on this disorder are required.

Prevalence of ADHD and factors for parent's participation in the care of children with ADHD, Yasothon, Thailand.

Attention deficit hyperactivity disorder (ADHD) is a mental health disorder commonly observed in children. Parents' participation in the care (PPC) of children with ADHD (C-ADHD) is especially important to promote support care and treatment. We estimated the prevalence of C-ADHD and identified the factors for the PPC of C-ADHD. A cross-sectional analytic study was conducted on parents and grade-one students in five primary schools, Muang district, Yasothon, Thailand. The study was conducted from March to June 2022. Data were collected using the screening test of SNAP-IV Thai version and by interviewing child psychiatrists and parents. Descriptive statistics were used to summarize the demographic data and prevalence of C-ADHD. Unconditional multiple logistic regression was used to identify predictive statistical model for the PPC of C-ADHD. Four hundred sixty-four students were screened by SNAP-IV, of which 30 students were confirmed as ADHD (6.5% [95% confidence interval [CI]: 4.4-9.1]), with 9.1% boys and 3.6% girls. Four factors associated with the PPC of C-ADHD significantly including male (ORadj: 2.5, 95% CI: 1.4-4.4), single divorce status (ORadj: 2.1, 95% CI: 1.1-4.2), income more than 15,000 baht (ORadj: 3.1, 95% CI: 1.8-5.1), and attitude level during middle-high (ORadj: 8.4, 95% CI: 5.0-14.2). Predictive factors of four variables can be used to implement the policy to improve the healthcare system, prevention, and PPC of C-ADHD.

Medical education: Accommodating students with ADHD

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that affects a significant number of medical students worldwide. It is poorly recognised by educators, and therefore inadequately accommodated for in educational strategies. In order to investigate this further, a literature review and pilot survey were conducted. Health educators employed by The University of Newcastle, Australia, completed a short online survey, which focused on their understanding of, and ability to recognise and adapt teaching strategies for students with ADHD. The results of the survey informed the development of a resource that provided evidence-based strategies for supporting the learning of tertiary students with ADHD. In addition, the results of this pilot study may form the basis for further research in this domain. Given the prevalence and potential impact of ADHD on higher education, it is important to gain deeper insight into how medical educators can best engage and support students with ADHD. This knowledge may potentially reduce the negative impacts of this neurodiversity on students and support their learning and well-being throughout their medical career. Ultimately this may help doctors to achieve their full potential, especially in clinical decision-making.

Prevalence and Comorbidities of Adult Attention-deficit/hyperactivity Disorder in a Community Sample from Korea.

: Attention-deficit/hyperactivity disorder (ADHD) is prevalent in adults, and psychiatric comorbidities are common in adults with ADHD. We aimed to examine the prevalence of adult ADHD with several common psychiatric conditions in a community sample in Korea and the association between adult ADHD and risk of psychiatric comorbidities. : This study used a cross-sectional survey design. We provided supplementary and optional self-report questionnaires, including the Korean version of the World Health Organization Adult ADHD Self-Report Scale (ASRS) short screening scale, Patient Health Questionnaire-9 for screening for depression, Alcohol Use Disorders Identification Test alcohol consumption questions, and the Korean version of the Mood Disorders Questionnaire, to Korean adults who visited one of six centers of a large private healthcare company for the National General Health Examination. : A total of 17,799 subjects included in this study, and 430 (2.4%) were positive on the ASRS screen. ADHD was significantly associated with the 19-30-year-old age group (odds ratio [OR] = 3.938), lower income (OR = 1.298), depression (OR = 11.563), and bipolar disorder (OR = 3.162). : Adult ADHD was highly associated with depression and bipolar disorder, suggesting that clinicians should carefully evaluate and treat such psychiatric disorders in adults with ADHD symptoms.

Are congenital heart defects connected to more severe attention-deficit/hyperactivity disorder?: A systematic review and meta-analysis.

Congenital heart defects (CHDs) are the most common cause of birth defect-related infant morbidity and mortality, affecting 1% of 40,000 births per year in the United States. On the other side, the etiology of attention-deficit/hyperactivity disorder (ADHD) is multifactorial. Multiple studies have found that cardiac surgery patients have higher morbidity of having this disorder. Many studies have investigated the prevalence of ADHD in different subtypes of CHD, but few have focused on the severity of ADHD symptoms. Thus, we conducted this systematic review and meta-analysis to investigate the severity of ADHD symptoms in CHD patients. We searched PubMed, Embase, Scopus, and Web of Science were searched from inception to March 6, 2023 without any restrictions. We included observational studies published in English language that evaluated burden of symptom of ADHD in CHD patients. Moreover, the standardized mean difference (SMD) for continuous outcomes with 95% confidence interval (CI) was pooled. P-values <.05 are considered as significant, and we performed all statistical analyses using RevMan software Version 5.4.1. Eight studies were included in our review with a total number of 120,158 patients. CHD was associated with a statistically significant increase in both ADHD index T score and ADHD Hyperactivity-Impulsivity Subscale (informant) with (SMD = 0.65, 95% CI [0.40, 0.90], P < .00001, I2 = 81%) and (SMD = 0.16, 95% CI [0.04, 0.28], P = .008, I2 = 0%). Regarding ADHD Inattention Subscale (informant), the pooled data showed that a significant increase of this score in the CHD group (SMD = 0.25, 95% CI [0.13, 0.37], P < .001, I2 = 0%), and ADHD Combined Score (informant) showed a significant increase of this score in the CHD group (SMD = 0.23, 95% CI [0.11, 0.35], P = .0002, I2 = 0%). Our study revealed a strong association between CHD and not only ADHD, but also the severity of ADHD, making early diagnosis of ADHD in children with CHD a mandatory step in the clinical evaluation practice to improve these children on both clinical and psychological aspects.
