Short Research Article: Impact of a prolonged lockdown on the symptoms of paediatric ADHD and common associated disorders

Psychological distress and related factors among caregivers of children with attention-deficit/hyperactivity disorder during the COVID-19 pandemic

The present study examined the relationships of caregiver factors (including caregivers' age, sex and educational year), child-family interactions (caregivers' difficulties in managing children's protective behaviors against COVID-19, learning and daily performance, children's conflict with elders and siblings, and parenting styles), and children's factors (attention-deficit/hyperactivity disorder [ADHD] and oppositional defiant disorder [ODD] symptoms) with psychological distress of the caregivers of children with ADHD in the COVID-19 pandemic. This study recruited 252 caregivers of children with ADHD to participate and complete a questionnaire collecting their psychological distress in the COVID-19 pandemic, demographics, difficulties in managing children's protective behaviors against COVID-19, learning and daily performance, and parenting styles as well as children's conflict with elders and siblings, and the ADHD and ODD symptoms. Hierarchical regression models were constructed to examine the factors related to psychological distress among caregivers. Factors across caregiver, child, and child-family interaction dimensions, including children's conflict levels with elders and siblings, inattention symptoms, and caregivers' difficulties in managing children's protective behaviors against COVID-19, learning and daily performance, female sex, and younger age were significantly associated with psychological distress among caregivers in various hierarchical regression models. Health professionals should take the relevant factors identified in this study when developing an intervention to relieve caregivers' psychological distress in the COVID-19 pandemic.

Consequences of the Covid-19 pandemic in children and adolescents with attention deficit hyperactivity disorder - a systematic review

OBJECTIVE

In this systematic review (SR), the authors aimed to identify the possible impact of the social restriction imposed by the Coronavirus Disease-19 (COVID-19) pandemic on children/adolescents with Attention Deficit Hyperactivity Disorder (ADHD).

DATA SOURCES

This SR was registered on PROSPERO CRD42021255569. Eligible articles were selected from PubMed, Embase, and LILACS, according to the following characteristics: ADHD patients < 18 years old, exposed to the COVID-19 pandemic, and the outcomes, medications, relationships, sleep, media use, remote learning, and comorbidities such as depression/sadness, inattention, anxiety, and irritability/aggressiveness. Newcastle-Ottawa Scale (NOS) for cohort, cross-sectional and case-control studies was used to assess methodological quality and the risk of bias.

SUMMARY OF FINDINGS

Of the 222 articles identified, 27 were included, with information on 7,235 patients. Most studies (n = 22) were cross-sectional and received a mean NOS 4.63/10 followed by longitudinal (n = 4) with 3.75/8 points and case-control (n = 1), with 3/9 points. The pandemic affected patients' access to treatment, behavior, and sleep. Difficulties in remote learning and increased use of social media were described, as well as significant and positive changes in relationships with family and peers.

CONCLUSION

Although the studies were heterogeneous, they indicated that the pandemic-related issues experienced by patients with ADHD were mostly manifested affecting their behavior and sleep patterns.

Mental health during the COVID-19 pandemic in children and adolescents with ADHD: A systematic review of controlled longitudinal cohort studies

Prior studies reported mixed effects of the COVID-19 pandemic on the mental health of children and adolescents with ADHD, but they were mainly cross-sectional and without controls. To clarify the impact, we searched Web of Science, EMBASE, Medline, and PsychINFO until 18/11/2023 and conducted a systematic review of controlled longitudinal cohort studies (Prospero: CRD42022308166). The Newcastle-Ottawa scale was used to assess quality. We identified 6 studies. Worsening of mental health symptoms was more evident in ADHD or control group according to symptom considered and context. However, those with ADHD had more persistent elevated symptoms and remained an at-risk population. Sleep problems deteriorated more significantly in those with ADHD. Lower pre-COVID emotion regulation skills and greater rumination were associated with worse mental health outcomes, and longer screen time with poorer sleep. Quality was rated as low in most studies, mainly due to self-report outcome measures and no information on attrition rates. Despite these limitations, results suggest a predominantly negative impact on youths with ADHD and may guide clinical practice and policy.

Changes in sleep duration and disturbances during Covid-19 lockdown and internalizing-externalizing behaviors in children with attention deficit hyperactivity disorders

OBJECTIVE

To examine how changes in sleep patterns and sleep problems occurring between the pre-pandemic and the Covid-19 lockdown period influenced mood-behavioral functioning of children with Attention Deficit Hyperactivity Disorder (ADHD).

METHODS

Parents of 992 children with ADHD (85.4% boys, mean age: 11.52 years, SD = 3.17), recruited from the Italian ADHD family association, completed a modified version of the Sleep Disturbance Scale for Children and filled out 11 emotional behavioral items selected from the Child Behavior Checklist (CBCL) 6-18 questionnaire. Subgroups identified based on sleep duration changes ("maintained", "increased", "reduced") and of sleep problems during lockdown ("onset", "remission", "maintained", "no sleep problem") were analyzed to evaluate the association with internalizing and externalizing scores.

RESULTS

Sleep duration showed no or low influence on internalizing and externalizing behaviors after control for age, sex, and socioeconomic status. Patients with ADHD with "no sleep problem" showed significant lower scores in internalizing and externalizing behaviors than those who "maintained" or had "onset" of different sleep problems. The effect sizes were higher for internalizing than externalizing behaviors. Lower internalizing scores were found in those who remitted difficulty in falling asleep, daytime sleepiness, nightmares, vs. the "maintained" or "onset" groups and those who remitted hypnic jerks vs. the "onset" group. Children with ADHD who "maintained" sleep terrors reported higher internalizing and mainly externalizing scores than the other groups.

CONCLUSION

Sleep problems negatively influence daytime functioning of patients with ADHD. but mood and behavioral domains show different susceptibility to the changes of sleep problems, and different vulnerability to specific sleep problems.
