The increasing ubiquity of digital devices in childhood had outpaced the understanding of their effects on cognitive development, creating a significant research gap regarding their long-term impact. Objective: The present narrative overview explored the complex relationship between digital device usage and cognitive development in childhood. Methods: We conducted a comprehensive literature search across multiple databases, including PubMed, Embase, Scopus, and Web of Science, to critically assess cognitive domains such as attention, memory, executive functions, problem-solving skills, and social cognition. Incorporating over 157 peer-reviewed studies published between 2001 and 2024, we used strict inclusion and exclusion criteria to ensure scientific rigor. Results: The review integrated empirical findings with established theoretical frameworks, particularly from cognitive development and media psychology, to highlight both the advantages and risks of early, frequent exposure to technology. The potential for digital devices to enhance cognitive skills, such as multitasking and information processing, was weighed against risks such as cognitive overload, diminished attention spans, and impaired social skills. We also examined psychological and behavioral outcomes, including identity formation, emotional regulation, and maladaptive behaviors associated with excessive screen time. Additionally, we identified strategies to mitigate negative effects, emphasizing structured digital engagement and parental involvement to support healthy cognitive and psychological growth. Our findings provided actionable recommendations for parents, educators, and policymakers, promoting optimal digital practices that enhanced cognitive development while safeguarding against potential harms. Conclusions: The review offered essential insights for stakeholders in child development, education, and policy-making, highlighting the need for balanced integration of digital tools in childhood learning environments.

Background: Attention Deficit Hyperactivity Disorder (ADHD) has been described as a neurodevelopmental disorder characterized by inattention, hyperactivity, and impulsivity affecting cognitive, emotional, and social functioning. While pharmacological and behavioral treatments remain primary, physical activity (PA) (digital and non-digital versions) has emerged as a great complementary intervention due to its potential impact on executive functions, emotional regulation, and neurobiological markers. Objectives: This study aimed to assess the effects of PA on ADHD symptoms, executive function, and emotional regulation, exploring its potential impact and new practical applications in digital and non-digital treatment. Methods: This narrative review assessed 132 studies published between 1 January 2010 and January 2025, ensuring the inclusion of the most recent and relevant findings. The review was conducted in Scopus, PubMed, and Web of Science, using a predefined combination of terms related to ADHD, physical activity, executive function, neuroplasticity, and emotional regulation. Results: Regular PA improves executive functions, attention, inhibitory control, and cognitive flexibility in ADHD. Aerobic exercise enhances sustained attention, high-intensity training improves impulse control, and coordinative activities boost cognitive flexibility. Non-digital and digital innovations, such as exergaming and wearable fitness trackers, offer promising solutions to improve adherence to PA regimens, reinforcing their role as a key intervention in ADHD management. Conclusions: PA could be a valuable complementary intervention for ADHD through a hybrid approach that may improve cognitive and emotional functioning while addressing comorbidities.

Early diagnosis of child neglect is an ongoing challenge with consequences of the child’s safety, health, and effective referral for intervention. This study aims to obtain a selected set of family, maternal, and dyadic variables of the immediate caregiving environment for diagnosis, preventive, and intervention responses in healthcare settings. Mothers and their children under five years old: 51 in the neglected group (NG) and 89 in the non-neglected control group (CG), were recruited through pediatric primary care services and social services in Spain. Family demographics, adverse events, childhood maltreatment, maternal psychopathologies, personality variables, and observed mother–child interactions were assessed. Gradient boosting analyses were applied for the contributor’s relative importance (RI), followed by logistic regression and discriminant analyses for those with higher RI. Parametric analyses showed high diagnostic accuracy (80–82% of NG and 92% of CG) for risky factors of child neglect: having a physically neglected and depressed mother, living in families in need of financial assistance, and large families; and for protective factors: having an older mother and showing higher mother–child emotional availability. Identifying a select group of features makes early diagnosis and preventive intervention more effective for mitigating the impact of child neglect and building mother–child resilience.

Background: Childhood neglect is a pervasive yet often overlooked form of maltreatment that exerts profound and lasting effects on neurodevelopment. Unlike other types of abuse, neglect is characterized by the absence of essential stimuli and caregiving, which are critical for normal brain maturation, particularly in regions involved in executive function. Objective: This narrative review aims to critically explore the neurobiological mechanisms through which early-life neglect impairs the development of executive functions. Special emphasis is placed on alterations in brain structure and function, dysregulation of the hypothalamic–pituitary–adrenal (HPA) axis, and emerging epigenetic evidence. Methods: A comprehensive literature search (170 articles) was conducted across PubMed, Scopus, Web of Science, and PsycINFO, including studies published between 1 January 2000 to 31 March 2025. Relevant empirical and review articles were selected based on methodological rigor, relevance to executive functioning, and focus on child neglect. Results: Evidence reveals that neglect disrupts key neural circuits, particularly those involving the prefrontal cortex and amygdala, leading to deficits in attention, working memory, impulse control, and cognitive flexibility. Chronic stress associated with neglect also induces HPA axis dysregulation and elevated cortisol levels, which further compromise neural plasticity. Additionally, epigenetic modifications appear to mediate long-term cognitive and emotional consequences. Conclusions: Childhood neglect represents a distinct and critical risk factor for executive dysfunction. Understanding the neurodevelopmental consequences of neglect is essential for developing targeted prevention strategies and therapeutic interventions aimed at supporting cognitive resilience in affected populations.

Studies of DNA methylation have revealed the biological mechanisms by which life adversity confers risk for later physical and mental health problems. What remains unknown is the “biologically embedding” of maternal adverse experiences resulting in maladaptive parenting and whether these epigenetic effects are transmitted to the next generation. This study focuses on neglectful mothering indexed by a severe disregard for the basic and psychological needs of the child. Using the Illumina Human Methylation EPIC BeadChip in saliva samples, we identified genes with differentially methylated regions (DMRs) in those mothers with (n = 51), versus those without (n = 87), neglectful behavior that present similar DMRs patterns in their children being neglected versus non-neglected (n = 40 vs. 75). Mothers reported the emotional intensity of adverse life events. After covariate adjustment and multiple testing corrections, we identified 69 DMRs in the mother epigenome and 42 DMRs in the child epigenome that were simultaneously above the α = 0.01 threshold. The common set of nine DMRs contained genes related to childhood adversity, neonatal and infant diabetes, child neurobehavioral development and other health problems such as obesity, hypertension, cancer, posttraumatic stress, and the Alzheimer’s disease; four of the genes were associated with maternal life adversity. Identifying a shared epigenetic signature of neglect linked to maternal life adversity is an essential step in breaking the intergenerational transmission of one of the most common forms of childhood maltreatment.

DNA methylation clocks are used as molecular estimators of epigenetic age, but with little evidence in mothers and none in neglectful mothering. We investigated differences in epigenetic age acceleration (EAA) and the role of empathy using the PhenoAge clock. We collected saliva samples from mothers with extreme disregard for their child’s needs (50 in the neglect group, NG) and mothers with non-neglectful caregiving (87 in the control group, CG). Mothers completed an empathy scale, along with questionnaires of their own childhood maltreatment, adverse life events and psychiatric disorders. Sociodemographic variables potentially affecting EAA were also measured. The ANCOVA solution showed a significant increase in EAA in the NG compared to the CG, after adjustment for maternal age, number of pregnancies, financial assistance, adverse events, childhood maltreatment and psychiatric disorder. The group interaction effects showed a reduction in EAA for greater empathic concern and for a higher education level both as positive factors, and an increment in EAA for mothers living in a two-parent family as a risk factor, all in the NG. Our findings open the search for protective factors of EAA associated with caregiver behavior to reduce health vulnerabilities and poor social functioning, especially for mothers at risk of maladaptive caregiving.
