      <abstract>
        <p>This article critically examines the potential benefits of utilizing Virtual Reality (VR) in the rehabilitation of children diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). ADHD, prevalent among children aged 3 to 5, presents significant challenges in education, social interactions, and interpersonal relationships. Several studies indicate that VR technology serves as a valuable tool in addressing these challenges by offering adaptable solutions tailored to each child's unique needs, establishing a secure and focused environment. VR actively engages children, providing effective tools for behavioral assessments, facilitating comprehension and amelioration of cognitive deficits. It aids therapists in precise diagnosis and assessment while improving working memory, executive functions, and attention. The application of VR in the rehabilitation of children with ADHD, grounded in behavioral and physical models, is especially advantageous as it replicates virtual environments for diagnostic purposes, training sessions, ongoing monitoring, and therapeutic interventions.</p>

        2. The Impact of Virtual Reality in ADHD Patient Rehabilitation
Virtual Reality (VR) is a technology that emulates imaginary or real environments [15,16]. Allowing
users to interact in three-dimensional settings, VR finds applications in education, entertainment,
medical, surgical, etc. [15,17,18]. This is because this technology has the capability to easily create
environments similar to real life [
        <xref ref-type="bibr" rid="ref5">5,19,20</xref>
        ]. Among various types, immersive VR, desktop VR,
projective VR, and CAVE (C-Automatic Virtual Environment) are among the most common [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ].
Some key advantages offered by VR include high motivation in patients, environment
customization according to needs, stability between users and stimuli, complete recording of
patients' behaviors and functionalities, facilitating rapid feedback, and ensuring time and cost
savings [
        <xref ref-type="bibr" rid="ref5">5,19</xref>
        ]. In terms of rehabilitation, VR enables individuals with disabilities caused by brain
damage to confront experiences that are difficult or impossible to experience in the real context
[21,22]. However, a significant obstacle arising from the use of rehabilitation technologies in virtual
environments is a psychophysiological issue [25,26]. Indeed, during a virtual reality session, users
may experience discomfort such as headaches, seizures, nausea, etc. [23,24].
      </p>
      <p>
        Virtual reality (VR) proves to be an effe ctive tool in the rehabilitation of patients with ADHD,
allowing a more reliable assessment of cognitive processes through neuropsychological tests such
as the Continuous Performance Test (CPT) [27,28]. Some studies indicate that the CPT integrated
into VR (VRC-CPT) provides greater ecological validity and is preferred by children with ADHD
compared to the traditional CPT [29]. The combination of virtual reality and interactive tests, with
specific stimuli, proves useful in removing distractions and maintaining the attention and
concentration of patients, contributing to the rehabilitation of children with ADHD
[
        <xref ref-type="bibr" rid="ref5">5,19,30,31,32,33</xref>
        ]. Virtual reality environments enable the detection of cognitive deficits [29]. The
utilization of virtual reality (VR) technologies, like computer-generated graphics emulating the
actual world, diminishes disruptions in the daily routines of individuals, facilitating the transfer of
skills acquired within the VR environment to real-world situations[34,35,36].
      </p>
      <p>
        A meta-analysis conducted by Bashiri et al. ( 2017) revealed that many professionals, including
doctors and therapists, are adopting VR systems for clinical rehabilitation. Rehabilitation therapies
based on virtual reality employ strategies that take into account interaction, system usability, and
user perceptions. They offer specific stimuli that can be utilized to eliminate distractions and create
safe environments that capture the subjects' attention, thereby enhancing their concentration
abilities [32,33]. Regarding challenges in cognitive performance, such as working memory,
executive function, and attention in children with ADHD, literature highlights that VR technologies
are extremely useful for assessing, providing instruction, and improving these conditions. They
offer a stable virtual environment that allows patients to adapt their lifestyle through cognitive
training [15,28,37,38,39]. Often, children with ADHD experience difficulties in problem-solving,
behavior management, and cognitive adaptability [19]. Behavioral models play a crucial role in the
rehabilitation process for individuals with ADHD, demonstrating significant importance in virtual
reality-involved therapies. VR technologies facilitate action-based responses in these children,
helping to reduce behavioral symptoms and problems [34,40]. Other studies have indicated VR's
ability to enhance memory functionality, sensory processing, and the five levels of attention,
including focused, sustained, selective, alternating, and divided attention in individuals with ADHD
[
        <xref ref-type="bibr" rid="ref1">1,15</xref>
        ].Some research, concerning the ecological relevance of neuropsychological tests, suggests that
integrating these tests into virtual reality contexts increases both ecological validity and the ability
to transfer skills and knowledge acquired from the virtual environment to the real world
[
        <xref ref-type="bibr" rid="ref5">5,19,29,30,32,33</xref>
        ]. A key point underscoring the importance of virtual reality technologies is that
using medication within virtual contexts proves more effective than in non-virtual environments,
contributing to reducing omission errors and reaction times during the assessment of children with
ADHD [41]. Based on these results, it appears that VR games express a wide range of human
emotions and are particularly effective in rehabilitating children with ADHD [45]. Furthermore, the
use of a virtual classroom in VR, simulating the school environment, and the inclusion of
neuropsychological tests, such as the CPT, exhibit higher ecological validity in this context
[19,30,31,42]. Despite the various opportunities offered by VR technologies, potential side effects
pose a challenge that can threaten the health and safety of children with ADHD. However, this
issue is partially manageable through the customization of VR according to user needs, proper
calibration, and the use of suitable user interfaces and head-mounted displays [23,25,43,44].
3. Conclusion
In conclusion, ADHD presents challenges that significantly impact the daily lives and development
of affected individuals. Traditional rehabilitation approaches involve medical therapies,
psychological counseling, and behavioral interventions, but emerging technologies, particularly VR,
offer innovative strategies for ADHD rehabilitation [45]. VR, with its diverse applications, provides
a unique platform for creating immersive environments that cater to individual needs, enhancing
motivation, and offering a more reliable assessment of cognitive processes. The integration of
neuropsychological tests into VR environments, such as the Virtual Reality Continuous
Performance Test (VRC-CPT), not only proves more engaging for children with ADHD but also
demonstrates greater ecological validity compared to traditional methods. The interactive nature of
VR environments facilitates focused attention and concentration, contributing to the reduction of
behavioral symptoms and the improvement of cognitive functions. Despite the evident benefits,
challenges such as psychophysiological issues and potential side effects need careful consideration.
Nonetheless, advancements in customization, calibration, and suitable interfaces offer promising
avenues to manage these concerns [47]. The potential of VR technologies to bridge the gap between
virtual and real-world scenarios, coupled with their ability to enhance memory functionality and
attention levels, underscores their significance in the rehabilitation of children with ADHD. As
professionals increasingly adopt VR systems for clinical rehabilitation, it is crucial to navigate the
balance between therapeutic efficacy and ensuring the health and safety of individuals with ADHD
in virtual environments.
