Autism spectrum disorder, which is characterized by difficulties with social interaction and communication, as well as restricted interests and repetitive behaviors, has been increasing in recent years. Also, attention-deficit/hyperactivity disorder (ADHD), which is characterized by inattention, impulsivity, and hyperactivity, it is a neurodevelopmental disorder resulting from innate differences in brain development. In our center, specialists in pediatrics and psychiatry work collaboratively to focus on children's mental health, development, and social skills. We provide diagnosis and treatment for developmental concerns such as autism spectrum disorder, ADHD, and learning disabilities, as well as for mental health conditions including depression, anxiety disorders, eating disorders, school absenteeism, and trauma-related disorders. We serve children and adolescents who have developmental or mental health issues persisting from infancy, providing diagnoses based on thorough evaluations. We advise caregivers on how to interact with their children and what types of support to seek within the community. For the children themselves, we assess their specific characteristics, provide support to help them understand these traits when necessary, and offer assistance to foster independence. We also consider medication therapy as needed for difficult-to-treat sleep disorders, behavioral disorders such as panic, hyperactivity, and impulsivity, tics, anxiety, and depressive states.
