Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by symptoms of inattention, hyperactivity, and impulsivity that significantly impact an individual's daily functioning and quality of life. The disorder typically presents in childhood and often persists into adulthood. Research in the area of ADHD focuses on understanding the underlying causes of the disorder, including genetic, environmental, and neurobiological factors. This research also seeks to develop effective interventions and treatments to help individuals with ADHD manage their symptoms and improve their overall functioning. Studies have explored the effectiveness of various treatment options, such as medication, behavioral therapy, and cognitive-behavioral therapy, as well as the impact of lifestyle factors, such as diet and exercise, on ADHD symptoms. Additionally, researchers are investigating the comorbidity of ADHD with other mental health conditions, such as anxiety and depression, to better understand the complex nature of the disorder and improve treatment outcomes.
