Mental health disorders are a growing concern worldwide, with approximately one in four individuals experiencing a mental health issue each year. Traditional treatments often rely on medication and therapy, but these approaches can be invasive, expensive, and ineffective for some individuals. Recently, neurofeedback has emerged as a promising non-invasive technique for managing mental health. Here, we propose a novel neurofeedback integrated wearable system designed to monitor and regulate brain activity in real-time, providing individuals with a personalized and adaptive tool for managing their mental well-being. Our system utilizes electroencephalography (EEG) to record brain activity, which is then processed using machine learning algorithms to provide real-time feedback to the user.
