PsycheGuard AI: An Intelligent Platform for Early Detection of Mental Health Disorders Through Multimodal Emotion Analysis

Abstract: Depression, anxiety, and chronic stress are now widespread, yet timely diagnosis remains difficult to achieve at scale. A shortage of trained clinicians, the stigma still attached to seeking help, and the absence of any ongoing, objective way to track a person's psychological state all contribute to delayed care and poorer long-term outcomes. Most current mental-health apps rely on static questionnaires or basic sentiment scoring, neither of which captures the nuance needed to flag a developing problem early or tailor support to the individual. PsycheGuard AI is put forward here as a web-based monitoring system that draws on machine learning and natural language processing to close this gap. It reads a user's written and spoken input, behavioral cues, and standard screening results to surface early indicators of depression, anxiety, and stress, then translates that analysis into a running risk level, a mood trend over time, and tailored recommendations, with alerts raised when intervention appears warranted. The implementation uses Python and Django on the backend, a Bootstrap-based front end, and Scikit-learn together with NLTK/spaCy for the modelling layer, backed by SQLite/MySQL for storage and Matplotlib/Plotly for visual reporting. Testing shows the combined system outperforms single-method screening approaches while sustaining continuous mood tracking and dependable emotion classification. Authentication, encryption at rest, and role-based permissions protect user data throughout. Because the architecture stays computationally light, the platform is realistic to deploy at scale in settings such as universities and workplaces.
