Background: Charaka identifies Prajnaparadha, the “offence against wisdom”, as one of the three root causes of all disease. It is defined as the impairment of intellect (Dhi), restraint (Dhriti) and memory (Smriti), leading a person to act in ways they know to be harmful. Lifestyle psychiatry has recently shown that modifiable behaviours, including physical activity, diet, sleep and smoking, influence the onset and course of mental disorders. Objective: To describe the classical concept of Prajnaparadha, map it to modern psychological constructs of decision-making and self-regulation, and examine its relevance to the prevention and management of mental and lifestyle disorders. Methods: Narrative review of Charaka Samhita and selected modern literature on behavioural risk factors, lifestyle psychiatry, habit formation and health behaviour change. Results: Prajnaparadha includes errors of the intellect, failure of restraint and loss of memory, expressed through improper actions of body, speech and mind. These map closely onto modern concepts of impaired judgement, poor self-control and forgetting of learned consequences. Behavioural risk factors account for a large share of global disease burden, and meta-reviews show that physical activity, diet quality, sleep and smoking cessation affect mental health outcomes. Classical remedies, including Sadvritta, Achara Rasayana, Dinacharya and Sattvavajaya, correspond to modern strategies of habit change, self-monitoring and psychological therapy. Conclusion: Prajnaparadha provides a coherent Ayurvedic model of behaviour-driven disease that is compatible with lifestyle psychiatry. It can inform the design of preventive and therapeutic programmes, provided its components are operationalised and tested.
