Positive psychology—the study and promotion of character strengths, positive emotion, optimism, and resilience—has gained considerable momentum and support over the last 20 years. More recently, neuropsychology has begun to embrace related perspectives. In the first edition of Positive Neuropsychology, an extensive collection of perspectives from national leaders in neuropsychology clarified the importance of promoting cognitive health through various means. The present edition expands on the first edition, with four new chapters and updates of all previous chapters. Topics include the importance of physical, social, and intellectual engagement across the lifespan; nutrition and brain health; novel technologies used to maintain brain health and functional independence; compensating for and preventing cognitive limitations; and strategies to promote brain health in clinical and other settings. Chapters reveal not only the benefits of understanding cognitive health and optimal outcomes across the lifespan, but also emerging avenues for practitioners to expand their work into non-traditional settings. Bringing new dimensions to the neuroscience, wellness, and positive psychology literatures, Positive Neuropsychology will interest a wide range of academics and clinicians, including neuropsychologists, clinical and health psychologists, geriatricians, primary care physicians, cognitive neuroscientists, and other healthcare professionals.
