This book compiles a series of educational and thought-provoking chapters from the world's leading cognitive and clinical scientists to describe the latest research on cognitive impairments in a host of pathological conditions that affect CNS functioning, the available treatments for these impairments, and how new treatments are being tested. This volume advances the field toward the availability of cognitive enhancing drugs and devices that will benefit those who need them most and others who may believe that these techniques can help them to thrive. Psychological science and cognitive neuroscience have become the most popular endeavor of students worldwide, are the focus of attention of our greatest scientific accomplishments, and are the emphasis of many publications in the mainstream media. Because humans depend on cognitive abilities for survival, quality of life, and productivity, improving them has never been more important. Those with impairments in key aspects of cognition suffer dearly because they are unable to obtain and retain information, unable to make sound decisions based on the information at hand, and unable to plan future activities. The availability of pharmacological and behavioral interventions that can improve cognitive abilities and provide impaired individuals with the social, occupational, and functional quality of life that the rest of us enjoy has potential far-reaching implications. Such interventions can also benefit those who want to boost current cognitive abilities to higher levels, perhaps as a means to hone skills in providing products for others or to gain an edge on competition.
