This monograph features new work on the interrelation between nutrients and brain function. The data range from findings concerned with basic mechanisms of nutrient action at the cellular level to behaviour, both normal and pathological, and psychosocial phenomena. The influence of excess and deficiency states on specific brain functions is also taken into consideration. Interdisciplinary in approach, the 19 chapters are by experts in their respective fields, and offer a representative cross-section of issues in nutrient-brain function relations. The chapters are organized into four sections, the first of which covers the effects of nutrients on basic brain processes such as protein glyconeogenesis, free radical information, and factors which control neural hyperexcitability. The following section discusses the interaction of nutrients and behavioural processes. Papers report on memory function, feeding and drinking, the phenomenon of 'brain-fag', and responses to sugars. Aspects of behaviour pathology affected by nutrient status are examined in the third section. Coverage is given to anorexia nervosa, bulimia, the premenstrual tension syndrome, affective disorders, schizophrenia, and behavioural agitation. The book concludes by considering psychosocial processes and nutrient relations. Maladaptive behaviour and delinquency are discussed. This book will be of interest to neuroscientists, nutritionists, neurologists, psychiatrists and psychologists. It offers new insights into the area of nutrient-brain function interactions, and will also serve to promote further basic and applied research.
