The ADHD Executive Functions Workbook

Written for attention deficit hyperactivity disorder (ADHD) sufferers yet useful for anyone wishing make better use of their time, this book is abundant with effective strategies for combating problems related to inattention, procrastination, disorganization, mismanagement of time, and poor planning. It begins by carefully explaining the neurologic underpinnings of ADHD and focusing on specific executive functions–the brain-based processes that assist in planning, initiating, and carrying out tasks to complete projects. Then using exercises designed to identify areas that need addressing, it aims to ‘tune up’ these executive functions for maximum productivity. In contrast to many books on ADHD, which can have good ideas but lack practical ways to apply them in everyday life, this guide includes specific recommendations for improving distractibility, working memory, attention, organization, time management, and response inhibition deficits. With strategies based in the science of how the ADHD brain processes information, this reference bridges the gap between knowledge and action.
