This book is crammed with puzzles designed to stimulate each of your brain's cognitive functions, keeping it strong and fit. Many different types of puzzles are included, and each of the five levels increases the challenge of solving them. Includes three self-evaluations that allow you to assess your improvement in areas such as focus, attention, memory, and more. With these puzzles, exercising your brain can be fun! The consultant is Dr. Elkhorn Goldberg, a Ph.D. neuropsychologist who created the Manhattan-based Cognitive Enhancement Program, a fitness center for the brain and who wrote The Executive Brain: Frontal Lobes and the Civilized Mind; and The Wisdom Paradox: How Your Mind Can Grow Stronger as Your Brain Grows Older.
