I am thankful to Dr. Petrie that he focused on the unique catecholaminergic activity enhancer (CAE) effect of (-)-deprenyl, which is unrelated to MAO-B inhibition and explains why an enhancer substance, like (-)-deprenyl, improves cognition, attention, memory and reaction times, and brings about subjective feeling of increased vitality and energy.

Since, to motivate clinicians to think over this new line of (-)-deprenyl research was my main aim when writing this book, I am especially pleased with Dr. Petrie's opinion: "For those of us interested in treatment options in geriatric health and disease, the drug deserves serious reevaluation."
