If it's true that we live in an age of anxiety, says Restak, a neuropsychiatrist and professor at George Washington University Medical Center, then our best defense is to learn as much as we can about anxiety and what causes it. Restak (
Mozart's Brain and the Fighter Pilot) examines anxiety from both a cultural and physiological point of view. Unlike fear, which is based on a real, external threat, anxiety is an emotion of tension or dread originating from within. Restak details research conducted with animals and, in some cases, humans that reveals the workings of various brain parts involved in the creation of anxious feelings. The amygdalae (two small structures on either side of the brain), for example, receive and evaluate signals that trigger hormonal and chemical responses. In our age of information overload, overstimulated amygdalae can lead to overproduction of anxiety. Restak believes some anxiety is necessary—studies show that people with certain kinds of brain damage have no anxiety and act impulsively and self-destructively. But excessive anxiety can spark phobias, panic attacks and other anxiety disorders. Although this is not a self-help guide, the author does suggest strategies for relieving anxiety, such as avoiding TV hype and instead seeking solid information about anxiety-arousing events.

Restak has written extensively about the brain and mental health, and in this brisk volume, he addresses anxiety. Explicating this vague but palpable emotion, Restak differentiates it from its kindred feeling of fear, which is intense but transitory, whereas anxiety asserts a more diffuse but continual presence in the mind. Restak illustrates anxiety both with social examples (such as dread of a terrorist attack) and individual cases from his medical practice. Making the point that it has effects both beneficial (alerting a person to genuinely dangerous situations) and incapacitating (fretting about catastrophic but statistically improbable situations), Restak exudes empathy with instances of his personal experiences. That style will engage readers throughout as he explores significant experiments in neuroscience on anxiety; several clinical diagnoses, such as obsessive-compulsive disorder; and various medications commonly prescribed for anxiety. On the other side of the anxiety coin, Restak discusses risk-taking folks who intentionally court anxiety. For general readers, Restak dispels worry about worry and tenders sensible strategies for quelling it.
