Anxiety affects millions, manifesting as generalized anxiety disorder GADobsessive compulsive disorder, panic disorder, phobias, post-traumatic-stress disorder PTSDand social anxiety disorder. Not only are anxiety disorders common, but they are also crippling, frequently co-occurring and predict high risk for depressive disorders.

Shared mechanisms may explain the overlapping features of many anxiety disorders and account for associations with other highly-impairing conditions, such as major depression and substance use.

Beyond risk for specific disorders, anxiety also predicts a number of other adverse outcomes, including suicidal behavior, medical problems, social, and economic difficulties. Conversely, disorder-specific mechanisms may also exist and explain the unique features of each syndrome. Thus, it is important to understand both shared and specific aspects of anxiety.

The Primer on Anxiety Disorders provides information on diagnosis and treatment, and clinical cases are used throughout to enhance understanding of and illustrate specific disorders, comorbid conditions and clinical issues. To facilitate an integrative approach, content allows clinicians to understand patient characteristics and tailor interventions.

The integrated approach of each chapter includes recent research on genetics and neuroscience to understand the mechanisms of anxiety disorders, focusing on the forthcoming new nosology in DSM Chapters further integrate innovative advances in clinical research providing research on a range of discoveries regarding biomarkers of illness, biological predictors of treatments and the effect of treatment on neurocircuitry.

In the study, the researchers propose a new approach to mental illness that would be informed by human evolution, noting that modern psychology, and in particular its use of drugs like antidepressants, has largely failed to reduce the prevalence of mental disorders. For example, the global prevalence of major depressive disorder and anxiety disorders remained steady at 4.

According to the team, depression, anxiety, and PTSD often involve a threat of exposure to violence, which are predictable sources for these things that people call mental diseases. A large review in found that antidepressants had almost the same effect as a placebo, and their widespread use has not delivered measurable results.

Instead of addressing mental issues by their symptoms, the team proposes approaching mental illness by their probable causes. The team pointed out that there is little in our evolutionary history that accounts for children sitting at desks quietly while watching a teacher do math equations at a board.

Other disorders such as depression, anxiety, and PTSD are not hereditary, occur at any age, and are often tied to threatening experiences. The team proposes they may be responses to adversity and serve as signals, much like physical pain does, to make people aware of the need for help. These conditions also disproportionately affect people in developing countries.

Does your child get much more excited or much more irritable than other kids? Do you notice that your child goes through cycles of extreme highs and lows more often than other children? Do these mood changes affect how your child acts at school or at home?

Some children and teens with these symptoms may have bipolar disordera brain disorder that causes unusual shifts in mood, energy, activity levels, and day-to-day functioning. Bipolar disorder is a mental disorder that causes people to experience noticeable, sometimes extreme, changes in mood and behavior.

Bipolar disorder, which used to be called manic-depressive illness or manic depression, is not the same as the normal ups and downs every child goes through. The mood changes in bipolar disorder are more extreme, often unprovoked, and accompanied by changes in sleep, energy level, and the ability to think clearly.

With treatment, children and teens with bipolar disorder can manage their symptoms and lead successful lives. The exact causes of bipolar disorder are unknown, but several factors may contribute to the illness.

For example, researchers are beginning to uncover genetic mechanisms that are linked to bipolar disorder and other mental disorders.

However, just because one family member has bipolar disorder, it does not mean that other members of the family will have it. Many genes are involved in the disorder, and no single gene causes it. Research also suggests that adversity, trauma, and stressful life events may increase the chances of developing bipolar disorder in people with a genetic risk of having the illness. Some research studies have found differences in brain structure and function between people who have bipolar disorder and those who do not.

Researchers are studying the disorder to learn more about its causes and effective treatments. Mood episodes in bipolar disorder include intense emotions along with significant changes in sleep habits, activity levels, thoughts, or behaviors. A mixed episode has both manic and depressive symptoms. These mood episodes cause symptoms that often last for several days or weeks.
