Explanation:
Anxiety disorders are characterized by significant worry and tension that are persistent and very hard to control. These disorders manifest through physical symptoms like rapid heartbeat, sweating, trembling, dizziness, and mental symptoms such as worry, stress, and nervousness. This chronic worry often interferes with daily functioning, as individuals anticipate disaster and are overly concerned about health, money, family, work, or other crucial aspects of life. The exact cause is believed to be a combination of genetic and environmental factors, including brain chemistry, life experiences, and learned behavior.
