Anxiety is a normal human emotion. It’s common to feel nervous before a big presentation, a job interview, or while waiting for important news. In fact, a certain level of anxiety can boost focus and performance in everyday situations.
An anxiety disorder, however, goes beyond typical worry. When anxious feelings become frequent, intense, or difficult to manage, they can interfere with daily routines and overall well‑being.
The National Institute of Mental Health estimates that anxiety disorders affect about 40 million U.S. adults each year, though many do not seek treatment.
There are several types of anxiety disorders, including:
- Panic disorder
- Posttraumatic stress disorder (PTSD)
- Phobias
- Generalized anxiety disorder (GAD)
- Obsessive‑compulsive disorder (OCD)
Some individuals may also experience agoraphobia, which involves avoiding certain places or situations due to fear of a panic episode.
