Anxiety is a psychological and physiological state characterized by feelings of fear, worry, and nervousness. It is a normal response to stress or perceived threats, but can become problematic when it is excessive or persistent. Anxiety disorders are a group of mental health conditions that involve excessive levels of anxiety and related symptoms, such as panic attacks, phobias, and obsessive-compulsive behaviors. Research in the area of anxiety focuses on understanding the causes, symptoms, and treatments of anxiety disorders, as well as developing effective interventions to help individuals manage and reduce their anxiety levels. This research often involves studying the underlying neurobiological mechanisms of anxiety, identifying risk factors, and exploring various therapeutic approaches, such as cognitive-behavioral therapy and medication.
