A Short Note on Generalized Anxiety Disorder

Justin Ejike

Anxiety can cause physical and cognitive symptoms such as restlessness, irritability, easy fatiguability, difficulty concentrating, increased heart rate, chest pain, abdominal pain, and a variety of other symptoms that may vary depending on the individual. Anxiety disorders are a cluster of mental disorders characterized by significant and uncontrollable feelings of anxiety and fear. In casual discourse, the terms anxiety and fear are frequently used interchangeably. They have distinct meanings in clinical use: The umbrella term “anxiety disorder” refers to a number of specific disorders that include fears (phobias) or anxiety symptoms. There are several types of anxiety disorders, including generalized anxiety disorder, illness anxiety disorder, specific phobia, social anxiety disorder, separation anxiety disorder, agoraphobia, panic disorder, and selective autism.
