F40-F48: Neurotic, stress-related and somatoform disorders

F41: Other anxiety disorders

Other anxiety disorders, as classified under the ICD-10 F41 code range, comprise various conditions marked by excessive and persistent unease or fear. The root of these conditions typically lies in a complex interaction of genetic predisposition, environmental influences, and biochemical imbalances in the brain. Individuals afflicted may experience rapid heart rate, sweating, trembling, restlessness, tiredness, and difficulty concentrating. Typically, this group of disorders evolves into long-term conditions if not addressed appropriately. Different types of anxiety disorders may present differently, with certain disorders triggered by specific situations or objects, while others feature a more pervasive and persistent nature of anxiety. These conditions majorly affect the nervous system and manifest psychologically, but can also cause physical symptoms due to the body's response to sustained stress. It is noteworthy to mention that while fear is an appropriate response to a threat, anxiety disorders are characterized by fear or distress that is out of proportion to any actual danger.
