Generalized Anxiety Disorder (GAD) is a chronic mental health condition characterised by excessive and uncontrollable worry or fear about a range of topics, from everyday life challenges to long-term concerns about health, family, or work. Individuals with GAD often find it difficult to control their anxiety, even when there is little or no reason to be anxious. The condition can significantly impair daily activities, social interactions, and overall quality of life.
GAD is one of the most common anxiety disorders globally, affecting around 3-5% of the population. It is more prevalent in women than in men, and it typically begins in childhood or adolescence, though it can develop in adulthood as well. Symptoms of GAD include constant worry, restlessness, fatigue, difficulty concentrating, irritability, muscle tension, and sleep disturbances. When left untreated, GAD can lead to other mental health issues, such as depression, and can significantly reduce an individual’s quality of life.
Fortunately, over the past few decades, the treatment landscape for GAD has evolved, with significant advancements in both pharmacological and psychotherapeutic options. This has led to increased opportunities for improving the management of the disorder, contributing to the growing market for GAD treatment.
