General Anxiety Disorder

Generalized Anxiety Disorder (GAD) is characterized by excessive, uncontrollable worry about various aspects of daily life. Neurobiologically, GAD is associated with dysregulation in the brain's fear-response systems, particularly within the amygdala and hippocampus. Functional imaging studies have revealed reduced resting-state functional connectivity between the amygdala and prefrontal cortex in individuals with GAD, indicating impaired regulation of emotional responses. Additionally, structural MRI evidence suggests deficits in selective brain regions, including the anterior cingulate cortex, which plays a role in emotional processing and regulation.

In the United Kingdom, GAD is a prevalent mental health condition. Data suggests that approximately 6 in 100 people are diagnosed with GAD in any given week in England. Furthermore, a survey in 2007 estimated the prevalence of GAD among adults in England to be 4.4%. These statistics highlight the significant impact of GAD on the UK population, emphasizing the need for effective identification and treatment strategies to address this widespread disorder.
