Generalized anxiety disorder (GAD) is a physiological disorder characterized by extreme anxiety caused by normal disputes that reflects in functional deterioration in the limbic system of the brain. The limbic system plays a major role in controlling and regulating fundamental emotions through neural pathways involving the amygdala, dorsolateral prefrontal cortex, ventromedial anterior complex, and hippocampus. These regions are linked to acquired anxiety and expression (Preston, 2017).

Various factors including genetics, biochemical imbalances, behavioral patterns, and life situations contribute to anxiety disorders, which are psychopathological in nature. Individuals affected by GAD typically experience excessive, unrealistic fears that interfere with their physical, emotional, and cognitive functioning (Preston, 2017). Suzy exemplifies this condition, as her traumatic childhood experiences, including parental conflicts and her mother’s overdose, contribute to her ongoing anxiety. Her symptoms manifest as intense worry, which has led her to alcoholism as a maladaptive coping mechanism.

Neurochemical imbalances are central to GAD, with neurotransmitters such as serotonin, glutamate, gamma-aminobutyric acid (GABA), cholecystokinin, and adenosine playing key roles. These neurochemicals may be either inhibitory or excitatory, modulating neural circuits involved in anxiety. Dysregulation in these systems, especially involving GABA, can lead to heightened amygdala activity and subsequent anxiety symptoms (Lichtblau, 2011).

GABA, particularly its A receptor subtype, is pivotal in controlling emotional stability. A shift in GABAergic activity towards inhibition results in sedative effects, whereas reduced GABA activity correlates with increased anxiety, restlessness, insomnia, and exaggerated reactivity (Lichtblau, 2011). Elevated amygdala activity, linked to GABA dysregulation, underpins the heightened anxiety seen in GAD.

Pharmacological treatments for GAD include benzodiazepines, gabapentin, and pregabalin. Benzodiazepines such as diazepam facilitate GABAergic inhibition by allosteric modulation of GABA-A receptors, enhancing inhibitory neurotransmission and providing rapid anxiolytic effects (National Institute of Mental Health, 2016). Gabapentin, an analog of GABA, and pregabalin increase GABA availability or efficacy, thus reducing anxiety symptoms (Lichtblau, 2011).

Suzy’s long-term use of substances like tobacco and caffeine may have exacerbated her anxiety by elevating neurochemical and receptor reactivity. Both substances can increase neural excitability, thus worsening GAD symptoms. Therefore, careful consideration of pharmacotherapy is essential, and clinicians must tailor treatments to individual needs, minimize side effects, and monitor efficacy (Preston, 2017).

In managing GAD, psychotherapy, lifestyle modifications, and medication are often combined. Cognitive-behavioral therapy (CBT) helps patients develop coping skills and challenge maladaptive thoughts. Psychoeducation about the disorder and medications fosters adherence and awareness of side effects. For Suzy, integrated treatment addressing her trauma, substance use, and anxiety is crucial for effective management and recovery.

In conclusion, GAD is a complex neuropsychiatric disorder involving neurochemical dysregulation primarily within the limbic system, especially GABAergic circuits. Pharmacological interventions aim to restore inhibitory control, thereby alleviating symptoms. Careful, personalized treatment plans are paramount, especially considering comorbid substance use and trauma history, to ensure optimal outcomes for individuals like Suzy.
