🫀 โรควิตกกังวลทั่วไป

Is โรควิตกกังวลทั่วไป a normal emotion or does it require treatment?

Anxiety itself is a normal adaptive emotion that serves a protective function at low to moderate intensity. Treatment is warranted when anxiety intensity, frequency, or duration markedly exceeds the triggering context and causes significant distress or functional impairment—such as avoiding social situations or inability to work.

Which works better: anti-anxiety medication or CBT?

Research shows combined treatment yields optimal outcomes. SSRIs (e.g., sertraline, paroxetine) effectively reduce baseline anxiety levels, while CBT provides long-term coping skills and relapse prevention. Relapse rates after medication-only treatment are approximately 40-60%, significantly higher than patients who received CBT.

Why does deep breathing help with anxiety?

Anxiety activates the sympathetic nervous system (fight-or-flight), accelerating heart rate and shallow breathing. Deep diaphragmatic breathing—especially prolonged exhalation—stimulates the vagus nerve, triggering the parasympathetic system (rest-and-digest), lowering heart rate and blood pressure, and interrupting the physiological feedback loop of anxiety.

Does exposure therapy make anxiety worse?

Short-term discomfort may increase, but long-term outcomes are well-established. The key is the graded approach—starting with low-anxiety situations. Research confirms 80-90% of anxiety disorder patients show significant improvement after completing exposure therapy. Properly conducted, exposure enables safety learning: the feared outcome doesn't occur.

What's the difference between mindfulness and CBT?

CBT targets thought content—identifying and modifying distorted cognitions. Mindfulness cultivates a new relationship with thoughts and emotions—not changing content but transforming your attitude toward them. Modern therapy increasingly integrates both: CBT for cognitive flexibility, mindfulness for emotional acceptance.

Where is the boundary between โรควิตกกังวลทั่วไป and normal worry?

The boundary lies in three dimensions: controllability, intensity, and functional impairment. Normal worry is controllable—you can set it aside when needed. GAD worry is uncontrollable—it persists like background noise. Normal worry has clear real triggers; GAD often involves "what if..." scenarios about low-probability events. Functional impairment is the ultimate criterion—if worry prevents concentration, disrupts sleep, causes persistent muscle tension, and affects work or life, treatment is indicated.

What is different about the brains of โรควิตกกังวลทั่วไป patients?

Neuroimaging studies show GAD patients have elevated baseline amygdala (threat detection center) activity, while prefrontal cortex (top-down emotion regulation center) efficiency in regulating the amygdala is reduced. This means the brain's "alarm system" is oversensitive while the "calming system" has diminished capacity to suppress the alarm. The good news: both CBT and SSRIs effectively change these neural circuit functional connections.

Why are โรควิตกกังวลทั่วไป patients particularly sensitive to uncertainty?

The core cognitive feature of GAD is "intolerance of uncertainty"—inability to tolerate ambiguous "maybe yes, maybe no" states. The brain attempts to gain control by "over-worrying" to exhaust all possible scenarios. This strategy seems superficially useful ("I'm prepared for the worst") but consumes enormous psychological resources. Treatment focuses on distinguishing controllable from uncontrollable worries—taking action only on the former.
