Summary

• Generalized Anxiety Disorder (GAD) is a mental health condition characterized by excessive, uncontrollable worry and anxiety about a variety of topics, events, or activities. This anxiety is often disproportionate to the circumstances and persists over a long period, making daily life challenging.

Diagnosis

• Medications: Antidepressants (e.g., SSRIs or SNRIs) or anti-anxiety medications (e.g., benzodiazepines) can help reduce symptoms.
• Lifestyle Modifications: Including regular exercise, stress management techniques, and relaxation strategies.
