Interventions & Treatments
Cognitive Behavioural Therapy
Most evidence-backed optionCBT adapted for generalized anxiety.
How it works
Teaches worry postponement, cognitive restructuring, and graduated exposure to uncertainty — breaking the cycle of chronic excessive worry.
SSRI Antidepressants
Most evidence-backed optionFirst-line medication class for GAD.
How it works
Modulates serotonin signalling to dampen baseline anxiety arousal. Takes 4-6 weeks to reach therapeutic effect.
Mindfulness-Based Stress Reduction
Most evidence-backed optionStructured 8-week programme developed by Jon Kabat-Zinn.
How it works
Teaches present-moment awareness and decentering from anxious thoughts, so worry loses its grip without needing to be argued with.
