The brain relies on a delicate balance of chemical messengers called neurotransmitters to regulate mood, anxiety, and cognitive function. Key neurotransmitters include serotonin (mood regulation), dopamine (motivation and reward), and GABA (anxiety reduction).
When these systems become dysregulated, symptoms of anxiety and depression can emerge. Chronic stress can deplete neurotransmitter reserves, while genetic factors may influence how efficiently your brain produces and processes these chemicals.
This biological foundation explains why mental health conditions are medical issues requiring appropriate treatment, not simply matters of willpower or attitude.
