neurobiology of mental illness

The neurobiology of mental illness involves changes in the brain's structure and function that can affect emotions, thoughts, and behaviors. Neurotransmitters, which are chemicals that transmit signals between nerve cells, play a key role; imbalances in these chemicals, such as serotonin and dopamine, can lead to conditions like depression and anxiety. Additionally, factors such as genetics, environment, and stress can influence how the brain develops and functions, contributing to mental health disorders. Understanding these biological aspects helps in developing effective treatments and therapies to support mental well-being.
