The science behind depression
Depression affects the brain’s chemistry and function. It’s linked to imbalances in neurotransmitters – chemicals like serotonin and dopamine that help regulate mood. When these chemicals are out of balance, it can impact emotions, motivation and even physical energy levels. Brain scans show that depression can also change how different parts of the brain communicate, particularly areas linked to stress and emotional regulation.
Depression isn’t caused by just one thing. It can develop from a mix of biological, psychological and social factors. Some people may be more genetically vulnerable to depression, while for others, life experiences play a bigger role.
