My psychiatrist told me I have high dopamine in some brain parts and in others low dopamine. I wonder why he said that but I found this online.
"Having low levels of dopamine can make you less motivated and excited about things. It’s linked to some mental illnesses including depression, schizophrenia and psychosis.
Having too much dopamine — or too much dopamine concentrated in some parts of the brain and not enough in other parts — is linked to being more competitive, aggressive and having poor impulse control. It can lead to conditions that include ADHD, binge eating, addiction and gambling."
