AP PSYCHOLOGY

Detailed explanation-1: -The most common theory about the cause of schizophrenia is that there are too many dopamine receptors in certain parts of the brain, specifically the mesolimbic pathway. 1 This causes an increase in mesolimbic activity which results in delusions, hallucinations, and other psychotic symptoms.

Detailed explanation-2: -Research suggests schizophrenia may be caused by a change in the level of 2 neurotransmitters: dopamine and serotonin. Some studies indicate an imbalance between the 2 may be the basis of the problem. Others have found a change in the body’s sensitivity to the neurotransmitters is part of the cause of schizophrenia.

Detailed explanation-3: -Dopamine is an inhibitory neurotransmitter involved in the pathology of schizophrenia. The revised dopamine hypothesis states that dopamine abnormalities in the mesolimbic and prefrontal brain regions exist in schizophrenia.

Detailed explanation-4: -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.
