Dopaminergic therapy increases dopamine levels, helping improve motor symptoms in patients with Parkinson’s disease. However, increasing dopamine levels can also cause chemical and physical changes in the brain that inadvertently lead to symptoms such as hallucinations or delusions.
Is dopamine a hallucination?
Those with hallucinations and other psychotic symptoms are known to have elevated dopamine, the main area of focus for available treatments for psychosis, but it was unclear how this could lead to hallucinations.
Can dopamine cause psychosis?
Scientists have long known that dopamine is involved in the development of schizophrenia and other psychotic disorders. People with schizophrenia have an overactive dopamine system, releasing more dopamine than healthily people.
Can a chemical imbalance cause hallucinations?
Fact: Individuals may “hear voices” but these are auditory hallucinations due to chemical imbalance, not multiple personalities. Fact: They are often withdrawn and are no more dangerous than anyone else.
What happens if dopamine levels are too high?
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.
What is the difference between dopamine and serotonin?

The typical course of the initial psychotic episode can be conceptualised as occurring in three phases. These are the prodromal phase, the acute phase and the recovery phase.
What happens to dopamine in psychosis?
In the case of schizophrenia, the dopamine hypothesis proposes that dopamine transmission is overactive in the mesolimbic areas and underactive in the prefrontal cortex. Dopamine dysregulation is also seen in the amygdala, which is involved in emotional processing.
Does psychosis damage the brain?
Longer duration of untreated psychosis was associated with accelerated hippocampal atrophy during initial antipsychotic treatment of first-episode schizophrenia, suggesting that psychosis may have persistent, negative effects on brain structure, according to finding published in JAMA Psychiatry.
