Although antipsychotics were originally intended to treat psychosis, some antipsychotic medications may also be used to treat:
- Severe anxiety
- Severe depression
- Psychotic symptoms of depression
Similar to antidepressants, antipsychotic medications focus on altering brain chemistry. Newer antipsychotic medications treat depression by altering serotonin signaling, the same neurotransmitter impacted by typical antidepressants.
All antipsychotic medications also alter dopamine signaling in different parts of your brain. Like serotonin, dopamine is another one of the neurotransmitters present in the brain.
Dopamine carries messages from one part of the brain to another and impacts various activities in your body, including:
- Pleasurable reward and motivation
- Behavior and cognition
- Sleep and arousal
