Neuroleptics are drugs that are typically used to treat psychotic disorders, such as schizophrenia.
Individuals with psychotic disorders have usually lost touch with reality, and they have difficulty distinguishing what is real from what is not.
They may be suffering from hallucinations, a perceptual experience that only they can see, hear, smell, taste, or feel, or delusions, which are, according to the DSM-IV-TR (2000), “erroneous beliefs that usually involve a misinterpretation of perceptions or experiences.”
People with delusions may believe that they are being followed or that certain signs are directed only at them, such as believing a roadside ad for a dating service to be a coded message for their eyes only.
There are times when someone with OCD has difficulty distinguishing what is real from what is not, the obsessions take on a delusional quality, and that may call for the prescription of these types of drugs.
Neuroleptics affect the neurotransmitter dopamine, either blocking its release or affecting its ability to transmit messages to other neurons.
