Although it is not entirely clear how using Risperdal works for schizophrenia or other conditions, it is known that the medication blocks or lessens the effects of several chemicals in the brain. These brain chemicals (such as dopamine and serotonin) may be elevated in people with schizophrenia,
bipolar disorder (also known as
manic depression), or autism.
This medication is not a cure for bipolar disorder, autism, or schizophrenia; Risperdal only helps to control symptoms and may help prevent relapses.
