Prodromal Phase of Schizophrenia
The prodromal phase is the earliest presentation of schizophrenia; during this time, the person begins to experience distinct changes in perception or thinking, but does not display overt psychosis. Because some symptoms can be confused with typical adolescent behavior, family members or friends may not recognize this phase until after schizophrenia has been diagnosed.
Characteristic behaviors during the prodromal phase may include social withdrawal, reduced concentration or motivation, suspiciousness, peculiar speech, and an interest in abstract ideas, philosophy, the occult, or religion. The prodromal phase may last a year or more before the onset of overt psychotic symptoms. Researchers are now investigating the possible value of treatment during this phase.
The goals of the Medical Sites Network are to provide people with meaningful information to make informed decisions about their health and health care.
