Symptoms of a schizophrenia may vary but typically include delusions, hallucinations, disorganized thinking or speaking, abnormal motor behavior or other negative cognitive behaviors, according to the Mayo Clinic. Having two or more of these symptoms for 30 days or more is typically indicative of schizophrenia, according to helpguide.org.
Many times early warning signs of schizophrenia appear before other serious symptoms. Early warning signs include social withdrawal, depression, delusions, loss of appetite or disorganized speech, according to helpguide.org. Insomnia or oversleeping, hostility or suspiciousness, depersonalization and forgetfulness, are also symptoms according to WebMD. Those who notice these early warning signs in others should continue to monitor their behavior to see if the symptoms worsen or last for a month or more.
People with schizophrenia vary wildly in their behavior and the presence of their symptoms, according to WebMD. Behavior may not be predictable and may manifest in a number of different ways. This means one of the best ways to notice the symptoms of schizophrenia is to notice changes in personality or behavior or the development of bizarre tendencies. Most individuals with this mental condition may not show any outward appearances of illness.
Childhood schizophrenia typically presents similar symptoms along with language delays, late crawling or walking or other abnormal motor behaviors such as rocking and arm flapping according to the Mayo Clinic.
