Your children might or might not get schizophrenia if your sister and mother have it. There is no guarantee either way.
No. Hallucinations are one of the many symptoms of schizophrenia.
Population statistics on the heredity of schizophrenia estimate that a child with one diagnosed parent has about a 10% genetic risk of developing the disease themselves (this is compared to a 1% risk in the general population). The risk goes up significantly if both parents (60%), a grandparent, or other close relatives also have schizophrenia.
About 2.2 million Americans have schizophrenia.
Approximately 285 000 people in Australia have schizophrenia.
The course of schizophrenia in adults can be divided into three phases or stages.
Yes. Although most people with schizophrenia have other health conditions, especially substance abuse disorder, many only have schizophrenia.
Many people with schizophrenia do have trouble sleeping. One study suggested that 44% of people with schizophrenia meet the diagnostic criteria for insomnia.
There is no one gene for schizophrenia. However, there are many different genes that may contribute to schizophrenia. A gene on chromosome 1 in the 22 family is implicated in schizophrenia, as well as genes on chromosomes 11 and 6.
Schizophrenia reduces life expectancy by 12 to 15 years.
A brain scan cannot detect schizophrenia, although many people with schizophrenia do have abnormal brain scans. The brain damage is not apparent until the disease has already progressed far enough to show clear signs of schizophrenia.
Depending on how you divide it, there are either 5 or 2 types of schizophrenia. The five types are paranoid, disorganized, residual, catatonic, and undifferentiated. The two types are positive (or Type I) schizophrenia and negative (or Type II) schizophrenia. Positive schizophrenia consists of mainly positive symptoms. Negative schizophrenia consists of mainly negative symptoms.
