This view has one advantage in that it goes toward explaining why the same general disease - schizophrenia - can vary significantly from person to person. The Vulnerability Model suggests to us that schizophrenia is caused by a combination of interacting factors including physical, psychological and environmental events that work dysfunctionally together to produce what we call "schizophrenia."
This does not mean the brains of schizophrenics are identical to those without schizophrenia, however. Some evidence persuasively points to brain development that goes wrong before a baby is ever born. During gestation, brain cells have to migrate from one central location to become the different parts of the brain. In the process, some brain cells are redundant, and the brain "prunes," or destroys them. Some researchers believe that in some people who later develop schizophrenia, brain cells group together that should not be together, resulting in a baby that is born with a dysfunctional brain from the beginning (Bower, 1996).
Research suggests that fetal development of the brain malfunctions about halfway through the pregnancy, when large numbers of neurons are traveling to the place they belong in the baby's brain. Research has found disorganized clumps of neurons both in the cerebral cortex and in other parts of the brain (Bower, 1996). Whether this problem is caused or worsened by...

Schizophrenia is a heterogeneous disorder and can be characterized by any of the following symptoms: intellectual deterioration, emotional blunting, disorganized speech, disorganized behavior, social isolation, delusions, and/or hallucinations (American Psychiatric Association [APA], 2000). In the current version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) schizophrenia has now been divided into five subcategories (APA, 2000). These subtypes are defined based on the presence of positive symptoms (excesses, such
Schizophrenia When people think of what it means to 'go crazy,' quite often the common image that comes to mind is that of someone with schizophrenia. Schizophrenia is a serious mental health disorder that can be physically, socially, and personally destabilizing. "Schizophrenia affects men and women equally. It occurs at similar rates in all ethnic groups around the world. Symptoms such as hallucinations and delusions usually start between ages 16 and
Schizophrenia does not really have just one single cause. It is a possibility that this disorder could be inherited but not all doctors are sure. A lot of experts suppose that schizophrenia does run in the family. Individuals that may have a close family member with the disease are more likely to advance the disorder than persons who have no kinsfolks with the disease. A lot think that might have
Much of advice to parents of schizophrenics tended to be judgmental, before the environmental and genetic factors of the illness were known: Theories blaming schizophrenogenic or emotionally withdrawn mothers are now almost totally discredited. What current research attempts to suggest is that "family and environmental stressors -- encompassing very subtle interactions common to many families -- work only in tandem with biological determinants to produce psychosis [and schizophrenia]" (McFarlane 2007).
Schizophrenia Ron Howard's 2001 film biography of the life of John Nash, A Beautiful Mind, delves into the world of a man suffering from schizophrenia. However, the film treats the disease delicately, without offering too many stereotypes or classifications of mental illness. Rather, the audience is aware that behind Nash's genius is a disturbed, albeit "beautiful" mind. Russell Crowe plays Nash, a brilliant mathematician and professor. His doctoral thesis work is
