Schizophrenia Introduction It is necessary to take a closer look at schizophrenia because of its importance with the effects it takes with individuals, families, and even society. Each year it is estimated that 2.2 million Americans are infected with the brain disease Schizophrenia. Schizophrenia is a brutal brain disease that causes delusions, hallucinations, and paranoia. There are four types of schizophrenia; disorganized type, catatonic type, paranoid type, and undifferentiated type. What are the causes of Schizophrenia? What are the treatments? When discussing schizophrenia it is important to consider the different types of schizophrenia, the causes, and different treatments to prove that there are successful ways of managing severe symptoms of schizophrenia. Symptoms There are two groups of symptoms - positive and negative. Symptoms are divided in this way according to their impact on treatment and diagnosis (Turner, 1999). Positive symptoms are caused by normal functions superfluity or distortion. They are: Delusions. It is fallacious inflexible beliefs that appear as a result of exaggerations or distortions of reasoning and false interpretation of things taking place. For example, one can think that some book was written especially for him/her. Hallucinations. It is exaggerations or distortions of senses. The most widely distributed are auditory hallucinations, when one can hear non-existent imaginary sounds, especially voices. Disorganized speech/thinking, also described as "thought disorder" or "loosening of associations," is a key aspect of schizophrenia.
If a person has paranoid schizophrenia, he is very suspicious of others and often has great schemes of persecution at the root of the behavior, often accompanied with hallucinations and delusions. Residual schizophrenia is usually expressed through person's having no motivation or interest in everyday life. People who have schizoaffective disorder have symptoms of schizophrenia as well as mood disorder such as major depression, bipolar mania, or mixed mania. Undifferentiated schizophrenia requires the general diagnostic criteria for schizophrenia but not conforming to any of the above types, or exhibiting the features of more than one of them without a clear predominance of a particular set of diagnostic characteristics. Causes and effects There are many factors that may cause schizophrenia and the scientists are still working on trying to identify all the ones. But the cost common of them are genetic and environmental. Genetic cause of schizophrenia usually lies in person's having immediate relatives with a history of this or other psychiatric diseases (for example, schizoaffective disorder, bipolar disorder, depression, etc). Some researchers estimate schizophrenia to be highly heritable (some estimates are as high as 70%). However, genetic evidence for the role of the environment comes from the observation that one identical twin does not universally develop schizophrenia if the other one does. A recent review of the genetic evidence has suggested a 28% chance of one identical twin developing schizophrenia if the other already has it.
People frequently have to try more than one drug to partially or completely control the positive symptoms - hallucinations, delusions, paranoia, racing thoughts, etc. They are not as effective in controlling negative symptoms, and may cause side-effects of their own. However, second-generation antipsychotics have shown more success with some patients in treating negative and cognitive symptoms. Summary Schizophrenia is a severe mental disorder characterized by impairments in cognition, affect, and behavior. Patients usually experience persistent delusions, hallucinations, and emotional withdrawal. The symptoms of the disease may be controlled with medication which varies in price and individual effectiveness, and through cognitive therapy intervention Though schizophrenia has little effect on certain attention-related tasks, it has a large effect on others - everything depends on the task being performed. Today, schizophrenia has an incidence rate of one per ten thousand people per year and a lifetime prevalence rate of 1 percent (L.C Johns & J. van Os, 2001). The age of onset ranges from late teens to mid-thirties, and there are gender differences: for men, the age of onset is early to mid-twenties. Women tend to have an age of onset in the late twenties and are more likely to exhibit more mood symptoms and have a better prognosis; yet, they also have a greater chance of being misdiagnosed. 60 to 70 percent of individuals diagnosed with the schizophrenia never marry, and about 10 percent end their life in suicide.
