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 30. Men tend to experience symptoms a little earlier than women. Most of the time, people do not get schizophrenia after age 45.Schizophrenia rarely occurs in children, but awareness of childhood-onset schizophrenia is increasing" (Schizophrenia, 2012, NIMH: 2). The disease is fairly rare "about 1% of Americans have this illness," but it is so debilitating the illness warrants further research and attention (Schizophrenia, 2012, NIMH: 2). While symptoms vary with every person, some of the most common include auditory hallucinations and disordered thinking. Movement disorders such as catatonia have also been noted and a 'negative effect' or an inability to respond normally to stimuli as well as the 'positive effect' of responding to stimuli others do not recognize (Schizophrenia, 2012, NIMH: 2).
Another important reason for further research on the topic is the fact that the causation of schizophrenia remains unclear. Genetics seems to play a key component in the development of the disorder. Although it only occurs in 1% of the population, schizophrenia occurs in 10% of persons "who have a first-degree relative with the disorder, such as a parent, brother, or sister" and even having second-degree relatives or distant relatives with schizophrenia significantly increase the likelihood of developing the disorder. "The risk is highest for an identical twin of a person with schizophrenia. He or she has a 40 to 65% chance of developing the disorder" (Schizophrenia, 2012, NIMH: 6).
Yet this raises an intriguing question -- although genetics has a significant impact upon the likelihood of developing the disorder, even in the cases of identical twins not EVERY set of identical twins, raised together, becomes schizophrenic. Environment must play some role in the manifestation of schizophrenia, although the precise impact is unclear. This statistic points to the fact that schizophrenia is caused by multiple environmental factors. "Studies of brain tissue after death also have revealed differences in the brains of people with schizophrenia. Scientists found small changes in the distribution or characteristics of brain cells that likely occurred before birth" but it is uncertain that these brain changes are the result of the illness, or a precursor of the ailment (Schizophrenia, 2012, NIMH: 6).
As well as its complex causation, another motivating factor to study schizophrenia is the fact that treating schizophrenia can be so stubborn and so difficult. The severe and debilitating side effects of the original antipsychotics such as Thorazine and Haldol used to treat schizophrenia led many sufferers to not to take their medications. These antipsychotics caused tardiac dysconesia (Parkinson's disease-like tics) which did not abate even when the medications were discontinued. Another medication called clozapine was developed in the 1990s which did not cause as many symptoms but "can sometimes cause a serious problem called agranulocytosis, which is a loss of the white blood cells that help a person fight infection. People who take clozapine must get their white blood cell counts checked every week or two. This problem and the cost of blood tests make treatment with clozapine difficult for many people" (Schizophrenia, 2012, NIMH: 6: 7). More recent atypical antipsychotics such as Risperdal "can cause major weight gain and changes in a person's metabolism. This may increase a person's risk of getting diabetes and high cholesterol. A person's weight, glucose levels, and lipid levels should be monitored regularly by a doctor while taking an atypical antipsychotic medication" (Schizophrenia, 2012, NIMH: 6: 7).
Cognitive behavioral therapy is often used in conjunction with drug treatments to help schizophrenics 'not listen' to their voices and to teach them psychological coping mechanism to deal with their illness. Other forms of therapy include occupational 'life skills' therapy and group therapy. Still, despite the available psychopharmacological treatments, life expectancies of persons with schizophrenia are 12 to 15 years less than the average person (Saha, Chant, & McGrath, 2007). Whether this is due to a higher suicide rate or side effects of medication remains unclear and further research is being conducted on the subject, some of which has apparently contradictory conclusions (Saha, Chant, & McGrath, 2007). Other factors that may contribute to morbidity lie in the fact that schizophrenics are more likely to be socially isolated than their non-schizophrenic peers and to suffer problems like homelessness (Saha, Chant, & McGrath, 2007).
