There appears to be a tendency for schizophrenia to run in families. This suggests that genes play a role. Gottesman found that schizophrenia is more common among biological relatives of a person with schizophrenia and also that the closer the degree of genetic relatedness, the greater the risk. Gottesman conducted family studies and showed that when both parent are schizophrenic the children have a 46% concordance rate, however, if only one parent had it, it dropped to 16% and dropped to a further 1% when the sibling of the child had schizophrenia. This suggests that a genetic factor is involved.
This screening is basically for confirmation purposes. There was a study conducted (from Oct. 2002 – Aug. 2005) where 619, 105 infants were screened for cystic fibrosis. Of those screened 3,797 were positive, 128 were diagnosed with cystic fibrosis, and 690 cases were “not closed”. For the patients that participated in this study sweat tests were also administered. Sweat chloride level for most patients with cystic fibrosis is greater than 60 mmol/l, but there is a possibility for a newborn under three months to have a borderline sweat chloride.
It is 50% for identical twins. Studies have shown the development of Schizophrenia among adopted relatives and twins who lived apart from each other. On, the other hand, there are family members of Schizophrenic patients who did not develop Schizophrenia. Further more, there are some individuals who developed Schizophrenia without a genetic history of Schizophrenia. However, some of these later groups were born by fathers who are older that 60 years.
A family study conducted by Gottesman reported that the rate of schizophrenia in the general population is 1% whereas the rate in people where both parents suffer in 46%. He also found that if one parent suffered the rate was 13%. Gottesman concluded that the closer the bloodline the higher the risk. He and Shields then conducted a study on the concordance rates of schizophrenia in 40 sets of twins. They found that in dizygotic twins the rate
Essay Plan Biological Explanations of Schizophrenia 1. Describe in some detail the genetic factors- family studies- Gottesman found that schizophrenia is more common among biological relatives of a person with schizophrenia and also that the closer the degree of genetic relatedness, the greater the risk. For instance, children with 2 schizophrenic parents have a concordance rate of 46%, children of one schizophrenic parent 13% and siblings 9%. Although this could be due to common rearing patterns or other factors not relating to heredity. Twin studies- Joseph calculated concordance rates of 40.4% for MZ twins and 7.4% for DZ twins.
Is there an Autism epidemic? Problem Autism is a pervasive developmental disorder that affects social and communication skills and in some cases, to a lesser degree, motor and language skills. (6) Autism was first diagnosed in the 1940’s and was described as a very rare disorder with cases being as few as one in every 10 000 children (1). By the1990’s diagnoses began to soar (as shown in graph below) and diagnosis had risen to one in every 500 children. In the 1990’s it was speculated that the increase was due to certain chemicals in vaccinations such as the MMR.
I was surprised to see that 21 people believed that 0 to 18 was when people were diagnosed. And 5% believed that you weren’t diagnosed with the disorder until you were over 40. This new information leads me to believe that most people thought that you develop bipolar disorder at a young age. The final question I asked was if bipolar disorder is a serious problem. I was shocked to see that two actual people put no for that question when it is so obvious that bipolar disorder is a serious issue.
1.5 million people will be diagnosed with schizophrenia this year alone and, consequently, 10% of those will commit suicide. Schizophrenia is most likely to occur between the ages of 17-35 years, with the onset earlier in men than women. 8-13% of all schizophrenics are linked to cannabis use
PARANOID SCHIZOPHRENIA Paranoid Schizophrenia is a chronic mental illness in which reality is distorted, also known as psychosis; people with Paranoid Schizophrenia cannot tell what is real from what is imagined. Paranoid Schizophrenia is one of the most common diagnosed forms of Schizophrenia; it only affects 1% of the general population, about 2.2 million people. People diagnosed with schizophrenia make up about half of all patients in psychiatric hospitals and may occupy as many as one quarter of the world's hospital beds. People with schizophrenia have problems remembering, paying attention, and communication .Some researchers believe Paranoid Schizophrenia develops as a young child, but major symptoms do not affect the mind fully until
Schizophrenia is a mental illness that most often requires multiple therapies that help a person manage their mental disease. For the larger portion of individuals with schizophrenia a combination of psychotropic medication and a psychosocial therapy is most successful (Townsend, 2008). Schizophrenia has been reviewed and presented in steps for nursing to help diagnose people. The cause of the mental disease remains a puzzle to psychiatrists, but identifying the type and care needed for people is clear. Schizophrenia can be managed, but it requires the assistance of medication and possibly other therapies.
