In the article, Biological Investigations in Indian Psychiatry, the author discusses the results of tests that were conducted on Indian subjects who suffer from mental illnesses such as bipolar disorder, schizophrenia, and anxiety disorders. The research being conducted, using a variety of tests was intended to determine any trends that may be contributing factors to a decline in the mental health of the population of India.
The article uses nominal scales to group the subjects who are participating in the research on schizophrenia. For example, those that are included in the schizophrenia research are grouped into categories such as those with chronic schizophrenia, acute schizophrenia and control subjects. This research was centered on specific proteins and the disease and determined that only chronic patients showed a slight elevation in protein levels. Another study went a step farther and grouped subjects by age, sex and whether or not they had schizophrenia and used these nominal groups to determine if prolactin values had an effect on the disease. This study concluded that prolactin values are not a reliable indicator that someone may or may not be susceptible to schizophrenia.
The bipolar research studies focus on a lithium serum and how it affects those with the bipolar disorder. These tests also use nominal grouping of the subjects and uses control samples as a baseline for the experiments. The researchers note the importance of maintaining a control sample to base test results on and discuss the varying timeframes for which a sample will remain useable with no adverse affects on the testing. Over a period of three months, subjects had various chemical levels monitored with the use of the lithium serum. At the end of the three month period the researchers determined that the results were not helpful in their studies.
In another study, patients with epilepsy who... [continues]
