Theory of biological causes of schizophrenia

Research by Meyer-Lindenberg found that reduced activity of the prefrontal cortex is linked to dopamine abnormalities. It is much less obvious, however, that there are biological changes that accompany fatherhood.

Due to these typical developments, he is unable to cope with the world around him and show normal sensory and motor responses to various stimuli.

Researchers have spent millions of hours and many hundreds of millions of dollars studying this condition. But what specific part the constitutional defects play in the development of schizophrenia is not very clear due to the paucity of researches in the area.

These conditions, however, may combine with other precipitating factors to facilitate illness onset. Due to the advances in neuroimaging and our understanding of schizophrenia, researchers can study Theory of biological causes of schizophrenia functioning brain as it carries out activities this is called functional magnetic resonance imaging.

The brains of people with the illness also tend to have less gray matter, and some areas of the brain may have less or more activity.

This interpretation receives the support of the findings of Mandell, Segal, Kuezenski and Knapp It is an accepted fact that schizophrenia is less visible in less developed nations where persons are reintegrated to their community and family more completely than they are in more highly civilized western societies.

They therefore fail to adjust with the familial and environmental conditions. Hence, they create their own social role to protect themselves from social expectations and demands.

For example, Shields, Hestow and Gottesman have been able to show that using spectrum diagnosis concordance rates for dizygotic twins as well as monozygotic twins could be elevated above the 50 per cent level.

The relationship between stress arising out of familial and social conditions and symptom development has been emphasised by Gersten, Langener, Eiserberg and Orzek So they cannot afford early treatment neither they develop the consciousness for early treatment.

In the course of discussing something else, I mentioned, for historical context, the idea that people had thought at one point that there was a clear distinction between biological and psychological problems.

Consequently, there may be irregularity in the functioning of the autonomic nervous system. His self image is destructed and is unable to develop ego defences necessary to meet anxiety provoking situations. A monozygotic identical twin of a person with schizophrenia has the highest risk — a 40 to 65 percent chance of developing the illness.

I am sure some people do. In Social Intelligence, Daniel Goleman explores an emerging new science with startling implications for our interpersonal world. In other words, the "stuff" is the same in each case call it mind, or social organism, etc.

However, different theories have been advanced to explain the aetiology of schizophrenia. But Moss views that it may be an accompanying factor among the several causes of schizophrenia. The findings of Korayni and Lehman Luby et al provide additional evidence to this. And when you study the neurophysiology of new fathers, you do find that there are changes.

If one has to conclude in that line of thought, normal life must have to be that stressful like war to produce schizophrenia which is indeed not a fact Moreover, it is equally true that many people develop schizophrenia without experiencing significant life stresses probably because of the biological factors even if they are kept away from stress.

Coleman reports that this view has been supported by pharmacological experiments demonstrating that cortical stimulants like caffeine temporarily abolish or diminish hallucinations. Also notable is the observation that in any single individual with the illness, symptoms fluctuate and change over time, making it hard to invoke permanent cerebral changes in neuronal function or circuitry as the basis of these cerebral abnormalities.

The genetic theorists thus view that schizophrenia occurs frequently among people who are closely related and more so when the genetic similarlity is closer. The schizophrenics will continue to be what they are and have a marginal existence after being discharged from the hospital.

However, researches in this area do not lead to any generalised conclusion supporting early atypical developments being the characteristics of individuals who show schizophrenic reactions.

In support of her view she found in 3 or 4 schizophrenic the gonads are microscopically normal.

3) Biological explanations of schizophrenia

Research into this gene and related genes is ongoing, so it is not yet possible to use the genetic information to predict who will develop the disease Janicak et al. While cortical depressants like bromides intensify them.

From the schizophrenic point of view an attitude which considers their illness as positive experience may have beneficial effects. These studies on adoptees shacked the field of genetic research in schizophrenia. Immigration, industrialization, urbanization and abrupt change contribute to the aetiology of schizophrenia as it becomes quite difficult to adjust to such abrupt changes.

Ketyb has reported that the percentage of schizophrenia spectrum disorders in biological relatives of schizophrenic adoptees is significantly greater than in non-biological relatives.

For example, fluid-filled cavities at the center of the brain, called ventricles, are larger in some people with schizophrenia. Analysis of these studies on adoptees thus leads one to conclude that the probability of one becoming schizophrenic is more with those having a defective genetic background.

It is very good reading for anyone interested in the topic of how interpersonal relationships impact our biology. Brain dysfunction Using brain imaging techniques, such as P. Neurotransmitters, substances that allow communication between nerve cells, have long been thought to be involved in the development of schizophrenia.

They have studied populations where the risk of schizophrenia is considered very high due to several genetic factors such as close relatives of schizophrenics showing higher incidence rates than distant relatives.The risk of schizophrenia increases if a person inherits specific variants in a gene related to “synaptic pruning”—the elimination of connections between neurons—according to a study from Harvard Medical School, the Broad Institute and Boston Children’s Hospital.

Biological/Genetic predisposition is at the root of schizophrenia - and there are likely significant variations in risk predisposition based on number of associated genes, and prenatal factors, etc. a person experiences early in life.

Being the most complex functional psychoses, the wide range of dysfunctions commonly found in all types of schizophrenia cannot be fully explained by any single theory advanced to explain the causes of schizophrenia.

Jan 02,  · 3) Biological explanations of schizophrenia. There are several different explanations for the disorder schizophrenia. One of these explanations is the biological model. This model explains schizophrenia through biological faults, for example viral infections and brain abnormalities.

Tracing the genetic basis of the cerebral mechanisms that, might, express a particular genetic defect in psychosis or in a disease like schizophrenia will require specific information about, the human schizophrenic brain.
