The changing epigenome informs gene expression

Epigenetic impact:
Epigenetic has a relationship with many disorders that include mental retardation associated disorders, immune system disorders, psychiatric disorders. Psychiatric disorders such as anxiety, schizophrenia, and other disorders have multiple factors contributing to the occurrence including both environmental and genetic.

The epigenome is the epigenetic state of the cell. The fertilized egg after getting developed into a newborn baby, lots of signals are received over days, weeks, and months that cause a lot of incremental changes in gene expression patterns. Epigenetic changes after recording the cell’s experiences on the deoxyribonucleic acid (DNA), which helps an individual to stabilize the expression of genes.

When each signal gets shuts down some genes and activate others as the process gets nudged into a cell towards the last stage. After having, different experiences that can cause the epigenetic profiles of each cell type to grow increasingly different over time. Finally, in the end, hundreds of cells form, each with a distinct identity and a specialized function. The epigenome changes in response to signals that come from inside the cell, from neighboring cells, or from the outside environment.

Epigenome is changeable:
The change takes place in epigenome when at different times of life different genes are needed.

The epigenome is changeable when cells are constantly listening for signals to change what cells are doing.

Signals come from inside the cell, neighboring cell, or the environment. Environmental signals can be direct that includes diet or indirect that includes stress.

Symptoms of schizophrenia :
The schizophrenia symptoms can be classified into three categories including, positive, negative, and psychomotor symptoms given below:

Positive symptoms:

The symptoms that have pathological excesses include delusions and hallucinations. Delusions are false belief held on inadequate grounds delusions involve delusion of persecution in which people believe that someone is threatening, the delusion of references in people attach special and personal meaning to objects and events, the delusion of grandeur in which people believe that special powers are within the individual, and other such delusions. Hallucinations are perceptions that occur in the absence of external stimuli, hallucinations involve auditory in which patients hear sounds or voices that do not exist, visual hallucinations in which people see visual images that do not exist, and other kinds of hallucinations.

Negative symptoms are pathological deficits that include poverty of speech, blunted effects, and flat affect, loss of violation, and social withdrawal. The poverty of speech is termed as alogia in which speech is reduced. Blunted affects mean feeling less anger, sadness, joy, and other feelings that most people do. Flat affects mean when an individual does not show any kind of emotions. People with schizophrenia may withdraw socially and become focused on their ideas and fantasies.

Psychomotor symptoms: Schizophrenics move less or make odd gestures and involves catatonic stupor that is people remain motionless, and silent for long periods, and other kinds of catatonia that include catatonic rigidity that is maintaining a rigid posture for hours, or catatonic posturing that means assuming bizarre positions for long periods.

Risk factors of schizophrenia:
In the disorder of schizophrenia, the main cause that involves risk factors is not known but many factors play an important role that involves family cause, pregnancy, and other birth complications, and many drug uses.

Schizophrenia is more related to a family history that means when other family members have schizophrenia the patient is more likely to get affected. For instance, when an individual’s mother has schizophrenia, the chances are more than the individual will also get affected.

The disorder of schizophrenia is more likely to occur during pregnancy times and births complications that involve malnutrition or other exposure to toxins or viruses that may impact brain development and schizophrenia will occur.

An individual after taking more of the drugs that include psychoactive or psychotropic drugs during teenage, or in adulthood that chances are more that the person will get schizophrenia.
