Schizophrenia: A Case Study

What is Schizophrenia? How much it is dangerous? Before Answering the questions, let me tell you my friend’s story here. His brother got “Schizophrenia” He told me that “John is my younger brother. He genuinely liked Justin Bieber more than me. Also, He had repeatedly been adopting the first key position in his school. He was always a cheerful, intelligent and brave boy. His eyes are outstandingly beautiful, and my mother used to say he is most of my sons. By the way, we are five brothers but his unique individuality was undoubtedly the most different. Above all, He was always a pleasant stay at a lovely home. Therefore, everyone used to giggle gleefully and kept laughing all over with him.”

Tragedy Era

After some time his study was upset. As a result, his behavior at home became something extraordinary and unusual.
So, He kept silent and lived solely. The family did not value this at the beginning. A few days later we found out that he started to get intoxicated. But it’s a matter of time later. He had become a drug addiction until then. But the urgent matter was not just drug addiction. Also, In the present circumstances, he started performing psychological movements too. Furthermore, Just like staying alone, talking to himself, laughing sometimes, answering himself of odd questions and ever sitting, ever jumping, etc.

Constantly say “I came from another country I am not from you. I don’t belong with you. I remain a partner of GOD, and we produced this world. My Role is bigger than him” etceteras.

Consulting a Psychiatrist

Furthermore, He told me that “We thought it was because of drug consumption. Therefore We contacted many psychologists. Also, We tearfully described the doctor that he has become a drug addict. His treatment was initiated But no benefit. We went changing the psychiatrist but did not gain any particular advantage. However, the effect of the used medicine was a short time, but not forever”

My friend’s family was only concentrating on Drug addiction issue but on the other hand, this complex disease has increased sufficiently. And after that, the condition was built he did not care about his personal cleanliness. Consequently, there is no bath for weeks. Wake up all night, breaking home appliances, like TV oven, cups, mugs, plates. Throwing things out of the freezer and sometimes eating more and sometimes lesser than a normal person. Above all, Meaning precisely a loss of home. As a result, they contacted a highly professional psychiatrist and disease diagnosed as “Schizophrenia”. Finally, Now the Patient is under treatment.

What is Schizophrenia? Schizophrenia signs and symptoms

Schizophrenia is a disorder that affects a person’s ability to think, feel, and behave clearly.

My friend wanted to know what is the root cause of Schizophrenia? the exact cause of it. Hence, He asked this question on “Quara” and He got some answers by Susan Canady and Mark. They wrote answers to his question that Schizophrenia is genetic.

Furthermore, They told That means that there are ‘misspellings’ in genes we all have. Every gene location is a recipe, a code for creating one single substance. Each substance is something our body needs for some process. In this mental illness, the gene locations(it is always more than one gene location), are those that guide and control how the brain develops long before birth. As a result, there are some very small, subtle errors in brain development long before birth. Usually, it is near adulthood, when the brain undergoes a final burst of change and ‘rewiring,’ that these subtle errors are uncovered. It is more the brain’s natural attempts to repair these mistakes that cause schizophrenia symptoms. As a result of the original errors in the development of the brain, and the brain’s attempts to fix and make up for these errors, it’s symptoms begin.

The question is what causes the gene misspellings?

schizophrenia is most likely to be characterized by

They can be inherited from parents with schizo illness, bipolar and other disorders. They can occur on their own. I would call them ‘mutations,’ but that word always makes people think of Godzilla movies and giant ‘mutated’ ant movies, where something ‘causes’ the DNA to be ‘mutated’, and that creates a monster.

Nature of Genes

It is really the nature of genes to make spelling errors. Yes, that really is the nature of all the processes involving genes. Think about it. We start out as one cell. Then in the process of growth prior to birth, one cell splits into two, two split into four, and so on. EACH TIME this happens the DNA of that cell must uncurl and unzip, and copy itself. Yes, mistakes happen. Certain stretches of the DNA are more prone to misspelling than others. These mistakes are no one’s fault. They just happen. Nobody did anything wrong. It just happens. And as a result people have disorders and it is our God-given responsibility to give them compassion and understanding.

This question represents a very, very common misunderstanding about hallucinations.

Hallucinations are not spirituals

Hallucinations are not some type of spiritual experience, nor are they some sort of philosophical/existential football that people can kick around during clever-sounding debates about reality or deciding what’s real.

mental disorders in children

They are neurological – a miscommunication in the brain. fMRI and PET scan actually allow one to see the hallucination form and spread to the rest of the brain.

In schizo disorder, about 3–6 weeks before auditory hallucinations start, certain brain cells are lost by apoptosis. Let us say those cells were in the ‘hearing’ centers of the brain. The brain can then attempt to ‘manufacture’ the sensory info that has been lost. That’s the hallucination.
We can in fact prove that those cells have been apoptosis and are missing. And this happens very shortly before hallucinations start.

Replacing the memory cells

WHY? Well, at certain stages in our growth, our brains get ‘cleaned up’ – pruned – just like it sounds, brain cells get eliminated, brain cell connections get eliminated. That’s supposed to happen. That’s a natural process. But in schizo disorder that clean up gets misdirected, I can explain how in another thread. But as a result, some brain cells are lost. So. The brain takes our sensory input and basically…’ paints an image.’ Or tries to!

If due to this illness (or similar disorders), it can’t complete that picture, the brain attempts to ‘fill in the blanks’ and complete that picture. That’s when hallucinations occur. Similarly, I have tinnitus. I hear a ringing sound. There is nothing within the setting creating that noise. My brain is literally ‘manufacturing’ that noise in the parts of the brain that process sound.

Why hallucinations are not real?

mental disorders types

WHY? Because the brain can’t ‘complete the picture.’ Some of the cells in my brain that hear certain sound frequencies*, have aged or been damaged(by loud noise) and are no longer able to process those frequencies. To attempt to compensate, my brain has done several things.

It has increased my sensitivity to similar frequencies
It has tried to replace the lost frequency as best it can
As a result, I hear distorted sounds. If we were using terminology consistently, we’d say I had tinnitus hallucinations. The rest of our sensory capability isn’t in the slightest degree not like our hearing. And hallucinations are very much like tinnitus.

Vision is just specific as hearing

Vision is just as specific as hearing. For example, a cluster of cells in the brain is responsible for processing ONLY information about human figures in silhouette coming toward you in the bright sun. Oh yeah, it’s that specific. Disrupt those specific brain cells, that’s your hallucination. Similarly, we have specialized cells in the parietal lobe (I think it’s the parietal lobe….will look it up in a sec) that are responsible for depth perception. Disrupt those brain cells, and a figure in a painting leaps out at you. That’s your hallucination.

*Sound ‘frequencies’ refer to the range of sounds. From a high squeak of a kitten to a low rumble of an elephant. We hear sounds in the range of 20 to 20,000 Hertz. Therefore Our best hearing is 1000–5000 Hertz (human speech range). Our hearing apparatus has cells that specialize in each frequency. Sound travels in waves, and Hertz is a measure of how many waves per second. So, High pitched sounds have more waves per second.

Schizophrenia icd 10 and Schizophrenia dsm 5 Coding Document

As we know that Every coder knows that we can only code what is documented. Mental health providers typically do a great job at documenting the elements needed to code to the highest level of specificity, but often our primary care and specialty physicians will list a mental health diagnosis in the patient’s assessment and fail to document the specificity needed to code properly, leaving the coder with no choice but to select an unspecified code.

Schizophrenia ICD 10

To document and subsequently code schizophrenia in ICD-10-CM, let’s first take a look at what is different between ICD-9-CM and ICD-10-CM. In ICD-9-CM, it has two classifications. However, The first classifies the subtype of schizo disorder – these subtypes are categorized as a simple, disorganized, catatonic, paranoid, schizophreniform disorder, latent schizophrenia, residual, schizoaffective disorder, and “other” specified type of schizophrenia. Also, The second classification in ICD-9-CM is the acuity: subchronic, chronic, subchronic with acute exacerbation, chronic with acute exacerbation, and in remission.

Schizophrenia DSM 5

Secondly, According to DSM-5, the diagnostic criteria no longer identify subtypes or acuity. Subtypes had been defined by the predominant symptom (indications) at the time of evaluation. But these were not useful to clinicians, because patients’ symptoms frequently changed from one subtype to another and presented overlapping subtype symptoms, which blurred distinc­tions among the subtypes and decreased their validity. ICD-10-CM eliminated the acuity of schizo disorder; however, it did not eliminate the subtype. Therefore, ICD-10-CM diagnoses codes are not in harmony with DSM-5.

However, ICD-10-CM did update the schizophrenia subtypes from the ICD-9-CM classification. So, the ICD-10-CM category for schizophrenia (F20) includes the subtypes paranoid, disorganized, catatonic, undifferentiated, residual, and “other.”

What is the difference between ICD 10 and ICD 9?

ICD-9 has approximately 13,000 (thirteen thousand) codes whereas ICD-10 has 68,000 (sixty-eight thousand). In addition, ICD-10 codes are alphanumeric whereas ICD-9 codes contain numbers only. Specificity: ICD-10 codes allow providers to provide detail such as to cause, anatomic site, severity, and type of encounter such as initial, subsequent, or sequela.

Simple Schizophrenia

Simple-type schizophrenia is a sub-type of schizophrenia as defined in the International Classification of Diseases (ICD-10).[1] It is not included in the current Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Simple-type schizophrenia is characterized by negative (“deficit”) symptoms, such as avolition, apathy, anhedonia, reduced affect display, lack of initiative, lack of motivation, low activity; with the absence of hallucinations or delusions of any kind.

Disorganized schizophrenia

Disorganized Schizophrenia is one of the five (5) subtypes of schizophrenia. In other words, It is characterized by disorganized behavior and speech and includes disturbance in emotional expression. Hallucinations and delusions are less pronounced with disorganized schizophrenia, though there is evidence of these symptoms occurring.

Catatonic Schizophrenia

Catatonic Schizophrenia is a state of psycho-motor immobility and behavioral abnormality manifested by stupor. However, Affected people may exhibit dramatic reduction inactivity, to the point that voluntary movement stops, as in catatonic stupor. So alternatively, the activity can dramatically increase, a state known as catatonic excitement. Therefore, many other disturbances of movement can be present with this subtype.

Paranoid Schizophrenia

Paranoid schizophrenia remains the most familiar type of schizophrenia. Also, It is typically the most common subtype of Schizophrenia. These debilitating symptoms straddle the line between what is real and what isn’t. Paranoid schizo is undoubtedly a lifelong disease. As a Result, Paranoid schizo manifests itself in a complex array of symptoms. Also, Common signs for paranoid schizophrenia include auditory hallucinations (hearing voices or sound effects) and paranoid delusions (believing everyone is out to cause the sufferer harm). However, two of the symptoms carefully separate this specific form of schizophrenia from other forms.

mental disorders definition


Schizophreniform disorder remains a specific type of psychotic illness with symptoms similar to those of schizophrenia but lasting for less than 6 typical months. Like schizophrenia, the schizophreniform disorder represents a type of “psychosis” in which a person cannot relate what is real from what is imagined.

Latent Schizophrenia

Latent Schizophrenia is a mental disorder that affects a person’s ability to tell what is real and not real, to act normal, and to think clearly, but with no history of schizophrenic episodes. Hence, the symptoms of Latent Schizophrenia include isolation, hallucinations, delusions, and trouble concentrating.

Residual schizophrenia

Residual schizophrenia is a type of schizophrenia where a person displays mostly the negative symptoms of schizophrenia.


Schizoaffective is mood disorder like Mania and depression characterized primarily a symptom of schizophrenia. Hence it is called Schizoaffective.
