Can C-Scans show evidence of Schizophrenia?

Now I have heard or read somewhere down the line, that schizophrenia shows up on C-Scans.I have been dx with schizophrenia and I have had psychotic breaks. I have been doing a lot better for the last year.

When I had my last "break"...my P Doc ordered a C-Scan. I really would like to know the truth.Can anyone answer this question for me?

Thank you!

As far as I know chemical imbalance of the brain does not show up on c scans unless it is caused by tomors aneurysms and other physical ailments in which case its the tumors and aneurysms that show up not the chemical imbalance.. C scans are a type of x ray they can only detect physical problems not mental problems. Your doctor was probably ruling out tumors and so on first before diagnosising as schitophrenia. especially if this is a medical doctor not a psychiatrist or psychologist who would have used a test called a Comprehensive Psychological Evaluation to diagnose the schitophrenia.

I have read and heard that a PET scan can show Bi Polar and maybe it does show schizophrenia.......You can google PET SCAN and see if it does

I think myself nailed it, as usual: Your doc was probably trying to rule out lesions and such. In any case, you have every right to ask your doc about this and demand some answers.

This wasn't part of the original question, but since it came up: It seems like MRI's might be able to detect signs of schizophrenia, but only if a series are conducted over a long period of time. (A single image won't show it -- multiples are required so that a pattern of change can be detected.) Also, this seems more effective for early onset than later in the course of things. I only understand the bare essentials of MRI, though, so take everything I've said with a grain of salt.

LOLOLOL Thanks Justben. Glad to know this brains thirst for knowledge in understanding my assorted physical and mental problems comes in handy in helping others. (Though I have been known at times come off as a "know it all" because of this.)

Other than what myself said (which is likely true) the doctor could have been looking for enlarged ventricles in the brain that are a physiological marker for schizophrenia. Often people with schizophrenia have these enlarged ventricles (which are spaces in the brain that contain cerebrospinal fluid) though it is uncertain how they are exactly related to schizophrenia. (ie: cause/effect/correlation...)

Thanks to all who replied. I think I understand a little more now.

Dottie, Hi, I may have read an article in Discover Magazine.
You might could check their archives.

I have a son with schizophrenia, & my understanding of the matter is that the enlarged ventricles in the brain are caused by the drugs used to treat it. I may be able to dig out some journal articles. Some of the drugs are worse for this than others, & some of them just don't suit certain people.
They are still arguing about this matter in the journals, but all the evidence I have read has lead me to the above conclusion.

Try this link. I checked with Discover Magazine...but you can only read the article if you subscribe.

Yes indeed c-scans do infact show schizophrenia, it shows it as dark areas of the brain I know because I have schizophrenia and, have also had two strokes so I've had c-scans galore and mri's and mra's etc.. and the doctor pointed out very clearly my schizophrenia on the scans.

Dark spots on c scans and MRI's = dead brain cells, tumors aneurysms, blocked arteries. a normal brain scan Also shows a dark middle area - a type of hollow shaped sort of like a butterfly. Sometimes when they do various scans they inject radioactive isotopes into the blood stream to detect aneurisms and blockages in the blood stream. Scans are like X rays. They can detect normal size vs abnormal size, shape of the main hollow area in the middle and physical problems like blood flow, Aneurysms, tumors, epilepsy but cannnot test for the various chemicals in the brains synapses such as dopamine, lithium. Only by drawing blood and sending that blood to a lab can the chemicals of the body - lithium, dopamine, potasium, iron, calcium, phosphorus, sodium and so on.

Mental health disorders are detected through a psychiatrist, psychologist giving a Comprehensive Psychological Evaluation. You can find details of what that test includes for the diagnosis of mental disorders in my blog. Tests for Schzophrenia are - in part the MMPI (Minnesota Multiphasic Personality Inventory and tests for Narcessistic, Schizophrenia, Borderline Personality Disorder, Schto-affective, paranoia, depression and a few others that I cant remember at the moment.)and the MCMI (Millon Clinical Multiaxial Inventory), an interview an hour or more in length with a psychiatrist or psychologist, an IQ test called Wechsler Adult Intelligence Scale, TAT, Rorshacks (Spelling wrong but its the ink blots test) Once all these are scored the person has their diagnosis (disorders listed in the DSM) on the Axis I,II, III, IV, and V. Your therapist can explain the procedures for and content of psychological testing in more detail.

Well I appriciate your feedback maybe I'm wrong I don't know.

not sure about CAT scan but PET scans do show evidence schizophrenia related to differences certain types of dopamine -- activity in the prefrontal cortex

z

zOey,is correct, PET scans can reveal if schizophrenia is present by the shape of the brain, and location of certain brain activity. The brain has a slightly different shape than a non-schizophrenic, which has also become an indicator for researchers.

COOL. Thanks for locating the updated info.

I found this information on schizophrenia.com -

How is Schizophrenia Diagnosed?

There is currently no physical or lab test that can absolutely diagnose schizophrenia - a psychiatrist usually comes to the diagnosis based on clinical symptoms. What physical testing can do is rule out a lot of other conditions (seizure disorders, metabolic disorders, thyroid disfunction, brain tumor, street drug use, etc) that sometimes have similar symptoms.

Current research is evaluating possible physical diagnostic tests (such as a blood test for schizophrenia, special IQ tests for identifying schizophrenia, eye-tracking, brain imaging, 'smell tests', etc), but these are still in trial stages at only a few universities and companies and are not yet widely used. It will likely be a few years before these on the market, and adopted by hospitals, etc.

People diagnosed with schizophrenia usually experience a combination of positive (i.e. hallucinations, delusions, racing thoughts), negative (i.e. apathy, lack of emotion, poor or nonexistant social functioning), and cognitive (disorganized thoughts, difficulty concentrating and/or following instructions, difficulty completing tasks, memory problems). Please refer to the information available on this page (see below) for common signs and symptoms, as well as consumer/family stories of how they identified schizophrenia in their own experiences. However, only a psychiatrist can make a diagnosis and start a treatment program. If you are experiencing symptoms are bothersome, debilitating, or harmful, please we recommend you try the on-line Screening test for identification of early schizophrenia symptoms (click here to go to the test) that we offer on this web site. The on-line test is also available in an "off-line version" for print-out (valuable for testing a family member who is not on-line, or who may not like the site of a schizophrenia-focused web site) - and the responses can then be entered into the on-line version of the test for scoring. If you test positive you may want to go to to an early psychosis diagnosis and treatment center or make an appointment with your doctor and/or a psychiatrist.


The First Steps Towards Proper Diagnosis

The first step in getting treatment for schizophrenia is getting a correct diagnosis. This can be a more difficult than it might seem, because the symptoms of schizophrenia can be similar at times to other major brain disorders, such as bipolar disorder (manic-epression) or even major depression. Another issue is that a person with schizophrenia may be paranoid or believe that nothing is wrong with them, and therefore may not want to go to see a doctor. Because many regular family doctors may not be very familiar with schizophrenia, it is important to see a good psychiatrist that is experienced in the diagnosis and treatment of schizophrenia.

One way to do this is to contact a local support group that deals with brain disorders such as schizophrenia, and talk to the other members that already have experience with the local psychiatrists. If that is not convenient, we recommend you join in our discussion areas (see "parents" area or "Main Area" listed on home page) and ask there if anyone can recommend a good psychiatrist in your area. Local members may be able to recommend a good psychiatrist experienced in schizophenia that they have worked with.

See our FAQ guide, with sections on finding and working with a good psychiatrist. This is a vital part of the treatment and recovery process, as research and anecdotal evidence both confirm that a good patient-doctor relationship can be important for enhancing treament compliance.

If you have a family history of schizophrenia, psychiatric illness, or other serious conditions in your family, it can be a great help to the doctor if you create a Health Family Tree that tracks such diseases through family generations. Having a family health history in front of them can help providers decide which diagnostic and screening tests are most appropriate for you or your loved one. Create your own Health Family Tree with this free, web-based software (provided by the Health and Human Services Dept).

As with most serious illnesses, its important to get diagnosis and treatment as quickly as possible. Getting treatment early can significantly improve an individual's chances at a partial or complete recovery by preventing further brain damage or other damage caused by the disease symptoms.

Symptoms of Schizophrenia

Schizophrenia is characterized by profound disruption in cognition and emotion, affecting the most fundamental human attributes: language, thought, perception, affect, and sense of self. The array of symptoms, while wide ranging, frequently includes psychotic manifestations, such as hearing internal voices or experiencing other sensations not connected to an obvious source (hallucinations) and assigning unusual significance or meaning to normal events or holding fixed false personal beliefs (delusions). No single symptom is definitive for diagnosis; rather, the diagnosis encompasses a pattern of signs and symptoms, in conjunction with impaired occupational or social functioning (Source: DSM-IV -available for purchase on Amazon.com Diagnostic and Statistical Manual of Mental Disorders DSM-IV-TR).
Symptoms are typically divided into positive and negative symptoms because of their impact on diagnosis and treatment. Positive symptoms are those that appear to reflect an excess or distortion of normal functions. The diagnosis of schizophrenia, according to DSM-IV, requires at least 1-month duration of two or more positive symptoms, unless hallucinations or delusions are especially bizarre, in which case one alone suffices for diagnosis. Negative symptoms are those that appear to reflect a diminution or loss of normal functions. These often persist in the lives of people with schizophrenia during periods of low (or absent) positive symptoms. Negative symptoms are difficult to evaluate because they are not as grossly abnormal as positives ones and may be caused by a variety of other factors as well (e.g., as an adaptation to a persecutory delusion). However, advancements in diagnostic assessment tools are being made.

Diagnosis is complicated by early treatment of schizophrenia’s positive symptoms. Antipsychotic medications, particularly the traditional ones, often produce side effects that closely resemble the negative symptoms of affective flattening and avolition. In addition, other negative symptoms are sometimes present in schizophrenia but not often enough to satisfy diagnostic criteria (DSM-IV): loss of usual interests or pleasures (anhedonia); disturbances of sleep and eating; dysphoric mood (depressed, anxious, irritable, or angry mood); and difficulty concentrating or focusing attention.

Currently, discussion is ongoing within the field regarding the need for a third category of symptoms for diagnosis: disorganized symptoms. Disorganized symptoms include thought disorder, confusion, disorientation, and memory problems. While they are listed by DSM-IV as common in schizophrenia—especially during exacerbations of positive or negative symptoms (DSM-IV)—they do not yet constitute a formal new category of symptoms. Some researchers think that a new category is not warranted because disorganized symptoms may instead reflect an underlying dysfunction common to several psychotic disorders, rather than being unique to schizophrenia.

Diagnostic criteria for schizophrenia (USA criteria)

Characteristic symptoms: Two (or more) of the following, each present for a significant portion of time during a 1-month period (or less if successfully treated):

Delusions - false beliefs strongly held in spite of invalidating evidence, especially as a symptom of mental illness: for example,
Paranoid delusions, or delusions of persecution, for example believing that people are "out to get" you, or the thought that people are doing things when there is no external evidence that such things are taking place.
Delusions of reference - when things in the environment seem to be directly related to you even though they are not. For example it may seem as if people are talking about you or special personal messages are being communicated to you through the TV, radio, or other media.
Somatic Delusions are false beliefs about your body - for example that a terrible physical illness exists or that something foreign is inside or passing through your body.
Delusions of grandeur - for example when you believe that you are very special or have special powers or abilities. An example of a grandiouse delusion is thinking you are a famous rock star.
Hallucinations - Hallucinations can take a number of different forms - they can be:
Visual (seeing things that are not there or that other people cannot see),
Auditory (hearing voices that other people can't hear,
Tactile (feeling things that other people don't feel or something touching your skin that isn't there.)
Olfactory (smelling things that other people cannot smell, or not smelling the same thing that other people do smell)
Gustatory experiences (tasting things that isn't there)
Disorganized speech (e.g., frequent derailment or incoherence) - these are also called "word salads".
Grossly disorganized or catatonic behavior (An abnormal condition variously characterized by stupor/innactivity, mania, and either rigidity or extreme flexibility of the limbs).
Negative symptoms, these are the lack of important abilities. Some of these include:
lack of emotion - the inability to enjoy acitivities as much as before
Low energy - the person sits around and sleeps much more than normal
lack of interest in life, low motivation
Affective flattening - a blank, blunted facial experession or less lively facial movements or physical movements.
Alogia (difficulty or inability to speak)
Inappropriate social skills or lack of interest or ability to socialize with other people
Inability to make friends or keep friends, or not caring to have friends
Social isolation - person spends most of the day alone or only with close family

Note: Only one Criterion A symptom is required if delusions are bizarre or hallucinations consist of a voice keeping up a running commentary on the person’s behavior or thoughts, or two or more voices conversing with each other.

Cognitive Symptoms of Schizophrenia
Cognitive symptoms refer to the difficulties with concentration and memory. These can include:
disorganized thinking
slow thinking
difficulty understanding
poor concentration
poor memory
difficulty expressing thoughts
difficulty integrating thoughts, feelings and behavior

Social/occupational dysfunction: For a significant portion of the time s+ince the onset of the disturbance, one or more major areas of functioning such as work, interpersonal relations, or self-care are markedly below the level achieved prior to the onset (or when the onset is in childhood or adolescence, failure to achieve expected level of interpersonal, academic, or occupational achievement).

Duration: Continuous signs of the disturbance persist for at least 6 months. This 6-month period must include at least 1 month of symptoms (or less if successfully treated) that meet Criterion A (i.e., active-phase symptoms) and may include periods of prodromal or residual symptoms. During these prodromal or residual periods, the signs of the disturbance may be manifested by only negative symptoms or two or more symptoms listed in Criterion A present in an attenuated form (e.g., odd beliefs, unusual perceptual experiences).

Schizoaffective and mood disorder exclusion: Schizoaffective disorder and mood disorder with psychotic features have been ruled out because either (1) no major depressive, manic, or mixed episodes have occurred concurrently with the active-phase symptoms; or (2) if mood episodes have occurred during active-phase symptoms, their total duration has been brief relative to the duration of the active and residual periods.

Substance/general medical condition exclusion: The disturbance is not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition.

Relationship to a pervasive developmental disorder: If there is a history of autistic disorder or another pervasive developmental disorder, the additional diagnosis of schizophrenia is made only if prominent delusions or hallucinations are also present for at least a month (or less if successfully treated).

Positive Symptoms of Schizophrenia
Delusions are firmly held erroneous beliefs due to distortions or exaggerations of reasoning and/or misinterpretations of perceptions or experiences. Delusions of being followed or watched are common, as are beliefs that comments, radio or TV programs, etc., are directing special messages directly to him/her.

Hallucinations are distortions or exaggerations of perception in any of the senses, although auditory hallucinations (“hearing voices” within, distinct from one’s own thoughts) are the most common, followed by visual hallucinations.

Disorganized speech/thinking, also described as “thought disorder” or “loosening of associations,” is a key aspect of schizophrenia. Disorganized thinking is usually assessed primarily based on the person’s speech. Therefore, tangential, loosely associated, or incoherent speech severe enough to substantially impair effective communication is used as an indicator of thought disorder by the DSM-IV.

Grossly disorganized behavior includes difficulty in goal-directed behavior (leading to difficulties in activities in daily living), unpredictable agitation or silliness, social disinhibition, or behaviors that are bizarre to onlookers. Their purposelessness distinguishes them from unusual behavior prompted by delusional beliefs.

Catatonic behaviors are characterized by a marked decrease in reaction to the immediate surrounding environment, sometimes taking the form of motionless and apparent unawareness, rigid or bizarre postures, or aimless excess motor activity.

Other symptoms sometimes present in schizophrenia but not often enough to be definitional alone include affect inappropriate to the situation or stimuli, unusual motor behavior (pacing, rocking), depersonalization, derealization, and somatic preoccupations.

Negative Symptoms of Schizophrenia

Affective flattening is the reduction in the range and intensity of emotional expression, including facial expression, voice tone, eye contact, and body language.

Alogia, or poverty of speech, is the lessening of speech fluency and productivity, thought to reflect slowing or blocked thoughts, and often manifested as short, empty replies to questions.

Avolition is the reduction, difficulty, or inability to initiate and persist in goal-directed behavior; it is often mistaken for apparent disinterest. (examples of avolition include: no longer interested in going out and meeting with friends, no longer interested in activities that the person used to show enthusiasm for, no longer interested in much of anything, sitting in the house for many hours a day doing nothing.)



Types of Schizophrenia
Paranoid schizophrenia - These persons are very suspicious of others and often have grand schemes of persecution at the root of their behavior. Halluciations, and more frequently delusions, are a prominent and common part of the illness.
Disorganized schizophrenia (Hebephrenic Schizophrenia) - In this case the person is verbally incoherent and may have moods and emotions that are not appropriate to the situation. Hallucinations are not usually present.
Catatonic schizophrenia - In this case, the person is extremely withdrawn, negative and isolated, and has marked psychomotor disturbances.
Residual schizophrenia - In this case the person is not currently suffering from delusions, hallucinations, or disorganized speech and behavior, but lacks motivation and interest in day-to-day living.
Schizoaffective disorder - These people have symptoms of schizophrenia as well as mood disorder such as major depression, bipolar mania, or mixed mania.
Undifferentiated Schizophrenia - Conditions meeting the general diagnostic criteria for schizophrenia but not conforming to any of the above subtypes, or exhibiting the features of more than one of them without a clear predominance of a particular set of diagnostic characteristics.

Misdiagnosis Issues

Because there is currently no physical test that confirms the presence of schizophrenia, and because schizophrenia often shares a significant number symptoms with other disorders, misdiagnosis is a common problem. According to one study surveying members of the National Depression and Bipolar Support Alliance, there is an average delay of 10 years from the first onset of symptoms to correct diagnosis and treatment of psychiatric disorders.

However, getting a correct diagnosis is necessary for finding a treatment program that works for you.

Being aware of the potential for misdiagnosis, and knowing what other disorders may appear like schizophrenia or vice-versa, will hopefully help you get started on the right treatment as soon as possible.

I am still looking into the possiblility of physical tests like MRI and other scans but still haven't found any that have American Psychiatric Association approval for scan diagnosis.

would love any info if anyone finds any psychiatric approval of scans because a relative has been diagnosed psychotic (and the diagnosis of schizophrenia was not denied.) So I am beginning to research this disorder.
