How Is Schizophrenia Diagnosed

Positive Symptoms and Negative Symptoms of Schizophrenia

You may be diagnosed with schizophrenia if you experience at least two of the following symptoms for at least 1 month, and signs of the condition possibly in milder form persist for at least 6 months. Also, at least one symptom must be from among the first three on this list:

  • delusions
  • disorganized speech, such as frequent derailment or incoherence
  • grossly disorganized or catatonic behavior
  • negative symptoms, such as reduced emotional expression or total lack of motivation

To be diagnosed with schizophrenia, your healthcare provider will also consider what degree symptoms negatively affect different aspects of your life, such as your work, academic performance, interpersonal relationships, or self-care.

Your medical professional will also rule out any other possible causes of your symptoms, such as schizoaffective disorder, mood disorder with psychotic features, autism spectrum disorder, a general medical condition, or substance use disorder.

Keep in mind that about half of people with schizophrenia have co-occurring mental or behavioral health conditions, such as


If you experience delusions, you believe an untruth.

For instance, you may think that youre in danger and someone wants to hurt you when theres no evidence to that effect.


If you see, hear, smell, taste, or feel something that isnt real, youre experiencing hallucinations.

For example, people with schizophrenia may hear voices.

Disorganized thinking

Abnormal body movements

What Are Positive And Negative Symptoms

Treatment For Positive Symptoms In Schizophrenia

Atypical antipsychotics typically do a good job at reducing the rate at which an individual experiences positive symptoms of schizophrenia. This is because they block dopamine receptors from being flooded with dopamine in the brain. There really arent any other current ways to treat these positive symptoms in schizophrenia other than utilize the pharmaceutical technology that is available.

As science advances and we get a better understanding of the specifics of schizophrenia, we should be able to develop better treatment options. Until then, you may want to check out some natural remedies for schizophrenia that may be used as an effective augmentation strategy to reduce symptoms.

Understanding The Term Of Psychosis Based On The Example ...

Nowadays we tend to think of the various symptoms of schizophrenia as falling into two groups. There are the positive symptoms such as delusions and hallucinations and then there are the negative symptoms such as apathy, lethargy and social withdrawal. To understand more about how these symptoms affect people with schizophrenia take a look at our information sheet on understanding negative symptoms.

Without a doubt, the advent of the antipsychotic medicines in the 1950s heralded a new era in the treatment of schizophrenia. About 70 80 % of people with schizophrenia who take antipsychotic medication will find that their positive symptoms such as delusions and hallucinations are reduced and in some cases they may disappear altogether1.

The first generation of antipsychotics known as typical are very beneficial for the positive symptoms of schizophrenia but have no effect on negative symptoms.

The discovery of these drugs greatly changed the outlook for people diagnosed with schizophrenia. Before these drugs were introduced about 70% of people with schizophrenia in the UK were confined in mental hospitals, often for many years and sometimes for life. Today, only about 5% of people with schizophrenia are in hospital and the average length of stay is only a few months.

Over the years a number of possibilities for treating negative symptoms have been practiced or proposed although it has to be said that each has had varying degrees of success in practice.

The Vexing Issue Of Validity Versus Utility

Positive and Negative Symptoms of Schizophrenia

There is no single agreed meaning of validity in science, although it is generally accepted that the concept addresses the nature of reality. Psychologists generally adopt the distinction between content, criterionrelated, and construct validity, and their main concern has been with the validity of psychological tests. Borrowing terminology from psychometric theory, psychiatrists have mainly been concerned with concurrent and predictive validity, partly because of their relevance to the issue of the validity of diagnoses. The ability to predict outcome, both in the absence of treatment and in response to specific therapies, has always been a crucial function both of physicians and of their diagnoses. Robins and Guze proposed several formal criteria for establishing the validity of psychiatric diagnoses: clinical description laboratory studies delimitation from other disorders follow-up studies and family studies. This schema was elaborated by Kendler who distinguished between antecedent validators concurrent validators and predictive validators . Andreasen has proposed a second structural program for validating psychiatric diagnosis and listed several additional validators-molecular genetics and molecular biology, neurochemistry, neuroanatomy, neurophysiology and cognitive neuroscience – all potentially capable of linking symptoms and diagnoses to their neural substrates.

Positive Symptoms Of Schizophrenia: Things That Might Start Happening

Positive symptoms are highly exaggerated ideas, perceptions, or actions that show the person canât tell whatâs real from what isnât. Here the word “positive” means the presence of symptoms. They can include:

  • Tactile. This creates a feeling of things moving on your body, like hands or insects.
  • Delusions. These are beliefs that seem strange to most people and are easy to prove wrong. The person affected might think someone is trying to control their brain through TVs or that the FBI is out to get them. They might believe they’re someone else, like a famous actor or the president, or that they have superpowers. Types of delusions include:
  • Persecutory delusions. The feeling someone is after you or that youâre being stalked, hunted, framed, or tricked.
  • How Can You Treat Schizophrenia

    Schizophrenia treatment, as of now, usually continues for lifelong, right from the time of diagnosis. Treatment for schizophrenia needs to be continued even when the schizophrenia symptoms seem to have subsided or faded. Schizophrenia treatment is generally a combination of medication, coordinated specialty care services and psychotherapy. A team that comprises of a psychiatrist, psychiatric nurse, social worker and psychologist should guide the schizophrenia treatment.

    Medications acts as a foundation in schizophrenia treatment. Antipsychotic medication and anti-tremor medications are commonly prescribed to schizophrenic patients. The combinations of various neuro-psychotic medications as well as doses are decided based on the severity of the schizophrenia symptoms.

    Along with medications, schizophrenic patients also need strong social support. This is also referred to as psychological intervention and following are some of these therapies:

    Family Therapy in Schizophrenia: This therapy educates the family on how to support and deal with the family member suffering from schizophrenia.

It also helps the individuals to be able to manage their illness overall.

    What Are The Symptoms Of Schizophrenia And How Is It Diagnosed

    How is schizophrenia diagnosed?

    Only a psychiatrist can diagnose you with schizophrenia after a full psychiatric assessment. You may have to see the psychiatrist a few times before they diagnose you. This is because they need to see how often you are experiencing symptoms.

    There are currently no blood tests or scans that can prove if you have schizophrenia. So, psychiatrists use manuals to diagnose schizophrenia and other mental illnesses.

    The 2 main manuals used by medical professionals are the:

    • International Classification of Diseases which is produced by the World Health Organisation , or
    • Diagnostic and Statistical Manual which is produced by the American Psychiatric Association .

    NHS doctors use the ICD-10.

    The manuals explain which symptoms should be present, and for how long for you to receive a diagnosis. For example, according to the NHS you need to be hearing voices for at least 1 month before you can be diagnosed. Mental health professionals may say you have psychosis before they diagnose you with schizophrenia.

    What is the future of diagnosis in schizophrenia?There are many research studies being conducted across the world on how to better diagnose schizophrenia. For example, a recent study found through looking at images of the brain, there may be different sub-types of schizophrenia.

    What are the symptoms of schizophrenia?

    The symptoms of schizophrenia are commonly described as positive symptoms or negative symptoms. This doesnt mean that they are good or bad.

    The Present Diagnostic Classifications: Dsm

    There are both similarities and differences in the way the two classifications define schizophrenia. In contrast to DSM-IV, which provides a single set of operational diagnostic criteria for all users, ICD-10 was designed as a family of inter-related versions addressing different users. While the ICD-10 volume Clinical Descriptions and Diagnostic Guidelines is the conceptual core of the system, the ICD-10 Diagnostic Criteria for Research and the WHO Guide to Mental Health in Primary Care are derivatives for use in specific context. A comparison of the two sets of diagnostic criteria is provided in Tables IV and V.

    List Of Negative Symptoms Of Schizophrenia

    There are two types of negative symptoms. Differentiating between the two can be a challenge.

    Primary negative symptoms refer to those that are part of the disorder itself. These can occur during or between exacerbations.

    Secondary negative symptoms refer to those due to other things, such as:

    • medication
    • inappropriate emotions for the situation

    Positive symptoms are more apparent, so theyre likely to prompt diagnosis and treatment.

    On the other end of the spectrum, negative symptoms mean something is missing. That makes them easier to overlook as being linked to schizophrenia.

    Relationship Between The Brain And Negative Symptoms

    Research has described how brain chemistry and malfunction seems to be a contributing factor to developing schizophrenia. However, it is said that schizophrenia affects the interaction between the centers of judgement and planning in the pre-frontal cortex and the centers of emotion and memory in the temporal lobes and limbic system .

    One of the theories for schizophrenia indicates that the brains noise level rises when the excitatory neurotransmitter glutamate becomes overactive in the prefrontal cortex and at the same time stimulates receptors for another neurotransmitter, dopamine, in the limbic region .

    In accordance with this theory, glutamate activity seems to result in the manifestation of negative and cognitive symptoms , and psychotic symptoms seems to be a result of dopaminergic activity in the limbic system.

    The reward circuits are said to be located in the limbic system, this is why patients with schizophrenia are said to have a malfunction in their reward system when they seem to want too little, related to volition. This is why the original antipsychotic drugs targeted the nerve receptors in the limbic system, suppressing the activity of the neurotransmitter dopamine.

    According to health.harvard.edu, All of them are roughly equally good at suppressing psychotic symptoms and equally ineffective against negative symptoms whether the source of these symptoms is schizophrenia or another disorder.

    What Are The Types Of Schizophrenia

    What are Positive and Negative Symptoms of Schizophrenia/Schizoaffective Disorder?

    There are different types of schizophrenia. The International Classification of Diseases manual describes them as below.

    Paranoid schizophrenia

    • Pranks, giggling and health complaints.
    • Usually diagnosed in adolescents or young adults.

    Catatonic schizophrenia

    • Unusual movements, often switching between being very active and very still.
    • You may not talk at all.

    Simple schizophrenia

    • Negative symptoms are prominent early and get worse quickly.
    • Positive symptoms are rare.

    Undifferentiated schizophrenia

    Your diagnosis may have some signs of paranoid, hebephrenic or catatonic schizophrenia, but doesnt obviously fit into one of these types alone.

    Residual schizophrenia

    This type of schizophrenia is diagnosed in the later stages of schizophrenia. You may be diagnosed with this if you have a history of schizophrenia but only continue to experience negative symptoms.

    Other schizophrenia

    There are other types of schizophrenia according to the ICD-10, such as.

    • Cenesthopathic schizophrenia. This is where people experience unusual bodily sensations.
    • Schizophreniform. Schizophreniform disorder is a type of psychotic illness with symptoms similar to those of schizophrenia. But symptoms last for a short period.

    Unspecified schizophrenia
