What are positive symptoms in schizophrenia?
Positive Symptoms of Schizophrenia: Things That Might Start Happening
- Hallucinations. People with schizophrenia might hear, see, smell, or feel things no one else does.
- Confused thoughts and disorganized speech.
- Trouble concentrating.
Cognitive Symptoms & Thinking Problems
These symptoms reflect how well the personâs brain learns, stores, and uses information.
Someone with schizophrenia might have a hard time with their working memory. For example, they may not be able to keep track of different kinds of facts at the same time, like a phone number plus instructions.
Along with having trouble paying attention, it can be hard for them to organize their thoughts and make decisions.
What If I Am A Carer Friend Or Relative
It can be distressing if you are a carer, friend or relative of someone who has schizophrenia. You can get support.
How can I get support for myself?
You can do the following.
- Speak to your GP about medication and talking therapies for yourself.
- Speak to your relatives care team about family intervention. For more information about family intervention see the further up this page.
- Speak to your relatives care team about a carers assessment.
- Ask for a carers assessment.
- Join a carers service. They are free and available in most areas.
- Join a carers support group for emotional and practical support. Or set up your own.
What is a carers assessment?NICE guidelines state that you should be given your own assessment through the community mental health team to work out what effect your caring role is having on your health. And what support you need. Such as practical support and emergency support.
The CMHT should tell you about your right to have a carers assessment through your local authority. To get a carers assessment you need to contact your local authority.
How do I get support from my peers?You can get peer support through carer support services or carers groups. You can search for local groups in your area by using a search engine such as Google. Or you can call our advice service on 0808 801 0525. They will search for you.
How can I support the person I care for?
You can do the following.

What Is The Cause Of Schizophrenia
The cause is not known for certain but there are several current ideas. It is thought that the balance of brain chemicals is altered. Neurotransmitters are needed to pass messages between brain cells. An altered balance of these may cause the symptoms. It is not clear why changes occur in the neurotransmitters.
Inherited factors are thought to be important. For example, a close family member of someone with schizophrenia has a 1 in 10 chance of also developing the condition. This is 10 times the normal chance. A child born to a mother and father who both have schizophrenia has a higher risk of developing it but one or more factors appear to be needed to trigger the condition in people who are genetically prone to it. There are various theories as to what these might be. For example:
- Stress such as relationship problems, financial difficulties, social isolation, bereavement, etc.
- A viral infection during the mother’s pregnancy, or in early childhood.
- A lack of oxygen at the time of birth that may damage a part of the brain.
- Illegal or street drugs may trigger the condition in some people. For example, heavy cannabis usage may account for between 8% and 14% of schizophrenia cases. Many other recreational drugs such as amfetamines, cocaine, ketamine and lysergic acid diethylamide can trigger a schizophrenia-like illness.
Rehabilitation And Community Support Services
Psychosocial skill training and vocational rehabilitation programs help many patients work, shop, and care for themselves manage a household get along with others and work with mental health care practitioners.
Supported employment, in which patients are placed in a competitive work setting and provided with an on-site job coach to promote adaptation to work, may be particularly valuable. In time, the job coach acts only as a backup for problem solving or for communication with employers.
Support services enable many patients with schizophrenia to reside in the community. Although most can live independently, some require supervised apartments where a staff member is present to ensure drug adherence. Programs provide a graded level of supervision in different residential settings, ranging from 24-hour support to periodic home visits. These programs help promote patient autonomy while providing sufficient care to minimize the likelihood of relapse and need for inpatient hospitalization. Assertive community treatment programs provide services in the patients home or other residence and are based on high staff-to-patient ratios treatment teams directly provide all or nearly all required treatment services.
Cognitive remediation therapy helps some patients. This therapy is designed to improve neurocognitive function and to help patients learn or relearn how to do tasks. This therapy may enable patients to function better.

Avolition And Drug Development
After two decades of psychotropic drug development with moderately superior tolerability profile over the previous drugs, the 2000s have been characterized by stagnation of productivity in psychiatric drug development,. The stagnation has been attributed to a lack of pathophysiological understanding of the mental disorders, difficulties in defining targets, poor translation from animal models to human, and the absence of biological markers. Adherence to diagnostic systems that were not specifically designed for drug development, such as the DSM, and the use of overinclusive outcome measures and scales has also been suggested as a major reason for the failure to develop novel psychotropics,,.
Indeed, it is accepted by academicians, clinicians, and regulators that the behavioral syndromes defined by DSM classifications and the assessment scales attempting to define the severity of these impairments do not correspond to specific, putative biological processes and brain abnormalities. Nevertheless, meeting criteria for the DSM classifications and manifesting a threshold level of severity still constitute the criteria for patients inclusion in trials and the basis for independent investigator-initiated studies and new drug applications.
Causes Of Positive Symptoms In Schizophrenia: Too Much Dopamine
There is no telling what causes schizophrenia in the first place, let alone the positive symptoms. Most researchers hypothesize that the positive symptoms are closely linked to increases in dopamine activity. In other words, the brain gets flooded with abnormally high amounts of dopamine and it causes the person to experience hallucinations, paranoia, and delusions.
Some researchers believe that dopamine systems in the mesolimbic pathway are what leads to positive symptoms. The main support for the theory that too much dopamine causes positive symptoms is antipsychotic medications. These medications used to treat positive symptoms work by blocking dopamine receptors and people experience a reduction in hallucinations, delusions, and other positive symptoms.
Additionally, the antipsychotic medications do not really help with negative symptoms of the illness, which establishes a link between dopamine and the positive symptoms. Other evidence supporting the dopamine hypothesis is in regards to the fact that amphetamines and drugs that increase dopamine production yield schizophrenia-like symptoms and can lead to temporary psychosis.

Clinical Features And Diagnosis
The diagnosis of schizophrenia is made clinically, based on a typical combination of symptoms , in the absence of other psychiatric or medical conditions that would explain the symptoms . The exact number and combination of symptoms, as well as the required duration of symptoms to make a diagnosis of schizophrenia, differ depending on the classification system used . Making a diagnosis based on clinical symptomatology and course alone, without the help of genetic markers or biomarkers, can lead to different diagnoses over time .
Schizophrenia is a disorder with an onset in late adolescence or early adulthood. Most patients present with schizophrenia between 15 and 45 years of age. Onset during childhood or in late life is possible, but not common. Onset at the extremes of the age range show continuity with typical-onset schizophrenia, although the onset of psychosis after age 50 should raise suspicion for a secondary psychosis.
Delusions are false, nonculturally sanctioned beliefs that are held with great conviction, even in the face of overwhelming evidence to the contrary. Table 28-5 outlines common delusional themes. The delusional idea puts the patient at odds with his or her culture or subculture. The content of delusions can be nonbizarre or bizarre . By convention, bizarre delusions suggest schizophrenia and exclude delusional disorder.

What If I Am Not Happy With My Treatment
If you are not happy with your treatment you can:
- talk to your doctor about your treatment options,
- ask for a second opinion,
- get an advocate to help you speak to your doctor,
- contact Patient Advice and Liaison Service and see whether they can help, or
- make a complaint.
There is more information about these options below.
You should first speak to your doctor about your treatment. Explain why you are not happy with it. You could ask what other treatments you could try.
Tell your doctor if there is a type of treatment that you would like to try. Doctors should listen to your preference. If you are not given this treatment, ask your doctor to explain why it is not suitable for you.
A second opinion means that you would like a different doctor to give their opinion about what treatment you should have. You can also ask for a second opinion if you disagree with your diagnosis.
You dont have a right to a second opinion. But your doctor should listen to your reason for wanting a second opinion.

Furthermore, which would be considered a positive symptom of schizophrenia? Positive symptoms: Feelings or behaviors that are usually not present, such as: Believing that what other people are saying is not true Hearing, seeing, tasting, feeling, or smelling things that others do not experience
Regarding this, what are positive symptoms of schizophrenia quizlet?
Terms in this set
- Positive Symptoms. Include delusions, hallucinations, disorganized thought/speech, and disorganized or catatonic behavior.
Which environmental triggers will definitely result in schizophrenia?
Environmental exposures, including infections, nutritional deficits, and neurotoxins, are known causes of neuropsychiatric disorders, and are potent disruptors of brain development, which has been proposed to play a major role in the etiology of schizophrenia .
The Neurobiology Of Negative Symptoms
Negative symptoms of schizophrenia are likely to be the result of irregularities of distributed neural networks , as opposed to the disruption of any discrete region of the brain. Although several hypotheses may be implicated in the pathophysiology of schizophrenia and negative symptoms, the dopamine and glutamate hypotheses are among those that are best supported by current evidence. The dopaminergic hypothesis of schizophrenia proposes that positive symptoms are the result of hyperactivity of dopaminergic neurotransmission in limbic pathways, while negative symptoms, loss of motivation, and impairment in cognition are thought to arise from hypodopaminergic functioning in the frontal lobe and additional mesolimbic structures., However, recent imaging studies suggest that abnormal dopamine function in schizophrenia may be in the dorsal rather than in the limbic striatum.

Difference Between Positive And Negative Symptoms Of Schizophrenia
Among schizophrenias many types of symptomscognitive, neurological, behavioral, and emotionalare categories known as positive symptoms of schizophrenia and negative symptoms of schizophrenia. Most schizophrenia symptoms in the DSM-5 fall into these two categories, and its the positive symptoms and negative symptoms that are the defining features of the mental illness we call schizophrenia.
Schizophrenia is an illness of the brain with a whole constellation of characteristics. The symptoms represent a range of experiences someone living with this serious mental illness can face. Everyone will possess some combination of symptoms, but no one has all of them .
Disorganized Speech Or Behaviour
Examples of disorganized speech include:
- slipping off-topic
- going off on a tangent
- answering a question in a way that doesnt make sense to the other person
- talking about things that seemed unrelated to the conversation
Disorganized behaviour refers to behaviours that dont fit the situation difficulty in completing tasks or reaching a goal or catatonic behaviour .
Examples of disorganized behaviours include:
- wearing clothing that doesnt fit the weather
- displaying an inappropriate emotional response to the situation
- difficulty performing activities of daily living such as cooking or self-care
- not responding or reacting to their environment

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.
Iischizophrenia And Neurocognitive Impairment: A Challenge For Drug Development
The diagnosis of schizophrenia requires the presence of positive symptoms , negative symptoms , and social/occupational dysfunction over a period of time, as defined by the DSM . Dozens of studies have also identified neurocognitive impairment as a core component of the disorder, characterized by deficits in global cognition, problem solving, and learning and memory. Despite decades of clinical trials leading to the development of dozens of antipsychotics that can be effective in treating positive and negative symptoms, there is little evidence that these agents can modulate neurocognitive impairment in an enduring, meaningful way. This limitation presents a significant obstacle for treatment as neurocognitive impairment in schizophrenia is linked to functional disability and poor outcomes. Fortunately, many groups have identified and validated neurophysiological biomarkers, discussed in the succeeding text, which show great promise in aiding development of procognitive agents aimed at targeting neurocognitive impairment in schizophrenia.

How Is Schizophrenia Diagnosed
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:
- 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.

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.
Individual Therapy for Treating Schizophrenia: Regular psychotherapy can normalize thought patterns in a schizophrenic patient to a great extent. Individual therapy also includes teaching the patients on how to identify warning signs of a schizophrenia relapse, cope up with stress. It also helps the individuals to be able to manage their illness overall.
