What Are The Risk Factors

Positive and Negative Symptoms of Schizophrenia

Schizophrenia is a disease that is caused by a chemical imbalance in the brain. When levels of dopamine, a neurotransmitter, are increased in certain parts of the brain it can trigger psychosis. There are many possible causes, including family history and genetics.

  • Genetics. Schizophrenia isnt caused by just one genetic variation, but a complex interplay of genetics and environmental influences. Having a family history of psychosis greatly increases a persons risk of developing the disease.
  • Brain chemistry. Problems with certain brain chemicals, including the neurotransmitters dopamine and glutamate, may contribute to schizophrenia.
  • Substance use. Research has indicated that smoking marijuana increases the risk of psychotic incidents and ongoing psychotic experiences. The younger and more frequent the use, the greater the risk. Smoking marijuana can also lead to earlier onset schizophrenia. The use of mind-altering drugs during teen years and young adulthood can also increase the risk 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.

What Are The Different Types Of Schizophrenia

Steven Gans, MD, is board-certified in psychiatry and is an active supervisor, teacher, and mentor at Massachusetts General Hospital.

Schizophrenia is a chronic mental health condition that interferes with a person’s perception of reality. People with schizophrenia have difficulty with emotions, thinking rationally and clearly, and in interactions and relationships with others.

Verywell / Cindy Chung

Until the most recent version of the Diagnostic and Statistical Manual of Mental Disorders was published in 2013, schizophrenia was officially recognized as having five distinct subtypes.

Because the symptoms of these subtypes were not felt to be reliable or consistently valid, the American Psychiatric Association determined that having distinct subtypes hindered diagnosis and removed them when they published the DSM-5.

Although they are no longer used for diagnostic categorization, some mental health professionals still find these subtypes useful for understanding the ways in which schizophrenia can present. This nuanced understanding can help determine the best ways to approach treatment plans.

As we look at the different subtypes of schizophrenia, it is important to keep in mind that the symptoms of these subtypes overlap with other disorders, and that to be diagnosed with schizophrenia, a person must meet the criteria outlined in the DSM-5.

A Semantic Memory Function In Schizophrenia

Perhaps the most influential theory of positive thought disorder in schizophrenia is that it stems from a faster and further automatic spread of activation through semantic memory . This theory assumes a model of semantic memory in which words and concepts are linked within a network according to their degree of association or co-occurrence . This theory has much intuitive appeal: a faster automatic spread of semantic associative activity could help explain the clinical phenomenon of loosening of association which, as discussed in section 1a, refers to the tendency of some patients to produce strings of semantically associated words that do not necessarily form a coherent whole.

B Working Memory And Executive Function Language And Schizophrenia

Numerous studies indicate that schizophrenia patients show deficits across multiple domains of cognitive function. Most of this work has focused on patients working memory and executive function. Patients show clear working memory deficits and also perform poorly on a variety of executive function tasks, such as the Wisconsin Card Sort Task and the Stroop, assessed as part of neuropsychological batteries. There has been some work examining the relationship between language dysfunction and executive or working memory dysfunction as assessed using neuropsychological measures. Severity of positive thought disorder in schizophrenia correlates with performance on several cognitive tasks, including the Stroop, continuous performance tasks and others . In a meta-analysis, reported a strong association between thought disorders and impaired executive functioning.

The referential communication impairments described in section 1b also correlate with patients poor performance on some of these neuropsychological measures. Studies by Docherty and colleagues have demonstrated correlations between referential communication disturbances and poor performance on tasks of immediate auditory memory and distractibility, working memory, sustained attention and sequencing . Interestingly, performance on sustained attention and sequencing tasks appears to be a better predictor of referential communication failures than positive thought disorder itself.

What Are Schizophrenic Episodes Like

Schizophrenia involves a psychosis, a type of mental illness in which a person can’t tell what’s real from what’s imagined. At times, people with psychotic disorders lose touch with reality. The world may seem like a jumble of confusing thoughts, images, and sounds. Their behavior may be very strange and even shocking.

Early Warning Signs Of Schizophrenia

In some people, schizophrenia appears suddenly and without warning. But for most, it comes on slowly, with subtle warning signs and a gradual decline in functioning, long before the first severe episode. Often, friends or family members will know early on that something is wrong, without knowing exactly what.

In this early phase of schizophrenia, you may seem eccentric, unmotivated, emotionless, and reclusive to others. You may start to isolate yourself, begin neglecting your appearance, say peculiar things, and show a general indifference to life. You may abandon hobbies and activities, and your performance at work or school can deteriorate.

A Clinical Characterizations Of Language Output In Schizophrenia

An impairment of verbal communication is one of several diagnostic features of schizophrenia. However, not all patients with schizophrenia show such abnormalities. Patients who do show verbal communication impairments are said to be thought disordered, reflecting the original perspective of psychopathologists who assumed that they reflected underlying disorders of thinking rather than primary disturbances of language . Today, however, the term thought disorder is used purely descriptively and refers to a variety of phenomena that result in an impairment of verbal communication. Thought disorder is assessed primarily through examining patients language output without any theoretical assumptions about its underlying causes. These phenomena are known to contribute to social and vocational dysfunction .

In addition to phenomena at the level of sentences and discourse, positive thought disorder can sometimes include abnormalities at the level of single words. For example, some patients produce neologisms or non-words, e.g. I got so angry I picked up a dish and threw it at the geshinker or So I sort of bawked the whole thing up . Others may use common words in an idiosyncratic or bizarre manner , e.g. a ballpoint pen referred to as paperskate or a watch referred to as a time vessel .

Changes In Behaviour And Thoughts

Some people feel their body is being taken over and someone else is directing their movements and actions.

Negative Symptoms: Affective Flattening Alogia And Avolition

Depression vs. Negative Symptoms of Schizophrenia – How To Tell The Difference

“Affect” refers to emotional expression. Affective flattening, distinguished by a restricted range of expressed emotions, is a fairly common negative symptom among some schizophrenia patients. Patients with affective flattening show relatively immobile and unresponsive facial expressions, often accompanied by poor eye contact and little body language or movement.

Alogia refers to difficulty with speaking. In some schizophrenic patients, alogia manifests as reduced total speech output, and reduced verbal fluency . Patients displaying alogia struggle to give brief answers to questions, for example.

Avolition describes a loss of motivation the will or desire to participate in activities or to do things. Some schizophrenic patients show avolition in that they will sit still for long periods of time, seemingly indifferent to their surroundings, and without displaying any interest in work or social activities. In extreme cases, this behavior becomes catatonia .

Symptoms Of Disorganized Schizophrenia:

Disorganized SpeechSchizophrenia can cause people to have difficulty concentrating and maintaining a train of thought, which manifests in the way they speak. People with disorganized speech might speak incoherently, respond to questions with unrelated answers, say illogical things, or shift topics frequently. Signs of disorganized speech involve the following:

  • Loose associations: Rapidly shifting between topics with no connections between topics
  • Perseveration: Repeating the same things over and over again
  • Made up words that only have meaning to the speaker
  • Use of rhyming words without meaning
  • When cognitive disorganization is severe, it can be nearly impossible to understand what the person is saying.

Disorganized BehaviorSchizophrenia negatively impacts goal-directed behavior. A person with disorganized schizophrenia is likely to have difficulty beginning a specific task or difficulty finishing a task. Independent functioning is exceptionally difficult due to this gross disorganization.

Disorganized behavior can manifest as the following:

  • A decline in overall daily functioning
  • Unpredictable or inappropriate emotional responses
  • Lack of impulse control
  • Behaviors that appear bizarre or lack purpose
  • Routine behaviors such as bathing, dressing, or brushing teeth can be severely impaired or lost.
