What Are Schizophrenic Episodes Like
Schizophrenia involves a psychosis, a type of mental illness in which a person cant tell whats real from whats 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.
Positive And Negative Symptoms Of Schizophrenia
Schizophrenia is a relatively uncommon medical condition that affects as many as 0.64% of the population, with symptoms typically appearing in the late teens to the early 30s. The symptoms of schizophrenia can be significant and with life-altering consequences but they can also be effectively managed with the right therapeutic approach.
If you or a loved one have been diagnosed with schizophrenia, you may have heard the symptoms described as either positive or negative. That can be confusing because while the terms seem to denote good vs. bad, they actually mean something entirely different.
At The Marcann Group, located in Glendale and Phoenix, Arizona, our team helps people with schizophrenia understand their disease and find treatment solutions to manage the symptoms so they can lead healthier and happier lives. Heres what positive and negative symptoms mean and how treatment can help you take back control of your life.
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 .

Hallucinations A Positive Symptom Of Schizophrenia
Hallucinations as they relate to positive symptoms of schizophrenia are false perceptions that have no perceivable or identifiable cause. They may affect any of the senses, including touch, taste, sound, sight and smell. Most often, however, hallucinations tend to be auditory or visual.
Auditory hallucinations: refers to hearing voices or other sounds that are not present in reality. This positive symptom of schizophrenia can be potentially dangerous if voices heard inflict thoughts of self harm or harming others. Frequently, those suffering from auditory hallucinations can be found conversing with their hallucination and or referring to them openly. Those who exhibit auditory hallucinations will require frequent assessment to determine the content of these hallucinations to ensure safety of both the individual and others.
Visual hallucinations: are those seen and believed to be present by the individual. The individual with this positive symptom of schizophrenia may see or experience bodies of light, figures or individuals, ghosts and or other objects that are otherwise perceivably false in reality.
Tactile hallucinations: also known as somatic hallucinations, is the perception of something happening to or within the body that is not actually present or perceivable. A common tactile/somatic hallucination is feeling something crawling on or underneath the skin. Feeling electrical pulses or intimate working of internal organs is also another common theme.

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

Data Preprocessing And Meg Source Reconstruction
NeuroPycon , an open-source python pipeline, was used for the preprocessing and source-reconstruction analyses. First, the continuous raw data was down-sampled from 1200Hz to 600 Hz, and band-pass filtered between 0.1-150 Hz. Next, independent component analysis was used to remove artefacts from the MEG signal using MNE-python .
Changes In Behaviour And Thoughts
A persons behaviour may become more disorganised and unpredictable.
Some people describe their thoughts as being controlled by someone else, that their thoughts are not their own, or that thoughts have been planted in their mind by someone else.
Another feeling is that thoughts are disappearing, as though someone is removing them from their mind.
Some people feel their body is being taken over and someone else is directing their movements and actions.

Negative Symptoms Of Schizophrenia
The negative symptoms of schizophrenia can often appear several years before somebody experiences their first acute schizophrenic episode.
These initial negative symptoms are often referred to as the prodromal period of schizophrenia.
Symptoms during the prodromal period usually appear gradually and slowly get worse.
They include the person becoming more socially withdrawn and increasingly not caring about their appearance and personal hygiene.
It can be difficult to tell whether the symptoms are part of the development of schizophrenia or caused by something else.
Negative symptoms experienced by people living with schizophrenia include:
- losing interest and motivation in life and activities, including relationships and sex
- lack of concentration, not wanting to leave the house, and changes in sleeping patterns
- being less likely to initiate conversations and feeling uncomfortable with people, or feeling theres nothing to say
The negative symptoms of schizophrenia can often lead to relationship problems with friends and family as they can sometimes be mistaken for deliberate laziness or rudeness.
Negative Symptoms: Affective Flattening Alogia And Avolition
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 .
The symptoms of schizophrenia are usually classified into:
- positive symptoms any change in behaviour or thoughts, such as hallucinations or delusions
- negative symptoms where people appear to withdraw from the world around then, take no interest in everyday social interactions, and often appear emotionless and flat

Hallucinations Delusions Disorganized Thinking Movement Disorders
The typical positive symptoms of schizophrenia, such as hallucinatory experiences or fixed delusional beliefs, tend to be very upsetting and disruptivenot a positive experience at all for you or someone you care about who is experiencing them.
From the outside, a person with positive symptoms might seem distracted, as if they are listening to something .
So why are these types of symptoms called “positive”? Schizophrenia causes a surplusof mental experiences . For example, hallucinations, which are not part of the normal, day-to-day experience for most people, are classified as a positive symptom for people with schizophrenia.
The phrase “positive symptoms” refers to symptoms that are in excess or added to normal mental functioning.
While these symptoms can be scary and extremely debilitating, taking the time to understand them can help you better cope or help a loved one do so.
Positive Vs Negative Symptoms
Schizophrenia is characterized by several symptoms that include:
- Delusions, including feelings of paranoia
- Auditory and/or visual hallucinations
- Strange movements or unusual postures
- Inability to focus or process whats going on around you
- Lack of personal hygiene
- Apparent lack of emotion or inappropriate emotional reaction
Medically, these symptoms are divided into two groups: positive and negative symptoms.
As noted, the terms positive and negative might lead you to believe that theres an upside to having schizophrenia. Thats not what these names mean. Instead, positive symptoms include changes in thoughts and behaviors that happen after a person develops the condition, such as hallucinations or delusions.
Alternatively, negative symptoms include those that cause a person to withdraw from people around them, culminating in isolation. It also includes the emotionless, disinterested, or flat affect typically exhibited by people with 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 Negative Positive And Disorganized Symptoms Of Schizophrenia
Positive symptoms can be thought of as those symptoms that are in addition to what others without schizophrenia might experience. Positive symptoms include delusions and hallucinations. Delusions are strong beliefs that dont fit with the persons culture. These beliefs persist even if not true or logical. For example, a person may think that the FBI is spying on them or they may believe they are famous or that the radio is speaking directly to them. Hallucinations include perceiving things that others do not. This may include any of the five senses. For example, a person may perceive that they see something like a crowd of people or that they hear something like a voice.
Negative symptoms can be thought of as those symptoms that are a deficit to what others without schizophrenia might experience. Negative symptoms include decreased thought and speech productivity , loss of ability to experience pleasure , decreased initiation of goal-directed behavior , and speech with little or no change to their tone, little or no change in their facial expression, even if they are talking about something upsetting or exciting . The person may have trouble starting tasks or sustaining activities over a period of time.

Psychotic Manifestations Beyond Psychotic Disorders
It is generally acknowledged that psychotic phenomena do not occur on an all-or-nothing basis. They are expressed in the population in a continuum of varying degrees of intensity and severity, ranging from normality to full-blown psychotic disorders. A meta-analytic study reported a median prevalence of 58% of psychotic experiences in the general population, while only 3% of individuals had a psychotic disorder diagnosis . Hence, psychotic symptoms are ubiquitously distributed in the general population, not being restricted to the psychosis disorders diagnoses, and not being restricted even to psychiatric diagnoses at large.
Concerning the first issue, previous studies reported on the presence of psychotic symptoms in several psychiatric disorders . In Alzheimers disease, psychotic symptoms are regarded as markers of poor prognosis, being associated with more rapid cognitive decline, more severe cognitive impairment , institutionalization, and mortality . Psychotic symptoms are usually related to low functioning and disability and worse cognitive performance in bipolar disorder patients . Psychotic phenomena were also found to occur in major depressive disorders and anxiety disorders , being related to a more severe condition in such cases . Obsessivecompulsive disorder cases with psychotic features have more often a deteriorative course compared to those without psychotic features .

Why Are They Called Positive Symptoms In Schizophrenia
The positive symptoms are so called because they are thinking or behaviour that the person with schizophrenia did not have before they became ill and so can be thought of as being added to their psyche. Positive symptoms include hallucinations such as hearing voices and delusions such as paranoid thoughts.

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.

Disorganized Thought & Behavior
The other aspect pertaining to positive symptoms of schizophrenia refers to the thoughts and behaviors, which become evident when talking with or observing someone with this mental illness.
Disorganized thought: ones speech may appear to be jump around from topic to topic, without any relevant or significant connection. This is known as tangential thought processes. In the middle of a conversation, the individual may suddenly stop in the middle of a sentence, and not be able to continue on with that train of thought. This is otherwise known as thought blocking. Other characteristics of disorganized thoughts may include bouts of incomprehensible made up words that only make sense to the individual, mimicking the speech of another person, rhyming conversations and or repetitive speech.
Disorganized behavior: refers to the inability to meaningfully take care and due attention of everyday aspects of life. This includes basic grooming and hygiene practices, as well as acting in accordance to societal cultures and norms. Frequent inappropriate outbursts or odd behaviors such as heavily applied makeup, wearing a swimsuit outdoors during winter, are some examples of disorganized behavior that may exist as part of the positive symptoms of schizophrenia.
