symptoms of paranoid schizophrenia

Paranoid schizophrenia is a common subtype of schizophrenia. One of the common symptoms of paranoid schizophrenia is a delusion. In general, delusional thinking is common among schizophrenic people. Alongside paranoid thoughts persist. This makes it hard to distinguish it from everyday thoughts.

Paranoid schizophrenia is a brain disorder. American Psychological Association (APA) declared the following in 2013. It is considered paranoia as an active symptom of schizophrenia. Later modifications did not consider it as a separate disorder. The disorder is now known as schizophrenia.

However, the original term has been around for decades. This is why many people are not accustomed to the new term. Hence the terms are used interchangeably at times. Schizophrenia makes it hard to tell any difference. You won’t realize if it’s real or just your thoughts. This will affect the way you perceive the world. The significant changes in thoughts make it hard to stay in the real world.

The outlook of paranoid schizophrenia

Not every schizophrenic person develops paranoia. However, borderline and psychotic cases develop paranoia. It is necessary to observe early symptoms. This will help to seek better treatment. Therefore, it will help you lead a better life.

Schizophrenia is essentially a spectrum disorder. In simple terms, several conditions, symptoms, and traits are linked. Before 2013, paranoid schizophrenia was distinct. However, APA decided to get rid of confusion. The Diagnostic and Statistical Manual of Mental Disorders provides guidelines for experts. They termed paranoia as a symptom. Hence, it is no longer considered a form of schizophrenia.

Some reasons for its removal as a subtype are as follows. There were limited diagnostic criteria to confirm paranoid schizophrenia. The results showed not very reliable. Alongside, the validity of the diagnosis became poorer. Hence, paranoia is today known as just a symptom.

Hallucinations are certain sensations. They do not exist in real life. However, schizophrenic people do feel it most of the time. These experiences are not understandable to the average population. The person experiencing it may feel it’s vivid and real. At times it may feel urgent too.

However, it’s all in their mind. It is the manifestation of repressed thoughts. Usually, traumatic situations give rise to such hallucinations. About 70% of schizophrenic people experience hallucinations. Hallucinations can be of the following types.

Auditory hallucinations

This is the most common type of hallucination. Most schizophrenic people experience this hallucination. It involves hearing voices. Sometimes multiple voices are heard. Such people hear a lot of whispering and murmuring. The voices may be angry. Or the voices may be demanding at times. Such people report being controlled by voices. They act based on the voices.

The associations of words are pretty loose. Schizophrenic jump back and forth between unrelated topics. Hence the conversations seem confusing. Most of the times, it is illogical. The next sign to look out for is perseveration. These people may tend to things over and over again.

Certain words may be new to ordinary people. This neo-language is nothing but made-up words. Such words make sense to schizophrenic people. However, ordinary people won’t get what they say. Certain rhyming words may be used frequently. These words hardly have any meaning at all. At times, cognitive disorganization may be severe. In such cases, it is tough to interpret what they say.

Disorganized behaviour

Schizophrenic people have difficulty working. Any goal-directed behaviour is hindered. They are likely to have difficulty in beginning any work. Or they may find it impossible to complete any task. The disorganization is gross. Therefore, independent functioning is hindered as well.

Causes of paranoid schizophrenia


Genes are the most significant factor for paranoid schizophrenia. This may run in families. A sibling, relative, or close parent may have schizophrenia. In such a case, the disorder may pass on to a family member. However, other factors may add to it.

Genes in themselves won’t cause such levels of deterioration. Genes make the person more susceptible to schizophrenia. Several triggering factors may account for the formation of schizophrenia.

Changes in brain structure

The brain spaces are called ventricles. In schizophrenic people, such ventricles become larger. Usually, they are larger than usual. Some parts of the brain deal with memory. It is the medial temporal lobes. The lobes become smaller in people with paranoid schizophrenia. The brain cells reduce them.

The brain may lose several tissues over time. There is a grey matter in the brain. It acts as a connecting bridge t connect nerve cells. Schizophrenic people are found to have lesser than average grey matter.

Changes in brain chemicals

The chemicals are typically called neurotransmitters. These help control communications within the brain. Two such vital chemicals are glutamate and dopamine. Their main task is to carry messages to cells. It does so along brain pathways. These pathways control thinking, perception, and motivation.

In paranoid schizophrenia, dopamine is related to hallucinations

Delusions are also linked to dopamine release. Brain areas running on dopamine becomes rapid in schizophrenic people. The overactivity can be stopped using antipsychotic drugs.

Glutamate is another important neurotransmitter. It helps people to memories and learns new things. Besides, it tells what a brain part would do. The glum ate flow may lessen when conditions worsen. Hence chronic people have difficulty in memorizing things. Also, the train of thought is lost at this point.

Changes in the environment

Environmental triggers may also affect brain activity. This, in turn, may cause increased problems in schizophrenic people. Viral infections may affect your birth. Before your birth, these infections increase the chances of schizophrenic tendency—for instance, improper nutrition of the pregnant mother.

Certain mind-altering drugs may cause damage. They are psychoactive drugs. For example, methamphetamine and LSD. These psychoactive drugs may increase the chances of schizophrenic activity. People taking such medications can hallucinate ethyl may have delusional ideas. Or their train of thought may be out of context. The resulting emotions may be inappropriate. One may have difficulty thinking clearly.

Pregnancy or complication at birth

Complications at birth may cause the development of mental disorders. One such common disorder is paranoid schizophrenia. Certain common birth complications are as follows. It includes low birth weight. The baby may be infected during pregnancy. The oxygen level may down during labour. This condition is called asphyxia.

The mother may be diagnosed with premature labour. During pregnancy, a mother may be obese. It can be found through maternal obesity diagnosis. All these factors may give rise to specific mental health disorders.

Childhood trauma

Trauma is one of the major factors underlying schizophrenia. These people may have experienced abuse or neglect in childhood. Hence, the most common hallucinations are of abuse and neglect. Some children may experience the death of loved ones. Or they may be separated at birth.

Hence, they are devoid of parental affection. This leads to repressed feelings. Any trigger brings back the traumatic incidents. The result is the onset of schizophrenia or related disorders.

Treatment of paranoid schizophrenia


These are medications to treat schizophrenia. These antipsychotic drugs tame delusions and hallucinations. These can be in liquid, pill, or injection form. Antipsychotic shots are also available. This suits people who often forget to take medications.

The medications are provided on the following basis. The first factor is how well it counteracts the symptoms. The second factor is the cost. The third factor is the side effects that come with each dosage. The final factor is how often the medication should be taken.

The second type is called second-generation antipsychotics. They are atypical antipsychotic drugs. Some of the common medications are listed here. They are CariprazineIloperidoneClozapine, Lumateperone tosylate, Olanzapine, Lurasidone.


It virtually talks about therapy. It is a crucial part of the whole therapy procedure. This allows the doctor to know any symptoms prevailing in them. Some of the common forms of psychotherapy are-

Individual psychotherapy

Usually, sessions are held. Here the therapist takes over the case. The client is taught how to deal with their thoughts. This, in turn, affects their behaviours. The client learns more about heir illness. The effects are explained to them. This allows them to know the differences.

Hence, schizophrenic people can distinguish reality from fantasy. This may further help them to manage their daily lifestyle. Besides, it may help them to lead a better everyday life.

Cognitive Behavioural Therapy or CBT

This therapy aims at changing a person’s thought processes. The thinking perspectives may change. The therapist helps to deal with delusions. The hallucinatory voices or images are taken care of. Medications accompany the CBT sessions. This helps to know the triggering factors. Hence, one understands what causes such psychotic episodes. Next, therapists help to reduce such future triggers.

Cognitive Enhancement Therapy or CET

For paranoid schizophrenia, CET is one fine treatment. In medical terms, it is cognitive remediation. It allows patients to understand social cues. Besides, it helps to understand d any triggering factors. It also improves memory and attention. The ability to organize thoughts restores.

Now, these people can organize their thoughts better. It helps them to speak better. They can reason well. The responses become more prominent. The treatment may be computer-based. This trains the brain to be more organized. Or they may carry out group sessions.

Psychosocial therapy

The program is available for free.

Schizophrenia is prevalent during the career-building years. Hence rehabilitation programs may include the following. It may begin with job counseling. There can a support system aimed at problem-solving. Further, they also teach money management. Educating a schizophrenic person in these areas may shape them better. Hence paranoid schizophrenia can just be a phase of life.

This treatment goes out for a particular group. Some patients experience psychotic episodes for the first time. This treatment is dedicated to their welfare. It is a team approach. This involves psychological therapy. Alongside appropriate medications, continue.

Social and employment services are included here. Therefore, more family members must join the therapy sessions. The aim is to change the direction of illness. Eventually, the prognosis for the illness shifts. This helps to reduce the disease at the early stages. Treatment at early stages is extremely beneficial. These intensive treatments benefit in the long term. It prevents any further relapse.

Assertive community treatment

This therapy is specially called ACT therapy. It offers a particular type of service. They are entirely personalized. The main aim is to meet daily life challenges.
