Paranoid Schizophrenia: Causes, Symptoms and Treatments

The most common type of schizophrenia is paranoid schizophrenia. Paranoia was recognized as a positive symptom of schizophrenia by the American Psychiatric Association in 2013, rather than as a separate diagnosis.

This led to the name of the disorder being changed to simply “schizophrenia.” However, because paranoid type schizophrenia has been around for a long time, people are still familiar with it.

People who suffer from schizophrenia may have difficulty distinguishing reality from fantasy. A person’s perception of and response to the world can be profoundly affected by the symptoms.

Paranoia does not develop in all people with schizophrenia. Paranoia is, however, one of the most significant symptoms of schizophrenia. Early detection of its symptoms is crucial, and it can greatly improve your quality of life.

Paranoid schizophrenia symptoms

Symptoms of this condition can evolve and even improve over time. There is no guarantee that all people with schizophrenia will experience paranoia. The following symptoms may develop in some individuals:


A delusion is a strong false belief. It is important to understand that there are numerous types of delusions. Following are a few common types:

  • Delusions of control: Having thoughts that you are being controlled by an external authority, such as the government might lead to feeling uneasy.
  • Delusions of grandeur: Your faith in your abilities, wealth, or importance might lead you to believe you are exceptional.
  • Delusions of persecution: Essentially, you believe you are under attack by everyone (or perhaps just a single person).
  • Delusions of reference: Perhaps you thought that a seemingly insignificant item was meant for you.

Approximately 90 percent of individuals with schizophrenia suffer from delusions. Delusions differ from person to person.


You can have hallucinations when you perceive things that are real, but they do not exist. Those suffering from schizophrenia with paranoia experience hearing voices most frequently.

You may even recognize the voices as being those of people you know. Isolation from others can make symptoms worse.

Disorganized speech

Disorganized speech is also a symptom of schizophrenia. You may repeat words or phrases or change the subject mid-sentence. It is even possible to invent your own words. Concentration problems are a common symptom of schizophrenia.

This disorder causes disorganized speech that is different from speech impairment.

Disorganized behavior

When you behave in an unorganized manner, whether at work or home, you cannot control your behavior in any given situation. Some of these may be difficult for you:

  • Engaging in routine daily activities
  • Managing your impulses
  • Controlling your emotions
  • Behaving oddly or in an inappropriate way

A symptom like this can have a negative impact on your job, your personal life, and your social relationships.

Negative symptoms

A lack of negative symptoms means that a person does not exhibit the behaviors typically associated with schizophrenia. Positive symptoms are, for example:

  • The lack of desire to participate in activities that are viewed as fun is known as anhedonia
  • Lack of emotions
  • Blunted expression
  • The world is less interesting in general

Suicidal thoughts

Suicidal behavior and thoughts are also common symptoms of schizophrenia. When left untreated, they occur more frequently.

When someone close to you is thinking about suicide or self-harm, call the nearest emergency services immediately. It can connect you with someone who can help with your mental health.

Risk factors and causes

Paranoid schizophrenia has no known cause. There is a possibility that schizophrenia is genetic, as it runs in families.

Some people who have family members suffering from schizophrenia will not develop the disorder themselves. Some people with schizophrenia do not have paranoia symptoms.

The following factors also increase the risk:

  • Brain abnormalities
  • Childhood abuse
  • Low oxygen levels at birth
  • Separation or loss of a parent at a young age
  • Virus exposure during infancy or before birth

Diagnostic methods

Schizophrenia is diagnosed through a series of tests and evaluations. You will be examined by your doctor for:

  • Medical test results and blood work
  • History of health
  • Neuroimaging test results
  • Physical examination results

An evaluation by a psychiatrist may be recommended as well.

A diagnosis of this condition may be made if you’ve recently experienced two major symptoms. A severe case of these symptoms would interfere with daily life.

A combination of treatments is needed for long-term success. Medications and other forms of therapy are primarily involved here. When severe symptoms make your or others’ environment dangerous, you may need hospitalization.

Paranoid schizophrenia medications

Delusions and hallucinations can be alleviated by taking antipsychotic medications. Dopamine is controlled in the brain by these drugs.

Among the options are:

  • Chlorpromazine (Thorazine)
  • Fluphenazine (Modectate)
  • Haloperidol (Haldol)
  • Perphenazine (Trilafon)

Also, your doctor may recommend drugs that are less likely to cause side effects.

You may need to experiment with a few medications and dosages before you find the right one and the dosage that works best for you. As soon as you begin to feel better, your symptoms may decrease.

It may take up to three to six weeks to notice the full effect of the treatment. For some people, the effect of the medication takes about 12 weeks to fully manifest.

You may see continued improvement in your symptoms after taking some medications for a long time. You should discuss antipsychotics with your medical professional. It’s possible to experience side effects, such as:

Some medications may continue to work for months after you take them. Antipsychotics have pros and cons, so make sure you discuss them with your doctor. It’s possible to experience side effects, such as:

  • Dizziness
  • Drowsiness and fatigue
  • Dry mouth
  • Low blood pressure
  • Nausea
  • Vomiting
  • Uncontrollable movements
  • Vision changes
  • Weight gain

In some cases, your doctor may prescribe another medication to treat other symptoms. Anxiety-reducing drugs and antidepressants are possible options.


Psychosocial or group therapies can be used as treatment options. Group therapy is useful because you will be surrounded by others who experience the same thing. People with schizophrenia face isolation, and this community helps to build a sense of belonging.

Your daily life might be easier to handle if you use psychosocial therapies. In addition, to talk therapy, these methods can help you become more aware of how to deal with social situations. It is important to communicate warning signs to your loved ones and doctor as part of therapy sessions.


A diagnosis of schizophrenia with paranoia that is detected early may respond well to medication and therapy. It may be necessary for you to be hospitalized, however, if you could harm yourself or others.

Some people are hospitalized when they are no longer able to provide for their own needs for clothing, food, and shelter.

Possible complications

After schizophrenia treatment, some people may recover to a point where they have low symptoms or none at all. Treatment is needed for life to prevent various conditions related to the disorder, including:

When schizophrenia is untreated, it may become crippling. A person who does not seek treatment can end up homeless and unemployed in severe cases.

Coping strategies

You need to take care of yourself if you have paranoid schizophrenia. The following tips will help you:

  • Keep your stress levels under control. Stress and anxiety-provoking situations should be avoided. Spend some time relaxing for yourself. Take a walk, read, or meditate.
  • Take care of your diet. You can feel better and have more energy by eating plant-based foods and unpackaged items.
  • Regular exercise is important. Your brain releases more serotonin when you keep physically active.
  • Maintain social events. Your symptoms might be made worse by isolation if you don’t take part in social activities.
  • Make sure you get enough sleep. People with schizophrenia may experience hallucinations, delusions, and paranoia if they do not get enough sleep.
  • Smoking, drinking alcohol, and abusing drugs are unhealthy behaviors.

Advice for caregivers

Follow these tips to help someone you care for who has schizophrenia:

Assist with the treatment process. You may have to intervene on your loved one’s behalf once the symptoms have become so advanced. You should explain the situation to your doctor. Also, your doctor may want to know what happened with your loved one recently.

Maintain an appointment schedule. The affected individual may also have difficulty keeping up with appointments with doctors and therapists. It would be helpful if you added these appointments to your calendar as well. Please remind the patient and provide a ride if necessary.

Consider joining a support group. People suffering from paranoid schizophrenia tend to isolate themselves. Your loved one may not be social due to severe delusions caused by this disorder. It may be helpful to join a support group.

Recognize and accept their symptoms. No matter how unfamiliar the symptoms are to you, you need to acknowledge your loved one’s struggles. It is important to realize that symptoms you cannot see or feel are still very real for them. Making fun of or talking down to a loved one will only isolate them further.

Provide unconditional support and respect. Your greatest gift as a caregiver is to offer respect and support, regardless of your loved one’s situation. You should be aware that schizophrenia symptoms fluctuate. Successful treatment can also take time.
