Can Post Traumatic Stress Disorder Lead To Schizophrenia

  • 2021-10-20T22:49:11+00:00Added an answer on October 20, 2021 at 10:49 pmPTSD is a mental disorder triggered in people who have either witnessed or experienced a life-threatening event, in which they feel intense fear, helplessness or horror. It is also referred to as post-traumatic stress disorder . The person who is suffering from PTSD may experience several symptoms, including flashbacks, nightmares, severe anxiety, anger, aggression, sleep disturbances etc. that result in significant impairment of daily functioning. However, PTSD can also occur without that exposure to trauma, for instance, in some individuals with a pre-existing psychiatric disorder, after exposure to the traumatic events of others, or even in healthy individuals exposed to elements resembling trauma. Traumatic stress disorder is not uncommon in soldiers after exposure to combat situations. It is estimated that up to ten per cent of soldiers who fought in Iraq and Afghanistan war suffer from PTSD.
  • 2021-10-10T21:49:22+00:00Added an answer on October 10, 2021 at 9:49 pmIt has been seen that those people who have been affected from PTSD can develop symptoms of schizophrenia. And the symptoms of PTSD include feeling the fear and a sense of a threat. These symptoms can continue for a long time and can lead to a person developing symptoms of schizophrenia.
  • Cognition And Mood Symptoms Include:

    • Trouble remembering key features of the traumatic event
    • Negative thoughts about oneself or the world
    • Distorted feelings like guilt or blame
    • Loss of interest in enjoyable activities

    Cognition and mood symptoms can begin or worsen after the traumatic event, but are not due to injury or substance use. These symptoms can make the person feel alienated or detached from friends or family members.

    It is natural to have some of these symptoms for a few weeks after a dangerous event. When the symptoms last more than a month, seriously affect ones ability to function, and are not due to substance use, medical illness, or anything except the event itself, they might be PTSD. Some people with PTSD dont show any symptoms for weeks or months. PTSD is often accompanied by depression, substance abuse, or one or more of the other anxiety disorders.

    Childhood Trauma Linked To Schizophrenia

    University of Liverpool
    Researchers have found that children who have experienced severe trauma are three times as likely to develop schizophrenia in later life.

    Researchers at the University have found that children who experience severe trauma are three times as likely to develop schizophrenia in later life.

    The findings shed new light on the debate about the importance of genetic and environmental triggers of psychotic disorders. For many years research in mental health has focused on the biological factors behind conditions such as schizophrenia, bipolar disorder and psychotic depression, but there is now increasing evidence to suggest these conditions cannot be fully understood without first looking at the life experiences of individual patients.

    The research, conducted by teams at Liverpool and Maastricht University in the Netherlands, is the first of its kind to bring together and analyse the findings from more than 30 years of studies looking at the association between childhood trauma and the development of psychosis. The researchers looked at more than 27,000 research papers to extract data from three types of studies those addressing the progress of children known to have experienced adversity studies of randomly selected members of the population and research on psychotic patients who were asked about their early childhood.

    Mental health experts describe post-traumatic stress disorder as consisting of four clusters of symptoms: re-experiencing symptoms, avoidance symptoms, negative changes in mood and brain function, and hyperarousal symptoms.

    However, some mental health professionals believe that the experience of psychotic symptoms should be considered as an addition to that list. Symptoms of psychosis, such as hallucinations, often occur with symptoms of PTSD.

    Trauma And Ptsd In Severe Mental Illness

    Trauma and posttraumatic stress disorder have high prevalence among individuals with severe mental illness, such as schizophrenia. Between 69.5 and 98% of this population experienced a traumatic event in their life , compared to 3956% in the general population . Rates of current PTSD in individuals with a severe mental illness range from 29 to 48% . Rates of current PTSD in studies focusing on schizophrenia specifically found 13, 28 and 29% . These rates are much higher than the prevalence of lifetime PTSD in the general population which ranges from 7.8 to 9.2% and the point prevalence of 2% .

    Although trauma and PTSD are common among individuals with a severe mental illness, clinicians frequently overlook trauma and PTSD. A recent study by Howgego et al. found that 33% of their sample of patients of a community mental health setting with a severe mental illness met the diagnostic criteria for PTSD. Only 4% of the sample had a formal diagnosis of PTSD in their medical record. The general lack of recognition and documentation of trauma and PTSD has been demonstrated in a number of studies .

    The Relationship Between Ptsd And Schizophrenia

    Post-traumatic stress disorder and symptoms of psychosis often occur together. PTSD is described in four clusters. These include avoidance symptoms, re-experiencing symptoms, hyperarousal symptoms, and negative changes in mood and brain function.

    Schizophrenia is considered one of the most common psychiatric diagnoses, and its not surprising for people to have both PTSD and schizophrenia. As weve discussed above, PTSD occurs after traumatic experience happen. Still, it has been found that traumatic experiences are more likely to happen to those with schizophrenia than in the general population.

    A National Institutes of Health study found that there is a significant genetic overlap between PTSD and schizophrenia.

    Treatment for both disorders is imperative, but some physicians are apprehensive about using conventional approaches. When using exposure therapy for PTSD, it may not be the best approach for someone with schizophrenia because therapy will worsen symptoms of schizophrenia. Some evidence has shown that well-thought-out treatment may reduce PTSD symptoms.

    If you are struggling with a combination of the two, its crucial that you find a physician who specializes in both treatments. It will allow you to have a tailored experience that helps your specific needs.

    Disinhibited Social Engagement Disorder

    Disinhibited social engagement disorder occurs in children who have experienced severe social neglect or deprivation before the age of 2. Similar to reactive attachment disorder, it can occur when children lack the basic emotional needs for comfort, stimulation and affection, or when repeated changes in caregivers prevent them from forming stable attachments.

    Disinhibited social engagement disorder involves a child engaging in overly familiar or culturally inappropriate behavior with unfamiliar adults. For example, the child may be willing to go off with an unfamiliar adult with minimal or no hesitation. These behaviors cause problems in the childs ability to relate to adults and peers. Moving the child to a normal caregiving environment improves the symptoms. However, even after placement in a positive environment, some children continue to have symptoms through adolescence. Developmental delays, especially cognitive and language delays, may co-occur along with the disorder.

    The prevalence of disinhibited social engagement disorder is unknown, but it is thought to be rare. Most severely neglected children do not develop the disorder. Treatment involves the child and family working with a therapist to strengthen their relationship.

    Editorial on the Research Topic

    Exposure to psychologically traumatic experiences has been part of the human condition throughout history, but only within the last half century has research provided insight into the short- and long-term sequelae of trauma, ultimately resulting in the creation of a specific diagnostic category to capture the most common negative consequences. In 1980, posttraumatic stress disorder was included in the Diagnostic and Statistical Manual of Mental Disorders , setting the stage for research and clinical practice to more systematically study and treat this mental health problem. Since the inclusion of PTSD in DSM-III, there has been huge growth in the fields understanding of PTSD, and the development of concomitant evidence-based treatments to aid individuals with PTSD in overcoming this disorder and returning to previous levels of functioning.

    Arousal And Reactivity Symptoms Include:

    • Being easily startled
    • Feeling tense or on edge
    • Having difficulty sleeping
    • Having angry outbursts

    Arousal symptoms are usually constant, instead of being triggered by things that remind one of the traumatic events. These symptoms can make the person feel stressed and angry. They may make it hard to do daily tasks, such as sleeping, eating, or concentrating.

    This Is How Trauma Leads to PTSD

    Researchers at the University of Manitoba, Columbia University, and the University of Regina examined data on 5,877 people from across the United States with the goal of determining the rates with which people with PTSD experience different psychotic symptoms.

    The researchers found that the experience of positive psychotic symptoms was most common among people with PTSD. Approximately 52% of people who reported having PTSD at some point in their lifetime also reported experiencing a positive psychotic symptom.

    Paranoia Hallucinations And Delusions

    Persons with PTSD may experience one or more of these symptoms, depending on the severity of their trauma exposure.


    Paranoia can cause an individual to lose trust in others and withdrawal socially, which can have a circular effect on symptoms of PTSD. Paranoia can make reaching out to others difficult. You may constantly overanalyze the motivations of other people and question whether they are telling you the truth. Children who have experienced child abuse often develop this loss of trust in adults. Paranoia can damage relationships and cause you to become isolated.


    Perhaps the most common symptom of PTSD related to psychosis is hallucinations. You may feel like you are seeing people or hearing voices that aren’t there, but that are related to the trauma. Hallucinations can be correlated with, but are distinct from, flashbacks. These are episodes in which you feel like you’re reliving the trauma.

    Dissociation can also be related to these experiences, where you perceive a disconnect between yourself and the world around you.


    Paranoia can become severe enough to become full-blown delusions. Delusions are usually related to the trauma in some fashion and can keep a person feeling as though they can’t move on from the past. Delusions can be debilitating and difficult to let go of once they have become established.

    What Are The Symptoms Of Ptsd

    The main symptoms and behaviours associated with PTSD and complex PTSD include:

    • Reliving the experience through flashbacks, intrusive memories, or nightmares
    • Overwhelming emotions with the flashbacks, memories, or nightmares
    • Not being able to feel emotions or feeling numb
    • Dissociation, that can include disconnecting from yourself or other people
    • Avoidance. This could mean that you try to distract yourself from thinking about the trauma. Or you avoid people and situations that remind you of the trauma.

    Other symptoms and behaviours associated with PTSD and complex PTSD include:

    • Negative mood and thinking.

    You can also try self-help techniques.

    How can the NHS help me?

    • your physical needs,
    • your social needs, and
    • any risk to yourself or others.

    Your GP will be able to talk to you about treatment options and coping strategies. You’re likely to be offered treatment if you’ve had symptoms of PTSD for more than 4 weeks or your symptoms are severe.

    You can choose whether to have treatment and decide about the options your GP offers you. If youre unsure of anything, like the benefits of treatment, then ask your GP.
