What Percent Of The World Population Has Schizophrenia

Don't Miss

Schizophrenia Statistics In The United States

These Are the Potential Causes of Schizophrenia
  • The prevalence of schizophrenia among U.S adults is estimated to be 1.5 million people per year.
  • Schizophrenia is often diagnosed in young people during their late teens to early 30s with symptoms commonly presenting earlier in males than in females.
  • The average life lost for individuals with schizophrenia in the U.S. is 28.5 years.

Other Causes Of Schizophrenia

Along with genetics, other potential causes of schizophrenia include:

  • The environment. Being exposed to viruses or toxins, or experiencing malnutrition before birth, can increase the risk of schizophrenia.
  • Brain chemistry. Issues with brain chemicals, such as the neurotransmitters dopamine and glutamate, may contribute to schizophrenia.
  • Substance use. Teen and young adult use of mind-altering drugs may increase the risk of schizophrenia.
  • Immune system activation. Schizophrenia can also be connected to autoimmune diseases or inflammation.

The Effects Of Stress

Many psychiatric disorders, including schizophrenia, are associated with disturbances of the bodys stress responses. This is reflected in levels of cortisol, which is a steroid hormone thats produced by the adrenal gland in stressful situations.

Chronic production of high levels of cortisol has a damaging effect on virtually all body systems, including the brain.

It is possible, and even probable, that belonging to a small migrant group is associated with a state of chronic stress, producing increased baseline cortisol and therefore increased risk of schizophrenia.

There are reasons to believe that this kind of stress effect is more powerful in urban areas, because city living affects the brains response to stress. Baseline levels of crime, social fragmentation and urban decay are also important.

This model, linking community factors with effects on individual brains, receives strong support in a study by Duke University and Kings College London, published in Schizophrenia Bulletin in May in 2016.

The team analysed data from over 2,000 UK-born twins and found that reduced social cohesion and crime victimisation likely explain, at least in part, why children in cities have an increased risk of developing symptoms of disorders such as schizophrenia. It is not the cities themselves, then, but the way we live in them that likely matters most.

Skip Spence 1946 1999

Musician and Singer Songwriter

Age of Diagnosis: 23

Individual History: Alexander Lee Skip Spence was a Canadian-born American musician and singer-songwriter. He began his career as a guitarist in an early line-up of Quicksilver Messenger Service, and was the drummer on Jefferson Airplanes debut album, Jefferson Airplane Takes Off. He was one of the co-founders of Moby Grape, and played guitar with the group until 1969. He released one solo album, Oar, and then withdrew from the music industry. His career was plagued by drug addiction and mental health problems. In the late 1960s, Spence became delusional after taking too much acid. He was found marching around his hotel room with an axe, bashing down doors and claiming he was the anti-Christ. At that point he was taken to Bellvue Hospital where he was formally diagnosed as schizophrenic. Spence died in 1999 from lung cancer, two days before his 53rd birthday.

Things You May Not Have Known About Schizophrenia

Santa Barbara Mental Health Descriptions and Statistics Guide

Schizophrenia is a mental health condition that people are willing to talk about these days. If you or someone you know has schizophrenia, read our list of 10 things you may not have known before!

  • About 7 or 8 out of every 1,000 individuals will have schizophrenia in their lifetime
  • Though the disease itself is not that common, it can affect people of every gender, race and ethnicity. Slightly more men than women will develop schizophrenia.

  • Schizophrenia usually presents itself during adolescence or young adulthood
  • It remains hidden during childhood and develops between the ages of 16 and 30. A number of factors, including isolating oneself and withdrawing from others, an increase in unusual thoughts and suspicions, and a family history of psychosis, can predict the onset of schizophrenia. Schizophrenia hits when young adults are starting their life, said Andrew Cutler, MD, of Meridien Research. Imagine the effect it has on them. And its horrible for families to go through.

  • You have a greater chance of developing schizophrenia if a family member has it
  • It is well known among scientists that schizophrenia can run in families. About 10 percent of people who have a first-degree relative, like a parent or sibling, with the disorder will develop it themselves. However, as there are many people with schizophrenia who do not have relatives with the condition, genetics is just one factor that causes schizophrenia.

  • Schizophrenia is caused by a number of genes, not just one

    How Does Schizophrenia Rank In Prevalence With Other Mental Disorders

    According to estimates from Johns Hopkins, about 26 percent of Americans who are 18 or over will suffer from a diagnosable mental disorder in a single year. Some people may even suffer from more than one mental or mood disorder at a time. To put U.S. schizophrenia statistics in context with other mental health conditions, consider these numbers:

    • 1.1 percent of American adults have been diagnosed with schizophrenia
    • 18.1 percent of American adults have been diagnosed with an anxiety disorder
    • 6.9 percent of the U.S. adult population has been diagnosed with major depression
    • 2.6 percent of American adults are living with bipolar disorder

    Taken together, more than 46 million Americans will experience a mental health disorder in a given year.

    Life Satisfaction And Mental Health

    Is the prevalence of mental health disorders reflected in self-reported life satisfaction or happiness? Overall, evidence suggests that there is a negative correlation between prevalence of particular mental health disorders and self-reported life satisfaction. This suggests that life satisfaction and happiness tends to be lower in individuals experiencing particular mental health disorders.

    We discuss the link and evidence for this relationship in our entry on Happiness and Life Satisfaction.

    How Many People Have Schizophrenia

    Schizophrenia is a type of severe mental disorder that can disrupt a person’s sense of self, perception, and language. In many cases, it also includes delusions, hearing voices, or other psychotic experiences. Schizophrenia can also hinder a person’s ability to function by disrupting their studies or causing them to lose the skill that helped them make a living. Today, there are many effective treatments available, letting those with the condition live productive lives where they are fully integrated into society.

    The Facts About Schizophrenia Demographics

    The Human Social Brain: How It Goes Awry in Schizophrenia
    • Schizophrenia affects men and women equally.
    • Every ethnic group in the world is affected by schizophrenia at the same 1% rate in all circumstances.
    • Most symptoms, including delusions and hallucinations, begin between the ages of 16-30.
    • It is very rare for someone above the age of 45 to develop symptoms that can lead to a clinical diagnosis of schizophrenia.
    • The cost of treating schizophrenia in the United States was $62.7 billion in 2002. More money is spent on long-term care than is spent on outpatient care.
    • People who are at the greatest risk of developing schizophrenia are those who have an identical twin who has been diagnosed with this mental disorder.

    Although both genders and all ethnicities are equally affected by schizophrenia, there are some unique issues that can affect certain segments of the population. Men tend to develop the symptoms of schizophrenia earlier than women do. The average age of onset in men is 18, but in women the average age of onset is 25. Overall this means about 1 person out of every 4,000 will be diagnosed with this mental disorder over any given year.

    Defining The Prevalence Of The Disease

    The prevalence rates of schizophrenia depend upon a whole range of factors, such as the availability of and response to treatment. The prevalence of schizophrenia, as with other mental disorders, can be calculated from a number of sourcesfrom case registers to field surveys. The latter lend themselves more readily to estimation of period prevalence than point prevalence, while case register data can provide point prevalence more readily. The denominator can be the whole population or only a small defined population.

    Saha et al. quite rightly differentiate between traditional prevalence, or core, studies , and studies in specific sub-groups . Using sequential filters they were able to isolate discrete data from multiple studies, and they used other strategies to ensure that the largest groups were counted.

    The authors had hypothesised that prevalence estimates would differ between lifetime, period, and point prevalence and that lifetime prevalence would be higher than lifetime estimates . They also predicted that the estimates would be higher for males, those from urban areas, and migrants. Case ascertainment methods and sample selection do influence prevalence rates, so Saha et al. chose studies that used comprehensive case ascertainment methods.

    Social Isolation A Major Problem

    While these psychotic symptoms are more alarming, other symptoms reinforce the alienation of people with schizophrenia. They are often unable to participate in normal social events or conversations, and lack sufficient motivation for simple activities like bathing or cooking. In addition, sufferers lack the insight to recognise how their inappropriate behaviour appears to others.

    A Future After Schizophrenia

    • 1 out of every 4 people who are diagnosed with schizophrenia will completely recover within 10 years.
    • Another 1 out of every 4 people with schizophrenia are rated as being much improved and can live a mostly independent life.
    • Only 15% of those with schizophrenia will still be unimproved and hospitalized after 10 years from their first diagnosis.
    • About 1 out of 10 people diagnosed with schizophrenia will take their own lives within the first decade of their diagnosis.
    • When extended out to 30 years after first diagnosis, those who are greatly improved increases from 50% to 55%. Hospitalizations decrease by 5%, but suicides increase by 5%.
    • 6%. This is the percentage of people with schizophrenia who are homeless. Another 6% live in prison.

    Once a schizophrenia diagnosis is confirmed, only 28% of those with this diagnosis are able to live independently on their own. About 200k people with this mental disorder are homeless. More people are not being treated for their mental disorder than are being treated. 1 out of every 3 psychiatric hospital visits is because of schizophrenia and this accounts for 25% of all mental health costs. Estimates place a potential cure for this mental disorder being discovered within the next decade it cant come soon enough for the demographics of schizophrenia.

    Treatments And Risk Factors

    There are many pharmaceutical, psychological and social treatments for schizophrenia, and these help patients and families a great deal. It is critical that these treatments are delivered efficiently, effectively and with compassion, to heal and empower the mentally ill and their families.

    But these treatments are deeply imperfect and are not cures for schizophrenia.

    The prospects of better treatment would be much improved if we understood precisely what causes schizophrenia in the first place. But we do not.

    In the search for answers, it is critical to develop a better understanding of urbanicity and even more so its relationship with other risk factors, such as genes, prenatal or birth injury, psychological trauma, cannabis, head trauma, migration, social adversity, chronic stress and others.

    All are of these linked with schizophrenia to varying degrees, but none are fully understood.

    Ultimately, research is hampered by the fact that schizophrenia is defined by symptoms rather than biological tests. Schizophrenia, like fever or headaches, is almost certainly an umbrella term that covers a family of different but related sub-disorders, rather than a single, biologically distinct entity.

    These sub-disorders, despite sharing many symptoms, might well have somewhat different origins in different groups or individuals. As a result, schizophrenia retains the ultimate mystery that is intrinsic to all true scientific enigmas: it might not exist as a definable entity.

    Public Opinion / Perception Of Schizophrenia

    Worldwide, people diagnosed with schizophrenia face stigma and discrimination. The stigma associated with schizophrenia can delay a diagnosis as many people may hesitate to discuss their symptoms even with a healthcare provider. Although this stigma has been challenged in the U.S., it still exists in much of the rest of the world. Family members may attempt to keep the diagnosis of a loved ones schizophrenia secret. In developed nations like the U.S., however, a clearer understanding of the illness and its symptoms has reduced the stigma. Given the rate of homelessness among this population, however, more support must be allocated to this segment of the population.

    Depression Is Complicated This Is How Our Understanding Of The Condition Has Evolved Over Time

    People often think of depression as a single, uniform condition deep sadness and a loss of interest in the activities that someone usually enjoys. But depression is complicated and its difficult to define what it means in an objective way.

    This is because depression is a condition of the mind: it is diagnosed based on peoples psychological symptoms and behavior, not from a brain scan or markers in their blood or DNA.

    When we diagnose depression, we have to rely on people to recall their own symptoms. We have to trust that doctors will observe and probe their symptoms reliably. We have to analyze this information to understand what people with depression experience that other people dont.

    Our ability to do all of these things accurately has changed over time, and so has our understanding of depression.

    This comes down to three factors.

    First, many countries now screen for depression in the general population, not just in a subset of people who are seen by a small number of doctors. In many studies, researchers track patients over long periods of time to understand how the condition progresses.

    Second, we use questionnaires and interviews that treat depression as a condition that can occur at different levels and change with time.

    Third, we have better statistical tools to help us refine questionnaires and understand how symptoms are related to one another.
