[Article of Interest] High Deprivation, Population Density And Inequality Found To Increase Rates Of Schizophrenia
Article adapted by Medical News Today
Higher rates of schizophrenia in urban areas can be attributed to increased deprivation, increased population density and an increase in inequality within a neighbourhood, new research reveals. The research, led by the University of Cambridge in collaboration with Queen Mary University of London, was published in the journal Schizophrenia Bulletin.
Dr James Kirkbride, lead author of the study from the University of Cambridge, said: “Although we already know that schizophrenia tends to be elevated in more urban communities, it was unclear why. Our research suggests that more densely populated, more deprived and less equal communities experience higher rates of schizophrenia and other similar disorders. This is important because other research has shown that many health and social outcomes also tend to be optimal when societies are more equal.”
The scientists used data from a large population-based incidence study (the East London first-episode psychosis study directed by Professor Jeremy Coid at the East London NHS Foundation Trust and Queen Mary, University of London) conducted in three neighbouring inner city, ethnically diverse boroughs in East London: City & Hackney, Newham, and Tower Hamlets.
427 people aged 18-64 years old were included in the study, all of whom experienced a first episode of psychotic disorder in East London between 1996 and 2000. The researchers assessed their social environment through measures of the neighbourhood in which they lived at the time they first presented to mental health services because of a psychotic disorder. Using the 2001 census, they estimated the population aged 18-64 years old in each neighbourhood, and then compared the incidence rate between neighbourhoods.
The incidence of schizophrenia (and other similar disorders where hallucinations and delusions are the dominant feature) still showed variation between neighbourhoods after taking into account age, sex, ethnicity and social class. Three environmental factors predicted risk of schizophrenia - increased deprivation (which includes employment, income, education and crime) increased population density, and an increase in inequality (the gap between the rich and poor).
Results from the study suggested that a percentage point increase in either neighbourhood inequality or deprivation was associated with an increase in the incidence of schizophrenia and other similar disorders of around 4%.
Dr Kirkbride added: “Our research adds to a wider and growing body of evidence that inequality seems to be important in affecting many health outcomes, now possibly including serious mental illness. Our data seems to suggest that both absolute and relative levels of deprivation predict the incidence of schizophrenia.
"East London has changed substantially over recent years, not least because of the Olympic regeneration. It would be interesting to repeat this work in the region to see if the same patterns were found."
The study also found that risk of schizophrenia in some migrant groups might depend on the ethnic composition of their neighbourhood. For black African people, the study found that rates tended to be lower in neighbourhoods where there were a greater proportion of other people of the same background. By contrast, rates of schizophrenia were lower for the black Caribbean group when they lived in more ethnically-integrated neighbourhoods. These findings support the possibility that the socio-cultural composition of our environment could positively or negatively influence risk of schizophrenia and other similar disorders.
Dr John Williams, Head of Neuroscience and Mental Health at the Wellcome Trust said: “This research reminds us that we must understand the complex societal factors as well as the neural mechanisms that underpin the onset of mental illness, if we are to develop appropriate interventions.”
The creators of the Serious Mental Illness blog invite you to submit your visual art, photography, video work, music, poetry, collage, or short fiction to Art from the Edge.
Art from the Edge, a virtual gallery and resource center, is dedicated to art created in and about extreme mental states. It is an open and public world wide forum for artists to share their visual and written works and their personal stories with all those interested in the connection between creativity and “edge” states.
Much like art, which exists in a multitude of mediums and forms of expression, there are a plurality of “edge” states that inspire the artists who harbor them. For this reason, we leave the term completely open to our community’s interpretation, knowing from research and experience that this state could be driven by psychosis or trauma, or an altered state induced by drugs. It could be the offshoot of extreme depression or grief, or the aftermath of a spiritual or mystical state of consciousness.
Ultimately, we are interested in the artist’s individual experience and in his or her sense of what it is that drove the creative act.
[Article of Interest] Talk Therapy Touted as First-Line Treatment for Youth with Psychosis Risk
By Traci Pedersen
A small clinical trial led by an Australian researcher suggests that young people at very high risk for psychotic illness should engage in talk therapy as an initial treatment rather than take antipsychotic drugs.
Only about 36 percent of high-risk individuals will likely develop psychosis within three years, and many physicians are concerned about the prospect of treating everyone at risk with drugs, which come with side effects. Another concern is that individuals will carry the label of mental illness unnecessarily.
“This shows it’s quite safe and reasonably effective to offer supportive psychosocial care to these patients,” said study author Dr. Patrick McGorry. There is “no evidence to suggest that antipsychotic medications are needed in first-line” treatment, he said.
The trial included 115 patients of a clinic in Melbourne, Australia, for young people believed to be at “ultra-high risk” for a psychotic disorder such as schizophrenia. The study was open to people between the ages of 14 and 30 who met at least one of three criteria: having low-level psychotic symptoms, having had previous brief episodes of psychotic symptoms that went away on their own or having a close relative with a psychotic disorder along with low mental functioning during the past year.
The study compared three types of treatment: talk therapy focused on reducing depression symptoms and stress while building coping skills plus a low dose of the antipsychotic risperidone, or talk therapy plus a placebo pill or therapy emphasizing social and emotional support plus a placebo. The goal was to see how many patients in each group progressed to full-blown psychosis.
After a year, there was no notable difference between the groups, but about 37 percent of the patients dropped out of the study. McGorry, a professor at the Centre for Youth Mental Health at The University of Melbourne, said if the trial had included more people, significant differences between the groups might have come forth.
“The importance of detecting early signs and symptoms of a serious mental illness is not controversial,” said Matcheri Keshavan, M.D., a professor of psychiatry at Harvard Medical School. “But the best way of treating or preventing it remains controversial.”
The rates of going on to full-blown psychosis—which ranged from about 10 percent to about 22 percent—were lower in all three groups than in previous studies.
The reasons for this aren’t clear, but McGorry said it’s possible that more participants will develop psychosis after the 12-month study period ends. Many of the study participants were also taking antidepressants, which may have eased psychotic symptoms.
Also, as with many trials, most patients showed poor adherence to the medications used, which may have influenced the results, the authors note.
In a 2010 study, McGorry found that fish oil supplements might prevent psychosis in the same type of at-risk individuals. Going forward, “what is needed is some way of finding predictive biomarkers that can tell who might be at the highest risk,” said Keshavan. “We need to understand their brains.”
[Article of Interest] Is Facebook a Factor in Psychotic Symptoms?
By American Friends of Tel Aviv University
TAU researcher connects computer communications and psychosis
As Internet access becomes increasingly widespread, so do related psychopathologies such as Internet addiction and delusions related to the technology and to virtual relationships. Computer communications such as Facebook and chat groups are an important part of this story, says Dr. Uri Nitzan of Tel Aviv University’s Sackler Faculty of Medicine and the Shalvata Mental Health Care Center in a new paper published in the Israel Journal of Psychiatry and Related Sciences.
In his study, the researcher presented three in-depth case studies linking psychotic episodes to Internet communications from his own practice. According to Dr. Nitzan, patients shared some crucial characteristics, including loneliness or vulnerability due to the loss of or separation from a loved one, relative inexperience with technology, and no prior history of psychosis or substance abuse. In each case, a connection was found between the gradual development and exacerbation of psychotic symptoms, including delusions, anxiety, confusion, and intensified use of computer communications.
The good news is that all of the patients, who willingly sought out treatment on their own, were able to make a full recovery with proper treatment and care, Dr. Nitzan says.
Behind the screen
The Internet is a free and liberal space that many individuals use on a daily basis and a growing part of a normal social life. But while technologies such as Facebook have numerous advantages, some patients are harmed by these social networking sites, which can attract those who are lonely or vulnerable in their day-to-day lives or act as a platform for cyber-bullying and other predatory behavior.
All three of Dr. Nitzan’s patients sought refuge from a lonely situation and found solace in intense virtual relationships. Although these relationships were positive at first, they eventually led to feelings of hurt, betrayal, and invasion of privacy, reports Dr. Nitzan. “All of the patients developed psychotic symptoms related to the situation, including delusions regarding the person behind the screen and their connection through the computer,” he says. Two patients began to feel vulnerable as a result of sharing private information, and one even experienced tactile hallucinations, believing that the person beyond the screen was physically touching her.
Some of the problematic features of the Internet relate to issues of geographical and spatial distortion, the absence of non-verbal cues, and the tendency to idealize the person with whom someone is communicating, becoming intimate without ever meeting face-to-face. All of these factors can contribute to a patient’s break with reality, and the development of a psychotic state.
A changing social landscape
Dr. Nitzan and his colleagues plan to do more in-depth research on Facebook, studying the features and applications that have the potential to harm patients emotionally or permit patients to cause emotional harm to others. Some psychotic patients use the Internet to disturb people, abusing their ability to interact anonymously, he says.
Because social media are now such an important part of our culture, mental health professionals should not overlook their influence when speaking to patients, Dr. Nitzan counsels. “When you ask somebody about their social life, it’s very sensible to ask about Facebook and social networking habits, as well as Internet use. How people conduct themselves on the Internet is quite important to psychiatrists, who shouldn’t ignore this dimension of their patients’ behavior patterns.”
The discrimination and stigma associated with mental illnesses largely stem from the link between mental illness and violence in the minds of the general public, according to the U.S. Surgeon General (DHHS, 1999). The belief that persons with mental illness are dangerous is a significant factor in the development of stigma and discrimination (Corrigan, et al., 2002). The effects of stigma and discrimination are profound. The President’s New Freedom Commission on Mental Health found that, “Stigma leads others to avoid living, socializing, or working with, renting to, or employing people with mental disorders - especially severe disorders, such as schizophrenia. It leads to low self-esteem, isolation, and hopelessness. It deters the public from seeking and wanting to pay for care. Responding to stigma, people with mental health problems internalize public attitudes and become so embarrassed or ashamed that they often conceal symptoms and fail to seek treatment (New Freedom Commission, 2003).”
This link is often promoted by the entertainment and news media. For example, Mental Health America, (formerly the National Mental Health Association) reported that, according to a survey for the Screen Actors’ Guild, characters in prime time television portrayed as having a mental illness are depicted as the most dangerous of all demographic groups: 60 percent were shown to be involved in crime or violence. Also most news accounts portray people with mental illness as dangerous (Mental Health America, 1999). The vast majority of news stories on mental illness either focus on other negative characteristics related to people with the disorder (e.g., unpredictability and unsociability) or on medical treatments. Notably absent are positive stories that highlight recovery of many persons with even the most serious of mental illnesses (Wahl, et al., 2002). Inaccurate and stereotypical representations of mental illness also exist in other mass media, such as films, music, novels and cartoons (Wahl, 1995).
Most citizens believe persons with mental illnesses are dangerous. A longitudinal study of Americans’ attitudes on mental health between 1950 and 1996 found, “the proportion of Americans who describe mental illness in terms consistent with violent or dangerous behavior nearly doubled.” Also, the vast majority of Americans believe that persons with mental illnesses pose a threat for violence towards others and themselves (Pescosolido, et al., 1996, Pescosolido et al., 1999).
As a result, Americans are hesitant to interact with people who have mental illnesses. Thirty-eight percent are unwilling to be friends with someone having mental health difficulties; sixty-four percent do not want someone who has schizophrenia as a close co-worker, and more than sixty-eight percent are unwilling to have someone with depression marry into their family (Pescosolido, et al., 1996).
But, in truth, people have little reason for such fears. In reviewing the research on violence and mental illness, the Institute of Medicine concluded, “Although studies suggest a link between mental illnesses and violence, the contribution of people with mental illnesses to overall rates of violence is small,” and further, “the magnitude of the relationship is greatly exaggerated in the minds of the general population” (Institute of Medicine, 2006). For people with mental illnesses, violent behavior appears to be more common when there’s also the presence of other risk factors. These include substance abuse or dependence; a history of violence, juvenile detention, or physical abuse; and recent stressors such as being a crime victim, getting divorced, or losing a job (Elbogen and Johnson, 2009).
