“…The results of recent systematic studies suggest that among the most common signs and symptoms during the prepsychotic phase of schizophrenia spectrum disorders are sleep disturbance, anxiety, anger/ irritability, depressed mood, deterioration in functioning, social withdrawal, poor concentration, suspiciousness, loss of motivation and drive, and low energy (An der Heiden and Hafner, 2000;Gourzis et al, 2002;Tan and Ang, 2001;Yung and McGorry, 1996b).…”

The frequency of various early signs of illness was examined in 96 first-episode patients suffering from schizophrenia, schizoaffective, or schizophreniform disorder. A factor analysis of these early signs was performed, and each of the five dimensions identified was examined for its relation to symptoms of psychosis at presentation and after 1 year of treatment. The results suggested five primary dimensions of early signs: emotional dysphoria and odd perceptual and cognitive content, impaired functioning, changes related to psychobiological or vegetative functioning, suspiciousness accompanied by difficulties in concentration, and irritability/aggression. Impaired functioning in the prepsychosis period was associated with higher negative symptoms at presentation for treatment, and higher levels of psychobiological changes were associated with lower positive symptoms of psychosis after a year of treatment. The latter findings may indicate that patients with more profound indications of affective disturbance or stress have a better prognosis.

BackgroundThere is a large literature suggesting that noise can be detrimental to health and numerous policy documents have promoted noise abatement in clinical settings. ObjectivesThis paper documents the role of noise in clinical environments and its deleterious effects with a particular focus on mental health care. Our intention however, is to go beyond the notion that noise is simply undesirable and examine the extent to which researchers have explored the meaning of sound in hospital settings and identify new opportunities for research and practice. Data sources and review methodsThis is a narrative review which has grouped the literature and issues in the field into themes concerning the general issues of noise in health care; sleep noise and hospital environments; noise in intensive care units; implications for service users and staff; and suggestions for new ways of conceptualising and researching clinical soundscapes. Data sources comprised relevant UK policy documents and the results of a literature search of Pubmed, Scopus and Web of Knowledge using terms such as noise, health, hospital, soundscape and relevant additional terms derived from the papers retrieved. In addition the references of retrieved articles were scanned for additional relevant material and historical items significant in shaping the field. ResultsExcess unwanted noise can clearly be detrimental to health and impede recovery, and this is clearly recognised by policymakers especially in the UK context. We use the literature surveyed to argue that it is important also to see the noise in clinical environments in terms of the meaning it conveys and rather than merely containing unwanted sound, clinical environments have a 'soundscape'. This comprises noises which convey meaning, for example about the activities of other people, the rhythms of the day and the nature of the auditory community of the hospital. Unwanted sound may have unwanted effects, especially on those who are most vulnerable, yet this does not necessarily mean that silence is the better option.Page 2 Therefore it is our contention that it is important to begin thinking about the social functions of sound in the mental health environment. ConclusionsWhilst it can be stressful, sound can also be soothing, reassuring and a rich source of information about the environment as well. It may be used to secure a degree of privacy for oneself, to exclude others or as a source of solidarity among friends and colleagues. The challenge then is to understand the work that sound does in its ecological context in health care settings.

“…The prodromal symptoms may lead to disruptive or impulsive behaviors, aggression, or suicidality, and often may impair function socially and vocationally. Approximately 70% to 75% of individuals who develop schizophrenia report a decline in school function and social withdrawal as prodromal symptoms emerge and worsen [2,6]. Longitudinal studies find that individuals who later went on to develop schizophrenia performed at approximately the level of or slightly lower than their peers in grade school and middle school; however, by high school, performance significantly declined and was well below average [8••,9].…”

Evaluating and treating the prodromal stage of schizophrenia

Identification of a person in the prodromal stage of schizophrenia, before the onset of the first episode of psychosis, provides an opportunity for early, potentially preventative, interventions. Recent attempts to develop "at risk" or "prodromal syndrome" diagnostic criteria have proved to be successful at identifying individuals at high risk for psychosis. Preliminary investigations find that pharmacologic and psychotherapeutic interventions may reduce the risk of psychosis in "at risk" individuals, but until more is known, current treatment guidelines recommend close monitoring, therapeutic interventions that address identified problems, including supportive or cognitive therapies to reduce the functional consequences of the presenting symptoms, family interventions to reduce family distress and improve coping, and intervention with schools to decrease likelihood of school failure. Pharmacologic intervention targeting the prodromal symptoms is not recommended, given the uncertain riskbenefit ratio.
