For patients with psychiatric disorders, current diagnostic and treatment approaches are far from optimal. The clinical interview drives the standard approach—matching symptoms to diagnostic criteria—and results in standardized pharmacological and behavioral treatments, often, with inadequate outcome; but now, recent imaging advances can correlate behavioral assessments with brain function and measure them against normative databases to provide data critical for the reevaluation of patient diagnosis and treatment. This article addresses the data that support a redefinition of our current paradigm. We believe a neurobehavioral approach provides for more personalized treatment approaches unbound from classically defined diagnostic biases.

Circadian timekeeping can be reset by brief flashes of light using stimulation protocols thousands of times shorter than those previously assumed to be necessary for traditional phototherapy. These observations point to a future where flexible architectures of nanosecond-, microsecond-, and millisecond-scale light pulses are compiled to reprogram the brain’s internal clock when it has been altered by psychiatric illness or advanced age. In the current review, we present a chronology of seminal experiments that established the synchronizing influence of light on the human circadian system and the efficacy of prolonged bright-light exposure for reducing symptoms associated with seasonal affective disorder. We conclude with a discussion of the different ways that precision flashes could be parlayed during sleep to effect neuroadaptive changes in brain function. This article is a contribution to a special issue onCircadian Rhythms in Regulation of Brain Processes and Role in Psychiatric Disorderscurated by editors Shimon Amir, Karen Gamble, Oliver Stork, and Harry Pantazopoulos.

This paper reviews the development of diagnostic criteria for the psychiatric disorders in order to provide a model for the development of classification of headache. The strengths and weaknesses of the current psychiatric classification system, and procedures that have been instituted to strengthen the next version of the classification are described. The problems that characterized the successive versions of the criteria are highlighted in order to stimulate future developments of diagnostic criteria for headache syndromes. Recommendations for application of these principles to headache classification are presented.

Organic psychiatric disorders result from brain dys­function caused by organic pathology inside or outside the brain. Dementia is the most common condition, with Alzheimer’s disease alone affecting 1 per cent of the population at 60 years, rising to 40 per cent over 80 years. Many of the rarer organic psychiatric dis­orders tend to affect a wider age range, but present in similar ways. Given the changing demographics of most developed countries, disorders producing cognitive im­pairment in older adults are becoming increasingly important for provision of healthcare services and in daily clinical practice. This chapter will cover the more common causes of cognitive impairment, and there is additional information in Chapters 18 and 20 on psych­iatry of older adults in psychiatry and medicine. There are three common clinical presentations of or­ganic psychiatric disorders: … 1 Delirium— an acute generalized impairment of brain function, in which the most important feature is impairment of consciousness. The disturbance of brain function is generalized, and the primary cause is often outside the brain; for example, sepsis due to a urinary tract infection. 2 Dementia— chronic generalized impairment, in which the main clinical feature is global intellectual impairment. There are also changes in mood and behaviour. The brain dysfunction is generalized, and the primary cause is within the brain; for example, a degenerative condition such as Alzheimer’s disease. 3 Specific syndromes— which include disorders with a predominant impairment of isolated areas; for example, memory (amnesic syndrome), thought, mood, or personality change. These include neurological disorders that frequently result in organic psychological complications; for example, epilepsy…. Table 26.1 lists the main categories of psychiatric disorder associated with organic brain disease. The following sections describe these syndromes and the psychiatric consequences of a number of neurological conditions. Organic causes of other core psychiatric conditions (e.g. anxiety and psychosis) are covered in the relevant specific chapters. Delirium is characterized by an acute impairment of consciousness producing a generalized cognitive impairment. The word delirium is derived from the Latin, ‘lira’, which means to wander from the furrow. Delirium is a common condition, affecting up to 30 per cent of patients in general medical or surgical wards, with the primary cause often being a sys­temic illness. The term ‘acute confusional state’ is a synonym for delirium.

SummaryObjectives - To present the results obtained from a cross-sectional evaluation of a sample of primary care attenders selected in Verona in the framework of the World Health Organization International Multicentre Study on Psychological Problems in Primary Care Settings. Methods - Among consecutive attenders at 16 primary care clinics in Verona during the period April 1991/February 1992, a random sample, stratified on the basis of GHQ-12 scores, was selected for a thorough evaluation of psychological status, physical status and disability in occupational and other daily activities. All patients with psychopathological symptoms at baseline assessment and a 20% random sample of those without psychopathological symptoms were interviewed again after 3 and 12 months (data not presented here). Results - Overall, 1,656 subjects were approached at the primary care clinics and 1,625 met inclusion criteria. The screening procedure was completed by 1,558 subjects and the second-stage evaluation by 250. Psychiatric disorders according to ICD-10 criteria were diagnosed in 12.4% of consecutive primary care attenders; of these, about one-third (4.5% of consecutive primary care attenders) satisfied ICD-10 diagnostic criteria for two or more disorders. Current Depressive Episode (4.7%) and Generalized Anxiety Disorder (3.7%) were the most common diagnoses. In addition, 11.2% of consecutive primary care attenders had ‘sub-threshold’ psychiatric disorders (i.e., they suffered from symptoms in at least two different areas among those listed in ICD-10, but they did not satisfy diagnostic criteria for well-defined disorders). Psychiatric disorders were more common among females and those aged 24-44 years. Only 20.6% of the subjects with psychiatric disorders contacted the general practitioner for their psychological symptoms, 5.7% complained of symptoms which might have had a psychological origin, whereas in about 70% of the cases the psychiatric disorder was concealed behind the presentation of somatic symptoms, pains in various parts of the body or chronic physical illness. Sixty-two percent of the subjects with psychiatric disorders rated their health status as fair or poor, as compared to 52.0% of those with chronic physical illness and 31.3% of those without such disorders. According to the general practitioner, 40.1% of the subjects with psychiatric disorders and 45.3% of those with chronic physical illness had a fair or poor health status, compared to 14.4% of those without such disorders. Disability in occupational and other daily activities was reported by 52.5% of the subjects with psychiatric disorders (in 40.1% of the cases disability was moderate or severe), 44.4% of those with chronic physical illness (in 26.8% of the cases disability was moderate or severe), and 15.0% of the subjects without such disorders (in 9.1% of the cases disability was moderate or severe). According to the interviewer, disability was identified in 48.4% of the subjects with psychiatric disorders, 39.0% of those with chronic physical illness, and 27.6% of the subjects without such disorders. Sixty per cent of the subjects with psychiatric disorders suffered from concurrent chronic physical illness; these subjects had a poorer health status and higher disability levels than those with psychiatric disorders only. Conclusions - Psychiatric disorders among primary care attenders are frequent and represents a major public health problem, since they entail severe functional limitations for the patients and high costs for the society. Thus, appropriate programs for their recognition and treatment are needed.

Different psychiatric disorders, such as schizophrenia with predominantly positive and negative symptomatology, major depression, generalized anxiety disorder, agoraphobia, obsessive-compulsive disorder, multi-infarct dementia, senile dementia of the Alzheimer type and alcohol dependence, show EEG maps that differ statistically both from each other and from normal controls. Representative drugs of the main psychopharmacological classes, such as sedative and non-sedative neuroleptics and antidepressants, tranquilizers, hypnotics, psychostimulants and cognition-enhancing drugs, induce significant and typical changes to normal human brain function, which in many variables are opposite to the above-mentioned differences between psychiatric patients and normal controls. Thus, by considering these differences between psychotropic drugs and placebo in normal subjects, as well as between mental disorder patients and normal controls, it may be possible to choose the optimum drug for a specific patient according to a keylock principle, since the drug should normalize the deviant brain function. This is supported by 3–dimensional low-resolution brain electromagnetic tomography (LORETA), which identifies regions within the brain that are affected by psychiatric disorders and psychopharmacological substances.

Part 1 of this article, published in Volume 12, Issue 2, probed factors associated with autism. Many of those factors had to do with how toxic substances are polluting our environment. Investigative chicanery involving one neurotoxic agent in particular (thimerosal) was uncovered. The controversy surrounding this neurotoxic agent was examined in some detail, and questions were raised whether information about the degree of toxicity of thimerosal was being minimized, distorted, or covered up by authorities and agencies in positions of influence. Other potentially harmful sources that might differentially contribute to what some might regard as an autism epidemic were listed and described as well.In this section, science and scientific investigation are described, with particular reference to the complexities, intricacies, and difficulties inherent in conducting research on autistic children, and how these intricacies complicate drawing definitive conclusions about if, how, or why a treatment method did or did not work. In addition, seven treatment approaches to autism are listed, along with concise descriptions of these methods and a general rationale underpinning each method. Considerable attention is paid to applied behavior analysis (ABA) because most behavioral treatments derive from it. Commentary on other treatments is provided, such as psychoanalysis, special diets, and chelation. In particular, aftereffects associated with medication tactics are noted.
