The Hamilton Depression Rating Scale (HDRS, or HAM-D (D for depression); Hamilton also created an anxiety scale) has been widely used for more than 5 decades (Hamilton, 1960). The HDRS is not used to make a diagnosis, but to rate severity. A diagnosis must be made before the HDRS is applied. Serial ratings over time reflect change (hopefully, improvement). Because it relies on many vegetative symptoms, the HDRS is not applicable when there is a concurrent severe medical disorder. The original HDRS consisted of 21 items, however, shorter versions are available. Even though the HDRS is not used for diagnosis, many researchers have come to equate the 17-item score of 8, and the 6-item score of 4 with remission. To ensure subjects have at least moderate depression, many studies require a 17-item entry score 18. A COPY OF THE HDRS FOLLOWS THE REFERENCES MONTGOMERY ASBERG DEPRESSION RATING SCALE The Montgomery Asberg Depression Rating Scale (MADRS; Montgomery & Asberg 1979) is another important depression scale. It followed almost two decades after the HDRS, but has been widely used over the last quarter of a century. In contrast to the HDRS, the MADRS is less strongly focused on the somatic symptoms of depression, and more strongly on items such as concentration difficulties, tension, lassitude, pessimistic and suicidal thoughts. The initial hope was that being less focused on somatic symptoms, the MADRS would be more sensitive to change than the HDRS. COPIES OF THE HDRS AND MADRS FOLLOW THE REFERENCES Pridmore S.

INTRODUCTION TO PSYCHIATRY The aim is to present a readable account of the mental disorders and their management. The target population is medical students, but members of the general public may find something of interest. The mental disorders are a huge and incompletely understood entity. They remain a major challenge to science, government and humanity. When the less severe forms are included, it is claimed that about 25% of the people in western populations will experience a mental disorder at some time in their lives (The World Health Report, 2001). The terms mental disorder, psychiatric disorder, mental illness all mean much the same. They refer to a group of recognized medical conditions in which the central feature is psychological distress or disability. There is impact on one or more of mood, thinking and behaviour. There is agreement, for example, that schizophrenia, bipolar disorder, and obsessive-compulsive disorder are among the mental disorders, while armed robbery, chicken pox and getting old are not. The Diagnostic and Statistical Manual is a leading diagnostic system (list of disorders). We need to be alert to the danger of classifying all forms of human experience (such as normal disappointment) as mental disorders. Last modified: November, 2017 2 Classification systems Currently, there are two main classification systems. They are composed by large teams of informed professionals using extensive resources. These separate teams also work together, so that their documents are very similar or the same, in most respects. The American Psychiatric Association produces the DSM (mentioned above). The World Health Organisation produces the International Classification of Diseases. However, in many parts of the world (including Australia) it is predominantly used for administrative purposes (for example, as a tool for the counting of the number of cases of particular disorders presenting at clinics, etc. Basis of Classification th Psychiatry is currently where internal medicine was in the 19 century – that is, psychiatry is classifying disorders according to the appearance and statements made by the patient (signs and symptoms), rather than etiology (McHugh, 2005). However, the current systems of classification do have good reliability, which is a good start. The aetiology, anatomy, physiology and pathology underpinning psychiatric disorders is not clear; work is continuing. This is where you come in – I will tell you all I know, but it is your responsibility to extend our knowledge. Neuroimaging, immunology genetics and epigenetics will be among the useful stepping stones. Symptoms and signs These terms are used in all branches of clinical medicine. If you wake up one morning with a severe pain in your big toe, that is a symptom – a symptom is something the patient notices and usually complains about. If your toe is swollen, red and tender to touch, these are signs – that is, observations which are made during an examination. Recognising a particular pattern (thereby identifying the disorder which the patient is suffering) is called making a diagnosis. The most likely disorder in the case of the painful, swollen, red, tender big toe, would be gout. For most medical disorders special tests, such as blood studies and imaging confirm the diagnosis. Unfortunately, at this time, there are no special tests which confirm the presence of particular mental disorders. However, special tests may be used to exclude certain conditions. For example, imaging excludes brain tumours, which may present with signs and symptoms suggestive of major depression or schizophrenia.

Endophenotype is often used as the descriptive term for Several points must be considered in the assessment of these discrete, genetically determined phenotypes that may endophenotypes. First, because these are putative genetic be part of a complex illness. The search for endophenotypes traits, their biology begins at conception, so that by the is not straightforward because no a priori criterion can be time they are measured in adulthood, their expression may used to decide if a particular element of schizophrenia or have been modified by such factors as development, aging, any other psychiatric illness reflects the effect of a single brain injury, and medication and substance abuse and.

These effect sizes were computed by using the means and standard deviations for the normal comparison subjects and the means of the patient groups. The range of values differs from study to study because different investigators used different patient populations taking different types and amounts of medications; also, the experimental paradigms, although similar, often differed in terms of stimulus parameters. Of course, in some of these studies, multiple conditions were used, some of which were needed to establish floor and ceiling effects. In these cases, we generally cite the most robust effect sizes. Chapter 51: Endophenotypes in the Genetics of Schizophrenia 705 so that if schizophrenia is a multifactorial trait, some siblings 'accounting' for, at most, 50% to 70% of the variance of should express specific phenotypes independently of other the disorder; the remaining variability resides in nongenetic phenotypes. These siblings may be better subjects for char- 'second hits,' such as neonatal or in utero neural damage acterizing the phenotype than the patients themselves, to the developing hippocampus (12–15) or other factors. A plethora of studies indicate that in addition to mutant Finally, because the aim of genetics generally is to identify genes, a second level of environmental or other generalized affected individuals who have or do not have a particular or specific stressor probably must act as a second hit in the genetic abnormality, the measurement of the putative phe- central nervous system. An example of the result of this notype must clearly separate most affected and unaffected need for a second hit is illustrated by the fact that clinically individuals, regardless of whether a quantitative or discrete 'unaffected' relatives of patients with schizophrenia have variable is used. The range of effect sizes for several putative endophenotypic markers of abnormalities in some or all of endophenotypes is shown in Table 51. The measurement of endophenotypes is in itself schizophrenia.
