Hence free-foating anxiety includes experiential features of the alarm reaction but marked out as abnormal by the intensity blood pressure iphone 4 mg aceon fast delivery, the prolonged duration blood pressure 9070 order aceon 4 mg otc, the trivial nature of the triggering events and fnally by the socially disruptive and disabling nature of the experience fetal arrhythmia 37 weeks cheap aceon 8 mg overnight delivery. Anxiety can be focused on a specifed object or situation and this is termed phobia arrhythmia with pacemaker order aceon 4 mg with visa, it can occur as paroxysmal and episodic attacks as in panic, or it can be discomforting if unregulated as in obsessive-compulsive phenomena. Montanus speaks of one that durst not walk alone from home for fear that he should swoon or die. A third dares not venture to walk alone, for fear he should meet the devil, a thief, be sick; fears all old women as witches; and every black dog or cat he sees he suspecteth to be a devil; every person comes near him is malifciated; every creature, all intend to hurt him, seek his ruine; another dares not go over a bridge, come near a pool, rock, steep hill, lye in a chamber where cross beams are for fear he be tempted to hang, drown or precipitate himself. If he be in a silent auditory, as at a sermon, he is afraid he shall speak aloud, at unawares, something undecent, unft to be said. If he be locked in a close room, he is afraid of being stifed for want of air, and still carries bisket, aquavitae, or some strong waters about him for fear of deliquiums, or being sick; or if he be in a throng, middle of a church, multitude, where he may not well get out, though he sit at ease he is certase affected. He will freely promise, undertake any business beforehand; but when it comes to be performed he dares not adventure, but fears an infnite number of dangers, disasters, etc. There are at least three conceptualizations of stress: stress as a stimulus; stress as a response; and stress as an interaction. The notion of stress as a stimulus is modelled on the assumption that it is an external factor that affects an individual, whereas stress as a response locates the stress within the individual. This latter notion was developed by Selye (1907–1982), who defned stress as a ‘nonspecifc response of the body to any demand made upon it’ (Selye, 1956). The alarm reaction, typically termed the fight-or-fght response, involves autonomic arousal mediated by release of catecholamines and is experienced as fear, palpitations or readiness for action, amongst other things. In the event that the stressor persists, there is decreased release of catecholamines and a switch to release of glucocorticoid hormones during the resistance phase. And, fnally in contexts of chronic stress, exhaustion is the result with the potential for hypoglycaemia and death. An understanding of Selye’s General Adaptation Syndrome, particularly the physiological and experiential aspects of the alarm reaction (fight-or-fght response) sets anxiety and anxietyrelated emotional disturbance in context. The fve abnormal phenomena of this chapter are relatively common human experiences and can be construed as emanating from disturbances of the regulation of anxiety. Abnormality in this context is marked out by the severity and intensity of the experience, prolonged duration, occurrence in reaction to what could be considered an inadequate situational stress and the deleterious and disabling effect on social functioning. Each of these phenomena has a normal, even necessary, aspect: it is appropriate to be anxious at the beginning of a speech in public; it is normal for a parent to express irritability when an 8-year-old son breaks a window – it is a necessary learning experience for him; fear is necessary for coping when an individual suddenly discovers him or herself to be surrounded by poisonous snakes; meticulous checking and checking again is an important part of learning to be a competent airline pilot; even panic is normal, in a statistical sense, in some situations of extreme mass disaster. In any modern consideration of anxiety disorders, anxiety, panic and phobia would be included both as states of emotion and as distinct syndromes (Noyes and Hoehn-Saric, 1998). Irritability is a distinct and important mood state that occurs in several different conditions, and obsession is both an individual symptom and an essential feature of obsessive-compulsive disorder. Superfcially, obsession and compulsion can seem unrelated to anxiety but both can be construed as means of regulating anxiety. Patients may have insight and present themselves as suffering from ‘phobia’, ‘obsession’ or ‘anxiety state’. However, the lay meaning of each of these terms is signifcantly different from their psychiatric use, and it will be more usual for the clinician to diagnose the state from a description of the mood or thought process. It is clear that levels of arousal relate to the effciency of an organism’s ability to respond appropriately to a task: too little arousal and excessive arousal are both associated with poor performance (this is the Yerkes-Dodson Law) (Yerkes and Dodson, 1908). Lader and Marks (1971) have discussed the features of anxiety in terms of the emotion being normal or pathological. In rather concrete terms, a man who discovers that he is sharing a feld with a bull feels acutely anxious and runs at top speed for the gate; if, six weeks later, when back in the city, he has a panic attack and has to lie down because someone mentions a part of the city called the Bullring, his response is clearly maladaptive and his anxiety pathological. Anxiety may also, arbitrarily, be polarized between state and trait (Sims and Snaith, 1988). Anxiety state is the quality of being anxious now, at this particular time, probably as a reaction to provoking circumstances. Anxiety as a description of the experience of normal emotion is not different in quality, only quantitatively, from anxiety state (Hamilton, 1959). The word angst is etymologically associated with the idea of narrowness, stricture, ‘straits’, and in early usage was located in the praecordium and prominently associated with angina (Sims, 1985). The patient with anxiety state may feel restless, uncertain, vulnerable, trapped, breathless, choked. As well as feeling frightened and worried, hypochondriacal ideas and even feelings of guilt are often prominent. Symptoms of anxiety occur pathologically in anxiety states without obvious external cause. The anxiety is not attached to any specifc provoking object, and so it is termed free­foating anxiety. There is also a contrast between the experience of anxiety as a subjective emotion and the objective occurrence of physiological somatic changes normally associated with that affect; some of the commoner symptoms are shown in Box 17. Tyrer considers irritability to be a symptom of anxiety state, but Snaith and Taylor (1985) made the case for irritability being an independent mood state that may be associated with anxiety – or any other mood disorder. Although it is usual to fnd the psychological and physical aspects of anxiety associated and related in intensity, this may not necessarily be so. The patient may complain of feeling extremely anxious but show minimal somatic expression; in dissociation, marked physical changes have been described when the patient does not complain at all of feeling anxious. Psychiatric nosology makes a distinction between three principal anxiety syndromes: generalized anxiety disorder, social and specifc phobias and panic disorder. The worry is typically focused on everyday matters, and over time it shifts from item to item; the subject is almost never free from anxiety. Patients with anxiety disorder describe characteristic ideational components, concentrating on themes of personal danger and especially physical harm (Hibbert, 1984). The ‘most important’ thought of patients included ‘I may panic in front of others’, ‘I may die of a heart attack while asleep’ and ‘I am going to have a heart attack’. Fear of physical, psychological or social disaster also occurred during panic attacks. Stressful life experiences in the preceding 12 months, and some physiological disturbance other than anxiety immediately before the symptoms, were commonly described. Worry is now recognized as a cognitive process common during the experience of anxiety. It has been defned as: A chain of thoughts and images, negatively affect­laden and relatively uncontrollable. The worry process represents an attempt to engage in mental problem­solving on an issue whose outcome is uncertain but contains the possibility of one or more negative outcomes. The capacity for refection is decreased and the feld of conscious awareness narrowed; this obviously has survival value for instant physical action but is a disadvantage when planning, reviewing and taking a variety of different factors into consideration are important. The variations of activity with anxiety are seen, for instance, after the experience of disaster: some victims will be numb and inert; others tense, restless and constructively overactive; and others still terrifed, almost literally ‘petrifed’, and incapable of sustained activity. Under general anxiety are included free-foating autonomic anxiety; panic attacks; and the observation during interview that the patient appears to be anxious, tense, worried or apprehensive. Free-foating anxiety comprises such autonomic components as blushing, ‘butterfies in the stomach’, choking, diffculty in getting the breath, dizziness, dry mouth, giddiness, palpitations, sweating and trembling, dilated pupils, raised blood pressure; parasympathetic aspects include nausea, vomiting, frequency of micturition and diarrhoea. The psychological quality of feeling anxious or tense is more diffcult to quantify than its physio logical correlates. Words are idiosyncratic in their meaning, and so there is a tendency to judge the veracity of the patient’s statement that he is ‘terribly anxious’ according to the severity of the autonomic symptoms occurring concurrently. However, it is possible by using serial rating scales to compare the patient’s subjective experience at different times; one much-used example of this is the Hospital Anxiety and Depression Scale (Zigmond and Snaith, 1983). Serial recordings of a patient who showed both anxiety and depressive symptoms that responded to treatment at different times are shown in Figure 17. Self-description of anxiety includes worry, brooding, sleeplessness through preoccupation with contents of the thoughts and so on. The attack ends either with a complete interruption to the patient’s current stream of behaviour so that he lies on the foor, rushes into the open air, runs back into the house or ‘collapses’, or he terminates his current behaviour voluntarily so that the attack remits more gradually. In either case, there is something about his mode of activities before the attack that was precipitating panic. The patient makes this association for himself, and he goes to elaborate lengths to avoid provoking a panic attack.

discount 4 mg aceon

In the past decade there has been increasing interest in impulsivity as a concept as well as in defning a number of impulse control disorders prehypertension blood pressure diet buy 8mg aceon fast delivery. Impulsivity is seen as a predisposition towards rapid arrhythmia in fetus buy discount aceon 2 mg on line, unplanned reactions to blood pressure chart according to age buy cheap aceon 4 mg internal or external stimuli and without due regard to heart attack radio edit trusted 4mg aceon the negative consequences of these actions for the impulsive individual or for others (Moeller et al. The essential elements are predisposition, rapid unplanned action and lack of regard for consequences. This suggests that the term is now being used to identify a trait rather than isolated behaviour that is associated with an episode of illness. The current psychological literature, in turn, focuses on behaviourist concepts that are derived from experimental animal models. Once again, these conceptualizations of impulsivity suggest that impulsivity is a trait. On the other hand, the older psychiatric literature focused on impulsive behaviour as part of episodes of illness: ‘of all the morbid desires, the violent impulse [my emphasis] to muscular activity, to bodily movement, is particularly to be noticed, as it is seen, especially in states of mania, as a constant necessity to restless motion hither and thither, beating about, screaming, etc. Bleuler (1911) distinguishes between impulsive acts and compulsive acts: ‘The action appears to him as something beyond his voluntary control. Disorders of impulse control include impairment of control resulting in disinhibition and can be manifest in acquired brain injury, schizophrenia, mania, episodic dyscontrol syndrome and antisocial and emotionally unstable personality disorders. Excessive control of impulses can result in inhibited behaviour and lack of spontaneity, present in anxiety-related disorders including avoidant personality disorder. Aggression is defned as ‘a verbal or physical attack on other living creatures or things’ (Scharfetter, 1980), and aggressiveness as a readiness to be aggressive. In general ethological terms, this is required by animals for survival and by humans to cope with individual conficts and problems in their society. The two concepts of aggression that Scharfetter contrasts are an innate drive and an acquired response. The former theory is followed both by ethologists such as Lorenz (1963) and in classical psychoanalysis in the writings of Freud and of Adler (1929); if aggression is an innate drive, it must fnd some form of expression. Learning theory would suppose that aggression is an acquired reaction in response to external stimuli, especially the expression of others’ aggressive behaviour, and it is reinforced by the success it achieves. On the way home I was seized by an idea out of the blue – swim across the river in your clothes. It was not so much a compulsion to be reckoned with but simply one, colossal, powerful impulse. I did not think for a minute but jumped straight in only when I felt the water did I realize it was most extraordinary conduct and I climbed out again. For the frst time something inexplicable, something quite sporadic and alien, had happened to me. She sat motionless for prolonged periods, disinterested in her surroundings, although she appeared alert She ate and moved slowly but was not stiff. On the second day, suddenly and without warning, she leapt from the chair and grabbed the throat of a passing therapist, severely damaging the therapist’s thyroid. Destruction of property occurred, including holes punched in walls and furniture broken plus poorly coordinated assaults on family members and some neighbours. Gambling, misuse of substances, sexual acts associated with disinhibition and stealing are but some of the behaviours that can occur impulsively. Such insane impulses undoubtedly do occur, and I have been consulted by patients who have told me that loss of control of this kind would come upon them like a storm, and that they would seek shelter anywhere to avoid the danger which might arise to themselves or others. I should hesitate before accepting impulses, unless I had evidences of insanity in other members of the family, or neuroses such as neuralgia or epilepsy in the patient himself. In practice, such public behaviour is quite commonly associated with mental illness. In a study of mentally disturbed people coming to the attention of the police, there was a tendency for such people to create their disturbance near the city centre rather than at the periphery. Of the situations resulting in the involvement of the police, assault and damage were frequent, but it was the bizarreness of the behaviour that marked the person as being mentally ill; for example a man who proffered a windscreen wiper as fare for travelling on a bus, or a woman who presented herself mute at a hostel. On subsequent admission to hospital, diagnosis was predominantly of psychotic illness (57 per cent), with schizophrenia accounting for 40 per cent (Sims and Symonds, 1975). Excessive aggression, and especially unprovoked inappropriate or misdirected aggression, is much more often presented for psychiatric evaluation than a pathological lack of aggressive behaviour. Excessive aggression may be considered both in relation to the underlying psychiatric illness and according to the specifc nature of the behaviour. It is frequently associated with apathy in acute organic disorders such as encephalitis, or in progressive dementia, although irritability and fractiousness may also occur. Generalized debilitating physical illness is normally accompanied by listlessness and apathy. In schizophrenia, aggression is usually markedly reduced, with lack of volition and failure to initiate any directed activity; however, unprovoked violence may also occasionally occur. In depressive psychosis also, reduced aggression is much the most common presentation; however, homicide, quite often associated with suicide, is certainly described among severely depressed individuals with depressive delusions. A consistently low level of aggressiveness may occur as a personality characteristic, for example with dependent disorder of personality. It may be seen as part of a neurotic reaction or during adverse life situations, for instance with the grief of bereavement or the unhappiness of feeling lonely. A certain degree of aggression is necessary for many of the social activities of normal life, and its absence impairs functioning. Disturbance of Movement and Behaviour Behavioural and movement disturbances may have crucial diagnostic signifcance, especially when there is diffculty with verbal explanation. The distinction between movement and behaviour is arbitrary, as will be shown, especially when schizophrenia is considered. Some of these disorders of movement are involuntary and are appropriately regarded as neurological, some are voluntary but carried out unconsciously and some are deliberate actions (of the will). The words used mostly describe the objective characteristics of the action to an outside observer, not the subjective experience of the actor. These disorders of movement are now considered briefy, starting with abnormalities of increased movement – agitation and hyperactivity, and decreased movement – retardation. There are psychiatric sequelae of primary movement disorders including parkinsonism, and often there is disorder of movement associated with conditions that are primarily psychiatric. Agitation Agitation implies mental disturbance causing physical restlessness and increased arousal; it is phenomenologically a description of a subjective mood state associated with and resulting in physical expression. The patient may describe his affect as ‘feeling agitated’, and both he and the external observer see motor restlessness as being logically connected with this. It is demonstrated in many different mental states; pathologically, it may occur with affective psychoses, with schizophrenia, with organic psychosyndromes such as senile dementia or with neurotic and personality disorders, especially states of anxiety. Agitation is quite often a symptom of physical illness, for example hyperthyroidism or hypoparathyroidism. Although retardation is more commonly seen with ‘endogenous depression’ or melancholia, agitation may occur, either without retardation in alternating phase with retardation, or concurrently with retardation in a mixed affective state. Agitated depression is an old term for one variant of a severe depressive episode with or without psychotic component. The practical clinical importance of this mood state ensues from the fact that, whereas suicidal impulses may be prevented from expression by retardation, agitation with restlessness may render such behaviour more likely. An early response to treatment following electroconvulsive treatment or effective antidepressant medication may result in the patient becoming less retarded and therefore at greater risk of suicide. Hyperactivity this describes the state in which there is increased motor activity, possibly with aggressiveness, over-talkativeness or uncoordinated physical activity. The term is descriptive of behaviour rather than of a subjective psychological state. Restlessness is poorly defned in the psychiatric literature and has diverse and multitudinous causes (Sachdev and Kruk, 1996). Restless hyperactivity or hyperkinesis may occur with a variety of different physical assaults on the brain but is especially prominent as a sequel to head injury in children, in whom it may be associated with impulsive disobedience and explosive outbursts of anger and irritability (Black et al. Over recent years, the condition of attention defcit/hyperactivity disorder, previously described as occurring only in children, has been diagnosed in adults; the childhood disorder does sometimes persist into adult life, but the prevalence of the disorder in adulthood is low compared with that in childhood (Sachdev, 1999). These psychological characteristics result in disturbed behaviour in all areas of life. In adult life, there are persistent diffculties in relationships, usually a poor work record and sometimes also a criminal record. The individual is particularly distractible and prone to be disruptive in a group setting. Considerable comorbidity in children occurs with conduct disorder, oppositional defcit disorder, mood and anxiety disorders and mental retardation (Biederman et al.

Therefore, no method by itself will answer observed many years ago that depressed patients every question definitively. But together, a varioften exhibit personality features that could be ety of methods can significantly extend our abilcategorized into one of two types: sociotropic ity to understand and predict. We begin with an (excessively socially dependent) and autonomous overview of the many forms of observation used (excessively achievement oriented). We then summarize epiBeck proposed that extreme sociotropy or demiological and correlational approaches, lonextreme autonomy traits predispose a person to gitudinal versus cross-sectional approaches, the depression. However, subsequent research did classic experimental method, single-case designs, not support this proposition. The revised thenaturalistic approaches all involve making obserory, labeled the congruency hypothesis, provations of what someone is doing or has done. Casual observation experience of thematically related negative life does little by itself to establish a strong base of events that leads to depression (Beck, 1983). However, it is through such observaSpecifically, this theory predicts that a highly tion that we develop hypotheses that can evensociotropic person who experiences relationship tually be tested. For example, suppose a clinician failures (negative events quite salient to a highly notes on several different occasions that when a dependent person) will become depressed, patient struggles or has difficulty with a specific whereas this is not necessarily true for a highly item on an achievement test, the effect seems to autonomous person (for whom these particular carry over to the next item and adversely affect kinds of negative events are less relevant). To test this prediction, the cliniinform our theories in a type of feedback-loop cian might administer an experimental version system. Of course, the ultimate reason for of the achievement test in which difficult items research is the enhancement of our ability to are followed by easy items. It would then be relpredict and understand the behavior, feelings, atively easy to develop a study that would test and thoughts of the people served by clinical this hypothesis in a representative sample of psychologists. Although carried out in real-life settings, naturalistic observation is more systematic and rigorous than unsystematic observation. It is neither casual nor freewheeling Methods but is carefully planned in advance. While the research also possible that in the midst of observing or may be carried out in the field or in relatively recording responses, the observer may unwitnatural settings, the investigator exerts some tingly interfere with or influence the events degree of control over the events. For example, it is one thing to have patients observation method might be an investigation tell clinicians about their fears or check off items of patient behavior in a psychiatric hospital. Controlled observation can also be used to But with only 10 patients from this particular assess communication patterns between couples hospital, can wide generalizations be madefi As with unsystute for naturalistic observation of conflict and tematic observation, this method can serve as a problem solving in the home, researchers have rich source of hypotheses that can be subjected found this controlled observation method to be to careful scrutiny later. Such observations avoid the artificiality and contrived nature of many Case Studies. Such material might his own powers of observation to construct one also include biographical and autobiographical of the most influential and sweeping theories in data, letters, diaries, life-course information, the history of clinical psychology. Case studies, then, to recall that Freud had available no objective involve the intensive study and description of tests, no computer printouts, and no sophistione person.
