Post-traumatic Stress Disorder (ptsd): From 1 Different Sources


A term introduced to PSYCHIATRY in 1980 after the Vietnam War. It is one of several psychiatric disorders that can develop in people exposed to severe trauma, such as a major physical injury, participation in warfare, assault or rape, or any event in which there is major loss of life or a threat of loss of life. Most people exposed to trauma do not develop psychiatric disorder; however, some develop immediate distress and, occasionally, the reaction can be delayed for many months. Someone with PTSD has regular recurrences of memories or images of the stressful event (‘?ashbacks’), especially when reminded of it. Insomnia, feelings of guilt and isolation, an inability to concentrate and irritability may result. DEPRESSION is very common. Support from friends and family is probably the best management, but those who do not recover quickly can be helped by antidepressants and psychological treatments such as COGNITIVE BEHAVIOUR THERAPY. Over the past few years, PTSD has featured increasingly in compensation litigation.

Conversion Disorder

A psychological disorder, also called hysterical conversion, in which the affected individual presents with striking neurological symptoms – such as weakness, paralysis, sensory disturbances or memory loss – for which no organic cause can be identi?ed. Up to 4 per cent of patients attending neurological outpatient clinics have been estimated as having conversion disorders. The disorder remains controversial, with theories about its cause unsupported by controlled research results. In clinical practice the physician’s experience and intuition are major factors in diagnosis. It has been suggested that the physical symptoms represent guilt about a physical or emotional assault on someone else. Treatment using a COGNITIVE BEHAVIOUR approach may help those with conversion disorders.... conversion disorder

Stress

Any factor or event that threatens a person’s health or adversely affects his or her normal functioning. Injury, disease or worry are common examples; others include internal con?icts, emotive life events – such as the death of a close relative or friend, the birth of a baby, separation or divorce – pressures at work or a hostile environment such as war or famine. Some individuals seem to be more prone than others to develop medical problems related to stress.

Stress prompts the body to raise its output of HORMONES such as ADRENALINE and CORTISOL, causing changes in blood pressure, heart rate and metabolism. These are physiological responses intended to improve a person’s physical and mental performance – the ‘?ght or ?ight’ reaction to fear. Stress may, however, disrupt the ability to cope. Constant or recurrent exposure to stress may produce symptoms such as anxiety, depression, headaches, indigestion, diarrhoea, palpitations and general malaise (see POST-TRAUMATIC STRESS DISORDER (PTSD)). Treatment can be di?cult and prolonged; counselling can help as can ANXIOLYTICS or ANTIDEPRESSANT DRUGS – but a change in job or lifestyle may be necessary in some circumstances.... stress

Dissociative Disorder

A collection of psychological disorders in which a particular mental function becomes cut o? from a person’s mind. Hysterical AMNESIA is one example, when the person forgets his or her personal history but can still absorb and talk about new events. Other examples are FUGUE, depersonalisation (detachment from self and environment), and MULTIPLE PERSONALITY DISORDER.... dissociative disorder

Multiple Personality Disorder

The individual with this psychiatric disorder has two or more di?erent personalities, often contrasting. The dominant personality at the time determines the behaviour and attitude of the individual, who customarily seems not to know about the other personality – or personalities. The switch from one personality to another is abrupt and the mental condition of the di?ering personalities is usually normal. It is possible that child abuse is a factor in the disorder, which is treated by psychotherapy. The classic multiple personality was the ?ctional form of Dr Jekyll and Mr Hyde.... multiple personality disorder

Obsessive Compulsive Disorder

A mental-health problem which will be experienced at some time by up to 3 per cent of adults. The main feature is the occurrence of spontaneous intrusive thoughts that cause intense anxiety. Many of these thoughts prompt urges, or compulsions, to carry out particular actions in order to reduce the anxiety. One of the commonest obsessions is a fear of dirt and contamination that prompts compulsive cleaning or repeated and unnecessary handwashing. (See MENTAL ILLNESS.)... obsessive compulsive disorder

Seasonal Affective Disorder Syndrome

Known colloquially as SADS, this is a disorder in which an affected individual’s mood changes with the seasons. He or she is commonly depressed in winter, picking up again in the spring. The diagnosis is controversial and its prevalence is not known. The mood-change is probably related to light, with MELATONIN playing a key role. (See also MENTAL ILLNESS.)... seasonal affective disorder syndrome

Personality Disorder

Condition in which the individual fails to learn from experience or to adapt to changes. The outcome is impaired social functioning and personal distress. There are three broad overlapping groups. One group is characterised by eccentric behaviour with paranoid or schizoid overtones. The second group shows dramatic and emotional behaviour with self-centredness and antisocial behaviour as typical components of the disorder. In the third group, anxiety and fear are the main characteristics, which are accompanied by dependency and compulsive behaviour. These disorders are not classed as illnesses but psychotherapy and behavioural therapy may help. The individuals affected are notoriously resistant to any help that is o?ered, tending to blame other people, circumstances or bad luck for their persistent diffculties. (See MENTAL ILLNESS; MULTIPLE PERSONALITY DISORDER; MUNCHAUSEN’S SYNDROME.)... personality disorder

Antisocial Personality Disorder

Impulsive, destructive behaviour that often disregards the feelings and rights of others.

There may be a deadening of feelings, or irritability and feelings of guilt, sometimes building up to depression.

Most people recover, in time, with emotional support and counselling.... post-traumatic stress disorder

Attention Deficit Hyperactivity Disorder

(ADHD) A behavioural disorder in which a child has a consistently high level of activity and/or difficulty in attending to tasks. Attention deficit hyperactivity, or hyperkinetic, disorder affects up to 1 in 20 children in the. The disorder, which is more common in boys, should not be confused with the normal boisterous conduct of a healthy child. Children with consistently show abnormal patterns of behaviour over a period of time. An affected child is likely to be restless, unable to sit still for more than a few moments, inattentive, and impulsive.

The causes of are not fully understood, but the disorder often runs in families, which suggests that genetic factors may be involved. is not, as popularly believed, a result of poor parenting or abuse.

Symptoms develop in early childhood, usually between the ages of 3 and 7, and may include inability to finish tasks; short attention span; inability to concentrate in class; difficulty in following instructions; a tendency to talk excessively, frequently interrupting other people; difficulty in waiting or taking turns; inability to play quietly alone; and physical impulsiveness. Children with may have difficulty in forming friendships. Self-esteem is often low because an affected child is frequently scolded and criticized.

Treatment includes behaviour modification techniques, both at home and at school. In some children, avoidance of certain foods or food additives seems to reduce symptoms. In severe cases, stimulant drugs, usually methylphenidate, may be prescribed. Paradoxically, the use of stimulants in reduces hyperactivity and improves concentration. In general, the condition improves by adolescence but may be followed by antisocial behaviour and drug abuse or substance abuse.... attention deficit hyperactivity disorder

The fracture may be immobilized in a cast.... stress fracture

Attention Deficit Disorder (hyperactivity Syndrome)

A lifelong disorder characterised by overactive behaviour, short attention span and poor concentration. It is thought to be caused by a minor abnormality that affects the part of the brain that allows us to concentrate and focus on tasks. Some scientists have suggested that it may be caused by particular foods, particularly processed foods containing arti?cial additives, and recommend special diets. In some countries, attention de?cit disorder is diagnosed in up to a tenth of all children; this may re?ect di?erences in paediatric practice and diagnosis rather than a real variation in prevalence of the disorder. Behaviour therapy is the main treatment. Those children with very severe symptoms of restlessness, short attention span and disturbed behaviour may respond to additional treatment with methylphenidate (Ritalin®). This is an amphetamine-like drug that is thought to stimulate the part of the brain that is not working properly. Use of this drug has, however, been controversial.... attention deficit disorder (hyperactivity syndrome)

Chronic Disorder

A persistent or recurring condition or group of symptoms. Chronic disorders are customarily contrasted with acute diseases which start suddenly and last a short time. The symptoms of acute disease often include breathlessness, fever, severe pain and malaise, with the patient’s condition changing from day to day or even hour to hour. Those suffering from chronic conditions – for example, severe arthritis, protracted lung disease, ASTHMA or SILICOSIS – should be distinguished from those with a ‘static disability’ following a stroke or injury. Chronic disorders steadily deteriorate, often despite treatment and the patient is increasingly unable to carry out his or her daily activities.... chronic disorder

Post-coital Contraception

Action taken to prevent CONCEPTION after sexual intercourse. The type of contraception may be hormonal, or it may be an intrauterine device (see below, and under CONTRACEPTION). Pregnancy after intercourse without contraception – or where contraception has failed as a result, for example, of a leaking condom – may be avoided with a course of ‘morning-after’ contraceptive pills. Such preparations usually contain an oestrogen (see OESTROGENS) and a PROGESTOGEN. Two doses should be taken within 72 hours of ‘unprotected’ intercourse. An alternative for the woman is to take a high dose of oestrogen on its own. The aim is to postpone OVULATION and to affect the lining of the UTERUS so that the egg is unable to implant itself.

Intrauterine contraceptive device (IUCD) This, in e?ect, is a form of post-coital contraception. The IUCD is a plastic shape up to 3 cm long around which copper wire is wound, carrying plastic thread from its tail. Colloquially known as a coil, it acts by inhibiting implantation and may also impair migration of sperm. Devices need changing every 3–5 years. Coils have generally replaced the larger, non-copper-bearing ‘inert’ types of IUCD, which caused more complications but did not need changing (so are sometimes still found in situ). They tend to be chosen as a method of contraception (6 per cent) by older, parous women in stable relationships, with a generally low problem rate.

Nevertheless, certain problems do occur with IUCDs, the following being the most common:

They tend to be expelled by the uterus in women who have never conceived, or by a uterus distorted by, say, ?broids.

ECTOPIC PREGNANCY is more likely.

They are associated with pelvic infection and INFERTILITY, following SEXUALLY TRANSMITTED DISEASES (STDS) – or possibly introduced during insertion.

They often produce heavy, painful periods (see MENSTRUATION), and women at high risk of these problems (e.g. women who are HIV positive [see AIDS/HIV], or with WILSON’S DISEASE or cardiac lesions) should generally be excluded – unless the IUCD is inserted under antibiotic cover.... post-coital contraception

Post-mortem Examination

Also called an autopsy (and less commonly, necropsy), this is an examination of a body to discover the causes of death. Such an examination is sometimes required by law. An unnatural death; a death occurring in suspicious circumstances; or a death when a doctor feels unable to complete a certi?cate about the cause – all must be reported to the CORONER (in Scotland, to the procurator ?scal). He or she may order an autopsy to be carried out as part of the inquiry into cause of death. Sometimes doctors may request the permission of relatives to perform a post-mortem so that they may discover something of value for the improvement of medical care. Relatives may refuse consent. (See also DEATH, CAUSES OF.)... post-mortem examination

Cardiac Stress Test

One of a group of tests used to assess the function of the heart in people who experience chest pain, breathlessness, or palpitations during exercise. The test establishes whether the patient has coronary artery disease. An ECG machine records the patterns of the heart’s electrical activity while the heart is stressed. This is usually achieved by the patient exercising on a treadmill or cycling. Specific changes in the electrical pattern as exercise levels increase indicate angina. Cardiac stress testing may be used in conjunction with radionuclide scanning to identify damaged areas of heart muscle.... cardiac stress test

Stress Fractures

Stress fractures are comparatively common in sportspeople. They tend to occur when an undue amount of exercise is taken – that is, an amount of exercise which an individual is not capable of coping with in his or her state of training. The main initial feature is pain over the affected bone that has been subjected to abnormal physical stress. This is usually insidious in onset, and worse at night and during and after exercise. It is accompanied by tenderness, and a lump may be felt over the affected site. X-ray evidence only appears after several weeks. Treatment consists of rest, some form of external support, and in the initial stage ANALGESICS to deaden or kill the pain. (See also BONE, DISORDERS OF – Bone fractures.)... stress fractures

insidious numbness in muscles that develops 15–20 years after an attack of *poliomyelitis; the muscles may or may not have been previously affected. It may be caused by loss of nerve cells that have been under greater strain than normal as a result of the polio; there is no evidence of reactivation of the poliovirus. The syndrome also includes other symptoms, such as fatigue and pain, which may be due to secondary mechanical causes.... post-polio syndrome

Insulin Stress Test

an important but potentially dangerous test of anterior pituitary function involving the deliberate induction of a hypoglycaemic episode with injected insulin and the subsequent measurement of plasma cortisol and growth hormone at regular intervals over the next three hours. The stress of the hypoglycaemia should induce a rise in the levels of these hormones unless the anterior pituitary or the adrenal glands are diseased. The test can induce epileptic seizures or angina in those with a predisposition and should not be performed in susceptible individuals. It is often combined with the thyrotrophin-releasing hormone (TRH) test and the gonadotrophin-releasing hormone (GnRH) test in what is known as the triple test (or dynamic pituitary function test).... insulin stress test
