In health care, the word ‘communication’ covers a wide range of interactions, including interpersonal communication, communication technology, medical education, health policy and mass communication. It takes many forms, from a brief informal talk between colleagues to formalised written documents between professionals. The essence of this verbal and written communication is the sharing of information. To make our information exchange more useful and to give it more meaning, the information communicated needs an appropriate framework. For example, the meaning of the diagnosis ‘schizophrenia’ is greatly enhanced by knowledge of the individual patient within the context (the framework) of his or her past history and family background.

Cognitive–behavioural therapy (CBT) is a shortterm, problem-focused psychosocial intervention. Evidence from randomised controlled trials and metaanalyses shows that it is an effective intervention for depression, panic disorder, generalised anxiety and obsessive–compulsive disorder (Department of Health, 2001). Increasing evidence indicates its usefulness in a growing range of other psychiatric disorders such as health anxiety/hypochondriasis, social phobia, schizophrenia and bipolar disorders. CBT is also of proven benefit to patients who attend psychiatric clinics (Paykel et al, 1999). The model is fully compatible with the use of medication, and studies examining depression have tended to confirm that CBT used together with antidepressant medication is more effective than either treatment alone (Blackburn et al, 1981) and that CBT treatment may lead to a reduction in future relapse (Evans et al, 1992). Generic CBT skills provide a readily accessible model for patient assessment and management and can usefully inform general clinical skills in everyday practice.

Reform of mental health legislation has been under consideration for several years in England and Wales (Department of Health, 2000a), where the Mental Health Act 1983 is in force, and in Scotland (Millan Committee Secretariat, 2001), which is governed by the Mental Health (Scotland) Act 1984. The Mental Health (Northern Ireland) Order 1986 is also under review, although the findings have yet to be published.

Most of the excitatory neurotransmission in the central nervous system (CNS) is mediated by the endogenous excitatory amino acids (EAAs) glutamate, aspartate and homocysteine. Most of the endogenous inhibitory neurotransmission is mediated by gamma-aminobutyric acid (GABA). EAAs modulate the firing of almost all neurons in the CNS, as excitatory neurotransmission can result in both neuronal inhibition and excitation. The glutamate system is the best characterised of the EAA systems (Box 1).

The National Health Service (NHS) spent £10 billion (40%) of its total budget on people aged 65 and over in 1998/1999. The profile of the health and social care of older people has been raised recently by the publication of the National Service Framework (NSF) for Older People (Department of Health, 2001). The NSF contains standards that older people can expect when they receive health and social care (Box 1). The document also discusses in detail medication management issues in older people. Its two aims in this area are to ensure that older people gain the maximum benefit from their medication in order to maintain or improve quality and duration of life, and do not suffer unnecessarily from illness caused by excessive, inappropriate or inadequate consumption of medicines.

A classification system can benefit disturbed children enormously by bringing to bear a wealth of knowledge and experience. This can make all the difference between an inadequate consultation and a precise formulation of the nature and extent of a child's difficulties, their cause, the likely outcome and a realistic treatment plan. However, inappropriate application of a diagnostic label that has little validity could do more harm than good, and classification systems can be misused. This paper discusses, with examples, issues particular to childhood and adolescence that diagnostic systems need to address if they are to be useful. It considers different solutions applied by the two most widely used schemes, the International Classification of Diseases (ICD–10; World Heath Organization, 1992) and the Diagnostic and Statistical Manual of Mental Disorders (DSM–IV; American Psychiatric Association, 1994). Finally, the types of criteria used to validate categories are discussed.

Violence towards psychiatrists has been recognised as an occupational hazard for many years. With the development of community care it is increasingly likely to be encountered outside the hospital. To maximise personal safety in the community, psychiatrists need to be working in trusts in which an infrastructure to establish and maintain safety standards is in place.

Almost all current research into developing new pharmacological treatment for depression and schizophrenia is focused directly on modulating neurotransmitter receptors in the brain. This approach was stimulated by the chance discovery of the prototype psychotropic drugs such as chlorpromazine and imipramine and the subsequent development of hypotheses based on the presumed mode of action of these drugs. Even clozapine was first introduced as yet another dopamine receptor blocker, and it was only after it was recognised that clozapine shows improved efficacy that hypotheses were developed as to its possible mode of action. Subsequent research based on the receptor approach has led to improved side-effect profiles for modern psychotropic agents, but has not resulted in any improvement of efficacy over and above that of the drugs discovered by good fortune rather than by hypotheses.

The family and therapy

The term family therapy can be misleading. ‘Family’ is open to many interpretations, if not attacks, because it is frequently read as implying a two-parent, heterosexual couple with two children, with the woman primarily the ‘homemaker’ and the man the ‘breadwinner’, with occasional backup from the grandparents. Such a picture would seem to marginalise or exclude other family forms, such as childless couples, single parents with children, gay or lesbian couples and unattached elderly persons. However, the reality is that family therapists treat many different forms of committed relationships and friendships. As to the term therapy, it tends to imply the presence of illness or dysfunction, located in the family rather than one of its individual members, and may thus be quite unacceptable to families who often believe that it is the patient and not them whom requires help. Being at the receiving end of family therapy can have strong connotations of blame. Practitioners therefore increasingly use the term systemic therapy, which is also more informative because some of the work often involves the wider system. The systemic approach is essentially a contextual approach – seeing and treating people in context.
