ICD-10/DSM-5 index

This chapter is an index of ICD-10 and DSM-5 category codes and their relation to other information within this book.

Therapeutic issues

This chapter covers therapeutic issues in psychiatry, from medication adherence, off-label prescribing and associated legal considerations, negative side effects such as weight gain and sexual dysfunction in different forms of psychiatric medicines, potential interactions or contraindications for prescribing, and specific side effects. Special prescribing cases, such as psychiatric medicine in pregnancy and breastfeeding patients or those with heart, liver, or kidney disease, are explained.

Psychotherapy

This chapter covers the psychotherapies, a collection of treatments for mental disorders which employ language and communication as a means of producing change. It covers assessment and selection of an appropriate method for the individual patient, a history of Freud and other pioneers of psychotherapy to provide a background context, before examining different types of therapy. Briefly explaining the theory of psychotherapy, the phases of psychosexual development, and the object relations theory, it goes into detail on behavioural therapies such as cognitive behavioural therapy, interpersonal psychotherapy, dialectical behaviour therapy, and solution therapy. Counselling methods are described to aid the reader in developing their skills.

Liaison psychiatry

This chapter concerns liaison psychiatry and the assessment and management of psychiatric and psychological illnesses in the general medical population. It covers the 12 most common referral types, assessment of depressive and anxiety symptoms, psychotic symptoms and confusion, depression in physical illness, delirium, and management after self-harm. Focusing on capacity and consent, as well as differential diagnoses and potential management principles for medically unexplained symptoms, it covers the basis of working as a psychiatrist in a hospital.

Forensic psychiatry

Covering the role of the psychiatrist in forensic situations, from participation in the criminal justice system and legal definitions of crime (including homicide, violence, and sexual offences) to the relationship between mental disorders and offending, this chapter addresses secure hospitals and units, police and court liaison, and the role of the prison psychiatry. Legal provisions and how to give evidence in court are described, and an overview of pathways through the criminal health and justice system for mentally disordered offenders is provided. Fitness to plead and criminal responsibility are both explained.

Eating and impulse-control disorders

This chapter covers eating disorders. For anorexia nervosa, an overview, the physical consequences, methods of assessment, and in- and outpatient management are discussed. Similarly, the definitions and management for bulimia are also described, with a brief overview of binge eating disorder. Impulse-control disorders are subsequently defined, from pyromania, kleptomania, and intermittent explosive disorder to gambling and trichotillomania. Newer addictive disorders, such as gaming disorder, are also covered.

Depressive illness

This chapter covers depression. After a historical perspective, it describes the symptoms, caseness, and clinical presentations to aid in diagnosis. Epidemiology and aetiology of the disease are both covered, and specific investigations for diagnosis are outlined. The course and prognosis are discussed, and management principles are covered. Both inpatient and outpatient treatment are covered. Treatment methods for depression both with and without psychotic features are defined, and treatment-resistant depression management is also discussed. Antidepressants, including schedules for swapping or stopping drugs, are covered, including tricyclic antidepressants (TCAs), monoamine oxidase inhibitors (MAOIs), and selective serotonin reuptake inhibitors (SSRIs), as well as assorted other pharmaceutical interventions. Electroconvulsive therapy (ECT) is covered in detail.

Useful resources

This chapter lists useful resources, both for patients and clinicians.

Substance misuse

This chapter defines substance abuse. Splitting up alcohol and other drugs, although recognizing that alcohol is a drug in its own right, it covers dependence, screening, assessment, planning treatment, management of withdrawal, and plans for maintaining abstinence. Also covering tobacco, illegal drugs, and novel psychotropic substances, substitute prescribing, and legal issues, this chapter has a table of street slang associated with drug misuse to aid the reader.

Transcultural psychiatry

This chapter covers transcultural psychiatry and culture-bound disorders. It covers culturally influenced variants of universal broad categories of mental disorder, to enable meaningful diagnostic formulation and development of appropriate treatment plans. Summarizing the recent developments in global mental health, it puts cultural context to the presentation of psychiatric disorders, and examples of common cultural concepts of distress are defined.
