Risk for drug interaction increases with the number of drugs ingested, with an interaction rate of 13% with 2 drugs up to a rate of 82% with 7 or more drugs taken. Co-morbid disease will influence prescribing not only due to the impact of the disease in addition to the normal physiological changes of ageing, but also by forcing consideration of drug interactions with the medication already prescribed or sourced for these conditions by the patient. Potentially inappropriate medication prescription may initially present to the psychiatrist acutely as Delirium or as Cognitive impairment. Without a thorough medication and substance use history, prescription of psychotropic drugs can become part of a treatment cascade whereby increasing amounts of inappropriate medication are prescribed to treat the side effects of previously prescribed medication. The elderly are particularly vulnerable to Medication errors at so called ‘transitions of Care’, such as on admission and discharge from hospital or nursing homes. Many older people residing at home need supervision or administration of medication either due to psychiatric illness or cognitive impairment. Those who are disorientated in day and time will not be able to manage even with the assistance of ‘pill-pot’ daily packaging of medication. In summary, the elderly psychiatric patient carries prescribing risks associated with the pharmacokinetics of the ageing body. Heterogeneity of psychotropic pharmacodynamics in this population demands caution both in initiation and monitoring of drug dosages. Inappropriate Prescribing of Medicines - Implications for Older People and Health Budgets. Near or above the age of fifty the elasticity of the mental processes on which treatment depends is as a rule lacking – old people are no longer educable…’ (Freud, 1905). It is rather ironic those comments of Freud, then already at the age of 49, having this view on older people. This therapeutic nihilism has had a profound effect on the development of both psychotherapy theory and services for older people. Psychotherapy theory has tended to focus on childhood development and the developmental stages of infant, child and early-adult life, with later life being neglected as a developmental phase. Currently ‘Late life’ or ‘The Third Age’ is viewed as an important developmental period that can significantly add to a life well lived, if approached as an important period of growth and psychological development. We may experience a time of vitality during which individuals can expect to explore and develop their potentials. Society makes available social services and living options that did not exist a few decades ago. My aim here is to give readers a brief overview of the psychological therapies that may be used when working with older people. Psychological therapies with older people have traditionally held a low position in Old Age Psychiatry and in psychotherapy generally, mainly due to ageism and negative stereotyping about treatability, especially around the impact of cognitive decline on older people With the current high demand on Old Age Psychiatry services for the assessment and treatment of early dementia, depression and anxiety, developments in services are focusing on biological models of illness and pharmacological treatments, again at the expense of psychological therapies. Psychotherapeutic interventions require specific additional skills of the clinician and are not always on hand. Secondly, the psychotherapeutic process may not yield immediate 980 responses and is more time consuming and labour intensive. Beck (1976) argued that the combination of a biological approach with a psychotherapy approach yields better results than either of those therapies alone. While there is no systematic research to suggest that psychotherapies must be adapted for older populations, most experts in psychotherapy with older populations believe that, for older adults to benefit from psychotherapy, the interventions must be modified to accommodate age-related changes in learning, information processing, and health status. In addition, cohort-related beliefs about mental health and psychotherapy should also be considered.

The spiritual aspect of the patient’s health is considered to begin with Step 1 (Pizzorno & Snider Note: The actual therapeutic order may change depending on the 2004). The philosophy represented in the naturopathic therapeutic order does not determine what modalities are ‘good or bad’, useful or useless. Rather, it provides a clinical framework for all modalities, used in the order consistent with that of the natural self-healing process.
