Psychological Factors in Ageing
Mental State and Physical Performance
There is a relationship between mental state and physical performance; e.g. when we respond to a situation with a physical reaction, concentrate on a task and try not to let our nerves get the better of us, or simply do a job where we are under a certain amount of stress/pressure.
The ability to relax mentally and physically is of great benefit to those subjected to worries and anxieties during the course of everyday life. Occasionally, these problems need to be dealt with by someone other than the person him/herself. On the whole, exercise increases general well-being, renewing mental energy and drive, which is where the expertise of physiotherapist is most beneficial.
The four major pathological conditions in the older population are:
- Acute confusional state (Delirium). Characteristically occurs over hours or days, usually accompanied by acute physical illness. Levels of alertness fluctuate, being worse at night, with lucid spells during the day, although the person can be disorientated to time and place. They may be fearful, irritable and aggressive. Paranoid ideas are common as are visual and auditory hallucinations. Symptoms generally resolve when the underlying cause is treated.
- Depression, characterised by abnormally lowered mood may develop over weeks or months. The signs include loss of interest in life, neglect of personal appearance and hygiene plus expression of recurrent thoughts of death or suicidal ideas. Concentration levels are low, decisions difficult to make as are the carrying out of daily tasks. The person may complain of multiple physical symptoms, sleep (insomnia or hypersomnia) and appetite also become affected with a resultant decrease in energy.
- Paraphrenia is not universally accepted as a distinct syndrome. The person is often female, lives alone, and has evidence of difficult social interactions earlier in life. They report of plots against them, focusing on family members, which are persistent, extreme, and elaborate. Usually, cognitive impairment is not present, but a hearing impairment is common. Although the person is physically independent (diet and hygiene are rarely compromised), social functioning and cooperation with staff members are greatly impaired.
- Dementia is an umbrella term used for signs and symptoms characterised by a generalised and irredeemable impairment of intellect, memory and personality. The decline is permanent and progressive. The three most common types of dementia are:
- Alzheimer’s disease: a neurodegenerative disorder with generalised brain cell loss, especially in the cortex, plus extracellular plaques and intracellular neurofibrillary tangles. It has a progressive unremitting course with widespread loss of function and abilities. Alzheimer’s disease is slightly more common in women than in men.
- Vascular dementia: small or large vascular lesions cause focal damage in the brain with resultant focal neurological signs. Stepwise deterioration in cognitive and physical function occurs. It is more common in men than in women, and there is usually past history of cardiovascular pathology (e.g. hypertension).
- Lewy Body dementia: presents with a very different patterns of symptoms including clouding of consciousness, paranoid delusions, complex visual hallucinations, falls, depressive symptoms and auditory hallucinations.
As people get older there is an increased likelihood of them experiencing bereavement. Most come through the experience without the need for professional help, but for some there are longer lasting detrimental effects on physical and mental health. This may leave someone in a pattern of grief and mourning, experience some or all of the following:
An initial experience of numbness (sense of isolation, withdrawal, loss of appetite) and denial (constant reminiscing, expects the return).
In the first 3 months it could be anxiety (sense of insecurity, often irrational fears), anger (‘why me’), pain, guilt (self-recrimination)
From 3 months onwards, depression is more likely, exacerbating existing personality problems, apathy (neglects own best interests, lack of will) and possible a loss of identity
For the first year or more we should expect acceptance (can settle into new circumstances, loss no longer felt as an appalling tragedy) and healing when equilibrium is regained. The depression may continue in older people, and if severe is a suicide risk that needs recognition and treatment. Liaison with clinical psychologist, community psychiatric nurse, GP or other mental health professionals is appropriate.
Consider the psychological factor of adjustment to physiological change that has left a disability, e.g. a stroke. It may mean lifestyle changes such as having a bed downstairs, leading to loss of privacy, or having to give up driving, leading to isolation. A major disability may also alter the person's position or status within the family, for example, a change from being a carer to being cared for may lead to low esteem. Healthcare professionals may sometimes overlook the acceptance of these changes as the priority is normally to deal with the physical disability. If the physiotherapist has knowledge of the possible psychological consequences they can refer on to colleagues and ensure a holistic approach to person-centred care is maintained. Occasionally however, the effects of mental health problems can be such that they hinder and limit a person’s participation and progression with physiotherapy, and a different course of management must be sought.
For most of us who are in a general setting, dealing with complex emotions in rehabilitation is vital, as many factors will affect involvement and participation with treatment. The range of patients you will see encompasses people with anxieties born of their pathologies of a non-organic nature; e.g. someone with osteoporosis with a great fear of moving in case they fall and fracture a bone.
How would your response differ to a patient who has anxiety centred on falling, compared to a person with dementia and anxiety about walking outside?
Physiotherapy for mental health problems varies depending on the reason for the condition, and the stage it is at. Some physiotherapists specialise in this clinical area following further post-qualification study. The physiotherapists in mental health are uniquely placed through their knowledge of mental health conditions and their expertise in the management of physical conditions to provide an extensive range of approaches to treatment aimed at relieving symptoms and improving quality of life. They advice and support staff, service users and carers on both the physical manifestations of mental health conditions and on the management of physical conditions in mental health settings.
Many treatments for those with mental health problems are no different from those used to solve physical problems with client groups elsewhere; however, the approach taken may need to reflect the person’s individual health needs. Overall, patience and empathy are a must (with good listening/counselling skills with both client and carers), as are re-orientation to the individual’s environment, and an understanding of their behaviour. Good practice point for people with mental health problems.
The physical treatment may involve:
- A thorough assessment of ability, with involvement from other multidisciplinary team members
- Maintenance of range of movement (especially in the later stages when immobility increases), and work on promoting mobility. Improvement of balance, to minimise the risks of falling, as mobility declines
- Treatment of any specific injuries sustained
- Provision of information to help reduce anxieties and fears and assist in carrying out a specific programme designed for that individual
- Teaching of positioning and manual handling in the later stages of some of the disorders.

In Scotland, the See Me site provides information and fact sheets to download that explain about the national campaign to end the stigma and discrimination of mental ill-health. They are an alliance of five mental health organisations and fully funded by the Scottish Government launched in 2002. http://www.seemescotland.org.uk/
The Social Care Institute for Excellence site (SCIE) is still running a page about ageing, discrimination and mental health in older people. Access this and information sheets at: http://www.scie.org.uk/publications/elearning/mentalhealth/mh08/index.asp
Mind publishes information on many topics relating to mental health. They are grouped into seven broad categories: diagnoses and conditions, treatments, mental health statistics, support and social care, communities and social groups, and society and environment. http://www.mind.org.uk/help/information_and_advice
