as one component of their care. A number of<br />

conditions to the use of the drugs were suggested,<br />

including:<br />

● Diagnosis that the <strong>for</strong>m of dementia is AD must<br />

be made in a specialist clinic according to<br />

st<strong>and</strong>ard diagnostic criteria.<br />

● Assessment in a specialist clinic, including tests<br />

of cognitive, global <strong>and</strong> behavioural functioning<br />

<strong>and</strong> of activities of daily living, should be made<br />

be<strong>for</strong>e the drug is prescribed.<br />

● Clinicians should also exercise judgement about<br />

the likelihood of compliance; in general, a carer<br />

or care-worker who is in sufficient contact with<br />

the patient to ensure compliance should be a<br />

minimum requirement.<br />

● Only specialists (including old-age psychiatrists,<br />

neurologists <strong>and</strong> care of the elderly physicians)<br />

should initiate treatment. Carers’ views of the<br />

patient’s condition at baseline <strong>and</strong> follow-up<br />

should be sought. If GPs are to control<br />

prescribing, it is recommended that they should<br />

do so under an agreed shared-care protocol<br />

with clear treatment endpoints.<br />

● A further assessment should be made, usually<br />

2–4 months after reaching maintenance dose of<br />

the drug. Following this assessment, the drug<br />

should be continued only where there has been<br />

an improvement or no deterioration in MMSE<br />

score, together with evidence of global<br />

improvement on the basis of behavioural <strong>and</strong>/or<br />

functional assessment.<br />

● Patients who continue on the drug should be<br />

reviewed by MMSE score <strong>and</strong> global, functional<br />

<strong>and</strong> behavioural assessment every 6 months.<br />

The drug should normally only be continued<br />

while their MMSE score remains above<br />

12 points <strong>and</strong> their global, functional <strong>and</strong><br />

behavioural condition remains at a level where<br />

the drug is considered to be having a<br />

worthwhile effect. When the MMSE score falls<br />

below 12 points, patients should not normally<br />

be prescribed any of these three drugs. Any<br />

review involving MMSE assessment should be<br />

undertaken by an appropriate specialist team,<br />

unless there are locally agreed protocols <strong>for</strong><br />

shared care.<br />

These recommendations have resulted in a change<br />

in the provision of dementia services. Increased<br />

dem<strong>and</strong> has generally been met by stretching<br />

existing resources within generic old-age<br />

psychiatric services, leading to a relatively low<br />

penetration into the pool of unmet need <strong>for</strong> care<br />

in dementia. One response has been to establish<br />

memory clinics; however, these vary from large<br />

centres of research excellence to more traditional<br />

outpatient-style clinics. Memory clinics have the<br />

capacity to see only a small proportion of people<br />

with dementia <strong>and</strong> are currently not universally<br />

available. 31 The role of specialist services <strong>and</strong><br />

memory clinics has been further clarified by the<br />

National Service Framework <strong>for</strong> Older People. 32<br />

This states that patients should be referred to<br />

specialist services <strong>for</strong> diagnostic uncertainty, <strong>for</strong><br />

consideration of drug therapy or if the patient is a<br />

danger to themselves or others, such as in<br />

consideration of fitness to drive.<br />

Current best practice is <strong>for</strong> care of the person with<br />

AD to be provided by a multidisciplinary team.<br />

This may consist of a consultant old-age<br />

psychiatrist, community mental health nurses,<br />

clinical psychologists, occupational therapists <strong>and</strong><br />

social workers. Additional support may be<br />

provided by other professionals allied to medicine<br />

<strong>and</strong> community services such as domiciliary care,<br />

outpatients services, outreach services <strong>and</strong><br />

daycare. 32 The aim of treatment is to support<br />

patients in the community <strong>and</strong> in their own homes<br />

if possible. In addition, dementia patients may<br />

have access to day hospitals <strong>and</strong> acute <strong>and</strong><br />

rehabilitation hospital beds. Other aspects of care<br />

consist of financial <strong>and</strong> legal support <strong>and</strong> help <strong>for</strong><br />

carers (Mather R, Ox<strong>for</strong>d Memory Clinic, Personal<br />

communication; 2004; Buss L, Southampton<br />

Memory Clinic, Personal communication; 2004 33 ).<br />

Patients with more severe dementia may benefit<br />

from <strong>memantine</strong>, which is licensed <strong>for</strong> the<br />

treatment of moderate to severe AD, although<br />

there is currently no guidance on its use.<br />

Day-to-day care <strong>for</strong> those with dementia is<br />

frequently undertaken by family carers. Caring<br />

<strong>for</strong> someone with dementia can be very<br />

burdensome; people with dementia may have<br />

communication difficulties, challenging behaviour,<br />

incontinence, problems with eating <strong>and</strong><br />

difficulties with other activities of daily living 34<br />

<strong>and</strong> carers require extra support. In many cases<br />

these family carers are frail themselves. In some<br />

cases support can be provided by the local<br />

authority, <strong>for</strong> example by equipment <strong>and</strong> house<br />

adaptations, ‘home help’, ‘meals-on-wheels’ <strong>and</strong><br />

occasionally respite care schemes; however, these<br />

are often limited resources <strong>for</strong> carers <strong>and</strong> the level<br />

of assistance can differ between local authorities. 35<br />

Residential <strong>and</strong> nursing homes provide an<br />

essential contribution towards the care of people<br />

with dementia, with most people with dementia<br />

cared <strong>for</strong> within the private sector 36 with social<br />

services contributing to the cost of care on a<br />

means-tested basis.<br />
