3.2 REVIEWS OF NON-PHARMACOLOGICAL INTERVENTIONS<br />
3.2.1 Introduction<br />
A systematic review of a very broad range of psychological approaches to <strong>the</strong><br />
management of neuropsychiatric symptoms of dementia was published by <strong>the</strong> Old Age<br />
Task Force of <strong>the</strong> World Federation of Biological Psychiatry. 5 The SBU health<br />
technology assessment <strong>report</strong> covering various aspects of dementia, also includes a<br />
systematic review of care interventions. 21 Many studies reviewed in this HTA were<br />
rejected because of lack of adequate diagnoses. 21 The reason suggested could be <strong>the</strong><br />
lack of involvement of a physician in many studies. O<strong>the</strong>r important large reviews are<br />
<strong>the</strong> NICE 1 and <strong>the</strong> DIMDI <strong>report</strong> 28 , and several Cochrane reviews.<br />
These main reviews, as well as o<strong>the</strong>rs will be discussed below, and <strong>the</strong> level of evidence<br />
supporting <strong>the</strong> various interventions will be mentioned.<br />
Interventions may target <strong>the</strong> patient, <strong>the</strong> caregiver or both. Likewise outcomes of <strong>the</strong>se<br />
interventions may be assessed in patients, caregivers or both. Outcome parameters vary<br />
a lot between studies.<br />
Whereas some reviews focus specifically on <strong>the</strong> type of interventions, o<strong>the</strong>r reviews<br />
focus on a specific symptom or cluster of symptoms (mostly behavioral problems e.g.<br />
agitation, aggression, wandering) and consider <strong>the</strong> different interventions to improve it.<br />
Fur<strong>the</strong>r, different authors tend to group <strong>the</strong> studies in different ways, illustrating <strong>the</strong><br />
lack of standardization of interventions in this research area and also illustrating <strong>the</strong><br />
many variations and combinations of interventions that are evaluated in <strong>the</strong> studies. The<br />
fact that few studies addressed <strong>the</strong> same issues in comparable ways is a major<br />
methodological problem, limiting <strong>the</strong> level of evidence which can be associated with<br />
such unique interventions.<br />
In <strong>the</strong> next paragraphs, we will describe:<br />
• Interventions addressing <strong>the</strong> patient<br />
o studies focusing on specific interventions : interventions addressing patient<br />
cognition, patient emotion, patient sensory enhancement; physical activity<br />
interventions; communication/interaction/relationship interventions;<br />
environmental adaptations<br />
o studies focusing on signs and symptoms: non-pharmacological<br />
interventions for challenging behavior, neuropsychiatric symptoms and<br />
wandering<br />
o studies focusing on technological support<br />
• Interventions that include <strong>the</strong> caregiver<br />
o Staff education: effects on patients or caregivers<br />
o Psychoeducation/psychosocial interventions for informal caregivers:<br />
effects on patients or caregivers<br />
o Respite care and special care units: effects on informal caregiver<br />
depression and stress<br />
o Interventions to delay institutionalization<br />
o Miscellaneous
