To date, no firm conclusions can be reached regarding the effectiveness of reminiscence for dementia. Researchers have emphasized that there is an urgent need for more systematic research in the area.
                A single-blinded, parallel-groups (one intervention, one comparison, and one no-intervention group) randomized controlled trial (RCT) was adopted to investigate whether a specific reminiscence program leads to higher levels of psychosocial well-being in nursing home residents with dementia. The intervention adopted a life-story approach, while the comparison group provided friendly discussions to control for any changes in outcome as a result of social contacts and attention. The Social Engagement Scale (SES) and Well-being/Ill-being Scale (WIB) were the outcome measures used. The outcomes of the groups were examined with reference to the baseline (T0), immediately (T1), and six weeks (T2) after intervention. The final sample had 101 subjects (control group: n=30; comparison group: n=35; intervention group: n = 36). Using multivariate analysis with repeated measures, no significant differences in outcome were found between groups at either T1 or T2. Wilcoxon signed rank tests were performed for each group comparing outcomes between T1 and T0, T2 and T1, and T2 and T0. Significant differences were observed in the intervention group when comparing T1 and T0 WIB (p = .014), but not for the other groups.
                Although the intervention did not lead to significant differences between the three groups over time, there was a significant improvement in psychosocial well-being for the intervention group. Twenty-seven demented elderly nursing home residents were given either reminiscence group therapy or supportive group therapy or were assigned to a no-treatment control group. The self-reported level of depression in participants given reminiscence therapy was positively affected compared to participants in the supportive therapy and control groups, but no significant effects were found for cognitive or behavioral functioning. Results are discussed in terms of the issue of the applicability of reminiscence therapy for cognitively impaired persons, the appropriateness of the measures used in this study to assess depression, cognitive ability and behavioral functioning, and in conjunction with clinical observations made during the process of therapy. A recent Cochrane review of reality orientation therapy identified the need for large, well-designed, multi-centre trials.
                To test the hypothesis that cognitive stimulation therapy (CST) for older people with dementia would benefit cognition and quality of life.
                A single-blind, multi-centre, randomised controlled trial recruited 201 older people with dementia. The main outcome measures were change in cognitive function and quality of life. An intention-to-treat analysis used analysis of covariance to control for potential variability in baseline measures.
                One hundred and fifteen people were randomised within centres to the intervention group and 86 to the control group. At follow-up the intervention group had significantly improved relative to the control group on the Mini-Mental State Examination (P=0.044), the Alzheimer's Disease Assessment Scale - Cognition (ADAS-Cog) (P=0.014) and Quality of Life - Alzheimer's Disease scales (P=0.028). Using criteria of 4 points or more improvement on the ADAS-Cog the number needed to treat was 6 for the intervention group.
                The results compare favourably with trials of drugs for dementia. CST groups may have worthwhile benefits for many people with dementia. The evidence for the effectiveness of memory rehabilitation is inconclusive. The aim was to compare the effectiveness of two group memory rehabilitation programmes with a self-help group control.
                Single-blind randomized controlled trial.
                Participants with memory problems following traumatic brain injury, stroke or multiple sclerosis were recruited from community settings.
                Participants were randomly allocated, in cohorts of four, to compensation or restitution group treatment programmes or a self-help group control. All programmes were manual-based and comprised two individual and ten weekly group sessions.
                Memory functions, mood, and activities of daily living were assessed at baseline and five and seven months after randomization.
                There were 72 participants (mean age 47.7, SD 10.2 years; 32 men). There was no significant effect of treatment on the Everyday Memory Questionnaire (P = 0.97). At seven months the mean scores were comparable (restitution 36.6, compensation 41.0, self-help 44.1). However, there was a significant difference between groups on the Internal Memory Aids Questionnaire (P = 0.002). The compensation and restitution groups each used significantly more internal memory aids than the self-help group (P < 0.01). There were no statistically significant differences between the groups on measures of mood, adjustment and activities of daily living (P > 0.05).
                There results show few statistically significant effects of either compensation or restitution memory group treatment as compared with a self-help group control. Further randomized trials of memory rehabilitation are needed. Research on the management and the outcome of treatment of medically unexplained symptoms is very limited. Development of simple but effective techniques for treatment and demonstration of their effectiveness when applied in primary health care are needed.
                A randomized controlled trial was carried out with follow-up assessments at 3 months after baseline assessments using the Short Explanatory Model Interview (SEMI), General Health Questionnaire (GHQ-30), Bradford Somatic Inventory (BSI) and patient satisfaction on a visual analogue scale. The study was carried out in a general out-patient clinic in Sri Lanka. The intervention group received six, 30 min sessions based on the principles of cognitive behavioural therapy over a period of 3 months. The control group received standard clinical care.
                Eighty patients out of the 110 patients referred, were eligible. Sixty-eight were randomly allocated equally to the control and treatment groups. All 34 in the treatment group accepted the treatment offer and 22 completed between three and six sessions. At 3 months, 24 in the treatment and 21 in the control group completed follow-up assessments. Intention-to-treat analysis revealed significant differences in mean scores of outcome measures (adjusted for baseline scores) between control and intervention groups respectively--complaints 6.1 and 3.8 (P = 0.001), GHQ 10.4 and 6.3 (P = 0.04), BSI score 15.6 and 132 (P < 0-01), visits 7.9 and 3.1 (P = 0.004).
                Intervention based on cognitive behavioural therapy is feasible and acceptable to patients with medically unexplained symptoms from a general out-patients clinic in Sri Lanka. It had a significant effective in reducing symptoms, visits and distress, and in increasing patient satisfaction. Research on non-pharmacological therapies (cognitive rehabilitation) in old age has been very limited, and most has not considered the effect of interventions of this type over extended periods of time.
                To investigate a new cognitive therapy in a randomized study with elderly people who did not suffer cognitive impairment.
                The efficacy of this therapy was evaluated by means of post-hoc analysis of 238 people using biomedical, cognitive, behavioural, quality of life (QoL), subjective memory, and affective assessments.
                Scores for learning potential and different types of memory (working memory, immediate memory, logic memory) for the treatment group improved significantly relative to the untreated controls.
                The most significant finding in this study was that learning potential continued at enhanced levels in trained subjects over an intervention period lasting two years, thereby increasing rehabilitation potential and contributing to successful ageing. Cognitive compromise is one of the main contributing factors to activity and participation restrictions in people with multiple sclerosis (MS). Computer-aided programs are used for retraining memory and attention, but data on the efficacy of these interventions are scarce.
                To assess the efficacy of computer-aided retraining of memory and attention in people with MS impaired in these abilities.
                Randomized, double-blind, controlled trial.
                Outpatients (n=82) with subjective complaints of poor attention or memory, confirmed by a score <80th percentile in at least two tests of the Brief Repeatable Battery of Neuropsychological Tests (BRBNT).
                Participants were randomized to two computer-assisted retraining interventions: memory and attention (study arm), and visuo-constructional and visuo-motor coordination (control arm). Both groups received 16 training sessions over 8 weeks.
                Improvement of 20% or more in at least two BRBNT test scores at 8 weeks compared to baseline (primary end point). Changes in depression and health-related quality of life.
                An improvement occurred in 45% of study patients vs. 43% of control patients (odds ratio 1.07, 95% confidence interval 0.44-2.64). The study treatment was better than the control treatment only on the word list generation test (p=0.016).
                This trial does not support the efficacy of specific memory and attention retraining in MS. Dementia is a highly invalidating condition and, given the progressive aging of the population, one of the major issues that health systems will have to face in future years. Recently there has been an increase in the potential of diagnostic tools and pharmacological treatments for dementia; moreover, considerable interest has been expressed regarding non pharmacological interventions. However, the current evidence in support of non pharmacological treatments in patients affected by dementia still does not allow to draw definitive conclusions on what is the most effective treatment to apply, largely because of methodological difficulties and limitations of the studies so far carried out due to the complex nature of the disease. To address this need, we carried out a single blind randomized controlled study on the efficacy of computer cognitive rehabilitation in patients with mild cognitive decline. We here present preliminary data on 11 patients with diagnosis of Alzheimer's Disease (AD) and mild cognitive decline randomly assigned to treatment (a) or control (b) condition (i.e. specific vs. aspecific treatment). The specific treatment (a) consisted in a cycle of 12 individual sessions of computer exercises, while the control condition (b) consisted in sessions of semi-structured interviews with patients, conducted with the same frequency and time period as (a). Cognitive, behavioural and functional assessment was performed by an expert evaluator, blinded to the patients' group allocation. Preliminary results show a significant performance decline only in the control group at the 9-month follow-up compared to both baseline and the 3-month follow-up. Our results suggest that computer based cognitive training in patients with AD and mild cognitive decline is effective at least in delaying the continuous progression of cognitive impairment in AD. To investigate short-term effects of Multi-Sensory Stimulation (MSS) on behaviour, mood and cognition of older adults with dementia, the generalization of effects to day hospital and home environments and the endurance of any effects over time.
                A randomized controlled trial comparing MSS with a credible control of one-to-one activities.
                Fifty patients with diagnoses of moderate to severe dementia were randomized to either MSS or Activity groups. Patients participated in eight 30-minute sessions over a 4-week period. Ratings of behaviour and mood were taken before, during and after sessions to investigate immediate effects. Pre, mid, post-trial, and follow-up assessments were taken to investigate any generalization of effects on cognition, behaviour at the day hospital and behaviour and mood at home and endurance of effects once sessions had ceased.
                Immediately after MSS and Activity sessions patients talked more spontaneously, related better to others, did more from their own initiative, were less bored/inactive, and were more happy, active or alert. Both groups were more attentive to their environment than before, with a significantly greater improvement from the MSS group. At the day hospital, patients in the Activity group improved on their 'speech skills' (amount of speech; initiation of speech), whereas the MSS group remained unchanged during the trial. The MSS group showed a significant improvement in mood and behaviour at home compared to the Activity group whose behaviour deteriorated. No longer-term benefits were shown; indeed, behaviour declined sharply during the month follow-up period.
                Both MSS and Activity sessions appear to be effective and appropriate therapies for people with dementia.
Whilst four suitable randomized controlled trials looking at reminiscence therapy for dementia were found, several were very small studies, or were of relatively low quality, and each examined different types of reminiscence work. Although there are a number of promising indications, in view of the limited number and quality of studies, the variation in types of reminiscence work reported and the variation in results between studies, the review highlights the urgent need for more and better designed trials so that more robust conclusions may be drawn.
