This randomized study evaluated the combined effect of a cognitive-communication program plus an acetylcholinesterase inhibitor (donepezil; donepezil-plus-stimulation group; n = 26), as compared with donepezil alone (donepezil-only group; n = 28) in 54 patients with mild to moderate Alzheimer's disease (AD; Mini-Mental Status Examination score of 12- 28) ranging in age from 54 to 91 years. It was hypothesized that cognitive-communication stimulation in combination with donepezil would positively affect the following: (a) relevance of discourse, (b) performance of functional abilities, (c) emotional symptoms, (d) quality of life, and (e) overall global function, as measured by caregiver and participant report and standardized measures. Cognitive-communication, neuropsychiatric, functional performance, and quality of life evaluations were conducted at baseline and Month 4, the month after the 2-month active stimulation period. Follow-up evaluations were performed at Months 8 and 12. The stimulation program consisted of 12 hr of intervention over an 8-week period and involved participant-led discussions requiring homework, interactive sessions about AD, and discussions using salient life stories. Additive effects of active stimulation with donepezil were examined in 2 ways: (1) comparing mean group performance over time and (2) evaluating change scores from baseline. A Group x Time interaction was found for the donepezil-plus-stimulation group in the emotional symptoms of apathy and irritability as compared with the donepezil-only group. Evaluation of change scores from baseline to 12 months revealed a positive effect for the donepezil-plus-stimulation group on discourse and functional abilities with a trend on apathy, irritability, and patient-reported quality of life. In sum, the research revealed benefits to the donepezil-plus-stimulation group in the areas of discourse abilities, functional abilities, emotional symptoms, and overall global performance. This study adds to growing evidence that active cognitive stimulation may slow the rate of verbal and functional decline and decrease negative emotional symptoms in AD when combined with acetylcholinesterase inhibitors, indicating a need to advance research in the area of cognitive treatments. The fact that AD is a progressive brain disease should not preclude ameliorative treatment. To study the efficacy of cognitive rehabilitation combined with acetylcholinesterase inhibitor (AChE-I) treatment in patients with mild Alzheimer's disease and their relatives.
                Thirteen patients with mild Alzheimer's disease treated with rivastigmine 6-12 mg/day for more than two months started cognitive rehabilitation training. Before and after the cognitive rehabilitation training patients were assessed through cognitive tests, activities of daily living scale, neuropsychological battery and scales to evaluate caregivers' depressive and anxiety symptoms. Six patients were randomized to a combined treatment group (AChE-I plus cognitive rehabilitation and caregiver support) and seven patients to a control group (AChE-I only) and followed up for five months.
                Mini-Mental State Examination (MMSE) scores (p = 0.047) and backward digit span scores (p = 0.018) were significantly different between the groups on follow-up. The combined treatment group showed a better positive treatment effect on cognitive and neuropsychological tests applied to patients and reduction of psychiatric symptoms was observed in their caregivers (nonsignificant).
                Cognitive rehabilitation associated with AChE-I treatment can potentially be useful to stabilize or improve cognitive and functional performance of patients with mild Alzheimer's disease and can reduce caregivers' psychiatric symptoms. Reality orientation therapy combined with cholinesterase inhibitors has not been evaluated in patients with Alzheimer's disease.
                To perform such an evaluation.
                We randomly assigned 79 of 156 patients treated with donepezil to receive a reality orientation programme. Caregivers of the treatment group were trained to offer the programme at home 3 days a week, 30 min/day, for 25 consecutive weeks, and were invited to stimulate and involve patients in reality-based communication.
                The treatment group showed a slight improvement in Mini-Mental State Examination (MMSE) scores (mean change +0.2, s.e.=0.4) compared with a decline in the control group (mean change -1.1, s.e.=0.4; P=0.02). Similarly for the Alzheimer's Disease Assessment Scale--Cognition (treatment group mean change +0.4, s.e.=0.8; control group -2.5, s.e.=0.8; P=0.01). The intervention had an equal effect on cognition in those with mild (MMSE score > or = 20) and moderate (score <20) dementia. No significant effect was observed for behavioural and functional outcomes.
                Reality orientation enhances the effects of donepezil on cognition in Alzheimer's disease. nan Recent studies have shown that patients with Alzheimer's disease (AD) and its possible prodromal stage mild cognitive impairment benefit from cognitive interventions. Few studies so far have used an active control condition and determined effects in different stages of disease. We evaluated a newly developed 6-month group-based multicomponent cognitive intervention in a randomized controlled pilot study on subjects with amnestic mild cognitive impairment (aMCI) and mild AD patients. Forty-three subjects with aMCI and mild AD were recruited. Primary outcome measures were change in global cognitive function as determined by the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) and the Mini Mental Status Examination (MMSE). Secondary outcomes were specific cognitive and psychopathological ratings. Thirty-nine patients were randomized to intervention groups (IGs: 12 aMCI, 8 AD) and active control groups (CGs: 12 aMCI, 7 AD). At the end of the study, we found significant improvements in the IG(MCI) compared to the CG(MCI) in the ADAS-cog (p = 0.02) and for the secondary endpoint Montgomery Asberg Depression Rating Scale (MADRS) (p < 0.01) Effects on the MMSE score showed a non-significant trend (p = 0.07). In AD patients, we found no significant effect of intervention on the primary outcome measures. In conclusion, these results suggest that participation in a 6-month cognitive intervention can improve cognitive and non-cognitive functions in aMCI subjects. In contrast, AD patients showed no significant benefit from intervention. The findings in this small sample support the use of the intervention in larger scales studies with an extended follow-up period to determine long-term effects. A trial was carried out of Reality Orientation (R.O.) in a residential home for the elderly mentally infirm with a 'social therapy' control group, receiving the same amount of staff attention as the R.O. group, in addition to an untreated control group. R.O. residents improved more on tests of information and orientation and various aspects of memory than controls. These results support the hypothesis that the nature of staff attention is crucial and that it should encourage and reward appropriate behaviour. No differential effects of treatment were found on rating scale assessments of the resident's functioning in the home. We compared reality orientation with reminiscence therapy for elderly people in a large residential home, using a controlled cross-over design. Both kinds of therapy group were enjoyed by both staff and residents, and enabled staff to get to know moderately and severely confused residents. The group that received reality orientation followed by reminiscence therapy showed improvement in cognitive and behavioural measures which was not found in the other two groups. It may be important to use reality orientation techniques with confused residents before involving them in a reminiscence group. Sixty long-stay patients who were demented or withdrawn or both were randomly allocated to reality orientation or diversional occupational therapy and were assessed blind on two scales. Owing to a high drop-out rate only 19 organic and 19 functional patients satisfied reasonable criteria for inclusion in the analyses. Those treated by reality orientation therapy fared better than the controls but not significantly so. Initial test scores were no guide to outcome. The results suggested that both organic and functional patients benefited cognitively, but hardly at all behaviourally, from both types of treatment. Several studies have shown that pharmacological and cognitive treatments for Alzheimers's disease improve cognitive function for short periods, but fewer studies have evaluated the efficacy of those treatments for longer (2-year) periods. An initial sample of 68 subjects with mild Alzheimer's disease underwent clinical and cognitive evaluation. After evaluation, subjects were assigned to four different groups and participated in a 2-year follow-up study. Group 1 (n = 14) received combined drug and cognitive stimulation, group 2 (n = 20) received only drug treatment, group 3 (n = 14) received only cognitive stimulation, and group 4 (n = 30) received no treatment at all. Results confirmed previous investigation, cognitive and combined stimulation improved patients' performance throughout the 1st year; however, all groups deteriorated gradually throughout the 2nd year of treatment. According to this evidence, it can be concluded that we cannot stop cognitive deterioration after 2 years of treatment, although deterioration is greater and its progress faster in patients not receiving any treatment at all.
                Copyright (c) 2006 S. Karger AG, Basel. 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. Twenty-three institutionalized subjects, confused and disoriented as to time, space and persons, were divided into two groups: the study group and the control group. The study group then participated in a 3-month period of formal Realithy Orientation Therapy (ROT). At the end of the 3 months of therapy significant differences emerged in the scores of MMSE, OSGP and GDS obtained by the two groups. Moreover, significant positive differences were observed only in the study group, comparing the tests' results before and after therapy. Even the comparison of the results obtained at the end of the sessions and 3 months after the interruption of the therapy revealed a difference in the trends that emerged for the two groups.
