    Input: OBJECTIVE To determine the effectiveness of community based occupational therapy on daily functioning of patients with dementia and the sense of competence of their care givers . DESIGN Single blind r and omised controlled trial . Assessors were blinded for treatment allocation . SETTING Memory clinic and day clinic of a geriatrics department and participants ' homes . PARTICIPANTS 135 patients aged > or = 65 with mild to moderate dementia living in the community and their primary care givers . INTERVENTIONS 10 sessions of occupational therapy over five weeks , including cognitive and behavioural interventions , to train patients in the use of aids to compensate for cognitive decline and care givers in coping behaviours and supervision . MAIN OUTCOME MEASURES Patients ' daily functioning assessed with the assessment of motor and process skills ( AMPS ) and the performance scale of the interview of deterioration in daily activities in dementia ( IDDD ) . Care giver burden assessed with the sense of competence question naire ( SCQ ) . Participants were evaluated at baseline , six weeks , and three months . RESULTS Scores improved significantly relative to baseline in patients and care givers in the intervention group compared with the controls ( differences were 1.5 ( 95 % confidence interval 1.3 to 1.7 ) for the process scale ; -11.7 ( -13.6 to -9.7 ) for the performance scale ; and ( 11.0 ; 9.2 to 12.8 ) for the competence scale ) . This improvement was still significant at three months . The number needed to treat to reach a clinical ly relevant improvement in motor and process skills score was 1.3 ( 1.2 to 1.4 ) at six weeks . Effect sizes were 2.5 , 2.3 , and 1.2 , respectively , at six weeks and 2.7 , 2.4 , and 0.8 , respectively , at 12 weeks . CONCLUSIONS Occupational therapy improved patients '  daily functioning and reduced the burden on the care giver , despite the patients ' limited learning ability . Effects were still present at 12 weeks , which justifies implementation of this intervention . TRIAL REGISTRATION Clinical Trials NCT00295152 [ Clinical Trials.gov ] AIM This paper reports a study to examine the effectiveness of a 6-month dementia care programme for Chinese families living with and caring for a relative with dementia , compared with routine family support services in Hong Kong . BACKGROUND Recognizing the adverse psychosocial health effects inherent in dementia care , different psychosocial interventions provided preliminary evidence of their effectiveness in improving family members ' knowledge and skills in caregiving and delaying dementia sufferers ' illness deterioration and institutionalization . Little is known about the effects of such interventions for family caregivers ' psychosocial health conditions , particularly in non-Western population s. METHODS A r and omized controlled trial was conducted with 92 Chinese families of a relative with dementia in two dementia care centres in Hong Kong . They were r and omly selected from a dementia client list and then r and omly assigned to receive either the dementia family care programme ( n=46 ) , or routine care only ( n=46 ) . Clients ' symptoms and institutionalization , and caregivers ' quality of life , burden and social support at recruitment , 1 week , and 12 and 18 months following intervention were measured and compared between the study groups using repeated measures MANOVAS followed by Helmert 's contrast tests . Data was collected over a period of 24 months , between September 2007 and August 2009 . RESULTS Results of the MANOVAS and contrast tests indicated that at 18-month follow-up , participants in the family programme reported significantly greater improvements in clients ' symptoms and institutionalization rates , and caregivers ' quality of life and burden , when compared with their counterparts in the routine care group . CONCLUSION These findings provide evidence that the dementia care family programme can improve the psychosocial functioning of both clients with dementia and their family caregivers in a Chinese population . Further research is recommended to investigate whether this intervention can also apply to families with different socio-economic background s and across cultures All dementia patients and their caregivers who had received a University-based comprehensive evaluation and a diagnosis of Alzheimer 's disease during 1997 ( N = 80 ) were surveyed 1 year after their initial assessment . Of the original cohort , 72.5 % were contacted , and two subgroups were defined : 31 patients were being seen only by their primary care physicians ( MED ) , and 27 patients were being treated in addition by a geriatric psychiatry faculty member ( GERO ) . There were statistically significant differences between the two groups ( MED vs. GERO , respectively ) at follow-up in terms of : 1 ) hospitalization ( 39 % vs. 15 % ; P < O.05 ) ; 2 ) cognitive status ( P < O.05 ) ; and 3 ) prescription of donepezil  at follow-up ( 35 % vs. 64 % ; P < O. 005 ) . These differences need to be assessed in a larger-scale prospect i ve study OBJECTIVES To provide evidence regarding the clinical efficacy of cognitive rehabilitation ( CR ) in early-stage Alzheimer disease ( AD ) . DESIGN Single-blind r and omized controlled trial comparing CR with relaxation therapy and no treatment . SETTING Outpatient , community-based setting . PARTICIPANTS Sixty-nine individuals ( 41 women , 28 men ; mean age 77.78 years , st and ard deviation 6.32 , range = 56 - 89 ) with a diagnosis of AD or mixed AD and vascular dementia and a Mini-Mental State Examination score of 18 or above , and receiving a stable dose of acetylcholinesterase-inhibiting medication . Forty-four family carers also contributed . INTERVENTION Eight weekly individual sessions of CR consisting of personalized interventions to address individually relevant goals supported by components addressing practical aids and strategies , techniques for learning new information , practice in maintaining attention and concentration , and techniques for stress management . MEASUREMENTS The primary outcomes were goal performance and satisfaction , assessed using the Canadian Occupational Performance Measure . Question naires assessing mood , quality of life and career strain , and a brief neuropsychological test battery were also administered . A subset of participants underwent functional magnetic resonance imaging ( fMRI ) . RESULTS CR produced significant improvement in ratings of goal performance and satisfaction , whereas scores in the other two groups did not change . Behavioral changes in the CR group were supported by fMRI data for a subset of participants . CONCLUSIONS The findings support the clinical efficacy of CR in early-stage AD . CR offers a means of assisting people with early-stage AD and their families in managing the effects of the condition CONTEXT Optimal treatment to postpone functional decline in patients with dementia is not established . OBJECTIVE To test a nonpharmacologic intervention realigning environmental dem and s with patient capabilities . DESIGN , SETTING , AND PARTICIPANTS Prospect i ve 2-group r and omized trial ( Care of Persons with Dementia in their Environments [ COPE ] ) involving patients with dementia and family caregivers ( community-living dyads ) recruited from March 2006 through June 2008 in Pennsylvania . INTERVENTIONS Up to 12 home or telephone contacts over 4 months by health professionals who assessed patient capabilities and deficits ; obtained blood and urine sample s ; and trained families in home safety , simplifying tasks , and stress reduction . Control group caregivers received 3 telephone calls and educational material s. MAIN OUTCOME MEASURES Functional dependence , quality of life , frequency of agitated behaviors , and engagement for patients and well-being , confidence using activities , and perceived benefits for caregivers at 4 months . RESULTS Of 284 dyads screened , 270 ( 95 % ) were eligible and 237 ( 88 % ) r and omized . Data were collected from 209 dyads ( 88 % ) at 4 months and 173 ( 73 % ) at 9 months . At 4 months , compared with controls , COPE patients had less functional dependence ( adjusted mean difference , 0.24 ; 95 % CI , 0.03 - 0.44 ; P = .02 ; Cohen d = 0.21 ) and less dependence in instrumental activities of daily living ( adjusted mean difference , 0.32 ; 95 % CI , 0.09 - 0.55 ; P = .007 ; Cohen d = 0.43 ) , measured by a 15-item scale modeled after the Functional Independence Measure ; COPE patients also had improved engagement ( adjusted mean difference , 0.12 ; 95 % CI , 0.07 - 0.22 ; P = .03 ; Cohen d = 0.26 ) , measured by a 5-item scale . COPE caregivers improved in their well-being ( adjusted mean difference in Perceived Change Index , 0.22 ; 95 % CI , 0.08 - 0.36 ; P = .002 ; Cohen d = 0.30 ) and confidence using activities ( adjusted mean difference , 0.81 ; 95 % CI , 0.30 - 1.32 ; P = .002 ; Cohen d = 0.54 ) , measured by a 5-item scale . By 4 months , 64 COPE dyads ( 62.7 % ) vs 48 control group dyads ( 44.9 % ) eliminated 1 or more caregiver-identified problems ( chi(2/1 ) = 6.72 , P = . 01 ) . CONCLUSION Among community-living dyads , a nonpharmacologic biobehavioral environmental intervention compared with control result ed in better outcomes for COPE dyads at 4 months . Although no group differences were observed at 9 months for patients , COPE caregivers perceived greater benefits . TRIAL REGISTRATION clinical trials.gov Identifier : NCT00259454 BACKGROUND Reality orientation therapy combined with cholinesterase inhibitors has not been evaluated in patients with Alzheimer 's disease . AIMS To perform such an evaluation . METHOD We r and omly 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 . RESULTS 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 . CONCLUSIONS Reality orientation enhances the effects of donepezil on cognition in Alzheimer 's disease PURPOSE OF STUDY The authors determined short-term effects of a home environmental intervention on self-efficacy and upset in caregivers and daily function of dementia patients . They also determined if treatment effect varied by caregiver gender , race , and relationship to patient . DESIGN AND METHODS Families ( N = 171 ) of dementia patients were r and omized to intervention or usual care control group .  The intervention involved 5 90-min home visits by occupational therapists who provided education and physical and social environmental modifications . RESULTS Compared with controls , intervention caregivers reported fewer declines in patients ' instrumental activities of daily living ( p = .030 ) and less decline in self-care and fewer behavior problems in patients at 3 months post-test . Also , intervention spouses reported reduced upset ( p = .049 ) , women reported enhanced self-efficacy in managing behaviors ( p = .038 ) , and women ( p = .049 ) and minorities ( p = .037 ) reported enhanced self-efficacy in managing functional dependency . IMPLICATION S The environmental program appears to have a modest effect on dementia patients ' IADL dependence . Also , among certain subgroups of caregivers the program improves self-efficacy and reduces upset in specific areas of caregiving CONTEXT Most older adults with dementia will be cared for by primary care physicians , but the primary care practice environment presents important challenges to providing quality care . OBJECTIVE To test the effectiveness of a collaborative care model to improve the quality of care for patients with Alzheimer disease . DESIGN , SETTING , AND PATIENTS Controlled clinical trial of 153 older adults with Alzheimer disease and their caregivers who were r and omized by physician to receive collaborative care management ( n = 84 ) or augmented usual care ( n = 69 ) at primary care practice s within 2 US university-affiliated health care systems from January 2002 through August 2004 . Eligible patients ( identified via screening or medical record ) met diagnostic criteria for Alzheimer disease and had a self-identified caregiver . INTERVENTION Intervention patients received 1 year of care management by an interdisciplinary team led by an advanced practice nurse working with the patient 's family caregiver and integrated within primary care . The team used st and ard protocol s to initiate treatment and identify , monitor , and treat behavioral and psychological symptoms of dementia , stressing nonpharmacological management .
