A recent randomised controlled trial on Cognitive Stimulation Therapy (CST) identified the need to evaluate its more long-term benefits for people with dementia. This study evaluates the effectiveness of a weekly maintenance CST programme for people with dementia in residential care.
Thirty-five people with dementia were included, following on from a seven-week twice-weekly study of CST. The maintenance CST sessions ran in two residential homes using a once a week programme of CST over an additional 16 weeks. Two control homes did not receive the maintenance intervention.
Using repeated measures ANOVAS, there was a continuous, significant improvement in cognitive function (MMSE) for those receiving MCST (CST+maintenance CST sessions) as compared to CST alone or no treatment (p = 0.012). There were no effects on quality of life, behaviour or communication following maintenance sessions. The initial cognitive improvements following CST were only sustained at follow-up when followed by the programme of maintenance CST sessions.
The cognitive benefits of CST can be maintained by weekly sessions for around 6 months. A large-scale, multi-centre maintenance CST trial is required to clarify potential longer-term benefits of maintenance CST for dementia.
最近一项关于认知刺激疗法(CST)的随机对照试验表明,有必要评估其对痴呆症患者更长期的益处。本研究评估了针对住院护理痴呆症患者的每周一次维持性CST计划的有效性。
在一项为期七周、每周两次的CST研究之后,纳入了35名痴呆症患者。维持性CST课程在两个养老院进行,采用每周一次的CST计划,为期16周。两个对照养老院未接受维持性干预。
使用重复测量方差分析,与单独接受CST或不接受治疗相比,接受MCST(CST+维持性CST课程)的患者认知功能(MMSE)持续显著改善(p = 0.012)。维持性课程对生活质量、行为或沟通没有影响。CST后的初始认知改善仅在后续进行维持性CST课程时在随访中得以维持。
CST的认知益处可通过每周一次的课程维持约6个月。需要进行大规模、多中心的维持性CST试验,以阐明维持性CST对痴呆症潜在的长期益处。
