Apathy is a deficiency in overt behavioural, emotional and cognitive components of goal-directed behaviour. It is a common occurrence after traumatic brain injury (TBI), with widespread impact. We have systematically reviewed studies examining the effectiveness of interventions for apathy in the TBI population.
To investigate the effectiveness of interventions for apathy in adults who have sustained a TBI. This was evaluated by changes in behavioural, cognitive and emotional measures of apathy.
We searched the following databases up to January 2008: CENTRAL (The Cochrane Library 2008, Issue 1), Database of Abstracts of Reviews of Effects, ACP Journal Club, MEDLINE (1950 to Jan 2008), EMBASE (1980 to Jan 2008), PsycINFO (1806 to Jan 2008), CINAHL (1982 Jan 2008), PsycBITE, AMED (1985 to Jan 2008), www.controlled-trials.com, www.clinicaltrials.gov and www.actr.org.au.The Cochrane Injuries Group's Specialised Register was searched to Jan 2009. Additionally, we examined key conference proceedings and reference lists of included trials to identify further studies meeting the inclusion criteria.
Randomised controlled trials (RCTs) of interventions specifically targeting apathy for people with TBI.
Data collection and analysis
Two authors (ALB and RLT) independently assessed studies for inclusion. We rated the methodological quality of included studies and extracted data.
We identified one trial that satisfied the inclusion criteria for this review. This trial (N = 21) showed that cranial electrotherapy stimulation (CES) decreased inertia, which is a component of apathy, while no changes were seen in the sham treatment or no treatment control groups. Given that no between-group analysis was reported, it was not possible to determine if the CES treatment group improved significantly more than the control group.
No evidence was provided to support the use of CES treatment for inertia, a component of apathy. Between-group statistical analyses were not conducted and it was therefore not possible to determine the efficacy of the treatment relative to no treatment or sham treatment. Results regarding the effectiveness of treatment can only be inferred, and this evidence is based on only one trial with a small sample size. More randomised controlled trials evaluating different ways of treating apathy would be valuable. Trials should have larger sample sizes and use rigorous research designs and statistical analyses appropriate for examining between-group differences.
Plain language summary
Treatment for apathy in people with traumatic brain injury
Many people who have a traumatic brain injury experience apathy. Apathy is a decrease in cognitive, behavioural and emotional components of goal-directed activity due to reduced motivation. It is characterised by lessened activity, initiative and concern about working towards and achieving goals. This problem impacts on rehabilitation outcome, independence, work and family burden.
The review authors searched the literature for treatment studies of apathy, or a component of apathy, in people who have had a traumatic brain injury. One randomised controlled trial was found which examined the use of cranial electrotherapy stimulation for inertia, which is a component of apathy. Evidence for the effectiveness of this treatment is particularly restricted by the small number of participants and the lack of statistical analyses to demonstrate that the cranial electrotherapy stimulation treatment was more successful than sham or no treatment. More methodologically rigorous studies need to be conducted to investigate different methods of effectively treating apathy in people with traumatic brain injury.
我們搜索了以下資料庫至2008年1月：CENTRAL (The Cochrane Library 2008, Issue 1), Database of Abstracts of Reviews of Effects, ACP Journal Club, MEDLINE (1950 to Jan 2008), EMBASE (1980 to Jan 2008), PsycINFO (1806 to Jan 2008), CINAHL (1982 Jan 2008), PsycBITE, AMED (1985 to Jan 2008), www.controlledtrials.com, www.clinicaltrials.gov and www.actr.org.au。檢索The Cochrane Injuries Group's Specialised Register至2009年1月。此外，我們評估重要的會議記錄及蒐集研究的參考文獻以確認研究符合納入標準。
介入措施專門針對腦外傷人口其神情呆滯的隨機對照試驗(Randomised controlled trials (RCTs))。
我們確定了一項試驗，其符合本篇回顧的納入標準。這項試驗(N = 21)顯示，顱電刺激(cranial electrotherapy stimulation (CES))可以減少遲鈍，其為神情呆滯的組成部分，然而模擬治療或無治療之對照組則沒有變化。已知沒有進行組間分析的報告，因此不可能就此決定是否顱電刺激治療組較對照組有明顯的改善。
