Visual art therapy and its effects in older people with mild cognitive impairment: A systematic review

Abstract Introduction Mild cognitive impairment (MCI) is a known risk factor for the development of dementia. The potential benefits on cognition from non‐pharmacological measures such as art‐based interventions are of increasing interest. This systematic review examines the evidence for the impact of one form of art‐based intervention, visual art therapy (VAT), on the cognition and psychological wellbeing of older people with MCI. Methods Randomised controlled and quasi‐experimental trials evaluating the efficacy of VAT in older persons aged over 60 years with MCI were included. A search was performed on electronic databases: MEDLINE, CINAHL, Embase and PsycINFO. Joanna Briggs Institute critical appraisal and extraction tools were utilised for risk of bias assessment and data extraction, respectively. A narrative descriptive approach was used to outline the findings. Results Seven studies were identified from 4311 articles screened. Improvement in cognition was reported in five studies, with two of these reporting sustained improvement at 6–9 months, while the remaining three studies showed improvement only at the immediate post‐intervention period. A positive impact was reported in four of six studies that examined the effect of VAT on participant psychological wellbeing. The overall methodological quality of the studies ranged from moderate in four of five RCTs, to high in the quasi‐experimental studies and one RCT. However, the low study power in the context of small sample sizes limits the applicability of these studies to the population of interest. Conclusions VAT is potentially an effective non‐pharmacological intervention that may enhance cognition and provide benefits for psychological wellbeing in older persons with MCI. Given the limited studies available, with the majority emerging over the last 5 years, further research is required to confirm these reported benefits, as well as to determine whether VAT impacts on the progression of cognitive decline in MCI.
