AB  - BACKGROUND: Aromatherapy is a non-pharmacological therapy for the improvement of 
      dementia symptoms. This study aimed to assess the effects of aroma oil as a bath 
      salt on cognitive function, olfactory function and sleep quality. METHODS: This 
      was a randomised controlled trial. Overall, 49 patients were able to provide 
      consent, and 35 were finally analysed (Alzheimer's disease: 10, mild cognitive 
      impairment: 25). The patients were randomly assigned to use 0.1%, 0.5% or 1% 
      aroma bath salt. During daily bathing, bath salt was added to the bath water, and 
      the subjects remained in the bathroom for >/=10 min. The intervention period was 
      24 weeks, and the observation periods were 4 weeks before and after using the 
      aroma bath salt. We performed the Touch Panel-type Dementia Assessment Scale 
      (TDAS), the Odour Stick Identification Test for Japanese (OSIT-J) and the 
      Japanese version of the Pittsburgh Sleep Quality Index (PSQI-J) five times during 
      the before and after observation periods and after the 12-week intervention. 
      RESULTS: There were no significant changes in the TDAS, OSIT-J and PSQI-J scores 
      before and after the intervention in all groups. Moreover, there were no 
      significant differences in the TDAS, OSIT-J and PSQI-J scores between the groups 
      before and after the intervention. In the correlation analysis of changes in the 
      TDAS and other tests during the intervention period, significant associations 
      between TDAS and sleep latency and sleep disturbances, which are sub-items of 
      PSQI-J, were observed in the use of 0.1% aroma bath salt group. CONCLUSIONS: The 
      use of aroma bath salt was not associated with improvement in cognitive function, 
      olfactory function or sleep quality. However, sleep-related aspects were 
      associated with changes in cognitive function before and after use of aroma bath 
      salt, which suggested that there is a link between improvements in sleep and that 
      in cognitive function.
