Purpose: The present study was conducted with the aim of 
investigating the effectiveness of multisensory stimuli on 
mental state, clinical memory and sleep disorder in elderly 
women with cognitive impairment. 
Materials and Methods: The current research was conducted 
as a semi-experimental pre-test-post-test type with control and 
follow-up groups. The statistical population consisted of 30 
elderly women referring to nursing homes in Tehran, who 
were divided into two experimental and control groups by a 
simple random method. Questionnaires of mental state, 
clinical memory, sleep disorder and cognitive deficits were 
used to collect data. The data was analyzed using SPSS-21 
software and mixed analysis of variance tests. 
Findings: According to the results, multisensory stimulation 
had a significant effect on improving the mental state, clinical 
memory and sleep disorder in the elderly with cognitive 
deficits (P<0.01). Therefore, treatment of multisensory stimuli 
is effective on sleep disorder, mental state and clinical memory 
of the elderly (P<0.01). 
Conclusion: This method can be used to improve the cognitive 
ability and, as a result, the quality of life of the elderly 
independently and together with clinical and subclinical 
cognitive treatments.
