November 1, 2022 updated by: Shubashini Gnanasan, Universiti Teknologi Mara

Effects of Diffused Ylang-Ylang (Cananga Odorata) Essential Oil Amongst Older Persons With Dementia: A Pre-Post Quasi-Experimental Study Protocol

Ylang-Ylang (Cananga Odorata) essential oil has been postulated to have calming effect, which may improve BPSD in persons with dementia. This study aims to examine dementia-related behavioural changes using established assessment tools and brain derived neurotropic factor (BDNF) in persons with BPSD.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Behavioural and Psychological Symptoms of Dementia (BPSD) refers to the spectrum of non-cognitive and non-neurological symptoms of dementia, such as agitation, psychosis, depression and apathy. Ylang-Ylang (Cananga Odorata) essential oil is postulated to have calming effect, which may improve BPSD in persons with dementia. Thus, this study aims to examine dementia-related behavioural changes using established assessment tools and brain derived neurotropic factor (BDNF) in persons with BPSD. A pre-post quasi-experimental pilot study will be conducted over a two-month period in nursing homes with persons with dementia. Approximately 30 persons with dementia are expected to participate in this study. During the pre-intervention phase, water will be diffused using a diffuser in a common area of the nursing homes. During the intervention phase, Ylang-Ylang essential oil will be diffused using the identical diffuser over the same common area. Both water and essential oil will be diffused twice a day, each for a duration of 20 min during the respective phases. Observation and documentation of behavioural symptoms will be taken using validated instruments during the pre- and post-intervention phases. In addition, 10 mL of blood will also be collected at pre and post intervention for biochemical analyses.If Ylang-ylang essential oil were found to be beneficial based on the laboratory and observational findings, it can be possibly used as an alternative approach in managing BPSD.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Cornell Scale for Depression in Dementia
Time Frame: 2 months
The mean counts of this parameter before and after intervention phase will be analysed using Cornell Scale for Depression in Dementia. The score more than 18 means the persons is having definite major depressive episode.
2 months
Cohen-Mansfield Agitation Inventory
Time Frame: 2 months
The mean counts of this parameter before and after the intervention phase will be analysed using Cohen-Mansfield Agitation Inventory. A rating of five indicates that the person is having frequent agitation within an hour.
2 months
Neuropsychiatric Inventory- Brief Questionnaire Form
Time Frame: 2 months
The mean counts of this parameter before and after the intervention phase will be analysed using the Neuropsychiatric Inventory- Brief Questionnaire Form. A person is undergoing severe symptoms of BPSD if the score is 3, while caregivers are undergoing more distress when the score is 5.
