The Effect of Lavender Aromatherapy on Cognitive Function in Older Adults With Mild Cognitive Impairment
This trial is testing whether inhaling lavender scent helps older adults with Mild Cognitive Impairment (MCI) think more clearly, remember better, sleep better, and feel less anxious or depressed. Researchers will measure cognitive function before and after a 12-week aromatherapy program. This is a Phase NA (non-drug, non-approval-track) study — it is exploring whether a simple sensory intervention has measurable benefits, not testing a pharmaceutical.
You may qualify if
- The MCI mentioned in this study meets the diagnostic criteria proposed by the *Chinese Expert Consensus on the Diagnosis and Treatment of Alzheimer's Disease-Derived Mild Cognitive Impairment (2021)*: cognitive impairment reported by the patient or an informant, or identified by an experienced clinician; objective evidence of impairment in one or more cognitive domains, with episodic memory impairment being the most common; complex instrumental activities of daily living may be mildly impaired, but the ability to perform basic activities of daily living remains independent; the diagnostic criteria for dementia are not met.
- MoCA-Beijing version scores were adjusted for education level: ≤13 for junior high school education or below, ≤19 for high school education, and ≤24 for university education or above; MMSE score >24; ADL score \<23.
- Age between 60 and 79 years.
- Normal olfactory function assessed using the "Sniffin' Sticks" test.
- Ability to communicate normally and complete cognitive assessments.
- Residing in a senior care facility with no plans to leave within the next 12 weeks.
You're excluded if
- Presence of other conditions known to affect cognitive function, such as psychiatric disorders (e.g., schizophrenia, depression).
- History of asthma or any allergic conditions.
- Use of any prescription medications that may impact cognitive function (including psychotropic drugs and others)
