About this study
Official title: Cognitive Stimulation and Memory Enhancement Through Virtual Reality in Patients With Alzheimer's Disease: A Behavioral, Biometric, and Neurocognitive Assessment
This study aims to evaluate whether immersive virtual reality (VR) can improve cognitive function and memory in patients with Alzheimer's disease. Twenty participants in Burgos, Spain, will engage in VR sessions that recreate scenes from 1960s Burgos, representing environments familiar from the participants' youth. The effects of these VR-based cognitive stimulation sessions will be assessed through pre- and post-intervention evaluations, including behavioral observations, EEG monitoring of brain activity, and standardized neurocognitive tests (Montreal Cognitive Assessment, Clock-Drawing Test, and Verbal Fluency Test).
Read the detailed description
Introduction: Alzheimer's disease is a neurodegenerative condition characterized by progressive cognitive decline. Virtual reality (VR) technologies offer an innovative approach to cognitive stimulation in patients with this condition. This study will evaluate the impact of VR on memory and cognition improvement in patients with Alzheimer's disease in Burgos.
Objective: Evaluate the effectiveness of cognitive and memory stimulation through virtual reality experiences in patients with Alzheimer's disease, using behavioral analysis, biometric data (EEG), and neurocognitive testing.
Methodology: A total of 20 patients diagnosed with Alzheimer's disease at a specialized center in Burgos will be selected. The patients will be exposed to virtual reality scenarios recreating the city of Burgos in the 1960s, a period corresponding to their youth. Their cognitive and emotional status will be assessed before and after the sessions using neurocognitive tests, behavioral monitoring, and biometric data recording (EEG). Analyses of variance (ANOVA), analyses of covariance (ANCOVA), and multivariate analyses of variance (MANOVA) were perfomed

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Virtual realityOther
The intervention consists of a series of immersive virtual reality (VR) sessions designed to provide cognitive stimulation for patients diagnosed with Alzheimer's disease. Participants in the experimental group will be exposed to VR environments that recreate the city of Burgos as it appeared in the 1960s, an era corresponding to their youth. These VR experiences will include familiar scenes, landmarks, and culturally relevant settings designed to evoke personal memories and enhance cognitive engagement.
| Study group | Role | What they receive |
|---|---|---|
| Experimental group | Experimental | The sample consisted of 33 people: 16 in the experimental group. Receives: Other: Virtual reality |
| Control group | No intervention | The sample consisted of 33 people: 17 in the control group. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Cognitive Function (Montreal Cognitive Assessment - MoCA)
Change in cognitive function will be assessed using the Montreal Cognitive Assessment (MoCA). The MoCA evaluates multiple cognitive domains, including memory, attention, language, executive function, and visuospatial abilities. Total scores range from 0 to 30, with higher scores indicating better cognitive function. The change score will be calculated as the post-intervention score minus the baseline score.
Measured: Baseline and immediately after the last virtual reality session
Secondary outcomes (7)
Change in emotional well-being assessed with the Satisfaction With Life Scale (SWLS)
Change in emotional well-being will be assessed using the Satisfaction With Life Scale (SWLS). The SWLS is a 5-item scale that assesses global life satisfaction. Total scores range from 5 to 35, with higher scores indicating greater satisfaction with life and better emotional well-being. The change score will be calculated as the post-intervention score minus the baseline score.
Measured: Baseline and immediately after the last virtual reality session
Change in Verbal Fluency (Verbal Fluency Test)
Change in the number of words generated in a 60-second period, assessing language and cognitive processing speed.
Measured: Baseline and post-intervention.
Change in attention and processing speed
Attention, visual scanning, and processing speed will be assessed using the Trail Making Test Part A. The outcome will be the time required to complete the task. Lower completion times indicate better performance.
Measured: Baseline and immediately after the last virtual reality session
Change in executive function and cognitive flexibility assessed with the Trail Making Test Part B (TMT-B)
Executive function and cognitive flexibility will be assessed using the Trail Making Test Part B. The outcome will be the time required to complete the task. Lower completion times indicate better performance.
Measured: Baseline and immediately after the last virtual reality session
Change in positive affect assessed with the Positive and Negative Affect Schedule Short Form (PANAS-S)
Positive affect will be assessed using the positive affect subscale of the Positive and Negative Affect Schedule Short Form (PANAS-S). Higher scores indicate greater positive affect.
Measured: Baseline and immediately after the last virtual reality session.
Change in negative affect assessed with the Positive and Negative Affect Schedule Short Form (PANAS-S)
Negative affect will be assessed using the negative affect subscale of the Positive and Negative Affect Schedule Short Form (PANAS-S). Higher scores indicate greater negative affect.
Measured: Baseline and immediately after the last virtual reality session
Immediate emotional response assessed with an Emotional Visual Analog Scale
Immediate emotional response will be assessed after each intervention session using an Emotional Visual Analog Scale ranging from 0 to 10, where higher scores indicate a more positive emotional state.
Measured: Baseline and immediately after the last virtual reality session

Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Cognitive Function (Montreal Cognitive Assessment - MoCA) (time frame: Baseline and immediately after the last virtual reality session). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07645638, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
