What is Cerebro Vivo?

Cerebro Vivo is a 4-session, Spanish-language cognitive health training program for Latino adults 55+ in Florida. It delivers culturally adapted education on memory, neuroplasticity, and dementia prevention alongside validated cognitive screening. The program is structured as a peer-reviewed research study — with a pre-registered protocol, IRB oversight, and 11 demographic variables designed to produce publishable community health data on an underrepresented population.

Cognitive Screening Battery

We use a hybrid administration model combining two validated instruments. The AD8 is administered online as a self-report questionnaire before sessions. The SBT is administered in-person by the trained facilitator at Session 4, following Washington University guidelines.

AD8
Ascertaining Dementia 8 · Galvin et al., Neurology 2005

Items8 yes/no — functional change domains
Duration~3 minutes

Specificity85.2% · AUC 0.843

AccessFree for clinical/community use
2025 Latino ValidationFirst validation study in US Latinos published September 2025 (Perales-Puchalt et al., University of Kansas ADRC). Spanish version outperformed English. Optimal cutoff revised to ≥3 (vs. standard ≥2). We apply this updated cutoff.
SBT

ProtocolWashU administration guidelines
Why in-person onlyItems 3 and 3b require memory registration and supervised delayed recall — which cannot be validly administered without a live facilitator. We use a hybrid model: AD8 online, SBT in-person at Session 4.

AD8 cutoff ≥3 per Perales-Puchalt et al. (2025) — first US Latino validation. Note: community screening tool, not a clinical diagnosis.


Methodology

A pre-post observational community study with a single-arm sample. Primary outcome is change in cognitive health knowledge. Secondary outcome is prevalence of AD8/SBT results in a Florida Latino community sample.

1
Pre-registration on OSF.io (before any data collection)
Full protocol pre-registered including instruments, cutoffs, demographic variables, analysis plan, and sample size justification. Timestamp establishes scientific priority.
2
Informed consent + HIPAA-informed privacy notice
All participants complete a digital consent form confirming voluntary participation, data anonymization, and right to withdraw. No names, SSNs, or identifiable information collected. Participant codes assigned by facilitator.
3
Demographics — 12 variables (D1–D12)
Age group, gender, Latino origin subgroup, education level, years of formal education, language at home, cohabitation, county/region, prior memory concern, prior cognitive diagnosis, chronic conditions (Lancet 2024 risk factors), and AD8 respondent type (self vs. informant).
Platform: Google Forms → Google Sheets · CSV export for SPSS/R analysis
4
Pre-test at Session 1 / Post-test at Session 4
10-item true/false cognitive health knowledge assessment. Primary outcome: change in score (paired t-test). Converts program from educational series to publishable training intervention evaluation.
5
AD8 online (Sessions 1–4) + SBT in-person (Session 4)
AD8 via Google Forms (Spanish self-report, cutoff ≥3 for US Latinos). SBT administered by trained facilitator following WashU guidelines, scores entered in password-protected facilitator form.
6
Statistical analysis
Descriptive statistics by demographic subgroup. Paired t-test for pre/post knowledge change. Education-stratified SBT analysis. Subgroup analysis by Latino origin, age group, and language. Cronbach's α reported for AD8.
Target: n ≥ 100 across ≥ 2 cohorts · Software: SPSS or R
