Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Triple Pill (active treatment) - telmisartan 20mg, amlodipine 2.5mg and indapamide 1.25mg: taken orally once daily for 4 weeks.

Medication adherence: At the end of study,
returned capsules will be counted and recorded by the study team. Additionally, participants will be provided with contact details of the responsible researcher so that they can make contact if for any reason they are unable to continue their study medication or have missed multiple doses and are unsure whether to continue.
Standard of care for participants is monotherapy with any blood pressure lowering medication and GP management.

Screening will involve the following:

Initial Online assessment: estimated 30 minutes
Telephone assessment: (Screening) estimated 40 minutes
First videoconference-(Consent and eligibility) estimated 40 minutes
Second videoconference: (Cognitive testing) estimated 90 minutes
At this point if the participant is eligible they will be randomised

Eligibility
Key inclusion criteria
Inclusion Criteria:
• Age 50 to 70 years.
• DSM-V diagnosis of Minor Neurocognitive Disorder:
o modest cognitive decline from a previous level of performance in at least one domain, based on the concerns of the individual, a knowledgeable informant or the clinician; and a decline in neurocognitive performance of >1 standard deviation below appropriate norms on formal testing or equivalent clinical evaluation.
o cognitive deficits are insufficient to interfere with daily activities, but that greater effort, compensatory strategies, or accommodation may be required to maintain independence.
o cognitive deficits do not occur exclusively in the context of a delirium.
o cognitive deficits are not primarily attributable to another mental disorder (for example major depressive disorder and schizophrenia).
• An additional enrichment factor indicating elevated risk for declining cognition, defined as one or more of self-reported: monotherapy treatment of hypertension, diabetes mellitus, elevated low-density lipoprotein cholesterol, obesity, current smoking, or first degree relative with dementia.
• Provision of online, verbal and electronic informed consent.

Other design features
The current global situation has challenged the undertaking of face-to-face visits for research studies and inevitably limits study recruitment opportunities. Videoconferencing technologies allow the delivery of medical, psychological and psychiatric services remotely. Recent studies have supported the validity and reliability of administering videoconference-based neuropsychological tests in rural and urban settings as an alternative to traditional face-to-face testing.
Diagnostic outcomes between videoconference and traditional face-to-face screenings for neurocognitive disorders are similar, in participants aged 65 to 75 years, and in studies that utilize high speed network connection

Type of endpoint/s
Safety/efficacy
Statistical methods / analysis
The ATHENA study is a pilot feasibility study that has the purpose of (1) ensuring that the trial is feasible and (2) to gather information on cognitive measures to inform a sample size calculation of a further large-scale study.

Summary
Brief summary
The Action To promote brain HEalth iN Adults (ATHENA) pilot trial uses an RCT design and involves treatment with a low-dose triple combination pill of BP lowering agents or placebos. ATHENA will evaluate the feasibility, applicability, tolerability, safety and adherence of a risk reduction approach in a high-risk target population, evaluating a BP lowering intervention. In the current study, we will also test the feasibility of recruitment and assessment of a population with higher than average risk of dementia (i.e. DSM-V diagnosis of Minor Neurocognitive Disorder) remotely. The screening will be made through online assessments with subsequent telephone calls to assess eligibility and videoconference neuropsychological assessments.
