WHY BRAIN HEALTH

Why Brain Health Matters

The brain supports memory, attention, movement, emotion, sleep, and the ability to navigate daily life.

Brain health is shaped over time by lifestyle choices, medical history, and environmental factors — many of which can be addressed before symptoms appear.

Yet early changes are often subtle and easy to dismiss.

NervLock exists to make evidence-based brain health information accessible, honest, and practical — without replacing the role of medical evaluation.

Research suggests that approximately 45% of dementia risk factors may be modifiable.

In some neurodegenerative conditions, pathological changes may begin years or decades before noticeable symptoms appear.

Brain health is meaningfully influenced by sleep quality, nutrition, physical activity, and stress management — all modifiable aspects of daily life.

SCIENCE & RESEARCH

Grounded in Evidence

NervLock prioritizes peer-reviewed medical literature and authoritative clinical guidelines when developing its content and products.

The Lancet Neurology
Article TitleThe characterisation of subjective cognitive decline
Study DesignInternational Expert Position Paper / Consensus
Key FindingsEstablished internationally accepted criteria for Subjective Cognitive Decline (SCD) and introduced the SCD-plus concept to identify individuals who may have a higher likelihood of future objective cognitive decline.
Clinical RelevanceProvides the scientific framework for evaluating patients who report memory decline despite normal cognitive testing. Supports distinguishing subjective cognitive decline from mild cognitive impairment and dementia while emphasizing that SCD alone is not a diagnosis of Alzheimer's disease.
World Health Organization (WHO)
Article TitleRisk reduction of cognitive decline and dementia: WHO Guidelines (Second Edition)
Study DesignInternational Clinical Guideline
Key FindingsProvides evidence-based recommendations for reducing the risk of cognitive decline and dementia through multidomain approaches including physical activity, vascular risk factor management, healthy diet, sleep, hearing care, and other lifestyle interventions.
Clinical RelevanceServes as one of the primary international references supporting NervLock's evidence-based approach to brain health education. Emphasizes risk reduction strategies while acknowledging that no intervention can guarantee dementia prevention for an individual.

Sleep Medicine Reviews
Article TitleImpact of One Night of Sleep Restriction on Sleepiness and Cognitive Function
Study DesignSystematic Review & Meta-analysis
Key FindingsOne night of sleep restriction significantly increases daytime sleepiness and impairs several aspects of cognitive performance, particularly sustained attention and alertness.
Clinical RelevanceProvides high-level evidence supporting the relationship between insufficient sleep and impaired attention, concentration, and memory. Forms part of the scientific foundation for NervLock's Brain Fog, Sleep, and Memory educational content.
