Primary Healthcare Services

1.9K
Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.

Levels of Health Promotion and Illness Prevention

14.1K
Health promotion allows a person to control the determinants of health, resulting in an improved health status. It enhances the quality of life and reduces premature deaths. Health promotion and illness prevention programs help people make beneficial choices to reduce the risk of disease and disabilities. There are three health promotion and illness prevention levels: primary, secondary, and tertiary prevention.
In primary prevention, actions taken before disease onset prevent the disease from...

Preventive Healthcare Services

1.8K
Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

439
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Methods Of Healthcare Delivery System

3.9K
At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...

Summary
This summary is machine-generated.

The Brain Health Index (BHI) offers a unified score for cognitive health, integrating vulnerability, resilience, and performance measures. Higher BHI scores correlate with a reduced likelihood of cognitive impairment.

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Public Health

Background:

  • The Brain Health Index (BHI) is a novel composite measure designed to assess overall cognitive health.
  • It integrates the Vulnerability Index (VI), Resilience Index (RI), and Number-Symbol Coding Task (NSCT).
  • The BHI provides a single, validated score for tracking cognitive health and risk factors.

Purpose of the Study:

  • To develop and validate a comprehensive metric for cognitive health assessment.
  • To provide clinicians and researchers with a unified score reflecting brain and body health.
  • To enable the tracking of aggregate risk factors for cognitive impairment over time.

Main Methods:

  • Data from 265 participants (184 cognitively normal, 81 with mild cognitive impairment) were analyzed.
  • Component weights were determined using factor analysis and SHAP values from random forest modeling.
  • Validation involved correlational analyses with neuroimaging, biomarkers, gait, and cognitive tests.

Main Results:

  • The BHI showed significant correlations with total cortical volume (r=-.279), phenotypic age (r=-.442), MoCA scores (r=.500), and gait velocity (r=.480).
  • Higher BHI scores were significantly associated with a lower likelihood of cognitive impairment (r²=-.125).
  • These findings support the BHI's validity as a measure of cognitive health.

Conclusions:

  • The Brain Health Index (BHI) successfully integrates vulnerability, resilience, and performance into a unified cognitive health metric.
  • The BHI correlates significantly with established biomarkers and cognitive function measures.
  • A digital platform has been deployed for further validation of the BHI in a larger population.
