Tutorials in population neuroimaging: Using epidemiology in neuroimaging research.

Area of Science:

• Public Health
• Neuroimaging Research
• Epidemiology

Background:

• Epidemiology is fundamental to public health research and practice.
• It provides essential frameworks for organizing data and critical thinking in research.
• Epidemiology addresses population heterogeneity and potential threats to study validity.

Purpose of the Study:

• To highlight the critical role and applications of epidemiology in advancing neuroimaging research.
• To emphasize how epidemiological principles guide the research process from design to inference.
• To showcase epidemiology as a tool for discovering novel risk factors, disease states, and subpopulations.

Main Methods:

• The abstract discusses the foundational principles of epidemiology.
• It outlines the utility of epidemiological frameworks in research design and critical thinking.
• It emphasizes the importance of accounting for population heterogeneity and validity threats.

Main Results:

• Epidemiology provides a structured approach to neuroimaging research.
• It aids in identifying potential biases and improving the validity of studies.
• Epidemiological insights facilitate the discovery of new etiological factors and patient subgroups.

Conclusions:

• A strong understanding of epidemiology uniquely positions neuroimaging researchers for valid clinical and etiological studies.
• Epidemiology is indispensable for rigorous and impactful neuroimaging research.
• Applying epidemiological principles enhances the depth and breadth of neuroimaging investigations.
