Regression Toward the Mean

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

Introduction to Cognitive Psychology

Introduction to Cognitive Psychology

Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing.
This field emerged in the mid-20th century, following a period dominated by behaviorism, which...

Area of Science:

Health Informatics
Cognitive Neuroscience
Machine Learning

Background:

Machine learning (ML) applications in health research are expanding.
Predicting cognitive outcomes with health indicators using ML is understudied.

Purpose of the Study:

Utilize ML models to predict cognitive performance.
Identify key health and behavioral contributors to cognitive function.
Inform personalized interventions for cognitive health.

Main Methods:

Developed ML models using data from 374 adults (aged 19-82).
Included demographics, anthropometrics, dietary indices, physical activity, and blood pressure as features.
Employed various regression models with hyperparameter tuning and cross-validation.

Main Results:

Random forest regressor achieved the best performance.
Age, diastolic blood pressure, BMI, and systolic blood pressure were significant predictors.
Healthy Eating Index showed a subtler effect, while ethnicity and sex had minimal impact.

Conclusions:

Age, blood pressure, and BMI strongly correlate with cognitive performance.
Diet quality has a less pronounced but notable association.
ML models show promise for personalized cognitive health interventions and prevention strategies.
