Teeth

Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Cognitive Development During Adulthood

Cognitive Development During Adulthood

Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Negative and Cognitive Symptoms of Schizophrenia

Negative and Cognitive Symptoms of Schizophrenia

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Language and Cognition

Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Area of Science:

Gerontology
Epidemiology
Neuroscience

Background:

Periodontitis is a prevalent oral infection affecting older adults.
Cognitive decline is a significant concern in aging populations.
Potential links between oral health and cognitive function require further investigation.

Purpose of the Study:

To investigate the epidemiological association between periodontitis and cognitive performance in a U.S. older adult population.
To determine if periodontitis severity correlates with cognitive function deficits.

Main Methods:

Utilized data from 2086 older adults (≥60 years) from the NHANES 2011-2014 database.
Classified periodontitis severity (mild, moderate, severe) using AAP/CDC criteria.
Assessed cognitive function via CERAD, AFT, DSST, and global cognition scores, defining low performance as the lowest quartile.

Main Results:

Moderate and severe periodontitis showed significant associations with low Digit Symbol Substitution Test (DSST) performance.
Increased clinical attachment loss (CAL) correlated with lower performance in Animal Fluency Test (AFT), DSST, and global cognition.

Conclusions:

An independent association exists between periodontitis and reduced cognitive performance in older adults.
Periodontitis may represent a modifiable risk factor for cognitive impairment in aging individuals.
