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. They...

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,...

Information Processing Approach

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is also...

Higher Mental Functions of Brain: Learning and Memory

Higher Mental Functions of Brain: Learning and Memory

Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or playing an...

Self-Schemas

Self-Schemas

In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

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:

Nutrition Science
Cognitive Neuroscience
Metabolic Health

Background:

Metabolic syndrome (MetS) and its components (hypertension, impaired glucose, dyslipidemia, obesity, inflammation) increase cognitive decline risk.
Dietary interventions preventing metabolic disorders may also prevent cognitive decline.
This study investigated a diet's impact on cognitive function in overweight, healthy individuals.

Purpose of the Study:

To assess the cognitive effects of a multifunctional diet designed to target MetS risk markers.
To evaluate cognitive performance in relation to cardiometabolic risk variables.

Main Methods:

A randomized, controlled crossover study with 44 healthy adults (50-73 years, BMI 25-33).
Participants consumed an active diet (AD) with anti-inflammatory foods and a control diet (CD) for 4 weeks each, separated by a washout period.
Cognitive tests were administered in fasting and postprandial states after each diet period.

Main Results:

The active diet (AD) significantly improved performance in auditory-verbal learning (recognition) and selective attention/working memory tests compared to the control diet (CD).
Cognitive performance showed inverse associations with cardiometabolic risk markers (cholesterol, glucose, blood pressure) and cardiovascular risk scores.
Cognitive performance was positively associated with apolipoprotein A1 levels.

Conclusions:

Dietary characteristics can modulate cognitive performance.
A link exists between cardiometabolic risk markers and cognitive function in healthy individuals.
Diet-based prevention of metabolic disturbances related to MetS is supported by these findings.
