Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists01:30

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...
Long-term Potentiation01:25

Long-term Potentiation

Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

Dementia l: Introduction01:22

Dementia l: Introduction

Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...

Area of Science:

  • Neuroendocrinology
  • Cognitive Science
  • Population Health

Background:

  • Leptin's known positive effects on cognition lack investigation in diverse, population-based samples.
  • Previous studies have not stratified leptin's cognitive impact by race or gender.

Purpose of the Study:

  • To investigate the association between leptin levels and cognitive performance in a population-based sample.
  • To examine if leptin's effect on cognition differs when stratified by race and gender.

Main Methods:

  • Measured leptin and fat mass in 2,731 diverse subjects (50% African American).
  • Assessed cognitive function using the Montreal Cognitive Assessment (MoCA) eight years later.
  • Analyzed demographic factors and baseline leptin levels (deficiency or excess) as predictors of cognitive performance.

Main Results:

  • A trend suggested lower leptin levels correlate with higher cognitive scores.
  • Excessive leptin was linked to lower MoCA scores and impaired delayed recall in Black men.
  • White men showed an inverse relationship between excessive leptin and cognitive performance.

Conclusions:

  • Excess leptin has differential effects on cognitive function, specifically delayed recall, in Black versus White men.
  • Race and gender are critical factors in understanding leptin's influence on cognition.
