Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

193
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.

Cognitive Development During Adulthood

218
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,...

Area of Science:

  • Neuroscience
  • Nutrition Science
  • Gerontology

Background:

  • Aging and increased adiposity can affect brain creatine levels.
  • Brain creatine is crucial for maintaining cognitive functions.
  • Cognitive decline is a concern in the elderly population.

Purpose of the Study:

  • To investigate the relationship between dietary creatine intake and cognitive performance.
  • To assess if creatine consumption impacts cognition in elderly women with overweight.
  • To explore potential nutritional strategies for supporting cognitive health in older adults.

Main Methods:

  • Twenty-seven overweight women over 60 years old participated.
  • Cognitive performance was evaluated using the Eriksen Flanker Task (EFT).
  • Dietary creatine intake was estimated over 5 days using nutritional recalls.

Main Results:

  • Significant differences in EFT performance were observed between low and high creatine intake groups.
  • Reaction time to incongruent stimuli showed a negative correlation with creatine intake (r = -0.383, p = 0.004).
  • The percentage of correct answers strongly correlated with daily creatine intake (r = 0.743, p < 0.001).

Conclusions:

  • Dietary creatine intake appears to influence cognitive ability in elderly women with overweight.
  • Findings suggest creatine is an important dietary factor for cognition in older adults.
  • This highlights the potential role of creatine supplementation or dietary adjustments for cognitive support.
