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.

Area of Science:

Neuroscience
Regenerative Medicine
Anesthesiology

Background:

Postoperative cognitive dysfunction (POCD) is a frequent central nervous system complication in elderly patients following general anesthesia.
POCD significantly impairs patient recovery, quality of life, and increases risks of psychiatric disorders or mortality.
Cerebral ischemia/reperfusion injury leading to neuronal damage and inflammation is the primary mechanism behind POCD.

Purpose of the Study:

To review existing research on extracellular vesicles (EVs) for treating POCD.
To explore the potential of EVs in nerve repair and mitigating neuroinflammation.
To discuss EVs as novel cell-free therapeutic strategies for POCD.

Main Methods:

Literature review of studies investigating EVs in the context of POCD.
Analysis of EV properties related to regenerative and anti-inflammatory effects.
Discussion of therapeutic potential and future directions for EV-based treatments.

Main Results:

Extracellular vesicles possess pro-regenerative and pro-repair capabilities.
EVs demonstrate an ability to modulate immune responses and reduce neuroinflammation.
EVs are proposed as effective nanopathways for modulating POCD.

Conclusions:

Repairing neuronal damage and reducing neuroinflammation are key to intervening in POCD.
Extracellular vesicles offer a promising therapeutic avenue for POCD.
EVs represent a potential novel cell-free therapeutic pathway for managing POCD.
