Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

151
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.

Brain Imaging

257
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Summary

Traumatic brain injury (TBI) recovery is hindered by brain edema, inflammation, and cell death. Neurosteroids offer a promising therapeutic avenue for TBI treatment due to their pleiotropic effects.

Area of Science:

  • Neuroscience
  • Pharmacology
  • Biochemistry

Background:

  • Traumatic brain injury (TBI) induces widespread pathological changes affecting multiple physiological systems.
  • Impediments to functional recovery include brain edema, inflammation, cell death, and neurovascular disruption.
  • Current drug development aims to address these deficits, but a multifaceted approach is likely necessary.

Purpose of the Study:

  • To review the role of neurosteroids in TBI.
  • To explore the potential of neurosteroid signaling systems for TBI drug development.
  • To propose future research directions for neurosteroid-based TBI therapies.

Main Methods:

  • This study is a narrative review.
  • It examines existing literature on neurosteroids and their signaling pathways.
  • It synthesizes information to propose therapeutic strategies for TBI.

Main Results:

  • The neurosteroid system is a complex network with potential for pleiotropic drug development.
  • Targeting neurosteroids could offer a single-drug or combination therapy approach for TBI.
  • Neurosteroids show promise in mitigating multiple TBI-induced pathologies.

Conclusions:

  • The neurosteroid system presents a viable target for developing novel TBI therapeutics.
  • Further research into neurosteroid signaling is crucial for advancing TBI treatment.
  • Pleiotropic drugs targeting neurosteroids may significantly improve outcomes for TBI patients.
