Area of Science:

  • Neuroscience
  • Gerontology
  • Pharmacology

Background:

  • Aging and senile dementias are associated with complex deficiencies in the brain's cholinergic system.
  • Understanding these changes in cholinergic neurons and receptors is crucial for developing therapeutic strategies.

Purpose of the Study:

  • To present the complex picture of age-associated brain cholinergic deficiency.
  • To discuss the possibilities of correcting these deficiencies.
  • To review current and potential therapeutic interventions.

Main Methods:

  • Review of scientific literature on aging, dementia, and the cholinergic system.
  • Description and discussion of changes in cholinergic neurons, receptors, and acetylcholine synthesis/release.
  • Listing and detailed discussion of drugs administered to humans for cholinergic deficiency.

Main Results:

  • Detailed description of age- and dementia-related alterations in the cholinergic system.
  • Identification of key drug classes, including cholinesterase inhibitors, nerve growth factor, and phosphatidylserine, as potential treatments.
  • Discussion of the efficacy and mechanisms of these interventions.

Conclusions:

  • Age-associated cholinergic deficiency is a significant factor in cognitive decline.
  • Pharmacological interventions targeting the cholinergic system show promise for correcting these deficiencies.
  • Further research into these treatments is warranted for managing age-related cognitive impairments.
