Dose-Response Relationship: Overview

Dose-Response Relationship: Overview

Agonists can bind with and activate receptors, resulting in the formation of drug-receptor complexes. Once formed, these complexes catalyze many biochemical processes at the cellular level and subsequently induce a pharmacologic response. The degree of response is directly proportional to the fraction of activated receptors, which in turn, depends on the concentration of the drug at the receptor site as well as the sensitivity of the receptor. An increase in the administered dose contributes to...

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.

Cognitive Development During Adulthood

Cognitive Development During Adulthood

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,...

Dose-Response Relationship: Potency and Efficacy

Dose-Response Relationship: Potency and Efficacy

The potency of a drug is the measure of its ability to produce a biological response and can be compared by looking at the half-maximum effective concentration or EC50 values of different drugs. A lower EC50 value indicates higher potency of the drug. In the dose–response curve of two antihypertensive drugs, candesartan and irbesartan, a significant difference is observed in their EC50 values. A lower EC50 value for candesartan indicates that it is more potent than irbesartan, as it...

Summary

Computerized cognitive training (CCT) shows a dose-dependent effect on cognitive improvement. Optimal CCT doses for cognitive enhancement vary by age, with younger adults needing less training than older adults.

Background:

Computerized cognitive training (CCT) is a recognized digital intervention for cognitive impairment.
The dose-response relationship of CCT remains understudied, limiting optimal usage guidelines.

Purpose of the Study:

To investigate the association between CCT dose and cognitive improvement.
To determine the optimal CCT dose for enhancing cognitive function.

Main Methods:

Retrospective cohort study analyzing 8,709 participants from 2017-2022.
Participants had subjective cognitive decline, mild cognitive impairment, or mild dementia.
Cognitive improvement was measured weekly using the Cognitive Index.

Main Results:

Significant Cognitive Index increases were observed across various CCT dose groups.
Optimal CCT dose for individuals under 60: 25 to <30 minutes/day, 6 days/week.
Optimal CCT dose for individuals 60+: 50 to <55 minutes/day, 6 days/week.

Conclusions:

CCT exhibits a dose-dependent effect on cognitive improvement.
Age-specific optimal dosing strategies for CCT are recommended for maximizing cognitive benefits.
