Cognitive Development During Adulthood01:30

Cognitive Development During Adulthood

1.1K
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,...

Pharmacodynamics in Geriatric Patients: Effects of Age

309
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

4.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Mitochondria01:37

Mitochondria

21.2K
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

804
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.

Long-term Potentiation01:25

Long-term Potentiation

3.8K
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

LTP can occur when...

Area of Science:

  • Neuroscience
  • Aging Research
  • Molecular Biology

Background:

  • Cognitive deficits are common in aging humans and animals, with limited therapeutic options due to poorly understood mechanisms.
  • Research links cognitive performance to the cellular excitability of CA1 hippocampal neurons, highlighting the need to identify age-related molecular regulators.
  • The transcription factor cAMP response element binding-protein (CREB) is implicated in both cognitive function and neuronal excitability.

Purpose of the Study:

  • To investigate the role of CREB in age-related cognitive deficits and neuronal excitability.
  • To explore CREB as a potential therapeutic target for mitigating cognitive decline associated with aging.

Main Methods:

  • Review of existing literature on CREB, cognition, and aging.
  • Analysis of studies linking CREB activity to cognitive performance and neuronal excitability in young and aged subjects.
  • Hypothesizing CREB's role in age-related dysfunction.

Main Results:

  • CREB activity modulation impacts cognitive performance and neuronal excitability in young animals.
  • Evidence suggests CREB signaling may be impaired with aging.
  • CREB dysfunction potentially contributes to age-related cognitive deficits.

Conclusions:

  • CREB signaling is a critical regulator of cognition and neuronal excitability.
  • Dysfunctional CREB signaling may underlie age-related cognitive impairments.
  • CREB presents a promising therapeutic target for treating age-related cognitive deficits.
