Cognitive Development During Adulthood01:30

Cognitive Development During Adulthood

22
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,...

Dementia01:30

Dementia

64
Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual....

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

85
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.

Alzheimer's Disease: Overview01:26

Alzheimer's Disease: Overview

315
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Negative and Cognitive Symptoms of Schizophrenia01:30

Negative and Cognitive Symptoms of Schizophrenia

29
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Cognitivism01:17

Cognitivism

1.3K
Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

Area of Science:

  • Gerontology
  • Neurology
  • Psychiatry

Background:

  • Cognitive decline and dementia are significant concerns in aging populations.
  • Neuropsychiatric symptoms (NPS) and mild behavioral impairment (MBI) are increasingly recognized as potential early indicators of neurological changes.

Purpose of the Study:

  • To investigate the association between later-life NPS and modified mild behavioral impairment (MBI) diagnoses with subsequent cognitive decline.
  • To determine if these behavioral changes can predict the risk of developing dementia.

Main Methods:

  • A prospective cohort study followed 823 non-demented individuals aged 70-90 years for six years.
  • Cognition was assessed biennially using neuropsychological testing.
  • NPS and MBI (MBI-Lite) were evaluated using validated scales and algorithms, controlling for genetic and cardiovascular risk factors.

Main Results:

  • Higher NPS scores correlated with worse global cognition and increased dementia risk over six years.
  • Clinically significant NPS in cognitively normal individuals predicted worse cognitive scores.
  • A diagnosis of MBI-Lite was also associated with poorer cognitive outcomes.

Conclusions:

  • Specific NPS measures in cognitively normal older adults may signal future cognitive decline.
  • These behavioral markers could aid in early diagnosis and advance dementia research.
