Cognitive Development During Adulthood

472
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,...

Negative and Cognitive Symptoms of Schizophrenia

191
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,...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

298
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: Overview

1.0K
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...

Summary
This summary is machine-generated.

Sluggish cognitive tempo (SCT) is linked to significant neuropsychological deficits in children, including slower processing and attention issues. These SCT-related impairments persist even when accounting for attention-deficit/hyperactivity disorder (ADHD) symptoms.

Area of Science:

  • Neuroscience
  • Child Psychology
  • Cognitive Science

Background:

  • Sluggish cognitive tempo (SCT) is associated with social, emotional, and academic impairments.
  • Limited research exists on the link between SCT and neuropsychological functioning.

Purpose of the Study:

  • To investigate the associations between SCT symptoms and various neuropsychological functions in children and adolescents.
  • To determine if SCT-related deficits are distinct from attention-deficit/hyperactivity disorder (ADHD) symptoms.

Main Methods:

  • Neuropsychological assessments were administered to a subsample of 928 children with SCT or ADHD symptoms and 652 controls (ages 5.9-15.4).
  • Multiple regression analyses were used to examine the associations between SCT symptoms and cognitive measures.

Main Results:

  • SCT symptoms were independently associated with deficits in processing speed, working memory, inhibition, vigilance, and reaction time.
  • These cognitive weaknesses remained significant after controlling for ADHD-inattention, anxiety, and depression symptoms.

Conclusions:

  • SCT is characterized by widespread neuropsychological deficits.
  • Findings support SCT as a distinct symptom profile separate from ADHD-inattention.
