Negative and Cognitive Symptoms of Schizophrenia01:30

Negative and Cognitive Symptoms of Schizophrenia

635
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,...

Pathophysiology of Cardiac Performance01:29

Pathophysiology of Cardiac Performance

1.6K
Typical heart performance is influenced by heart rate, rhythm, myocardial contraction, and metabolism or blood flow. The cardiac muscle exhibits distinct electrophysiological features, including pacemaker activity and calcium channel control, which play a vital role in the heart's response to various drugs. The autonomic nervous system, comprising the sympathetic and parasympathetic branches, regulates heart rate. Sympathetic activation increases heart rate, while parasympathetic activation...

Exercise and Muscle Performance01:27

Exercise and Muscle Performance

2.5K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Sources of Self-Esteem II: Performance Feedback

195
Self-esteem is intricately tied to our perception of competence and our ability to exert control over our lives. One of the primary sources of this perception is performance feedback — the ongoing evaluation of our actions in terms of success and failure. According to Franks and Marolla (1976), people derive self-worth from experiencing themselves as causal agents, capable of achieving goals and overcoming obstacles. This process nurtures a critical component of self-esteem:...

High-Performance Liquid Chromatography: Introduction01:11

High-Performance Liquid Chromatography: Introduction

3.6K
High-performance liquid chromatography(HPLC), formerly referred to as High-pressure liquid chromatography, is a powerful technique used to separate, identify, and quantify components in complex mixtures. The term "high pressure" refers to using high pressure to push the liquid mobile phase through the tightly packed columns.
In HPLC, two phases play a critical role in the separation process:

High-Performance Liquid Chromatography: Instrumentation00:57

High-Performance Liquid Chromatography: Instrumentation

3.1K
High-performance liquid chromatography, or HPLC, is an analytical technique that separates liquid samples under high pressures. An HPLC instrument consists of glass bottles for storing solvents called mobile phase reservoirs. HPLC-grade solvents are used to maintain high purity, and the dissolved gases are removed using a degasser, such as a vacuum pumping system or sparging with helium. The solvents are then pumped into the analytical column using a screw-driven syringe or reciprocating pumps.

Summary

The 5-Choice Continuous Performance Task (5C-CPT) effectively measures sustained attention in schizophrenia patients, correlating well with established measures. This validated task can aid in developing new cognitive treatments for schizophrenia.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Cognitive Psychology

Background:

  • Attentional dysfunction is a key deficit in schizophrenia (SZ), impacting daily functioning.
  • Current sustained attention measures (CPTs) often lack cross-species validity and engage other cognitive functions.
  • The 5-Choice Continuous Performance Task (5C-CPT) was developed for humans, adapted from rodent models, to isolate attentional demands.

Purpose of the Study:

  • To validate the 5C-CPT against a gold-standard measure of vigilance in schizophrenia patients.
  • To assess the relationship between 5C-CPT performance and broader cognitive abilities in SZ.
  • To determine the translational utility of the 5C-CPT for cognitive research in neuropsychiatric disorders.

Main Methods:

  • Examined the correlation between the 5C-CPT and the CPT-Identical Pairs (CPT-IP) from the MATRICS Consensus Cognitive Battery (MCCB) in 35 schizophrenia patients.
  • Assessed relationships between 5C-CPT scores and global/subdomain cognitive performance within the MCCB.
  • Utilized regression analysis to determine shared variance in cognitive performance.

Main Results:

  • A strong positive correlation (r=0.60) was found between 5C-CPT and CPT-IP measures of sustained attention (d-prime).
  • Together, 5C-CPT and CPT-IP explained 54% of the variance in total MCCB scores.
  • A significant 27.6% of overall cognitive variance was shared between the 5C-CPT and CPT-IP.

Conclusions:

  • The 5C-CPT and CPT-IP capture a common attentional construct relevant to schizophrenia.
  • The 5C-CPT demonstrates significant overlap with general cognitive performance in SZ.
  • The 5C-CPT's cross-species validity offers a promising tool for developing pro-cognitive therapeutics for SZ and related disorders.
