Summary
Cognitive impairments like memory and concentration issues are common after COVID-19, impacting work and life quality. Routine cognitive screening is recommended for long-COVID patients using tools like the SCIP test.
Area of Science:
- Neurology
- Infectious Diseases
- Psychiatry
Background:
- Cognitive sequelae, including memory and concentration deficits, are frequently reported following COVID-19 infection.
- These impairments affect a significant portion of both hospitalized (40-65%) and non-hospitalized (27-50%) individuals.
- Cognitive difficulties post-COVID-19 are linked to diminished work capacity and overall quality of life.
Purpose of the Study:
- To review the prevalence and impact of cognitive impairments after COVID-19.
- To advocate for systematic cognitive screening in long-COVID care pathways.
- To identify suitable objective cognitive assessment tools for clinical use.
Main Methods:
- Literature review of studies reporting cognitive outcomes in COVID-19 survivors.
- Analysis of the association between cognitive deficits and functional outcomes.
- Evaluation of existing cognitive screening instruments for feasibility and sensitivity.
Main Results:
- High prevalence of cognitive impairments observed across different COVID-19 patient groups.
- Documented negative correlation between cognitive function and work performance/quality of life.
- Identification of specific cognitive domains affected, such as memory and attention.
Conclusions:
- Systematic cognitive screening should be integrated into long-COVID clinics.
- Brief, objective cognitive screeners like the Screen for Cognitive Impairment in Psychiatry (SCIP) and Trail Making Test B are recommended.
- Screening tools should demonstrate sensitivity to cognitive impairment, particularly in younger populations affected by long COVID.

01:30Cognitive Development During Adulthood
343
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,...

01:30Negative and Cognitive Symptoms of Schizophrenia
138
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,...

01:03Long-term Depression
2.7K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

01:27Language and Cognition
478
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

01:14Role of Cerebellum and Prefrontal Cortex in Memory
623
The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the...
