Navigational object-location memory assessment in real and virtual environments: A systematic review.

Navigational object-location memory (OLM) is a form of spatial memory involving actual or virtual body displacement for repositioning previously encoded objects within an environment. Despite its potential for higher ecological validity measures, navigational OLM has been less frequently assessed than static OLM. The present systematic review aims to characterize the methodology and devices used for OLM assessment in navigational real and virtual environments and synthesize recent literature to offer a comprehensive overview of OLM performance in both pathological and non-pathological adult samples.

An immersive virtual reality-based object-location memory task reveals spatial long-term memory alterations in Long-COVID.

Object-location memory (OLM) is a type of declarative memory for spatial information and consists of the individual's ability to establish accurate associations between objects and their spatial locations. Long-COVID describes the long-term effects of the COVID-19 disease. Long-COVID patients show medial temporal lobe dysfunction and neuropsychological alterations affecting memory.

Hippocampal alterations after SARS-CoV-2 infection: A systematic review.

SARS-CoV-2 infection produces a wide range of symptoms. Some of the structural changes caused by the virus in the nervous system are found in the medial temporal lobe, and several neuropsychological sequelae of COVID-19 are related to the function of the hippocampus. The main objective of the systematic review is to update and further analyze the existing evidence of hippocampal and related cortices' structural and functional alterations due to SARS-CoV-2 infection.

Anosmia in COVID-19 could be associated with long-term deficits in the consolidation of procedural and verbal declarative memories.

Background And Purpose: Long-COVID describes the long-term effects of the coronavirus disease 2019 (COVID-19). In long-COVID patients, neuropsychological alterations are frequently reported symptoms. Research points to medial temporal lobe dysfunction and its association with anosmia in long-COVID patients.

Memory alterations after COVID-19 infection: a systematic review.

SARS-CoV-2 infection has a wide range of both acute and long-term symptoms. Memory alterations have been frequently reported in studies that explore cognition. The main objective of the systematic review is to update and further analyze the existing evidence of objective memory impairments in long-COVID-19 considering sample and study design characteristics, as well as to explore associations between memory performance and their epidemiological, clinical, and pathological features.

Psychomotor development in very and extremely low-birth-weight preterm children: Could it be predicted by early motor milestones and perinatal complications?

Preterm-born children are at risk of slower psychomotor development. This risk may be associated with low birth weight and other perinatal factors and morbidities. We aimed to assess psychomotor development in school-aged preterm children, and to determine whether some early motor and perinatal variables could be related to and/or predict the later motor achievements.

Functional neuroanatomy of allocentric remote spatial memory in rodents.

Successful spatial cognition involves learning, consolidation, storage, and later retrieval of a spatial memory trace. The functional contributions of specific brain areas and their interactions during retrieval of past spatial events are unclear. This systematic review collects studies about allocentric remote spatial retrieval assessed at least two weeks post-acquisition in rodents.

Functional near-infrared spectroscopy in the neuropsychological assessment of spatial memory: A systematic review.

Functional near-infrared spectroscopy (fNIRS) is a non-invasive optical imaging technique that employs near-infrared light to measure cortical brain oxygenation. The use of fNIRS has increased exponentially in recent years. Spatial memory is defined as the ability to learn and use spatial information.

Evaluation of Visuospatial Short-term and Working Memory from the First to Second Year of Life: A Novel Task.

The prototypical tasks for assessing visuospatial memory in infancy are based on the search for a hidden object in two locations. Fewer studies include more locations, delayed responses nor changes in the object's position. Our aim was to assess the visuospatial short-term and working memory in 12, 15, 18 and 22-month-old children (N = 65).

Development of visuospatial memory in preterm infants: A new paradigm to assess short-term and working memory.

Preterm infants have a higher risk of showing visuospatial memory impairment, the function that allows to encode and remember visual and spatial information. It has been studied in late childhood in preterm children. Studies on visuospatial memory throughout the first 2 years of life are still scarce.

The association between perinatal and neonatal variables and neuropsychological development in very and extremely low-birth-weight preterm children at the beginning of primary school.

Preterm children with very low birth weight (<1,500 g) and extremely low birth weight (<1,000 g) have an increased risk of experiencing neuropsychological delays. The purpose of this study is to characterize the neuropsychological profile of very and extremely low birth weight preterm children and discover what maternal conditions, diseases, procedures, and alterations in preterm newborns could be related to their later neuropsychological development. Eighty-nine preterm children (aged from 5 to 7 years) were assessed on their intelligence quotient (IQ), executive function, memory, and visuospatial memory in a single session, using the RIST and NEPSY-II test.

Development of egocentric and allocentric spatial orientation abilities in children born preterm with very low birth weight.

Background: Very low birth weight preterm infants show neuropsychological alterations in functions such as memory or visuospatial skills, although certain related functions, such as spatial orientation, have not been studied.

Objectives: To compare children born preterm and at term between the ages of 5 and 7 years on egocentric and allocentric spatial orientation, and relate their performance to visuospatial skills, behavior, memory in daily environments, and perinatal risk factors.

Study Design: Observational cross-sectional study.
