Article Synopsis
  • Visual mental imagery (VMI) is the brain's ability to create images without actual sensory input, and it shows changes in Alzheimer's disease (AD) but hasn't been studied in the earlier stage called mild cognitive impairment (MCI).
  • The study examined VMI in 14 mild AD patients, 19 with amnestic MCI, and 23 healthy controls using specific tests to measure different VMI processes.
  • Results indicated that AD patients struggled significantly with image creation and manipulation, while those with aMCI had issues mostly with creating mental images, suggesting VMI deficits appear early in the progression of Alzheimer's.

An interesting interpretation of embodiment highlights the critical role of mental body representations (BR), including motor, somatosensory, and interoceptive formats, for social cognition. However, the nature of this relationship is still debated at the empirical level, with various studies arriving at different conclusions. Here, we present a systematic review and meta-analysis aimed to summarize data from 3466 participants in 21 studies to provide a more comprehensive understanding of the relationship between inner and outer BR and social cognition.

Background: The mental representation of the body (or body representation, BR) derives from the processing of multiple sensory and motor inputs and plays a crucial role in guiding our actions and in how we perceive our body. Fundamental inputs for BR construction come also from the interoceptive systems which refer to the whole bidirectional processes between the brain and the body. People with Multiple sclerosis (MS) show an abnormal multisensory integration which may compromise BR and interoception integrity.

Background And Objective: Neonatal screening and early treatment have changed the natural history of PKU, preventing severe neurological and intellectual disability. Nevertheless, the outcome of the disease in early-treated adult patients (ETPKU) is less than optimal, the predictive value of metabolic biomarkers is feeble, and the recommended levels of blood phenylalanine (Phe) for adulthood are controversial. A crucial question whose answer will improve our understanding and treatment of PKU is whether cognitive outcomes can be modulated by levels of Phe even in early-treated adults.

Article Synopsis
  • - Recent research has shown that changes in sensitivity to internal body sensations throughout life can influence how individuals mentally represent their bodies, specifically in action-oriented vs. nonaction-oriented contexts.
  • - In a study involving sixty-five stroke patients, it was discovered that interoceptive sensibility (awareness of internal sensations) negatively affected the performance on nonaction-oriented body representation tasks; higher sensitivity led to poorer task performance.
  • - The findings suggest that specific brain pathways, particularly involving the frontal areas and certain tracts like the corticospinal and fronto-insular tracts, are crucial for understanding this relationship between body representation and interoceptive sensibility.

Article Synopsis
  • Early studies focused on interoception as awareness of internal body sensations, but recent theories broadened it to include overall body status and somatosensory feelings.
  • The study involved structural MRI scans of healthy individuals and analyses of brain connectivity in patients with unilateral brain damage to explore neural connections linked to interoceptive sensibility.
  • Findings indicate a clear distinction between visceral (F1) and somatosensory (F2) interoceptive sensations, with F1 related to brain areas like the anterior cingulate cortex and F2 associated with multiple white matter tracts in the right hemisphere.

Mental representations with bodily contents or in various bodily formats have been suggested to play a pivotal role in social cognition, including empathy. However, there is a lack of systematic studies investigating, in the same sample of participants and using an individual differences approach, whether and to what extent the sensorimotor, perceptual, and interoceptive representations of the body could fulfill an explanatory role in the empathic abilities.To address this goal, we carried out two studies in which healthy adults were given measures of interoceptive sensibility (IS), action (aBR), and nonaction-oriented body representations (NaBR), and affective, cognitive, and motor empathy.

Background: Cognitive impairment (CI) is common in Multiple Sclerosis (MS), and its prevalence rate ranges between 22% and 70%. Because CI significantly impacts vocational status, caregiver burden, and quality of life, an accurate neuropsychological assessment is required. Three widely used and validated batteries for MS-associated CI are the Brief Repeatable Neuropsychological Battery (BRN-B), the Minimal Assessment of Cognitive Function (MACFIMS), and the Brief International Cognitive Assessment (BICAMS).

A specific interpretation of embodiment assigns a central role to the body representations (BR) in cognition. In the social cognition domain, BR could be pivotal in representing others' actions and states. However, empirical evidence on the relationship between different BR and social cognition, in terms of Theory of Mind (ToM), in the same sample of participants is missing.

  • Developmental Topographical Disorientation (DTD) is a condition that makes it difficult for people to find their way in familiar settings, even without brain damage or cognitive impairment.
  • A study involving 54 young adults with DTD compared them to 54 healthy participants, examining demographics, navigational skills, and difficulties like left-right confusion and recognizing landmarks.
  • This research aims to deepen the understanding of DTD, highlighting its significance as the number of cases seems to be increasing, and it was first recognized only 13 years ago.

Background And Purpose: Although the latest breakthroughs in radiotherapy (RT) techniques have led to a decrease in adverse event rates, these techniques are still associated with substantial toxicity, including xerostomia. Imaging biomarkers could be useful to predict the toxicity risk related to each individual patient. Our preliminary work aims to develop a radiomic-based support tool exploiting pre-treatment CT images to predict late xerostomia risk in 3 months after RT in patients with oropharyngeal cancer (OPC).

In the last decade, several cases affected by Developmental Topographical Disorientation (DTD) have been described. DTD consists of a neurodevelopmental disorder affecting the ability to orient in the environment despite well-preserved cognitive functions, and in the absence of a brain lesion or other neurological or psychiatric conditions. Described cases showed different impairments in navigational skills ranging from topographic memory deficits to landmark agnosia.

Studies that have shown a distinction between object and spatial imagery suggest more than one type of aphantasia and hyperphantasia, yet this has not been systematically investigated in studies on imagery ability extremes. Also, if the involuntary imagery is preserved in aphantasia and how this condition affects other skills is not fully clear. We collected data on spatial and object imagery, retrospective, and prospective memory, face recognition, and sense of direction (SOD), suggesting a distinction between two subtypes of aphantasia/hyperphantasia.

Article Synopsis
  • Interoceptive information is essential for forming cognitive body representations (BR) that influence how we perceive and interact with our bodies, categorized into action-oriented (like body schema) and non-action-oriented (like a visuo-spatial body map).
  • A study with 239 healthy participants of various age groups found that children and older adults performed worse than young and middle-aged adults on tasks related to both types of BR.
  • The research indicated an inverted U-shaped trend in the development of BR, suggesting that higher interoceptive sensibility in both children and older adults might negatively impact their ability to mentally represent their body states.

Interoceptive information plays a pivotal role in building body representations (BR), but the association between interoception and the different types of BR in healthy individuals has never been systematically investigated. Thus, this study aimed to explore the association between BR and interoceptive sensibility (IS) throughout adulthood. One hundred thirty-seven healthy participants (50 aged from 18 to 40 years old; 50 aged from 41 to 60 years old; and 37 over 60 years old) were given a self-report tool for assessing IS (the Self-Awareness Questionnaire; SAQ), and a specific battery including tasks evaluating three different BR (i.

Objective: Systematic studies about the impact of unilateral brain damage on the different body representations (body schema, body structural representation, and body semantics) are still rare. Aim of this study was to evaluate body representation deficits in a relatively large sample of patients with unilateral brain damage and to investigate the impact of right or left brain damage on body representations (BRs), independently from deficits in other cognitive processes.

Method: Sixty-four patients with unilateral stroke (22 with left brain damage, LBD; 31 with right brain damage without neglect, RBD-N; 11 with right brain damage with neglect, RBD+N) and 41 healthy individuals underwent a specific battery including BR as well as control tasks.
