social cognition and language in patients with gliomas

Conditions: Glioma, Malignant; Cognitive Dysfunction

Summary: patients with gliomas often suffer from lower quality of life, and detrimental social interactions after diagnosis. two cognitive processes are crucial for maintaining healthy social relationships and interacting with others: social cognition and language. social cognition is the ability to recognize and process mental and emotional states and to react appropriately in social situations. social cognition and language are separate cognitive functions that can be affected in different ways in patients with brain injury. also, distinct cognitive measurement instruments are used to assess both processes. however, there appears to be a certain overlap between social cognition and language. reacting adequately in social situations requires both verbal and non-verbal communication and to communicate feelings, thoughts and intentions, people often use language. that is, verbal communication is part of a symbolic system that makes social interaction possible. therefore, language abilities seem to be important to social cognition. research shows that language is frequently impaired in adult patients with gliomas. importantly, recent evidence suggests that social cognition can also be impaired in this patient group. however, no studies have been conducted into the relationship between social cognition and language in patients with gliomas. increasing knowledge on the overlap between both functions, more specifically the influence of language difficulties on social cognition, will improve diagnostic accuracy. eventually, this will lead to better, tailor-made treatments for these problems that negatively affect daily functioning. objective: the main research objective is to examine the influence of language impairments on different social cognition processes, i.e., emotion recognition, theory of mind (tom) and affective empathy, in patients with (suspected) gliomas. secondary objectives are 1) to determine if patients with gliomas show impairments in different aspects of social cognition, i.e. emotion recognition, tom, empathy and self-awareness; 2) to assess specific language impairments by looking at item-level characteristics of language tasks (e.g., analyses of word properties of fluency tasks, errors during object naming or spontaneous speech), and 3) to determine which tumor characteristics (low- or high-grade, genetic mutation, tumor location) are associated with different aspects of language and social cognition.
