A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze...

Explicit Memories01:27

Explicit Memories

527
Explicit memories, also known as declarative memories, are consciously remembered, recalled, and reported. Studying for a chemistry exam involves material that will become part of explicit memory. There are two types of explicit memory: episodic and semantic.
Episodic memory contains information about personally experienced events and is reported as a story. An example of episodic memory is recalling a birthday celebration. This type of memory includes the what, where, and when of an event, as...

Encoding01:19

Encoding

950
Information enters the brain through encoding, which is the input of information into the memory system. Once sensory information is received from the environment, the brain labels or codes it. The information is then organized with similar information and connected to existing concepts. Encoding occurs through automatic processing and effortful processing.
Automatic processing involves the encoding of details like time, space, frequency, and the meaning of words, usually done without conscious...

Impact of Schemas01:30

Impact of Schemas

248
Schemas are cognitive structures that provide a framework for interpreting and organizing social information. They help individuals navigate complex environments by offering expectations about people, events, and behaviors. Schemas influence attention, encoding, and retrieval processes, thereby shaping the entire trajectory of information processing in social contexts.Attention and Cognitive LoadDuring initial attention, schemas function as filters that prioritize schema-consistent information,...

Schemas

A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Concepts and Prototypes01:24

Concepts and Prototypes

606
The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
The brain organizes this information using concepts, which are mental categories grouping linguistic data,...

Area of Science:

  • Neuroscience
  • Neurology
  • Geriatrics

Background:

  • Dementia affects millions globally, posing significant social and economic burdens.
  • Semantic dementia (SD), also known as the semantic variant of primary progressive aphasia, is a form of frontotemporal dementia (FTD).
  • Maintaining patient-caregiver quality of life is crucial, with communication being a key factor.

Purpose of the Study:

  • To explore semantic dementia (SD), a specific form of frontotemporal dementia (FTD).
  • To provide current information on the diagnosis and treatment of SD.
  • To highlight the importance of quality of life for patients and caregivers.

Main Methods:

  • A mini-review methodology was employed.
  • Literature search conducted in major databases (Web of Science, PubMed, Springer, Scopus) from 2000 to 2015.
  • Selected studies were compared and evaluated.

Main Results:

  • FTD, including SD, is a severe neurodegenerative disorder with fatal outcomes.
  • Pharmacological treatment options for SD are limited.
  • Non-pharmacological interventions warrant increased attention.

Conclusions:

  • Semantic dementia is a rare but devastating neurodegenerative disorder.
  • The condition has irreversible effects on the quality of life for both patients and their caregivers.
  • Further research into non-pharmacological treatments is essential.
