Summary
Turner syndrome (TS) involves sex chromosome loss, impacting cognition and neurodevelopment. Research reveals brain function differences and identifies needs for better understanding and interventions for TS patients.
Area of Science:
- Neuroscience
- Genetics
- Developmental Biology
Background:
- Turner syndrome results from partial or complete loss of a sex chromosome.
- Individuals with TS exhibit distinct cognitive profiles and neurodevelopmental risks.
- Understanding brain alterations in TS is crucial for targeted interventions.
Purpose of the Study:
- Review recent advancements in brain structure and function research in Turner syndrome.
- Identify critical areas requiring further investigation.
- Highlight potential therapeutic avenues for individuals with TS.
Main Methods:
- Review of current neuroimaging studies and genetic analyses.
- Synthesis of findings on cognitive and social functioning.
- Analysis of potential etiological mechanisms.
Main Results:
- Difficulties in social cognition persist despite intact social interest in TS.
- Deficits in attention and executive function correlate with visual-spatial and arithmetic impairments.
- Neuroimaging reveals altered brain development, potentially linked to genetic and hormonal factors.
Conclusions:
- Further research is needed to connect specific molecular mechanisms to observed phenotypes in TS.
- Intervention studies are required to improve visual-spatial, mathematical, and social skills.
- Enhanced understanding of brain function in TS will drive novel therapeutic strategies.

01:27Language and Cognition
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.
01:17Cognitivism
Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process information is...

01:14Brain Imaging
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

01:20Introduction to Cognitive Psychology
Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing.

01:24Revisionist Views of Adolescent and Adult Cognition
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are themselves.
01:23Alzheimer Disease ll: Pathophysiology
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
