Narcolepsy01:07

Narcolepsy

584
Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.

Hypothalamic-Pituitary Axis01:37

Hypothalamic-Pituitary Axis

66.3K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

The Evidence for Evolution02:55

The Evidence for Evolution

48.3K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Self-Presentation01:25

Self-Presentation

325
Self-presentation is a fundamental aspect of social interaction, shaping both how others perceive individuals and how they view themselves. This dynamic process influences behaviors in various social settings, often leading people to adjust their appearance, speech, and demeanor to align with their desired identity. While self-presentation can be deliberate or unconscious, it plays a critical role in interpersonal relationships and self-perception.Forms of Self-PresentationSelf-presentation can...

Convergent Evolution01:54

Convergent Evolution

33.0K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

Self-Presentation: Self-Monitoring and Self-Handicapping02:05

Self-Presentation: Self-Monitoring and Self-Handicapping

44.8K
People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Area of Science:

  • Neurology
  • Neuro-oncology
  • Sleep Medicine

Background:

  • Narcolepsy associated with brain tumors is rare, with limited data on its presentation and progression.
  • This study aims to elucidate the epidemiology, etiology, and outcomes of narcolepsy linked to brain tumors.

Observation:

  • A literature review identified 25 cases of narcolepsy associated with hypothalamic brain tumors.
  • The majority of symptomatic cases (70%) occurred in children.
  • Narcolepsy onset was observed post-surgery in 52% of patients and at tumor diagnosis in 44%.

Findings:

  • Craniopharyngioma (38%), adenoma (24%), and glioma (14%) were the most common associated tumors.
  • Ten patients presented with narcolepsy without cataplexy.
  • Complete symptom resolution occurred in three patients; 60% of those with persistent symptoms improved with medical management.

Implications:

  • This compilation provides the largest dataset on brain tumor-related narcolepsy, enhancing understanding of its causes and prognosis.
  • Findings suggest that hypothalamic tumors are a significant, though uncommon, cause of narcolepsy, especially in pediatric populations.
  • Effective management strategies exist for persistent symptoms, improving patient outcomes.
