Association Areas of the Cortex01:21

Association Areas of the Cortex

8.5K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Freudian Psychology

2.0K
Sigmund Freud, an Austrian neurologist born in 1856, significantly influenced psychology through his exploration of the unconscious mind. His interest in patients suffering from hysteria and neurosis — conditions without apparent physical causes — led him to theorize the existence of an unconscious mind, a repository for feelings and urges beyond our awareness. Freud's innovative approach included techniques such as dream analysis, free association, and attention to slips of the...

Skin Diseases and Disorders

5.1K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Dissociative Identity Disorder01:30

Dissociative Identity Disorder

528
Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...

Major Somatic Sensory Pathways01:28

Major Somatic Sensory Pathways

2.2K
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

Psychosexual Theory of Development01:14

Psychosexual Theory of Development

1.9K
Sigmund Freud's psychosexual theory of development suggests that early childhood experiences significantly shape personality and behavior. Freud proposed that development is discontinuous, occurring in five distinct stages, each defined by a focus on different erogenous zones. He believed that failure to resolve the conflicts specific to each stage successfully could result in fixation, potentially influencing behavior as adults.

    Summary

    The connection between skin itch and mental state is bidirectional, influencing overall health. Understanding this complex relationship is key to improving patient well-being through integrated care.

    Area of Science:

    • Dermatology
    • Psychiatry
    • Neuroscience

    Background:

    • Skin and psyche are intrinsically linked from embryological development, affecting physiological state across all ages.
    • The relationship between itch and psyche is bilateral; disruptions in one impact the other.
    • Itch pathogenesis is complex, involving peripheral and central nervous systems and inflammatory mediators.

    Purpose of the Study:

    • To review key aspects of itch pathogenesis.
    • To explore associations between itch, stress, and psychological factors.
    • To discuss the impact of itch on quality of life and social stigma.

    Main Methods:

    • Literature review of itch pathogenesis.
    • Analysis of psychological and psychiatric considerations in itch.
    Keywords:
    itch, psyche, pathogenesis, stress, psychiatry, burden of disease

  • Examination of health-related quality of life (HRQoL) and stigmatization in patients with itch.

    • Main Results:

    • The itch-psyche connection is complex and bidirectional.
    • Stress and psychological factors significantly influence itch perception and experience.
    • Chronic itch severely impairs health-related quality of life (HRQoL) and can lead to stigmatization.

    Conclusions:

    • Despite unanswered questions, current knowledge highlights the importance of the itch-psyche link.
    • A holistic, interdisciplinary approach is crucial for managing patients with itch.
    • Improving patient well-being requires addressing both dermatological and psychological aspects of itch.
