Autoimmune Disorders01:29

Autoimmune Disorders

2.1K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

2.4K
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Disorders of the Nervous Tissue

3.0K
Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.

Myasthenia Gravis: Overview and Treatment

3.4K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Disorders of the Autonomic Nervous System

1.9K
The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.

Gut-Brain Axis01:22

Gut-Brain Axis

30
The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such...

Area of Science:

  • Neuroimmunology
  • Psychiatry
  • Neurology

Background:

  • Decades of research suggest immune system involvement in neuropsychiatric disorder pathophysiology.
  • Previous genetic, epidemiologic, and immunologic findings have not translated into clinical practice.
  • Recent advances in understanding autoimmune central nervous system (CNS) disorders prompt investigation into antibody-mediated psychiatric illnesses.

Purpose of the Study:

  • To review the current understanding of autoimmune CNS disorders.
  • To explore the relevance of autoimmune CNS disorders to psychiatric conditions, specifically schizophrenia and autism.
  • To assess the potential clinical utility of antibody screening in psychiatric patient groups.

Main Methods:

  • Review of existing literature on autoimmune CNS disorders.
  • Analysis of antibody screening results in psychiatric patient cohorts.
  • Discussion of future research directions.

Main Results:

  • Suggestive evidence links immune system dysregulation to neuropsychiatric disorders.
  • Identification of antibody-mediated CNS disorders offers a new perspective.
  • Preliminary antibody screening data in psychiatric patients are being evaluated.

Conclusions:

  • Autoimmune CNS disorders may represent a distinct subgroup of psychiatric illnesses.
  • Further research is needed to validate antibody screening findings for clinical application.
  • Establishing a definitive link between autoimmune mechanisms and psychiatric disorders requires more investigation.
