Disorders of the Nervous Tissue

1.9K
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.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.
Parkinson's disease arises from the...

Brain Imaging

362
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...

Organization of the Brain

1.4K
The brain is an integral component of the nervous system and serves as the center for processing sensory inputs, making decisions, and directing bodily actions. This complex organ is organized into three primary sections: the hindbrain, midbrain, and forebrain, each responsible for a range of vital functions.
Hindbrain
The hindbrain, located at the base of the brain, plays a vital role in regulating automatic processes that sustain life. It includes the medulla oblongata, which is essential for...

Role of Cerebellum and Prefrontal Cortex in Memory01:14

Role of Cerebellum and Prefrontal Cortex in Memory

634
The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the...

Alzheimer's Disease: Overview01:26

Alzheimer's Disease: Overview

716
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

    Summary

    Long covid neurological symptoms, like brain fog, may stem from immune responses. This suggests these debilitating effects could be reversible with appropriate treatment.

    Area of Science:

    • Neurology
    • Immunology
    • Infectious Diseases

    Background:

    • Long covid is a complex condition with persistent neurological symptoms.
    • Brain fog and other cognitive impairments significantly impact patients' quality of life.

    Purpose of the Study:

    • To investigate the underlying mechanisms of long covid neurological symptoms.
    • To explore the potential for reversibility of these symptoms.

    Main Methods:

    • Review of latest scientific evidence.
    • Analysis of immunological markers associated with neurological dysfunction.
    • Correlation of immune reactions with reported symptoms.

    Main Results:

    • Emerging evidence points to an immune reaction as the cause of neurological symptoms in long covid.

  • These symptoms, including brain fog, show potential for reversal.

    • Conclusions:

    • Neurological manifestations of long covid are likely driven by the immune system.
    • Therapeutic strategies targeting immune responses may offer a path to recovery for affected individuals.
