Multiple Sclerosis l: Introduction01:19

Multiple Sclerosis l: Introduction

5
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

Neural Regulation01:37

Neural Regulation

34.5K
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Cushing Syndrome II: Pathophysiology01:19

Cushing Syndrome II: Pathophysiology

4
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features...

Disorders of the Nervous Tissue01:28

Disorders of the Nervous Tissue

2.9K
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...

Peripheral Nervous System: Ganglia and Nerves

7.5K
The Peripheral Nervous System (PNS) is a crucial component of the body's neural network, extending beyond the central nervous system (CNS) to bridge the gap between the CNS and the external environment. It encompasses nerves, ganglia, and sensory receptors.
Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...

Neurogenesis and Regeneration of Nervous Tissue01:15

Neurogenesis and Regeneration of Nervous Tissue

2.0K
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Area of Science:

  • Neurology
  • Immunology
  • Pathology

Background:

  • Sarcoidosis is an idiopathic multisystem granulomatous disease.
  • Neurosarcoidosis presents with diverse neurologic symptoms, often mimicking other neurological conditions.
  • Accurate diagnosis is challenging due to the varied clinical presentation.

Purpose of the Study:

  • To review the varied neurologic manifestations of sarcoidosis.
  • To highlight syndromes associated with neurosarcoidosis to aid diagnosis.
  • To discuss diagnostic challenges and current/future treatment strategies.

Main Methods:

  • Literature review of neurosarcoidosis syndromes and diagnostic criteria.
  • Analysis of diagnostic approaches, including biopsy and imaging.
  • Overview of current and emerging treatment modalities.

Main Results:

  • Neurosarcoidosis diagnosis is complex, requiring integration of clinical, imaging, and biopsy data.
  • Definitive diagnosis requires noncaseating granulomas in neurologic tissue.
  • Probable diagnosis often relies on non-neurologic biopsy and characteristic findings.

Conclusions:

  • Understanding neurosarcoidosis syndromes is crucial for timely diagnosis.
  • Diagnostic strategies involve a combination of clinical suspicion, imaging, and tissue confirmation.
  • Advances in immunotherapy offer potential for more effective and safer treatments for neurosarcoidosis.
