Multiple Sclerosis l: Introduction01:19

Multiple Sclerosis l: Introduction

19
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...

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.
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...

Disorders of the Skeletal Muscle

2.2K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Neural Regulation

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.

Alterations in Muscle Tone ll

26
Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...

Secondary Spinal Cord Injury llI: Pathophysiology

51
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

Area of Science:

  • Neurology
  • Immunology
  • Neuroscience

Background:

  • Inflammatory demyelinating diseases (IDDs) of the central nervous system (CNS) are diverse and incompletely classified.
  • Current classification of IDDs may not encompass all clinical presentations.

Purpose of the Study:

  • To describe a cohort of patients with progressive myelopathy linked to a solitary spinal cord demyelinating lesion.
  • To identify patients with chronic spinal cord dysfunction and a single lesion not meeting criteria for established IDDs.

Main Methods:

  • Retrospective identification of patients with chronic progressive spinal cord dysfunction and a single spinal cord lesion.
  • Magnetic resonance imaging (MRI) and cerebrospinal fluid (CSF) analysis were performed.
  • Diagnostic criteria for established IDDs were assessed.

Main Results:

  • Eight patients (7 female, 1 male) with a median age of 53 were studied.
  • MRI revealed single, non-enhancing cervical cord lesions; CSF showed no oligoclonal bands or elevated IgG.
  • Some patients responded to immunosuppressive therapy, and no new lesions developed on follow-up MRI.

Conclusions:

  • The findings suggest the existence of new entities or variants within IDDs.
  • Further characterization of these cases is crucial for accurate prognosis and therapeutic strategies.
