Disorders of the Nervous Tissue01:28

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...

Parkinson's Disease: Overview

2.2K
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Alterations in Muscle Tone ll

25
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...

Parkinson Disease ll: Pathophysiology

16
Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...

Hepatic Encephalopathy01:29

Hepatic Encephalopathy

26
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic...

Area of Science:

  • Neurology
  • Genetics
  • Cellular Biology

Background:

  • Mitochondrial diseases are systemic disorders impacting multiple organs, with the brain being the most frequently affected.
  • The brain's high energy demand makes it susceptible to mitochondrial dysfunction and energy failure.
  • These conditions can affect various neural components, including muscles, nerves, spinal cord, and brain.

Purpose of the Study:

  • To review primary genetic mitochondrial diseases affecting the nervous system.
  • To discuss the pathophysiology, clinical presentations, diagnostic approaches, and therapeutic strategies for these disorders.

Main Methods:

  • Literature review focusing on primary genetic mitochondrial diseases impacting energy production and the nervous system.
  • Synthesis of information on pathophysiology, phenotypes, diagnosis, and treatment.

Main Results:

  • Genetic causes include defects in nuclear genes and mitochondrial DNA (mtDNA).
  • Rapid advancements in exome and mtDNA sequencing are continuously identifying new gene defects.
  • Mitochondrial diseases manifest with diverse neurological phenotypes.
