Disorders of the Nervous Tissue01:28

Disorders of the Nervous Tissue

2.3K
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.

Chemical Synapses01:26

Chemical Synapses

11.0K
Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

Local Anesthetics: Differential Sensitivity of Nerve Fibers01:24

Local Anesthetics: Differential Sensitivity of Nerve Fibers

1.3K
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

Local Anesthetics: Adverse Effects01:12

Local Anesthetics: Adverse Effects

681
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

Antiepileptic Drugs: Glutamate Antagonists01:14

Antiepileptic Drugs: Glutamate Antagonists

776
Glutamate is a fundamental neurotransmitter in the central nervous system, playing a vital role in neuronal communication and various cognitive processes. Glutamate stands as the principal excitatory neurotransmitter in the brain. Its presence is crucial for the communication between neurons, underpinning essential processes such as synaptic transmission, neuronal excitability, and plasticity. These functions are vital for higher-order cognitive processes, including learning and memory. The...

Area of Science:

  • Neurology
  • Neuroscience
  • Peripheral Nervous System Disorders

Background:

  • Ataxia is a common neurological symptom with numerous causes.
  • Sensory ataxia results from proprioceptive pathway dysfunction, affecting the central or peripheral nervous system.
  • Ataxic neuropathies specifically involve peripheral nervous system disorders.

Purpose of the Study:

  • To present the main causes of ataxic neuropathies.
  • To outline diagnostic workflows for identifying these conditions.
  • To correlate diagnostic approaches with lesion topography and symptom onset.

Main Methods:

  • Reviewing and synthesizing information on the etiologies of ataxic neuropathies.
  • Proposing diagnostic strategies based on the location of lesions within the proprioceptive pathway.
  • Considering the temporal profile of symptom development (acute, subacute, chronic).

Main Results:

  • Ataxic neuropathies are a heterogeneous group of disorders.
  • Etiologies can affect various parts of the peripheral nervous system, including dorsal root nerves, ganglia, nerve trunks, and distal endings.
  • Diagnostic workflows are guided by anatomical localization and clinical timing.

Conclusions:

  • Predominant sensory ataxia in peripheral neuropathy suggests specific underlying causes.
  • A structured diagnostic approach is crucial for identifying the etiology of ataxic neuropathies.
  • Understanding lesion site and timing aids in differentiating various causes.
