[Autonomic peripheral neuropathy].

Area of Science:

• Neurology
• Autonomic Nervous System Research
• Peripheral Neuropathy Studies

Background:

• Dysautonomic disturbances are primarily acquired, stemming from damage to sympathetic or parasympathetic nerve fibers or ganglia.
• Peripheral neuropathies, both chronic and acute, are frequently associated with dysautonomia.
• While many causes exist, diabetic dysautonomia is the most prevalent globally, significantly impacting cardiovascular health and survival.

Purpose of the Study:

• To review the diverse mechanisms and causes of dysautonomic disturbances.
• To highlight the clinical significance of identifying specific causes of dysautonomia.
• To discuss diagnostic approaches and treatment strategies for autonomic neuropathies.

Main Methods:

• Review of existing literature on dysautonomia and peripheral neuropathies.
• Analysis of etiological factors, including acquired and hereditary conditions.
• Discussion of diagnostic confirmation methods, such as molecular biology.
• Examination of treatment implications, focusing on symptomatic relief and causal therapies.

Main Results:

• Dysautonomia mechanisms are varied, involving lesions in peripheral nerve fibers, ganglia, demyelination, or axonal loss.
• Diabetes is the leading cause of dysautonomia worldwide, with severe cardiovascular dysfunction affecting prognosis.
• Rare hereditary forms, like Riley-Day syndrome and transthyretin amyloid polyneuropathies, exist and can be diagnosed via molecular biology.

Conclusions:

• Dysautonomia is a frequent and often severe complication of peripheral neuropathies.
• Identifying the underlying cause is critical for clinical management and potential disease modification.
• Symptomatic treatments are essential for improving quality of life, while specific therapies can target causal factors to halt disease progression.
