Peripheral nervous system manifestations in systemic autoimmune diseases

Area of Science:

• Neurology
• Immunology
• Systemic Autoimmune Diseases

Background:

• The peripheral nervous system (PNS) comprises nerves outside the brain and spinal cord.
• Systemic autoimmune diseases can affect the nervous system through diverse mechanisms.
• Neurological complications of these diseases contribute significantly to morbidity and mortality.

Purpose of the Study:

• To summarize the impact of systemic autoimmune diseases on the peripheral nervous system.
• To highlight the common neurological complication, peripheral neuropathy.
• To describe the varied clinical manifestations and presentation patterns of PNS involvement.

Main Methods:

• Literature review on autoimmune diseases and neurological complications.
• Analysis of clinical presentations associated with PNS involvement.
• Categorization of peripheral neuropathy types (multifocal, asymmetric, distal, symmetric).

Main Results:

• Peripheral neuropathy is the most frequent complication of PNS involvement in systemic autoimmune diseases.
• Symptoms include numbness, sensory paresthesias, weakness, and gait imbalance.
• Neuropathy can manifest as multifocal and asymmetric or distal and symmetric patterns.

Conclusions:

• Systemic autoimmune diseases pose a significant threat to peripheral nervous system integrity.
• Prompt recognition and management of peripheral neuropathy are crucial for patient outcomes.
• Understanding the heterogeneous mechanisms and manifestations is key to addressing neurological complications.
