[Neurologic concomitant diseases in Crohn disease]

Area of Science:

• Neurology
• Gastroenterology
• Internal Medicine

Context:

• Crohn's disease is a chronic inflammatory condition affecting the gastrointestinal tract.
• Neurological complications can arise directly from Crohn's disease or its therapeutic interventions.
• Understanding these neurological manifestations is crucial for comprehensive patient care.

Purpose:

• To review and synthesize the known central and peripheral nervous system disturbances associated with Crohn's disease.
• To differentiate between disease-related and treatment-related neurological complications.
• To highlight the clinical presentation, potential causes, and management considerations for these neurological issues.

Summary:

• Neurological disturbances in Crohn's disease encompass a range of conditions, including cerebral thromboses due to hypercoagulation, subacute combined degeneration from vitamin deficiencies, and optic neuropathies.
• Drug-induced neurological issues, particularly sensory polyneuropathy and cerebral dysfunction from metronidazole, are significant concerns, often requiring prolonged recovery.
• Non-drug-induced polyneuropathies may present as mononeuritis multiplex or sensory neuropathy, potentially linked to autoimmune processes.

Impact:

• Provides a comprehensive overview of neurological complications in Crohn's disease for clinicians and researchers.
• Emphasizes the importance of monitoring for and managing neurological side effects of Crohn's disease treatments.
• Contributes to improved diagnostic and therapeutic strategies for patients with Crohn's disease and associated neurological conditions.
