[Skin symptoms in neurological diseases]

Area of Science:

• Neurology
• Dermatology
• Genetics

Background:

• The skin and nervous system share a common developmental origin, leading to interconnected diseases.
• Nervous system disorders can manifest as diverse skin changes, affecting hair, nails, and glands.
• Neurocutaneous syndromes, such as neurofibromatosis and tuberous sclerosis, represent a group of systemic diseases impacting both systems.

Purpose of the Study:

• To review the spectrum of diseases affecting both the skin and the nervous system.
• To highlight the etiological factors and clinical manifestations of neurocutaneous disorders.
• To emphasize the importance of understanding the developmental link between skin and nervous system for diagnosis and management.

Main Methods:

• Literature review of neurocutaneous disorders and diseases with skin manifestations secondary to neurological conditions.
• Classification of polytopic disorders based on underlying causes (infectious, connective tissue, vascular, etc.).
• Analysis of the relationship between nervous system pathology and observable skin changes.

Main Results:

• Diseases of the nervous system frequently cause alterations in skin appendages (hair, nails, glands) and can lead to neuropathic ulcers.
• Neurocutaneous syndromes (phacomatoses) are congenital conditions with characteristic skin and neurological findings.
• Infectious, connective tissue, vascular, and granulomatous disorders can also present as polytopic diseases affecting both skin and nervous system.

Conclusions:

• The developmental linkage between the skin and nervous system underlies a wide array of associated diseases.
• Recognizing these connections is crucial for comprehensive diagnosis and treatment of patients with combined neurological and dermatological symptoms.
• Further research into the pathogenesis of these disorders can improve therapeutic strategies.
