Restoring brain barriers: an innovative approach for treating neurological disorders

Area of Science:

• Neuroscience
• Vascular Biology
• Neurology

Background:

• Neurological disorder etiology is complex, hindering therapeutic candidate identification.
• Brain vascular dysfunction is an emerging therapeutic strategy.
• Blood-brain barrier (BBB) and blood-spinal cord barrier (BSCB) alterations are implicated in neurological diseases.

Purpose of the Study:

• To quantify the prevalence of BBB/BSCB dysfunction in neurological diseases.
• To explore the clinical relevance of barrier status in patient outcomes.
• To review drug candidates targeting barrier repair.

Main Methods:

• Analysis of existing data on neurological diseases and barrier function.
• Review of clinical evidence linking barrier status to patient outcomes.
• Survey of drug development pipelines for barrier-targeting therapies.

Main Results:

• At least 41% of neurological diseases exhibit co-pathology of BBB/BSCB alterations.
• This figure likely underestimates the true prevalence of barrier dysfunction.
• Clinical data suggest barrier status significantly impacts pathological and functional outcomes.

Conclusions:

• BBB/BSCB dysfunction is a widespread and significant factor in neurological disorders.
• Targeting vascular repair presents a promising disease-modifying strategy.
• Further research and drug development are crucial for harnessing this therapeutic avenue.
