Summary
Oral inositol supplements significantly boost cerebrospinal fluid (CSF) levels, challenging the blood-brain barrier
Area of Science:
- Biochemistry
- Neuroscience
- Pharmacology
Background:
- Inositol is vital for phosphatidylinositol synthesis and second messenger signaling.
- Inositol's biological activity is noted in conditions like respiratory distress syndrome.
- The central nervous system (CNS) was previously thought to be inaccessible to inositol due to the blood-brain barrier.
Purpose of the Study:
- To investigate the effect of oral inositol on CNS inositol levels.
- To assess the potential for inositol to cross the blood-brain barrier.
- To explore therapeutic and side-effect implications of systemic inositol administration in the CNS.
Main Methods:
- Oral administration of inositol to a cohort of 8 patients.
- Measurement of inositol levels in cerebrospinal fluid (CSF) before and after treatment.
Main Results:
- Oral inositol intake led to a significant increase in CSF inositol concentrations.
- CSF inositol levels rose by nearly 70% following oral supplementation.
- Demonstrated that inositol can indeed cross the blood-brain barrier.
Conclusions:
- Systemic inositol administration effectively increases CNS inositol levels.
- This finding suggests potential therapeutic applications for inositol within the CNS.
- Highlights the possibility of unintended CNS side-effects from systemic inositol therapy.
