What is the Blood-Brain Barrier (BBB)?

The BBB is a semi-permeable membrane (of glial cells) which protects the Central Nervous System (brain & spinal cord) from toxins and changes in blood composition.

The BBB can be broken down by high blood pressure, microwaves, hyperosmolitity, radiation, infection, trauma, inflammation, schema, and pressure.

BBB dysfunction can lead to neural damage. Diseases such as MS, encephalitis, stroke, or tumours can also damage the BBB.

The brain is metabolically one of the most active of all organs in the body. The brain does not store energy so it therefore needs a continuous supply of glucose and oxygen to meet it's energy requirements.
