It would be extraordinary if all of our body could fight
have barriers that could keep us safe from harmful viruses. The blood brain barrier is a great defense
built for our brain but at the same time it has its flaws. It protects our brain by avoiding any
dangerous viruses to affect our nervous system.
The only problem comes when it avoids medication that can be used for
neurological diseases. The same manner
the blood brain barrier protects our nervous system and our brain, it brings
its disadvantages. The blood brain
barrier helps in many ways in a person’s health.
Scientists have been researching for ways for the blood brain barrier to
stay open so it could allow medication needed to improve diseases that involve
brain activity. There has been couple of
research where they have applied experiments on mice to try to find a way to
keep the barrier open for some seconds to allow certain medication to go
through to treat certain diseases such as brain cancer.
About a year ago, there was a break in the finding of this
complicated problem allowing for treatments for Alzheimer’s disease, multiple sclerosis,
and other cancers that affect the nervous system. It has been difficult for a research to have
a positive outcome. With this advance in
science, there will be positive outcomes for patients who have gone by many
treatments that have not worked due to the medication that was not able to
reach the brain for success treatment.
I thought this concept was interesting too, how our body fights the viruses but then again prevents certain medications from working for our bodies against some diseases. It will take trial and error to find the correct medications that can pass through the barrier.
