microbiota-gut-brain axis, which is the relationship between bacteria in the gut and how the brain functions.According to one article, CA are a type of abnormal blood vessel in a person’s brain.
Estimates show that 0.5% of the population has them. Of these, 40% become symptomatic, sometimes due to the vessel hemorrhaging.
Symptoms can include headaches, visual disturbances, seizures, or stroke.Doctors can monitor CA with frequent magnetic resonance imaging (MRI) scans.
Some people may require surgery. Scientists know that CA have a genetic component, so a person may inherit certain gene variants that make developing CA more likely.However, previous research on mice has shown that the gut microbiome may also affect CA.
