How much calcification are normal in brain ?
There shouldn’t be any calcification in the normal healthy brain. Tissues calcify when they are damaged. In the brain calcification can occur at the site of old bleeding (for example, an organising subdural haematoma). Individual neural cells can calcify if they have become damaged through oxygen deprivation. Viral infections occurring in the fetus such as cytomegalovirus can cause brain calcification and this can lead to a cerebral palsy like presentation after birth. This form of calcification is called ‘dystrophic’, meaning calcification occurring in abnormal tissues. The brain can also get calcification if there is a high level of calcium in the blood stream-this is called metastatic calcification.
