There is no danger of having calcified spots on the brain because many people may develop physiological calcifications as they age. This is usually caused by abnormal calcium deposition. Many elderly people will find physiological calcifications in the choroid plexus, the pineal region, the basal ganglia, and the falx cerebri when they have a CT examination of the head, which is a normal physiological phenomenon. In many other people, when the parasitic worms die after a long period of time, calcification will be formed in the brain, which is not dangerous because there are no symptoms in the clinic. However, if a patient has a calcified spot, it is considered to be caused by a glioblastoma, which should be noticed because it can easily lead to seizures and needs to be treated promptly.
