For the treatment of calcified foci in the brain: first, the cause of the calcified foci in the brain should be found. Most of the calcification foci in the brain are found during CT examination, and most of them are functional without organic disease manifestations, especially the calcification of the choroid plexus, which can appear with the deposition of trace elements in the brain tissue as people grow older. Secondly, there are some clinical diseases that can show calcified foci in the brain, such as abnormal thyroid function, and patients can develop this Hashimoto’s encephalopathy, which can be manifested as bilateral calcified foci in the basal ganglia. In this case, the patient should be given active treatment of thyroid function, such as oral treatment with Sage in case of hyperthyroidism and oral treatment with Eugenol in case of hypothyroidism, along with medication to improve brain nerve function. Finally, calcification foci in the brain can also be seen clinically in delayed encephalopathy after carbon monoxide poisoning. If necessary, the patient can be given hyperbaric oxygen therapy, which can also be combined with drugs that nourish brain cells and improve brain metabolism, such as cerebroprotein hydrolysate tablets and cytarabine tablets. In some patients, the calcification foci are left after the death of cysticercus cerebri, which is recommended to be reviewed in a year or so without treatment.
