PSYCH 202 Chapter Notes - Chapter pg 528-537: Taenia Solium, Partial Seizure, Neurocysticercosis
Document Summary
*explain what a brain tumor is, and differentiate between types of tumors. Tumor: independent growth of tissue that lacks purpose. Malignant tumor: abnormal cell growth that lacks boundaries and invades the surrounding tissue and is very likely to recur following surgical removal. Benign tumor: abnormal cell growth that develops within its own membrane and is unlikely to recur following surgical removal. Gliomas: develop in glial cells and account for +70% of brain tumors. Meningiomas: tumors that arise within the tissues of the meninges. Chemotherapy: challenging for use with brain tumors because chemotherapy agents do not cross the blood-brain barrier. *identify and distinguish between parasitic, bacterial, viral, and fungal brain infections. Neurocysticercosis: most common; brain cysts resulting from pork tapeworm: solium. Encephalitis: inflammation of brain caused by viral infection. West nile virus: encephalitis causing virus that is carried by birds and transmitted to humans via mosquitoes. Identify and explain the different types of seizures including the symptoms.
