Document Summary
Major categories of the neuropathological conditions that the brain can sustain: tumors, seizure disorders, cerebrovascular accidents, disorders of development, degenerative disorders, disorders caused by infectious disease. Tumors: a tumor is a mass of cells whose growth is uncontrolled and that serves no useful function. If the border exists, tumor is benign; surgeon can cut it out and it will not regrow. If the tumor grows by infiltrating the surrounding tissue, there will be no clear-cut border between the tumor and the normal tissue. Gliomas glioblastoma multiforme (poorly differentiated glial cells) astrocytoma (astrocytes) Ependymoma (ependymal cells that line ventricles) medulloblastoma (cells in roof of fourth ventricle) oligodendrocytoma (oligodendrocytes) Pituitary adenoma (hormone-secreting cells of the pituitary gland) Neurinoma (schwann cells or cells of connective tissue covering cranial nerves) Metastatic carcinoma (depends on the nature of the primary tumor) Seizure disorder - preferred term for epilepsy: has many causes, 2nd most important category of neurological disorders - following stroke.
