Document Summary
Uncontrollable growth of cells that has no function: benign encapsulated tumor has distinct border b/w tumor and surround. A surgeon can remove it easily: malignant infiltrates the surrounding tissue. Can give rise to metastasis in which tumor cells go through the vascular system and grow elsewhere. Two ways: occupies space and compresses the tissue or block the flow of csf, the tumor invades the surrounding tissue as it grows and destroys the cells in it"s path. Glioma (tumors of the glial cells) is the most common and serious type of tumor. also: Partial seizures have a definite focus and remain localized. Complex partial seizures lead to loss of consciousness. Diagnosis relies on eeg, epilepsy is associated with bursts of high amplitude eeg spikes which occur during an attack. Simple seizures during sleep are not sleep disorders and occur during rem. A grand mal seizure is the most severe.
