Brain Tumors (Notes) Flashcards
Common aim of medications for those with brain tumors
Managing elevated intracranial pressure
How are those with brain tumors similar to those with TBIs and stroke?
The rehabilitation approach and outcomes are similar
Describe the cells associated with benign tumors
Well-differentiated
Describe the cells associated with malignant tumors
Non-differentiated
Why are benign tumors still a problem?
Because they cause an increase in ICP
Consequences of elevated intracranial pressure
Headaches
Nausea/vomiting
Seizures
Altered mental status
“Function” of the tentorium cerebelli
It splits the skull into an anterior and posterior chamber
Residents of the anterior chamber of the skull
It contains the cerebral hemispheres
Residents of the posterior chamber of the skull
The brain stem and cerebellum
Name of tumors located in the anterior chamber of the skull
Supratentorial lesions
Name of tumors located in the posterior chamber of the skull
Infratentorial lesions
2 things we need to know about primary malignant tumors that we discussed in class
They develop within the brain tissue (parenchyma of the CNS)
They have a grade assigned by the WHO that helps aid in their diagnoses
Reason why tumors do not originate from neurons
Neurons have left the mitotic cycle and they do not have the ability to regenerate
The difference between grade 2 and grade 3 primary malignant tumors
The rate of cell proliferation, the survival rate, and the prognosis associated between them
Commonality between most grade 3 primary malignant tumors
They have the term anaplastic associated with it
Define anaplastic
A word used to describe a cell that has lost the morphological characteristics of a mature cell
Origin of primary tumors (general)
Brain tissue or within the vertebral column
Origin of primary malignant tumors
Parenchyma of the CNS
Origin of primary benign tumors
The cranial vault or the vertebral canal
does not develop within the tissue of the brain
Another name for primary benign tumors
Extra-axial tumors
The most aggressive and most common tumor in older adults
Glioblastoma
Why would a tumor originating from the vestibular portion of CN8 cause hearing loss?
Because the vestibular system is so successful at adapting to slow changes that occur in the peripheral system while the auditory system in unable to adapt to the same degree
