Malignant gliomas
Contain tumour initiating cells from neural stem cells. Resistant to chemotherapy and radiation.
1 of 18
Bevacizumab
Retards growth of malignant tumours by restricting their formation of blood vessels.
2 of 18
Partial seizures
Localised as they begin with scar tissue, produce an aura and personality changes.
3 of 18
Complex partial seizures
Same as previous =, but can also produce profound effects on consciousness
4 of 18
Generalised seizures
Affect whole brain. Most serious type = grandmal convulsions. Caused by involvement of brain's motor systems.
5 of 18
Tonic phase
Rigidity/stiffening of muscles and loss of consciousness
6 of 18
Clonic phase
Rhythmic jerking and spasms. Rapid flexing and relaxing of head, legs and elbows. Followed by deep sigh, where they return consciousness.
7 of 18
Abstinence/heavy alcohol consumption induced seizures
Caused by a sudden release from inhibition
8 of 18
Seizure surgery
Used instead of anti-convulsant drugs for intractable seizure disorders, caused by abnormal focus. Usually involves medial temporal lobe.
9 of 18
Cerebrovascular accidents
Occur through ruptured blood vessel or occlusion of blood vessel through embolusn(debris lodged in artery) or thrombus (blood clot within vessel)
10 of 18
A lack of blood flow can damage neurons by stimulating big release of...
1.Glutamate-inflammation 2.Phagocytes-by activated microglia 3.Production of free-radicals 4.Activation of Calcium-dependent enzymes.
11 of 18
A metastatic oligodendrocytoma
A type of malignant tumour derived from glial cells
12 of 18
Anticonvulsant drugs work by
Enhancing the effectiveness of inhibitory synapses in the brain
13 of 18
What does prolonged interruption to blood supply result in?
Ischaemia
14 of 18
What is the main cause of neuron cell death after stroke?
Over stimulation of nerve cells by abnormally high synaptic levels of glutamate.
15 of 18
Degeneration of the caudate nucleus and putamen characterises which degenerative disorder?
Huntington's disease
16 of 18
Which drug has been shown to improve cognitive control in Alzheimer's disease?
Acetylcholinsterase inhibitor drugs
17 of 18
The etiology of MS may involve what?
Damage to the blood-brain barrier by a virus.
