Neurological diseases & disorders Flashcards
(18 cards)
Occurs when the brain is deprived of blood, which carries oxygen and nutrients to the brain:
Stroke
Type of stroke that is caused by a blood clot/blockage:
Ischemic
Type of stroke caused by a blot clot/blockage which is localised to the brain:
Thrombotic
Type of stroke caused by a blood clot/blockage which is formed elsewhere in the circulatory system (i.e. not in the brain):
Embolic
Type of stroke caused by a ruptured blood vessel:
Hemorrhagic
Type of stroke caused by an abnormal, ballon-like “bulge” in the blood vessel:
Aneurysm
A congenital disorder that causes rupture and brain bleed:
Arteriovenous malformation (AVM)
A ____ ischemic stroke occurs when the obstruction is short-lived and can be quick to recover from if help is sought in time:
Transient
Structural neuroimaging methods that are used to diagnose stroke based on location of tissue damage:
(Hint: there are 2!)
CT & MRI
Name the substance that fills in dead tissue after a stroke:
Cerebrospinal fluid (CSF)
Structural neuroimaging method that is used to detect and diagnose abnormalities in the blood:
Angiography
An epileptic event where the senses are momentarily disrupted due to brief electrical disturbances in the brain:
Seizure
Seizures are diagnosed using:
EEG
Diagnosing seizures using EEG is challenging because:
a) EEG is usually unaffordable
b) the person must be unconscious while hooked up to the machine
c) the person must be actively seizing while hooked up to the machine
c) the person must be actively seizing while hooked up to the machine
What might we expect to see on an EEG if someone is experiencing seizure activity?
Spikes and waves
____ seizures involve the whole brain:
Generalised
____ seizures are localised to one part of the brain:
Partial
Seizures are caused by epilepsy, which may be caused by a stroke or:
Tumour
