Deficiency in the generation of speech
What are the 3 contralateral issues that can occur when you damage the sensory cortex?
1 loss of sensation
3 hyperaesthesia (excessive sensation = pain syndrome)
What issues can occur due to damage to the higher level eg frontal lobe?
Sequencing problem (dyspraxia)
What are the 3 types of vision loss?
1 monocular vision
3 visual neglect
What is hemianopia?
Blindness over half of the vision field
Damage to the cerebellum causes...3 things
Loss of co-ordination
Ataxia (intention tremor & cerebellar gait)
Dysarthria - speech problems
What does the basal ganglia control? Damage results on what?
- increased muscle tone
- slowness of action

Define a stroke
Disorder of the vascular supply of the brain
What are 90% of strokes? 10% are..
Infarction ( atherosclerosis and cardiac emboli )
What is focal neurology?
The effect of brain injury
what are the 2 types of infarction type strokes?
- transient ischaemic attack (TIA)
- completed stroke
what is a TIA?
a small stroke where symptoms resolve within 24hrs that requires urgent medical attention to reduce risk of permanent stroke
what is a completed stroke?
persisiting neurological deficit
are haemorragic strokes usually more or less severe than infarction type strokes?
what is the main risk factors for haemorragic stroke?
what is the epidemiology of strokes?
- incidence increases with age
- 1% each year aged 75
what are the clinical features of a stroke dependant upon?
