Introduction to Stroke Flashcards
Why study stroke?
It is the 3rd leading cause of death after cancer and heart disease
To increase our understanding of the pathophysiology
Understand the impact that stroke can have on
- Healthcare system
- Families
- Individual
To develop effective prevention and intervention
Because it is interesting
Which areas of psychology can be related to stroke?
Neuroscience
Cognitive psychology
Sleep
Memory
Mood
Health psychology
Social psychology
- Relationship dynamics
- Personality
Clinical psychology
- Depression
What is the frontal lobe associated with?
Motor cortex
Judgement
Inhibition
Personality
Emotions
Language production
What is the parietal lobe associated with?
Sensory production
Orientation
What is the temporal lobe associated with?
Auditory perception
Memory
What is the brainstem associated with?
Regulation of autonomic function
Breathing
Heart function
What is the cerebellum associated with?
Coordination of movement
Posture
Balance
What is the occipital lobe associated with?
Vision
The brain requires how much of the body’s oxygen and how much of the cardiac output?
20% oxygen
15% cardiac output
What is a stroke?
An interruption to the blood supply in the brain
Causes significant cell death in the areas no longer receiving oxygen and nutrients
Classification of stroke
Ischaemic
Haemorrhagic
Transient Ischaemic Attack (TIA)
Ischaemic stroke
Most common
Blockage that stops the blood flow to the brain
Causes of ischaemic stroke
Cerebral thrombosis
Cerebral embolism
Systemic hyper perfusion
Cerebral thrombosis
Blood clot formed in one of the main arteries of the brain
Forms within the brain itself
What is an infarction?
An area of dead cells
Cerebral embolism
Blood clot forms in a different area of the body and travels up to the brain
What is the donor site?
Where the embolus formed
What is the recipient site?
Where the embolus gets stuck and causes a blockage
Systemic hypoperfusion
General reduction in blood supply around the body
Due to less cardiac output
Can affect all areas of the brain
Haemorrhagic stroke
Bleed into the brain
Types of haemorrhagic stroke
Intracerebral haemorrhage
Subarachnoid haemorrhage
Epidural haemorrhage
Intracerebral haemorrhage
Blood vessels deep within the brain erupt
Subarachnoid haemorrhage
Blood vessels have erupted between the brain and the skull
Bleeding occurs in the subarachnoid space
Epidural haemorrhage
Blood vessels have erupted between the brain and the skull
Bleeding occurs between the dura mater and the skull
