Lecture: Cognition Flashcards
what is perception?
the integration of sensory inputs into meaningful information
what is cognition?
ability to process, sort, retrieve and manipulate information
what factors influence the relationship between a physiological lesion in the brain and the result on the patient psychologically?
- size and depth of lesion
- if there is a combination of deficits
- if the lesion is unilateral or bilateral
- some functions cannot be topographically limited.
what type of clientele may have a cognitive element to their condition?
- acquired brain injury (caused by TBIs, infections, CVAs, aneurysms, tumours, hypoxia, anoxia…)
- psychiatric disorders
- genetic/developmental disorders
- senile dementia & Alzheimer’s disease
what are the three most common emotional-behavioural difficulties following acquired brain injuries?
- apathy
- depression
- anxiety
ABIs can be focal or diffuse. Which types are often diffuse?
hypoxia, anoxia…
what would be considered a mild TBI on the glasgow coma scale?
13-15
What is considered a severe TBI on the Glasgow Coma Scale?
< 8 for 6+ hours
Stroke increases the incidence of which cognitive disease?
Alzeimers
Cover and Overt strokes have the same symptoms (T/F)
F - covert stroke will not have the classical symptoms, and the person probably won’t even go to the doctor.
Which of the three pathogenic concepts of VCIs involves many small lesions adding together to result in cortical dementia syndrome?
accumulated cortical infarcts
which type of VCI results in dementia due to small and isolated lesions in important brain areas such as the thalamus (disruption connections between prefrontal cortex and basal ganglia or thalamus)?
Strategic subcortical infarcts.
which type of VCI involves lesions of white matter?
functional cortical disconnection
what deficits might you observe with a ACA stroke?
hemiplegia
sensory loss
a lesion in which artery will result in confusion, impaired memory and new learning, and confabulation?
Anterior communicating artery aneurysms (AcoA)
