Document Summary
Address how upper motor neuron lesions cause spasticity". Posterior association areas of parietal-temporal-occipital lobes and agnosia. Lesion posterior association areas of parietal-temporal-occipital lobes. Agnosia inability to recognize incoming information despite intact sensory capacity. Tactile agnosia (astereognosis) unable to recognize forms by handling; but tactile, proprioceptive, and thermal senses are fine (middle cerebral artery involvement) Perception is skewed and it will take longer for them to interact with the environment may be hard for the patient for verbalize or describe how they are feeling (may be hidden) Prosopagnosia: difficulty naming people on sight (posterior cerebral artery involvement) Difficulty may range from name finding to inability to recognize long-term companions. Memory immediate and short term deficits common (36% of strokes) Lots of different strategies needing to be implemented. Feeling out process of recovery vs underlying serious memory issue. Long term memory deficits less common, often intact. The posterior cerebral arteries (pcas) supplies the corresponding occipital lobe, medial and inferior temporal lobe.
