Symptoms Flashcards
Blindsight
Location damage – occipital lobe -> visual cortex
Symptoms –
* not consciously seeing visual stimuli, but having appropriate behavioral and physiological responses
Prosopagnosia
Location damage – occipital-temporal junction
Symptoms –
* inability to recognize the faces of familiar people
Split-Brain
Location damage – corpus callosum
Symptoms –
* when the left visual field is shown a spoon, the person can locate the spoon with their left hand, but cannot identify the object.
* when the right visual is shown a spoon, the person can locate the spoon with their right hand and identify the object.
Syndromes –
* the corpus callosum is severed in patients with seizures in an effort to stop/reduce seizures
Open Injury TBI
Location damage – varies
Symptoms –
* a penetrative injury to the brain resulting from a TBI
Closed Injury TBI
Location damage – varies
Symptoms –
* an internal injury to the brain resulting from a TBI
loss or alteration of consciousness that varies in severity
* when consciousness returns, a combination of emotional, cognitive, behavioral, & physical symptoms can occur
Cognitive Symptoms TBI
Location damage – varies
Symptoms –
* associated with closed TBI injuries
* anterograde amnesia; used to determine TBI severity & good predictor of recovery from other symptoms
* retrograde amnesia; recent long-term memory more effected, when memories return, distant past memories are recovered first
Post-Traumatic Epilepsy
(PTE)
Location damage – varies
Symptoms –
* occurs more than week after a TBI, more difficult to treat than PTS
* when medication is ineffective, vagus nervous stimulation, responsive neurostimulation, or surgery are explored
Syndrome –
* TBI
Post-Traumatic Seizures
(PTS)
Location damage – varies
Symptoms –
* occurs within one week after a TBI
* treated with anti-seizure medication
Syndrome –
* TBI
Ataxia
Location damage – cerebellum
Symptoms –
* impaired balance, coordination, lack of muscle control
* slurred speech
* blurred or double-vision, jerky eye movements
Achromatopsia
Location damage – occipital lobe -> visual cortex
Symptoms –
* loss of color vision
Syndromes –
* visual agnosia
Anomia
Location damage – frontal lobe -> Broca’s area + temporal lobe -> Wernicke’s area
Symptoms –
* inability to recall names of familiar objects or known words
Syndromes –
* Broca’s aphasia (expressive aphasia)
* Wernicke’s aphasia (receptive aphasia)
Agnosia
Location damage – varies
Symptoms –
* inability to interpret sensations
* inability to recognize things
Aphasia
Location damage – varies
Symptoms –
* inability to understand or express speech
Syndromes –
* TBI
* Broca’s area
* Wernicke’s area
Agraphia
Location damage – parietal lobe left hemisphere
Symptoms –
* impaired writing skills
Syndromes –
* Gerstmann’s
Acalculia
Location damage – parietal lobe left hemisphere
Symptoms –
* loss of math skills
Syndromes –
* Gerstmann’s
