consequences of strokes
What are the sx of a posterior cerebral artery stroke
-visual problems- cortical blindness, visual agnosia, homonymous hemianopia
-thalamic syndrome
-declarative memory loss
what does the posterior cerebral artery supply
midbrain, occipital lobe, temporal lobe
what does the cerebellum specialize in
balance, high level ms movement, creative/intuitive, integration and coordination of movement, initiation and timing
What is the different between wernickes and brocas aphasia
wernickes- cant comprehend others, can speak a lot but doesn't make sense
brocas- can comprehend others, knows what they want to say but struggles saying it
what are common sx of frontal lobe stroke
contralateral weakness, perseveration, inattention, personality changes, impaired concentration, brooks aphasia, delayed/poor initiation, emotional lability
What are the symptoms of a vertebral/basilar artery stroke?
-sensory and motor losses (tetraplegia)
-reticular activating system (coma)
-cranial n signs
-locked-in syndrome
-disorders of motor coordination
-dysarthria
what do the verbal/basilar artery supply
brainstem and cerebellum
what is the function of the frontal lobe
voluntary movement, brooks area (L hemisphere), personality, judgement, temper, behavior
what are the common sx of a parietal lobe stroke
dominant hemisphere- agraphia, Alexia, agnosia
non-dominant hemisphere- dressing apraxia, anosognosia
contralateral sensory deficits, impaired language comprehension, impaired taste
what are the common sx of L CVA
R sided hemiplegia
R sided sensory loss
speech and language impairments
aphasias
difficulty processing verbal cues
slow, cautious, disorganized
difficulty expressing positive emotion
What are the symptoms of an anterior cerebral artery
-personality changes
-contralateral muscle weakness or paralysis (hemiplegia) of LEG, contralateral sensory loss of LEG
-LE > UE
-loss bowel/bladder control
-perseveration
what are the sx of a brainstem stroke
unstable vital signs, decreased consciousness, decreased ability to swallow, weakness or paralysis on BOTH sides of the body
what is the function of the parietal lobe
sensation of touch, vibration, receives info from other areas of the brain, provides meaning for objects, interprets language and words, spatial perceptions
what does the L hemisphere specialize in
language, sequence, understanding language, written and spoken language, analytical, controlled, logical, rational, math, positive emotion
what are the common sx of a R CVA
L sided hemiplegia/paresis
L sided sensory loss
visual perceptual deficits
disturbance of body image anybody scheme
difficulty processing visual cues
quick, impulsive, poor judgement
cant perceive emotions
cant express negative emotions
what are the sx of a middle cerebral artery stroke
-hemiplegia and contralateral sensory loss of upper limb and face
-homonymous hemianopsia
- UE>LE
-aphasias
-perceptual deficits (unilateral neglect, agnosia, depth perception)
What are lacunar strokes
stroke in small and deep arteries in the cerebral whit matter that branch from the middle cerebral artery
- associated with hypertension and diabetes
what is the function of the occipital lobe
processing center for vial info, colors, light, shapes, judgement of distance
What does the R hemisphere specialize in
nonverbal processing, process info in holistic manner, artistic abilities, hand-eye coordination, comprehension, spatial relations, kinesthetic awareness, music, nonverbal communication, negative emotion, body image
what are the common sx of a cerebellar stroke
decreased balance, ataxia, decreased coordination, nausea, decreased postural alignment, nystagmus
What is the difference if the non-dominant or dominant hemisphere is involved in a meddle cerebral artery stroke?
dominant- language impairment (aphasia)
non-dominant- spatial relations, neglect, impaired non-verbal communication
What are the RED FLAGS (5 D's)
dizziness, diplopia, dysarthria, dysphagia, drop attacks
what is the function of the temporal lobe
auditory processing and olfaction, wernickes area (L hemisphere), interpret others emotions
what is internal carotid artery syndrome
massive infarction in area can occur is collateral circulation from circle of willis is absent
symptoms: uncle herniation, coma, death
what are the common sx in an occipital lobe stroke
homonymous hemianopsia, impaired extra ocular ms movement, impaired color recognition, reading and writing impaired
