export_aphasia Flashcards
Wernicke’s/Receptive Aphasia
Nonsensical Speech. Word salad. Unaware and unable to repeat
Brocas Area
Left Inferior frontal gyrus usually left side, muscles that control speech
wernickes area
broad region of left temporal and parietal lobes meaning of speach by recognizing spoken words. translate words into thoughts. the right side adds emotional content like anger or joy to spoken words
Broca’s/Expressive Aphasia
Can understand but have problem speaking. Understands having difficulty. Cannot repeat Usually ride sided weakness
Conduction Aphasia
-Arcuate Fasciculus
Abnormal Prosody
-Fluent, good understanding, repeat intact. W/o proper intonation -Right inferior frontal gyrus
Pure Word Deafness
- B/l damage to the posterior superior temporal lobes or disruption of connections between these areas. -Still able to hear sounds, speak, read, and write.
Akinetic Mutism
-Damage to cingulate gyrus bilaterally -This gyrus involved with emotions and regulation of aggressive behavior. Implicated in things like Schizophrenia/OCD
Transcortical Motor Aphasia
Broca’s but with repetition
Transcortical Sensory Aphasia
Like Wernicke’s but with repetition
Alexia without agraphia
damage to the L occipital specifically involving the splenium of the C callosum Information gets to only R side and cannot reach language areas on left
Aphasia
-Language problem -Neologism and paraphasic errors are common
Dysarthria
trouble w/ muscles of articulation
Dysphonia
Trouble w/ vocal cords.
Blood Supply to Language areas
MCA
Gerstmann’s Sydrome
-Lesion of dominant angular gyrus -Agraphia, Acalculia, Finger agnosia,L/R confusion
Apraxia
-Disorder of skilled movement not caused by weakness, akinesia, deafferentation, abnormal tone/posture, movement disorders such as tremors or chorea, intellectual deterioration, poor comprehension, or uncooperativeness
Neglect
Right parietal Lobe lesion
Prosopagnosia
Inability to recognize faces; Inferior temporal cortex
Astereoagnosia
-Parietal Lobe/primary somatosensory cortex - Inability to decipher objects from touch alone
Anton’s Syndrome
Denial of blindness due to damaged b/l occipital lobes.
Balint’s Syndrome
Damage to both posterior parietal lobes - optic ataxia (no coordination of hand/eye), oculomotor apraxia (inability to voluntarily guide eye movement), and simultagnosia (inability to percieve more than one object at a time in the visual field)
Posterior reversible encephalopathy syndrome
-Result of severe uncontrolled HTN particularly if there is rapid increase in blood pressure. Common with eclampsia Mostly occipital lobes but also maybe cerebellum. -Clinically: seizures, visual disturbances, headaches, and mental status changes.
Pseudo bulbar palsy
-Pseudobulbar palsy–tx w/ Dextromethorphan/quinidine _ tears for no apparent reason/ burst out laughing other times.
