Term
|
Definition
present difficulties to memorize verbal information. -a sub-type of wernicke aphasia has been interpreted as a specific verbal amnesia (anterograde and retrograde)
-in aphasia if damage extends to other areas, (prefrontal areas, hippocampus,), a broader amnesia can be found |

Definition
can be associated with aphasia
-semantic agnosia; mild moderate agnosic disorders re frequent. semantic anomia implies some difficulties in revisualization (representing for oneself) of the objects. |
|
|
Term
|
Definition
-can be associated with alexia
-alexia without agraphia (also called agnosic alexia) is always associated with visual agnosia. -alexia without agraphia can even be interpreted as a particular type of visual agnosia. it can be also associated with achromatopsia or achromatognosia |
|
|
Term
|
Definition
a specific type of aphasia that has been interpreted as a verbal auditory agnosia (word deafness, acoustic-agnosia aphasia, Wernicke aphasia type I) |
|
|
Term
|
Definition
-word deafness refers to inability for the phonological recognition of language. in acoustic-agnosic aphasia there are some difficulties in the recognition of the language sounds, associated with other aphasic phenomena, such as paraphasias |
|
|
Term
|
Definition
-finger agnosia, right-left disorientation, acalculia and agraphia are included in the so-called GERSTMANN SYNDROME -finger agnosia, autotopagnosia and even right-left disorientation can be interpreted as specific types of anomia (anomia for body lateral dimensions) |

|
|
Term
|
Definition
-aphasia is not supposed in "pure" cases -possible association with semantic aphasia (extrasylvian sensory aphasia type II) usually not considered -agraphia would correspond to an apraxic agraphia (non-aphasic), not necessarily associated with alexia |
|
|
Term
|
Definition
-it has been proposed to replace agraphia by semantic aphasia; or simply to consider semantic aphasia as the 5th characteristic of syndrome |
|
|
Term
|
Definition
or angular gyrus syndrome
-would include acalculia -finger agnosia (or a more extended form of autotopagnosia) -right-left disorientation -semantic aphasia
-sometimes agraphia without alexia is observed, but agraphia would be the consequence of the extension of the lesion toward the inferior parietal lobe |

a progressive decline in cognition due to damage or disease in the brain (degenerative condition, multiple brain infarcts,etc) beyond what might be expected from normal aging. particularly affected areas may be memory, attention, language and executive functions |
|
|
Term
disorders of cognitive function;
-dementia |
|
Definition
the language impairment found in Alzheimer's Disease has been equated with an anomia(initially), with an extrasylvian sensory aphasia (later), and with a mutism or semi-mutism in the terminal stages |
|
|
Term
|
Definition
second most common form of dementia. -vascular disease produces either focal or diffuse effects on the brain and causes cognitive decline. focal cerebrovascular disease occurs secondary to thrombotic or embolic vascular occlusions. the 3 most common mechanisms of vascular dementia are multiple cortical infarcts, a strategic single infarct, and small vessel disease. in multi-infarct dementia, the combined effects of different infarcts produce cognitive decline |

Term
|
Definition
aphasia can be found associated with other cognitive disturbances |
