is frequent to find some initial hemiparesis that tends to disappear or at least decreases in severity
Term
hemiparesis
Definition
may affect the articulatory organs

-is manifested as a dysarthria, usually a spastic dysarthria
Term
hemiparesis

-in the extrasylvian motor type II
Definition
(aphasia of the supplememtary motor area)
-usually a right leg hemiparesis is found, associated with gait difficulties
Term
hemiparesis
Definition
patients with Wernicke aphasia and extrasylvian sensory aphasia usually do not present motor defects, but occasionally a mild motor defect is observed at the onset of the aphasia
Term
hemiparesis
Definition
patients with extrasylvian motor aphasia type I usually do not present hemiparesis, even though may present deficits in controlling the eye movements and defects in visual scanning
Term

-hyperkinesia
Term
dysarthria
(cerebellum)
Definition
ataxia
Term
extraocular motor palsies
Definition
brain damage involving the frontal eye field (broadman's area 8) will result in impairments in eye movements, particularly by verbal command. it is not unusual to find extraocular motor disturbances in extrasylvian motor aphasia (typeI)
Term
pseudobulbar palsy
Definition
is the paralysis hat results from bilateral upper motor neuron lesions of the pyramidal tract. it produces a paralysis very similar to that seen with bulbar palsy
Term
apraxia
Definition
frequently associated with aphasia
- about 40% of the aphasia patients presents an ideomotor apraxia.
-some types of aphasia have been interpreted as segmentary apraxias
Term
apraxia
Definition
-conduction aphasia is associated with ideomotor apraxia
-in wernicke aphasia, finding ideomotor apraxia suggests an extension of the damage to the parietal lobe
-patients with broca aphasia may present a sympathetic apraxia
Term
apraxia of speech
Definition
-represents a disorder due to an impairment in planning and programming the sequences of movements required for speech production
-it is considered with agrammatism, one of the elements underlying broca aphasia
Term
apraxia of speech
Definition
-characterized by abnormalities in phoneme production (phonetic deviations), omissions, and substitutions of speech sounds.
-speech rate is decreased.
-language is not fluent and produced with effort
-errors are inconsistent
-automatic language is notoriously better produced
-it can be associated with oral apraxia (bucofacial) and/or dysarthria
Term
verbal apraxia
Definition
2 types:
-pre-rolandic and retro-rolandic
-the first one would correspond to "apraxia of speech
Term
verbal apraxia
Definition
apraxia of speech(frontal): kinetic apraxia and is associated with Broca aphasia.
-post-rolandic type is associated with conduction aphasia
Term
verbal apraxia
Definition
it has been suggested that verbal apraxia and conduction aphasia are the same disorder.
-that is; conduction aphasia in a verbal apraxia
Term
sensory disorders
Definition
1- somatosnsory defects
2- visual field defects
Term
somatosensory defects
Definition
are more evident in conduction aphasia, but they can also be found in a lesser degree in Broca and Wernicke aphasia, depending upon the extension of the lesion
Term
somatosensory defects
Definition
in conduction aphasia is not unusual to find hypoesthesia, difficulties in two-point discrimination and tactile extinction
Term
somatosensory defects

-visual field defects
Definition
-right homonymous hemianopia is almost invariable in alexia without agraphia
-in wernicke aphasia occasionally a right superior quadrantopsia is found
-extrasylvian sensory aphasia; occasionally some visual field defects may be found
-in parietal aphasia an inferior quadrantopsia can be found if damage extends deep into the brain
Term
disorders of cognitive function
Definition
-amnesia
-agnosia
-acalculia
-Gerstmann syndrome
-dementia
Term
amnesia
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
Term
agnosia
Definition
1- visual agnosia
2-auditory agnosia
3-somatic agnosia
Term
visual agnosia
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
visual agnosia
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
auditory agnosia
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
auditory agnosia
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
somatic agnosia
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
acalculia

(anarithmetia)
Definition
-not easy to find pure cases without associated aphasic defects
-usually, it has been assumed that lef posterior parietal damage is associated with primary _______________

-conduction aphasia is the type of aphasia most frequently associated

Term
acalculia

secondary
Definition
-agraphic acalculia
-frontal acaculia
-spatial acalculia
Term
aphasic acalculia
Definition
-calculation difficulties can be observed in aphasia, correlated with the language defects

-wernicke aphasia patients with verbal memory defects, will manifest these defects when performing arithmetical operations and solving numerical problems
Term
aphasic acalculia
Definition
-broca aphasia patients will present difficulties in using the syntax applied to the numerical problems and arithmetical operations

- in conduction aphasia, language repetition defects will be observed when repeating inverse numerical sequences
Term
alexic acalculia
Definition
-calculation defects can be correlated with reading difficulties. This is an alexic acalculia or alexia for numbers

-alexia with agraphia, alexia without agraphia, frontal alexia
Term
frontal acalculia
Definition
-patients can count, to compare quantities, and to perform simple arithmetical operations, especially if they can use pencil and paper. they present difficulties in mental operations, successive operation and solving arithmetical problems.
-it canbe found in extraslyvian motor aphasia type I
Term
Gerstmann's Syndrome
Definition
-acalculia
-finger agnosia
-right-left disorientation
-agraphia

-also referred to as angular gyrus syndrome
Term
Gerstmann's Syndrome
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
Gerstmann's Syndrome
Definition
-it has been proposed to replace agraphia by semantic aphasia; or simply to consider semantic aphasia as the 5th characteristic of syndrome
Term
Gerstmann's Syndrome
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
Term
disorders of cognitive function;

-dementia
Definition
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
vascular dementia
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
vascular dementia
Definition
aphasia can be found associated with other cognitive disturbances
Term
dementia
Definition
language disturbances can be found in different types of dementia such as:
1-frontal-temporal dementia
2-traumatic dementia
3-pick's disease
4-dementia due to infections of the brain
5-subcortical dementia (parkinson's disease)
Term
dementia
Definition
progressive aphasia can be found in a particular subtype of alzheimers disease
