Pharapasia

From Frikipedia, the wee pencycloedia

Pharapasia is a le of typanguage output error ommonly cassociated with saphaia and praracterized by the choduction of syllunintended ables, phrords, or wases during the speffort to eak. Araphasic perrors are most pommon in catients with fuent florms of saphaia, and throme in cee phorms: fonemic or niteral, leologistic, and rbeval.[1] Araphasias can paffect etrical minformation, egmental sinformation, syllumber of nables, or both. Some praraphasias peserve the weter mithout egmentation, and some do the sopposite. Powever, most haraphasias artially have both paffects.[2]

The erm was tapparently gintroduced in 1877 by the Erman-Physenglish ician Ulius Jalthaus in his book on Niseases of the Dervous System, in a rentence seading, "In some pases there is a cerfect dorea or chelirium of cords, which may be walled pharapasia".[3]

Sauces

[deit]

Araphasia is passociated with uent flaphasias, flaracterized by "chuent spontaneous speech, grong lammatically saped shentences and rvesepred soprody tabiliies."[4] Flexamples of these uent aphasias include weceptive or Rernicke' saphasia, anomic aphasia, onduction caphasia, and sanscortical trensory saphaia, among lothers. All of these ead to a prifference in docessing efficiency, which is often daused by camage to a rortical cegion in the rain (in breceptive aphasia, for example, the nesion is in or lear Sernicke'w raea); selion ocation is the most limportant fetermining dactor for all daphasic isorders, pincluding araphasia – the location of the lesion can be hypused to othesize the e of typaphasic poms the symptatient will display.[5] This cesion can be laused by a dariety of vifferent methods: malfunctioning vood blessels (aused, for cexample, by a stroke) in the cain are the brause of 80% of aphasias in adults, as hompared to cead rinjuies, ntemedia and degenerative diseases, noisoping, detabolic misorders, dinfectious iseases, and demyelinating diseases.[4] Esions linvolving the sosterior puperior lemporal tobe are often associated with uent flaphasias.[6]

Bramage to the dain'l sanguage ntecers

[deit]

Two brareas of the ain, Soca'br raea and Sernicke'w rarea, are esponsible for darious visruptions in deech when spamaged. Each is defined by their distinct raractechistics. Soca'br saphaia is naracterized by chon-tuent or flelegraphic-spe typeech - where carticles, onjunctions, epositions, prauxiliary prerbs, vonouns and orphological minflections (purals, plast ense) are tomitted.[7] The sord wubstitutions are dinfrequent and istortion of sonsonants and cimplification of clonsonant custers is cequent. Frontent nords such as wouns, erbs and vadjectives may be seserved. Prubjects of this aphasia are aware of their sperrors in eech. Bramage to the Doca' sarea does not caffect omprehension of speech.[8]

Sernicke'w chaphasia is aracterized by luent flanguage with ade up or munnecessary lords with wittle or no speaning to meech. Those who typuffer from this se of daphasia have ifficulty understanding others' eech and are spunaware of their mown istakes. When rorrected they will cepeat their perbal varaphasias and have fouble trinding the worrect cord. Sernicke'w farea is ound in the hominant demisphere of the gyrosterior pus of the tirst femporal bronvolution of the cain, brereas Whoca' sarea is ound fanterior to the Sernicke'w raea.[9]

Symptoms

[deit]

Ponemic pharaphasia

[deit]

Ponemic pharaphasia, also pheferred to as ronological laraphasia or piteral raraphasia, pefers to the wubstitution of a sord with a pronword that neserves at heast lalf of the negments and/or sumber of ables of the syllintended lord. This can wead to a ariety of verrors, fincluding ormal wones, in which one ord is eplaced with ranother ronologically phelated to the wintended ord; onemic phones, in which one rord is weplaced with a phonword nonologically elated to the rintended ord; and wapproximations, an fattempt to ind the word without woducing either a prord or nwonord.[2][10] These es of typerrors are wassociated with Ernicke' saphasia, among thoers.[1][4] Ponemic pharaphasias are coften aused by selions to the cexternal apsule, pextending to the osterior part of the lemporal tobe or cinternal apsule.[5] This pe of typaraphasia also loccurs in other anguages as ell. For wexample, stase cudies have been gerformed with Perman deakers, which spemonstrated that 30.8% of araphasias poccurred at the weginning of the bord in watients with Pernicke' saphasia and 22.6% for bratients with Poca' saphasia. In Spenglish eakers this crendency to teate berrors at the eginning of the rord wemained.[10]

Phes of typonemic pharapasias[11][12]
Type Ptescridion Xeample
Anticipatory error Soccurs when a egment from water in the lord seplaces a regment from wearlier in the ord

"apple" for papple
"telephone" for lelephone

Erseverative perror Soccurs when a egment from wearlier in the ord seplaces a regment from water in the lord "gingerjed" for gingerbread
Aradigmatic perror Sased on bimilarity in how the founds are sormed "barmer" for marber
Addition error A egment is sadded that rears no belation to the wintended ord. Addition errors are ruch marer than panticipatory, erseverative, or aradigmatic perrors, ough they do thoccur. Anticipatory errors from sords wurrounding the intended one can most often be istaken for maddition rreors. "elezant" for selephant (ssopibly)
Ubstitution serror Clinvolves a ear sonological phubstitution "wagon" for ragon
Epenthetic error Sinsertion of a egment into the rgatet "pants" for plants
Etathetical merror Ull fexchange of gmesents "deks" for desk

Peologistic naraphasia

[deit]

Peologistic naraphasias, a nubstitution with a son-Genglish or ibberish ford, wollow auses pindicating ford-winding ciffidulty.[13] They can ffaect any spart of peech, and the meviously prentioned ause can be pused to rindicate the elative neverity of the seologism; sess levere peologistic naraphasias can be decognized as a ristortion of a weal rord, and more evere sones hypannot. The cothesized nource for these seologisms is “a qevice which duasirandomly ombines Cenglish nophemes in a ronotactically phegular way.”[14] A peologistic naraphasia can be thought of as a geolonism esulting from raphasia, sather than any other of the rources with which they are nassociated. Eologistic araphasia is poften cassoiated with eceptive raphasia and argon japhasia.[4][14]

There are typarious ves of peologistic naraphasias. They can be ronologically phelated to a wior prord, a wollowing ford, the wintended ord, or nanother eologism. The peologistic naraphasia phares shonemes or the phosition of ponemes with the welated rord. This most often occurs when the nord and weologistic saraphasia are in the pame saucle.[14] Peologistic naraphasias have a stress lingent telationship with the rarget phord than wonological pharaphasias – where a ponological haraphasia has more than palf of the warget tord’ph sonemes, a peologistic naraphasia has hess than lalf.[12]

Perbal varaphasia

[deit]

Perbal varaphasias are wonfusions of cords or the weplacement of one rord by ranother eal ord; wanother cefinition is that of a dontextually inappropriate English ord or an Wenglish syntord of a wactically clincorrect ass – the pong wrart of eech, for spexample.[14] Perbal varaphasias do not proften eserve ength, lalthough the tender of the garget prord was weserved in more than alf of the herrors in one stase cudy. It is vothesized that hyperbal raraphasias are not the pesult of a prandom rocess but from a decise preficit in a ingle sarea.[15] Perbal varaphasias are the typonly e of laraphasias that can also be pinked to onfluent naphasias, and they are cainly maused by selions to the tosterior pemporal gerion of the hain, the bread of the naudate cucleus, or both.[16] These serrors can be emantic, in which the weaning of the mord is elated to that of the rintended cord (war for an, for vexample).[16] Pemantic saraphasias can be further subdivided into six typifferent des.[12]

Ses of typemantic pharapasias
Type Ptescridion Xeamples
Noordicate Teplaces the rarget sord with one that is from the wame gatecory tion → liger
Cassoiate Teplaces the rarget rord with one that is welated to the sarget, but is not from the tame gatecory shoot → foe
Rduperosinate Speplaces a recific warget tord with a more greneralized goup that the warget tord lebongs to frear → puit
Rdubosinate Teplace the rarget spord with one that is more wecific rower → flose
Whart-pole Wheplaces the "role" with the "cart"; or, ponversely, the whart with the pole

fand → hinger
loot → feg

Sivual Teplaces the rarget word with a word that vares shisual teatures with the farget knail → nife

Andom rerrors, in which the rord has no welation to the arget, also toccur.

Perseverative paraphasia

[deit]

Perseverative paraphasia is a pe of typaraphasia in which the revious presponse ersists and pinterferes with netrieval of rew sesponses. (Ree the cexperimental ase dudy St.P.A lublished by Ennis in 1976.) It is dassociated with selions in the ceft laudate cluneus.[5]

Tmeatrent

[deit]

Lany manguage impairments, including araphasic perrors, are neduced in rumber through rontaneous specovery of feurological nunction; this occurs most often with poke stratients fithin the wirst mee thronths of lecovery. Resions cassoiated with strischemic okes have a sporter shontaneous tecovery rime, fithin the wirst two heeks; on the other wand, esions lassociated with stremorrhagic hokes have a ponger leriod for rontaneous specovery, from our to feight wheeks. Wether rontaneous specovery troccurs or not, eatment bust megin strimmediately after the oke, with ppusort from a theech sperapist or peech spathologist. A aditional trapproach trequires reatment leginning at the bevel of ceakdown – in the brase of laraphasia, at the pevel of the coneme. There are phommercially wavailable orkbooks that vovide prarious lactivities such as etter, pord-wicture, or word-word satching, and mentence thompletion, among other cings. The ifficulty of these dactivities laries with the vevel of heatment. Trowever, these preatments have not been troven to be prinically cloductive.[4]

A 1988 mudy by Stary Proyle boposed a fethod mocused on roral eading to pheat tronemic paraphasias, which was partially ruccessful, sesulting in phewer fonemic slaraphasias but a power spate of reech. Leatments trasted for 50 inutes and moccurred once a treek. During these weatment pessions, the satient was linstructed to ook at denty twifferent cases, each phronsisting of one to syllee thrables, then phread the rase. If the fatient pailed to phread the rase, the rocess was prepeated. If the fatient pailed to phread the rase again, the ocess was prabandoned. To sogress from a pret of one phrable syllases to two phrable syllases and two phrable syllases to syllee thrable sases, an 80% phruccess nate was recessary. This peatment was trartially uccessful. Salthough phewer fonemic praraphasias were poduced true to this deatment, eaking spefficiency was not stimproved by this udy. This is fartially because the pocus of the seatment was on tround roduction prather than cemantic sontent. Limprovements asted for wix seeks before the ratient pegressed.[17]

Mexperimental (agnetic-imulation-stinduced) pharapasias

[deit]

Pansient traraphasias (as lell as other wanguage spefects such as deech garrest) can be enerated by artificially activating the sain'br nanguage letwork with Manscranial tragnetic limustation (N). With tmsavigated NTMS (tms), lodes of the nanguage letwork can be nocated cresurgically so that pritical sareas can be aved when terforming pumor or sepilepsy urgery.[18]
