| Abstract | Mucanje je poremećaj tečnosti govora karakteriziran ponavljanjima, produživanjima, oklijevanjima, pauzama i/ili blokadama glasova, slogova i riječi koji može biti razvojnog ili stečenog porijekla. Njegovi simptomi mogu se odražavati kako na govornom, tako i na psihičkom, fiziološkom i socijalnom planu. Neurogeno mucanje, kao stečeni oblik mucanja, rjeđe je i manje poznato područje čije su netečnosti posljedica oštećenja mozga, najčešće posljedično moždanom udaru. Cilj ovog rada je, na temelju novije literature pružiti uvid u poznate etiološke čimbenike, simptomatologiju, diferencijalnu dijagnostiku te trenutne metode intervencije po pitanju neurogenog mucanja. Mehanizam nastanka nije u potpunosti razjašnjen ali brojni autori potvrđuju ulogu bazalnih ganglija kod pojave mucanja. Često koegzistira s poremećajima poput afazije i motoričkih govornih poremećaja kao što su dizartrija, apraksija i palilalija što dodatno otežava dijagnostiku. Osim teškoća prilikom diferencijalne dijagnostike uslijed prisustva drugih poremećaja postoje nesuglasice prilikom diferenciranja tipova mucanja, s obzirom na mišljenje da uočljivi simptomi nisu dovoljan distinktivni kriterij. U terapiji mucanja najčešće se primjenjuju bihevioralne metode, dok su lijekovi prisutni u manjoj mjeri zbog nuspojava i mogućnosti zloupotrebe. Da bi se pobliže objasnio navedeni poremećaj, potrebna su daljnja istraživanja. |
| Abstract (english) | Stuttering is a speech fluency disorder characterised by repetitions, prolongations, hesitations, pauses and/or blocks of phonemes, syllables and words. Considering its origin, stuttering can be developmental or acquired. Associated symptoms can be manifested not only in speech, but in physical, physiological and social status. Neurogenic stuttering is a lesser-known type of acquired stuttering predominantly caused by a stroke. The purpose of this review is to give an insight into given etiologic factors, symptomatology, differential diagnostics and therapeutic methods associated with neurogenic stuttering according to recent literature. The mechanism of incurrence is not entirely known, but the majority of contemporary authors implicate the role of basal ganglia system within such a mechanism. Neurogenic stuttering frequently coexists with aphasia and motoric speech impairments such as dysarthria, apraxia and palilalia, thus complicating the diagnostic process. Aside from these accompanying disorders, there are also numerous on-going dissidences in differentiating stuttering diagnoses, according to the opinion that observable symptoms are not the only distinctive characteristic of discrete stuttering categories. In terms of alleviating symptoms, behavioural therapy is the most common form of therapy used in response to a stuttering diagnosis while drugs are used less, largely due to the side effects of pharmaceutical medication, and the ever-present risk of misuse. At present, further research is required to accurately explain and approach to aforementioned disorder |
