Até recentemente o rastreio auditivo baseava-se exclusivamente na avaliação dos Potenciais Evocados Auditivos do Tronco Cerebral (PEA), um método exigente em termos técnicos, demorado e que implica frequentemente uma sedação da criança. O advento das Otoemissões Acústicas (OEA), […]

Contribution of high click stimulus repetition rate in auditory evoked potentials in multiple sclerosis patients with normal mri
The purpose of this work was to evaluate if a stimulus reptition rate that is higher than 30 clicks/sec increases the sensitivity of the absolute latencies of waves I, III and V and interpeak intervals I-III, III-V and I-V in the Auditory Brainstem Responses.(ABR) of Multiple Sclerosis (MS) patients.
In patients with hypertrophic cardiomyopathy (HCM) coexisting sensorineural hearing disorders are present frequently. These disorders can be either cochlear or retrocochlear in origin. Our aim was to study the hearing function in patients with HCM and to compare this group with age matched controls . Our audiological investigations were performed in 44 patients with HCM. […]
At the Psychiatric Clinic of Szeged we began a comprehensive investigation with the aim of etiological sub-grouping of schizophrenia. As work hypothesis we treat schizophrenia as a progressive neurodevelopmental, multi-factorial long latency period disorder with notable genetic definiteness whose development and existence also significantly involves the influence of the environment. This disorder is heterogeneous clinically […]
The aim of the study was to observe the usefulness of Betaserc in therapy of vestibular disorders in the patients with vertebro-basilar insufficiency. 80 patients (43 female, 37 male) were tested on the base of videonystagmography, stabilometry and brain stem auditory evoked potentials. Betaserc was ordered in two separate doses: 3x 8mg and 3x 16 […]
The aim of this study was to elaborate an algorithm of the detection of brainstem lesion according BAEP changes. The following questions were raised for this purpose: 1) which interpretation strategy of BAEP changes selects the most patients with brainstem lesions? 2) which BAEP abnormalities differentiate between mass lesions of posterior fossa and demyelinating encephalomyelitis? […]
The tinnitus can be functionally measured and localized through sensorymotor and neurosensorial tests, then there arises a great demand for a systematic pharmacological treatment.
