THE ROLE OF RIGHT HEMISPHERE IN RECOVERY OF POST-STROKE APHASIA

, , , and

ABSTRACT

Previous data obtained especially from rTMS studies indicate that right hemisphere recruitment has a limiting effect on recovery of poststroke aphasia in right handed patients by inhibiting the activation of intact perilesional areas in left hemisphere and preventing them from regaining function. New researches bring new arguments to support the positive influence of right hemisphere on restoration of language and communication. In this paper we try to review the latest evidences regarding the contribution of the right hemisphere to post-stroke aphasia recovery.

BRAINSTEM AUDITORY EVOKED POTENTIALS IN PARKINSON’S DISEASE

, , , , , , , and

ABSTRACT

Background. Parkinson’s disease is a neurodegenerative disorder caused by loss of dopaminergic neurons in the substantia nigra, but also in other dopaminergic and nondopaminergic areas of the brain and mainly in the brainstem. Auditory evoked potentials are routinely used in clinical practice to evaluate the function of the auditory nerve and auditory pathways in the brainstem. The aim of this study was to investigate the auditory brainstem pathways in patients with Parkinson disease.

Materials and methods. In this study was included 34 patients with Parkinson’s disease. The control group was composed of 29 healthy age- and sex-matched subjects. Detailed examination were performed in all individuals and the parkinsonian patients were stage between 2 and 4 according to Hoehn and Yahr’s classication. Recordings of BAEPs were performed with Nihon Kohden Neuropack using 80 dB HL alternating polarity clicks in each ear at a rate of 10 s-1.. Averaged potentials to 1,000 clicks were obtained.

Results. The BAEP results were interpreted for the latencies of waves I, II, III, IV, V and Interpeak Latencies (IPL) I-III, III-V and I-V. The results of our study have shown that the waves II, III, IV, V and IPL III-V were significantly delayed bilaterally. This modifications does not correlates with the age or duration of disease

Conclusion. This study showed some modifications of auditory evoked potentials wich can be determined by the neurodegenerative process that affects the brainstem.
