![]() ![]() The goal of this paper is to check the Auditory Processing of temporal lobe epilepsy patients, as to the mechanisms of: discrimination of sounds in sequence and of tonal patterns, discrimination of the sound source direction, and recognition of verbal and non-verbal sounds in dichotic hearing. Knowing that for a correct analysis and interpretation of the information received through one's hearing (auditory processing) it is necessary to have full anatomical and functional integrity of all these structures and that the electric discharges caused by the crisis may cause neuronal losses in the region where they occur, therefore it has been thought that there may be difficulties in the mental processing of the information received through hearing, and this could impair even further the communication skills of these patients. The auditory pathway ends at the temporal lobe (primary and secondary auditory cortex), after going through many central and peripheral structures of the auditory system. Data as to its occurrence vary between 50% of epileptic adults and 70 to 80% of teenagers with the disease 1. Temporal lobe epilepsy is the most common form of the disease, and the one most difficult to control. ![]() According to the WHO (1994), this disease affects from three to five individuals for 1000 of the world population, and in developing countries this figure may reach 15 to 50 for each 1000 inhabitants. Many are the causes for this disorder, such as: pre and post natal infections, traumas, parasitic infestations, intoxication, strokes, genetics, or even unknown causes 2. Individuals with temporal lobe epilepsy had more deficits in auditory processing than those without cortical damage.Įpilepsy is a set of clinical manifestations that may reflect a temporary neural dysfunction - abnormal and excessive electric discharges 1. Comparing the other auditory mechanisms assessed, the patients with temporal lobe epilepsy presented worse results. ![]() Similar performances were observed between patients with temporal lobe epilepsy and the control group regarding the auditory mechanism of sound source direction discrimination. Their performances were compared to the performances of individuals without neurological diseases (case-control study). ![]() The evaluation was carried out through special auditory tests: Sound Localization Test, Duration Pattern Test, Digits Dichotic Test and Non-Verbal Dichotic Test. MethodĮight individuals with temporal lobe epilepsy were assessed, after excluding those with non-confirmed diagnosis or with the focus of discharges not limited to this lobe. To check the Auditory Processing in patients with temporal lobe epilepsy regarding the auditory mechanisms of discrimination from sequential sounds and tone patterns, discrimination of the sound source direction and selective attention to verbal and nonverbal sounds. Both the anatomical and functional integrity of the auditory pathway structures are essential for the correct processing of auditory stimuli. Temporal epilepsy, one of the most common presentation of this pathology, causes excessive electrical discharges in the area where we have the final station of the auditory pathway. ![]()
