Some Audiological Aspects of Temporal Lobe Epilepsy

Dr. Frank Musiek
By Julia Bak, B.S. Speech, Language, and Hearing Department, University of Arizona, Tucson, AZ Though often under the audiology diagnostic radar, many patients with temporal lobe epilepsy (TLE) (or epilepsy in general) have central auditory processing deficits (CAPD) and related auditory problems (Ehrlé, et al., 2001). Temporal lobe epilepsy, itself, will seldom affect pure-tone thresholds but it can and does

Hearing Loss, Multiple Sclerosis and the Auditory Nerve

Dr. Frank Musiek
Frank Musiek, Ph.D.   Peripheral hearing loss is not commonly associated with multiple sclerosis (MS). Rather, MS is often associated with central auditory dysfunction not usually portrayed by pure tone hearing loss. However, sensorineural hearing loss (SNHL) associated with MS, reflected by pure tone threshold deficits does occur. Though not always the case, loss of hearing sensitivity in MS can

The Thalamo-cortical Pathway

Dr. Frank Musiek
Frank Musiek, Ph.D.   The term thalmo-cortical pathway (TCP) is an anatomical one and one of import to audiologists. However, it seems to be a term that is not commonly used in neuroanatomy or audiology. Therefore, consistent with Pathways articles, to focus on some lesser known but important topics, a brief account of the TCP is presented.    Some Neuroanatomy
