Tinnitus Management 2014: Part One

Fagelson (2014) reports that tinnitus affects some 10 to 15 percent of the population. He reports that there is no relationship between the distress/severity of the perceived tinnitus and auditory sensitivity and indeed, some 50 percent (or more) of tinnitus sufferers have a comorbid psychological injury or illness such as post-traumatic stress disorder (PTST), depression, anxiety, obsessive compulsive disorder, stress, and more.

BiCROS in Noise

Oeding and Valente (2013) examined the performance of a bilateral contralateral routing of signal (BiCROS) hearing aid in noise while engaging the receiver and transmitter noise reduction (NR) technology within Unitron’s Tandem 16 (16 channel) BiCROS hearing aid. The authors report that there are few peer-reviewed studies in which the efficacy and effectiveness of BiCROS technology has been examined in background noise. Twenty-one adults experienced with BiCROS participated in the study.

Parkinson's Disease: Update 2008

Parkinson's Disease (PD) is referred to as a motor system disorder resulting from loss of dopamine-producing brain cells. PD usually impacts people over age 50, but can sometimes affect younger people as well. Diagnosis of PD is based on clinical signs and symptoms, there are no objective tests (blood tests, radiographic studies, etc.) of PD. The four primary symptoms of PD include:


  1. Tremor/trembling in hands, arms, legs, jaw, and face.
  2. Rigidity, or stiffness of the limbs and trunk.

Sudden Sensorineural Hearing Loss—Treatment Status

Dallan, De Vito, and colleagues (2010) re-stated the previously declared nature of sudden sensorineural hearing loss (SSNHL) as a true audiological emergency. However, they state that the natural history of SSNHL is currently unknown (i.e., how often does it occur, how much will resolve if untreated, what are the natural outcomes if untreated, which treatments have a scientific basis, what are the outcomes of the scientifically proven treatments, etc.). Dallan, De Vito, and colleagues report that the unknowns are important factors in understanding and evaluating treatments.

fMRI 2008: Review and Update

Functional Magnetic Resonance Imaging (fMRI) is less than 20 years old, yet has provided unique insight into auditory, language, and cognitive processing. fMRI is non-invasive and measures hemodynamic (blood flow and circulation) changes associated with enhanced neural activity (Logothetis, 2008).In essence, the fMRI compares brain activity with and without specific stimulation.

The American Academy of Neurology & Neurology (the journal) Offer Evidence-Based Analysis of BPPV Treatment

T.D. Fife MD (Barrow Neurological Institute and the University of Arizona College of Medicine) and colleagues* authored a new article titled "Practice Parameter: Therapies for Benign Paroxysmal Positional Vertigo (BPPV) - An Evidence Based Review" in the journal Neurology (May 27, 2008). The authors review and analysis is based on 925 articles published between 1966 and 2006. Fife et al define BPPV as having brief recurrent episodes of vertigo triggered by changes in head position with respect to gravity. They note BPPV is the most common cause of recurrent vertigo.

Motor Cortex-Machine Interface: Monkey Controls Prosthetic Using Brain Activity

As reported in Nature (May 2008), researchers Velliste, Pwerel, Spalding, Whitford, and Schwartz reported their success with two rhesus monkeys to achieve "multi-degree-of-freedom" control over a prosthetic/robotic arm to achieve self-feeding. Previously, scientists and researchers have reported devices controlled by remaining nerves from arms and legs to control artificial limbs. In the new report, control is initiated directly from the brain.
