Background and Aim: Hearing loss is one of the most prevalent chronic conditions affecting the elderly. The impacts of hearing loss are depression, social isolation, and functional disability, particularly for those who have not yet been evaluated or treated for hearing loss. The aim of this study was audiologic screening and assessing candidacy  for hearing aid in the elderly people.
Materials and Methods: This analytic-cross sectional study was performed on 52 older adults aged from 51 to 97. Subjects were evaluated according to ASHA guidelines for audiologic screening in adults (1997). Using HHIE-S as hearing disability screening instrument, the need for hearing aid use was evaluated.
Results: About 86 percent of subjects had some degree of hearing loss. There were significant correlation between PTA(0.5, 1, 2) KHz>26 and HHIE-S>10. According to these two factors 21.2 percent of subjects needed to use hearing aid while 18 percent of this group had hearing aids.
Conclusion: There is high prevalence of hearing loss among older adults, thus it&aposs necessary to evaluate the need for hearing aid in this rapidly growing population. Among different factors affecting hearing aid candidacy the most correlated were PTA(0.5, 1, 2)KHz>26 and HHIE-S>10. Therefore according to this study by combination of these two evaluation of hearing aid candidacy would be more appropriate.

Background and Aim: Patients with Parkinson&aposs disease manifest oculomotor abnormalities. This is the consequence of basal ganglia impairment.  The most common abnormalities include increased saccade latency, hypometric saccades  and decreased saccade velocity. The purpose of this study was comparison of saccadic parameters using videonystagmography in patients with idiopathic Parkinson&aposs disease and normal subjects.
Materials and Methods: In this cross sectional study, saccadic movements were investigated in thirty patients with idiopathic Parkinson&aposs disease and thirty age matched subjects were 35-70 years old. Saccade latency, velocity and accuracy were quantitatively analyzed.
Results: Results of this study indicated increased saccade latency, reduction of saccade velocity and accuracy in patients with Parkinson&aposs disease(P<0.001).
Conclusion: This study showed that patients with Parkinson&aposs disease manifest saccadic deficits. This suggests dopaminergic control of these ocular movements.

Background and Aim: Memory is one of the aspects of cognitive function which is widely affected among aged people. Since aging has different effects on different memorial systems and little studies have investigated auditory-verbal memory function in older adults using dichotic listening techniques, the purpose of this study was to evaluate the auditory-verbal memory function among old people using Persian version of dichotic auditory-verbal memory test. Methods: The Persian version of dichotic auditory-verbal memory test was administered to 23 old people ranging 60-80 years and 30 young people aging 20-30 years, with normal and symmetric hearing in both ears. The performance of the two groups was compared. Results: The mean score of young (6.36±0.43) and old (4.58±0.74) adults on dichotic auditory-verbal memory test were significantly difference (p=0.001). The correlation test showed a negative correlation between age and the memory scores in aged people (r=0.36). A significant difference in recall of early (p=0.034), middle (p=0.037), and final (p=0.041) words was seen between aged and young people. Conclusion: Based on the obtained results, significant reduction in auditory memory was seen in aged group and the Persian version of dichotic auditory-verbal memory test, like many other auditory verbal memory tests, showed the aging effects on auditory verbal memory performance.
