Background and Objectives: Dizziness and the accompanying complaints, including sleep disorders and depression, are common among the elderly. This study investigated the effect of vestibular rehabilitation on complaints of dizziness, sleep problems, and the severity of depression in older people with chronic dizziness. Subjects and Methods: The study included 25 participants with chronic dizziness accompanied by comorbid sleep disturbance (Pittsburgh Sleep Quality Index [PSQI] global score >5). Participants completed the Dizziness Handicap Inventory (three sub-scales: physical, emotional, and functional), the PSQI, and the Persian version of the shortened Beck Depression Inventory (BDI-13) before and after the vestibular rehabilitation. Results: The findings showed that the handicap caused by dizziness, the severity of depression, and the quality of sleep in the study participants improved significantly after the intervention (p<0.05). Conclusions Vestibular rehabilitation is an effective intervention to reduce dizziness handicap, comorbid sleep disturbance, and depression.

Understanding speech in the presence of noise is difficult and challenging, even for people with normal hearing. Accurate pitch perception, coding and decoding of temporal and intensity cues, and cognitive factors are involved in speech perception in noise (SPIN); disruption in any of these can be a barrier to SPIN. Because the physiological representations of sounds can be corrected by exercises, training methods for any impairment can be used to improve speech perception. This study describes the various types of bottom-up training methods: pitch training based on fundamental frequency (F0) and harmonics; spatial, temporal, and phoneme training; and top-down training methods, such as cognitive training of functional memory. This study also discusses music training that affects both bottom-up and top-down components and speech training in noise. Given the effectiveness of all these training methods, we recommend identifying the defects underlying SPIN disorders and selecting the best training approach.
