Susac syndrome is a rare condition characterised by the clinical triad of encephalopathy, branch retinal artery occlusion, and sensorineural hearing loss. Of the few published cases, there is variability with regard to cognitive outcome. We describe the clinical course and neuropsychological performance of a 21-year-old male patient presenting with severe encephalopathy and later developing the full triad fulfilling the diagnosis of Susac syndrome.

Rhett S Thomson, Priscilla Auduong, Alexander T Miller, Richard K Gurgel
OBJECTIVES: To review evidence of hearing loss as a risk factor for dementia. Data Sources: PubMed Review methods: A systematic review was conducted using the PubMed database using the search terms (hearing loss OR presbycusis) AND (dementia OR cognitive decline). Initially, 488 articles were obtained. Only those studies evaluating an association between hearing loss and incident dementia or cognitive decline were included in the analysis. This resulted in 17 articles which were thoroughly evaluated with consideration for study design, method for determining hearing loss and cognitive status, relevant covariates and confounding factors, and key findings...

For people with hearing difficulties, following a conversation in a noisy environment requires substantial cognitive processing, which is often perceived as effortful. Recent studies with normal hearing (NH) listeners showed that the pupil dilation response, a measure of cognitive processing load, is affected by 'attention related' processes. How these processes affect the pupil dilation response for hearing impaired (HI) listeners remains unknown. Therefore, the current study investigated the effect of auditory attention on various pupil response parameters for 15 NH adults (median age 51 yrs...

Previous studies have demonstrated that successful listening with advanced signal processing in digital hearing aids is associated with individual cognitive capacity, particularly working memory capacity (WMC). This study aimed to examine the relationship between cognitive abilities (cognitive processing speed and WMC) and individual listeners' responses to digital signal processing settings in adverse listening conditions. A total of 194 native Swedish speakers (83 women and 111 men), aged 33-80 years (mean = 60...

BACKGROUND: Accumulation of problems in physical, psychological, cognitive, or social functioning is characteristic for frail individuals. Using a four-domain approach of frailty, this study explored how sociodemographic and lifestyle factors, life events and health are associated with frailty. METHODS: The study sample included 4019 men and women (aged 40-81 years) examined during the fifth round (2008-2012) of the Doetinchem Cohort Study. Four domains of frailty were considered: physical (≥4 of 8 criteria: unintentional weight loss, exhaustion, strength, perceived health, walking, balance, hearing and vision impairments), psychological (2 criteria: depressive symptoms, mental health), cognitive (<10th percentile on global cognitive functioning), and social frailty (≥2 of 3 criteria: loneliness, social support, social participation)...

OBJECTIVES: Studies in cognitive aging demonstrated inconsistent association between hearing and cognition in older adults. Furthermore, it is still unclear if hearing loss at high frequencies, which is the earliest to be affected, is associated with cognitive functioning. This study aimed to determine the association between global cognitive status and pure tone average (PTA) at 0.5, 1, and 2 kHz (PTA low) and PTA at 4 and 8 kHz (PTA high). METHODS: This study involved 307 adults aged 60 years and older...
