Age-related hearing loss: prevention of threshold declines, cell loss and apoptosis in spiral ganglion neurons
Age-related hearing loss (ARHL) -presbycusis - is the most prevalent neurodegenerative disease and number one communication disorder of our aged population; and affects hundreds of millions of people worldwide. Its prevalence is close to that of cardiovascular disease and arthritis, and can be a precursor to dementia. The auditory perceptual dysfunction is well understood, but knowledge of the ...
متن کاملAltered cortical spectrotemporal processing with age-related hearing loss.
Presbycusis (age-related hearing loss) is a prevalent disability associated with aging that impairs spectrotemporal processing, but the mechanisms of such changes remain unclear. The goal of this study was to quantify cortical responses to frequency-modulated (FM) sweeps in a mouse model of presbycusis. Previous studies showed that cortical neurons in young mice are selective for the rate of fr...
متن کاملQuantification of Visual Field Loss in Age-Related Macular Degeneration
BACKGROUND An evaluation of standard automated perimetry (SAP) and short wavelength automated perimetry (SWAP) for the central 10-2 visual field test procedure in patients with age-related macular degeneration (AMD) is presented in order to determine methods of quantifying the central sensitivity loss in patients at various stages of AMD. METHODS 10-2 SAP and SWAP Humphrey visual fields and s...
متن کاملIctal cortical blindness with permanent visual loss.
Cortical blindness is rarely an ictal manifestation. We report the case of a man who developed transient cortical blindness followed by permanent visual deficits during repeated partial seizures. Intermittent visual impairment began at age 14 years. After he had the first generalized seizure at age 28 years, neurologic, ophthalmologic, angiographic, and brain computed tomographic (CT) examinati...
متن کاملVisual loss and visual hallucinations in patients with age-related macular degeneration (Charles Bonnet syndrome).
PURPOSE The condition in which visual hallucinations (VHs) are solely associated with a visual impairment is termed Charles Bonnet Syndrome (CBS). The study was undertaken to investigate whether the extent of visual acuity (VA) loss and central visual field loss predisposes a patient with age-related macular degeneration (AMD) to develop a CBS VH and, in addition, whether the progression in los...
