Mohr–Tranebjærg syndrome (MTS) is a rare X-linked recessive syndrome also known as deafness–dystonia syndrome and caused by mutation in the TIMM8A gene. It is characterized by clinical manifestations commencing with early childhood onset hearing loss, followed by adolescent onset progressive dystonia or ataxia, visual impairment from early adulthood onwards and dementia from the 4th ...
Canine cognitive dysfunction (CCD) is a disease prevalent in dogs that exhibit symptoms of dementia or Alzheimer's disease shown in humans. [1] CCD creates pathological changes in the brain that slow the mental functioning of dogs resulting in loss of memory, motor function, and learned behaviors from training early in life.
Some strains of animals, such as white cats, have a tendency to congenital deafness. [1] Some known chemicals and elements can also affect deafness in animals. [2] Deafness can occur in almost any breed of cat or dog. This includes both pure-breed and mixed-breed animals, although there may be more prevalence in some specific breeds. [3]
The impact on life expectancy depends on the individual condition, [9] but is usually severe without treatment. [1] [3] It's estimated only 25–29% of people affected survive to adulthood, and only 10% to the age of 50. [1] The median life expectancy is around 9 years, and the average life expectancy is 16.3 years. [1]
Evidence is building that hearing loss may be the most impactful modifiable risk factor for dementia in mid-life, but the effectiveness of hearing aid use on reducing the risk of dementia in the ...
Deafness can occur in white cats with yellow, green or blue irises, although it is mostly likely in white cats with blue irises. [4] In white cats with one blue eye and one eye of a different color (odd-eyed cats), deafness is more likely to affect the ear on the blue-eyed side. [1] Approximately 50% of white cats have one or two blue eyes. [5]
Pendred syndrome; Other names: Goiter-deafness syndrome [1]: The normal cochlea has 2 & a half turns, but, in Pendred Syndrome, there is abnormal partitioning (the central bony core is reduced in size and complexity)and a reduced number of turns leading to a Mondini cochlea which has a basal turn and a dilated apical turn (1 & a half turns).
Its authors say the model is greater than 80% accurate and can predict disease up to nine years early. The study focused on all-cause dementia, as well as risk factors for Alzheimer’s disease ...
