Although genetically variable, it is a normal concomitant of ageing and is distinct from hearing loss caused by noise exposure, toxins, or disease agents. [1] Common conditions that can increase the risk of hearing loss in elderly people are high blood pressure, diabetes, or the use of certain medications harmful to the ear.
Auditory processing disorder (APD), rarely known as King-Kopetzky syndrome, is a neurodevelopmental disorder affecting the way the brain processes sounds. [2] Individuals with APD usually have normal structure and function of the ear, but cannot process the information they hear in the same way as others do, which leads to difficulties in recognizing and interpreting sounds, especially the ...
Acoustic sources within the "jet pipe" also contribute to the noise, mainly at lower speeds, which include combustion noise, and sounds produced by interactions of a turbulent stream with fans, compressors, and turbine systems. [1] The jet mixing sound is created by the turbulent mixing of a jet with the ambient fluid, in most cases, air.
One consequence of the degenerative brain disorder is wandering, which can be dangerous—and sometimes deadly—for those struggling with short- and long-term memory loss.
Noise exposure is the cause of approximately half of all cases of hearing loss, causing some degree of problems in 5% of the population globally. [52] The majority of hearing loss is not due to age, but due to noise exposure. [53] Various governmental, industry and standards organizations set noise standards. [54]
Traumatic noise exposure can happen at work (e.g., loud machinery), at play (e.g., loud sporting events, concerts, recreational activities), and/or by accident (e.g., a backfiring engine.) Noise induced hearing loss is sometimes unilateral and typically causes patients to lose hearing around the frequency of the triggering sound trauma. [17]
Sundowning “typically occurs in the late afternoon and evening in individuals diagnosed with dementia,” says Shannel Kassis Elhelou, PsyD, a geropsychology and neuropsychology fellow at the ...
Lower brain oxygen levels caused by sleep apnea were linked to changes to the white matter, which could lead to cognitive problem, a new study suggests. Sleep apnea impacts brain in ways that may ...
