Tinnitus – a manifestation of neurodegenerative diseases

Tinnitus is a widespread hearing impairment that can be characterized by the perception of sound, such as tone or noise, in the absence of an appropriate external sound source. The cause of tinnitus and mechanism are unclear. The prevalence of tinnitus is higher in people over 60 years of age. Tinnitus is usually a manifestation of а hear- ing impairment. Symptoms can be acute or chronic. In most cases, tinnitus manifests as an idiopathic condition. In the clinical practice, common factors that affect the psychological and emotional well-be-ing of people with tinnitus are: fear, stress, anxiety and depression, which in turn can cause insomnia, impaired concentration and cognitive dysfunction. Tinnitus is a heterogeneous disorder in terms of its etiology and clinic. Tinnitus is associated with hearing loss, as both symptoms often occur together, though in many clinical cases, people with hearing loss do not develop tinnitus. head injuries can be risk factors for AD and neurodegeneration. Conclusions Further research is needed to re-confirm the conclusions of our research and to investigate the pathophysiology of the relationship between tinnitus and the Alzheimer’s disease and tinnitus and the Parkinson’s disease in more depth.
