Constant “sound” in the ears was called an early sign of brain disease

Parkinson's disease is a progressive condition in which the signals transmitted between the brain and the nervous system are disturbed. As a result, a number of disorders appear, most of which are related to the motor process. At first, the symptoms are subtle, but as the disease progresses, they become quite pronounced.

According to research, one of the earliest signs can be constant ringing in the ears. This condition is known as tinnitus.

“Tinnitus is considered a 'mild' sign of a neurodegenerative disease characterized by a progressive loss of neuronal function, for example, in Alzheimer's disease (AD) and Parkinson's disease (PD),” the scientists said. .

“The main findings of our study are that the risks of developing Parkinson's disease increased after patients were first diagnosed with tinnitus,” they added.

In the course of study analyzed health data of 12,657 patients with tinnitus and 25,314 patients from the control group. During the 10-year follow-up period, 398 people with tinnitus (3.1%) and 501 people without tinnitus (2%) developed Alzheimer's disease. An additional 211 tinnitus patients (1.7%) and 249 control patients (1%) developed Parkinson's disease.

In addition, several other potential independent risk factors for the two diseases were identified. In particular, diabetes and head injuries have been linked to Alzheimer's disease, while cerebrovascular diseases and osteoarthritis – to Parkinson's disease.
