Introduction
If cerebral ischemia is mild, it may not lead to arteriosclerosis and tinnitus may not occur. However, if cerebral ischemia is severe, it may cause atherosclerosis, impair cerebral blood circulation, and subsequently result in abnormalities in brain regions responsible for analysis, sensory receptors, and sensory nerve fibers, leading to symptoms such as lip numbness, tinnitus, and head noise (brain murmurs).
Mild cerebral ischemia may not cause tinnitus. However, if the cerebral blood supply insufficiency is severe, tinnitus may occur. The detailed analysis is as follows:
1. May not occur
Cerebral hypoperfusion refers to reduced blood flow in the cerebral arteries below normal requirements. If the condition is mild, it may not lead to cerebral arteriosclerosis and therefore does not result in tinnitus. However, patients might still experience symptoms such as headache or dizziness.
2. May occur
If cerebral blood supply insufficiency is severe, it may lead to atherosclerosis, impairing cerebral blood circulation. This can subsequently cause abnormalities in brain processing regions, sensory receptors, and sensory nerve fibers, resulting in symptoms such as lip numbness, tinnitus, and head noise (brain murmurs).
When symptoms of cerebral hypoperfusion appear, it is recommended to seek timely medical attention at a hospital. Doctors will determine an appropriate treatment plan based on the severity of the condition. During treatment, patients should ensure adequate rest and maintain emotional stability, avoiding large mood fluctuations that could interfere with recovery.
