Excessive salt consumption can have a negative effect on blood flow to the brain. According to a recent US study. In the worst case, this can lead to massive brain damage – and permanently.

New US study: Too much salt can cause serious brain damage

The researchers from the University of Georgia examined the influence of salt on the blood flow in the brain and the neurons. The focus was on a specific region in the brain, the hypothalamus. The study found that salt actually slows blood flow to the brain. What the team calls “inverse neurovascular coupling” could lead to hypoxia. Hypoxia (hypoxemia) is a reduced oxygen content in the blood or a lack of oxygen. According to netdoktor.de, irreparable brain damage can occur in such cases.

The researchers establish the connection to salt through a compensation mechanism in the body as soon as salt is consumed. In order to lower sodium levels, the body activates neurons that release the hormone vasopressin. In order for the neurons to be able to operate the salt stimulation for a long time, hypoxia is assumed to be an auxiliary mechanism. According to the researchers, in order to “fight” the salt, the body puts itself into hypoxia.

The approach of the study could be used for future insights into other brain diseases. Until then, it would be advisable for many people to save on salt. In addition to brain diseases, there are other symptoms that can occur with excessive salt consumption.
