Herpes virus may cause cognitive impairment

Herpes virus can enter the brain and cause cognitive impairment

Scientists have discovered unexpected risks associated with colds on the lips. Blisters on the lips or face are uncomfortable, but many people with herpes simplex virus are used to the occasional rash.
American researchers have described the alarming consequences of HSV. The pathogen is able to bypass the body's protective barriers and penetrate the brain through the nasal cavity, causing inflammatory processes, anxiety and cognitive deterioration.

The experts carried out experiments on laboratory animals and found out that the virus spreads through the lacrimal fluid and quickly reaches the central nervous system. There, it activates a specific enzyme that increases inflammation and neuronal damage. As a result, rodents lost memory, coordination, and other cognitive functions. Interestingly, in experimental mice with inhibited activity of this enzyme, the inflammation was not as pronounced.

Previously, experts have found traces of herpesvirus in the brains of people with Alzheimer's disease, and statistics show that HSV carriers are twice as likely to experience dementia. A new study confirms that the virus is probably underestimated as a factor in the development of cognitive disorders. Scientists are considering the possibility of creating drugs that block a key enzyme to protect the brain from the devastating effects of infection.

Although the virus has not been eliminated, antiviral drugs can help heal skin lesions more quickly. Doctors may recommend topical ointments or prescribe tablets at the correct dose. It is important to start treatment as early as possible to reduce the risk of complications.
