According to the World Health Organization (WHO), hundreds of millions of people worldwide are affected by neurological disorders. More than 6 million people die from stroke each year, and more than 80% of these occur in low- and middle-income countries.

Malnutrition directly or indirectly affects a variety of organ systems including the central nervous system such as protein-energy malnutrition, iodine deficiency, vitamin A deficiency and iron deficiency anemia.

Dementia includes a group of symptoms that affect your memory, thinking, and social abilities, and can impact your daily life. Although dementia generally involves memory loss, having memory loss alone does not mean you have dementia.

Adenovirus infection can cause a number of diseases such as upper and lower respiratory tract infections, gastrointestinal infections, neurological infections and eye infections. Severe cases of viral infections can lead to death.

HSV-1 and HSV-2 infect approximately two-thirds of the world's population regardless of sex, geography, or climate. The ubiquitous nature of this infection is due to lifelong host infection, asymptomatic infection of the oral or genital mucosa, and low morbidity and mortality. Close person-to-person oral or genital contact is necessary for HSV transmission because the virus enters through mucous membranes or epidermis.

Primary VZV infection causes chickenpox in children, a common disease before the vaccine became widely available in 1995. Because humans are the only reservoir of this highly contagious airborne virus, the incidence of chickenpox has declined since the vaccine became available.

“Twelve modifiable risk factors are responsible for about 40% of dementia cases worldwide, so it is theoretically possible to prevent or slow the progression of dementia,” the researchers say.

Central nervous system infections are caused by many agents, including bacteria, fungi, spirochetes, parasites, viruses... Patients can suffer from purulent meningitis, encephalitis, brain abscess... and have a high risk of death or increasing the burden of disease for the family and society.

Neurological infection is a dangerous complication after brain surgery, the most common is purulent meningitis. Treatment of intracranial infection mainly uses antibiotics. Postoperative intracranial infection needs to be detected and treated early, otherwise it will be life-threatening or leave neurological sequelae.

Neuroinfectious diseases include a range of diseases caused by viruses, bacteria, parasites or fungi that invade and affect the body's nervous system. Although advances in diagnosis and treatment have made it possible to detect neuroinfectious diseases early, they can still cause serious problems.
