Why is HIV in Africa so Severe?

Type D HIV is a type of AIDS, and US scientists have found that certain types of HIV are more likely to cause cognitive impairment in patients. A study by Johns Hopkins University in the United States showed that patients infected with a special subtype, the D-type AIDS virus, are more likely to develop dementia than other subtypes of AIDS.

Type D HIV

This finding proves for the first time that certain types of HIV are more likely to cause cognitive impairment in patients. Related research results were published in the September 2009 issue of Clinical Infectious Diseases.

Sachter noted that the difference in the rates of dementia between these two subtypes is so surprising. If this is the case in sub-Saharan Africa, HIV-related dementia is probably one of the most common dementias in the world, and it is still far from being recognized.

Research suggests that it is likely that some biological characteristics of various subtypes of HIV affect patients' chances of developing dementia. Researchers predict that type D HIV may cause more brain inflammation and damage. They are working hard on this.
