A neurocognitive disorder attributable to documented HIV infection, with cognitive decline not better explained by non-HIV conditions, including HIV-associated opportunistic infections or malignancies affecting the central nervous system.
Some individuals with HIV infection develop cognitive impairment directly attributable to the virus's effects on the central nervous system, ranging from mild to severe. This diagnosis requires documented HIV infection and evidence that the cognitive decline is not better explained by another cause, such as an opportunistic infection, a central nervous system malignancy, or a co-occurring substance use disorder.
Risk and severity are related to the stage and management of HIV infection; effective antiretroviral treatment has substantially reduced the incidence of more severe presentations.
Cognitive symptoms can range from mild difficulties with attention and processing speed to more significant impairment affecting daily functioning, depending on severity.
Motor slowing and mood symptoms can accompany the cognitive changes; adherence to antiretroviral treatment is an important factor in both prevention and management.
Stigma surrounding HIV status can affect willingness to disclose diagnosis or seek evaluation for cognitive symptoms, making a sensitive, non-judgmental clinical approach essential.
A common misconception is that cognitive decline in someone with HIV is always attributable to the virus itself; opportunistic infections, malignancies, substance use, and other causes must be actively ruled out first.
Reconsider this diagnosis if an opportunistic infection, malignancy, or other clearly identifiable cause is found to better explain the cognitive decline.
A 45-year-old man with a well-documented HIV diagnosis, engaged in ongoing antiretroviral treatment, develops gradual difficulty with attention and processing speed, with a full medical workup ruling out opportunistic infection or malignancy as the cause.
Know
Know that documented HIV infection plus exclusion of other explanatory causes (opportunistic infection, malignancy, substance use) is required for this diagnosis.
Notice
Notice that treatment adherence and HIV disease stage are relevant contextual factors in both risk and management.
Distinguish
Distinguish from Substance/Medication-Induced Neurocognitive Disorder by ruling out a co-occurring substance-use explanation before attributing cognitive decline to HIV itself.
Recognize
Documented HIV infection with cognitive decline not better explained by an opportunistic infection, malignancy, or other identifiable cause affecting the central nervous system.
Distinguish
Distinguish from Substance/Medication-Induced Neurocognitive Disorder by ruling out a co-occurring substance-use explanation before attributing cognitive decline to HIV itself.
An HIV-associated opportunistic infection or central nervous system malignancy (these require their own separate identification and treatment, and must be ruled out as the primary cause before attributing cognitive decline to HIV itself), Substance/Medication-Induced Major or Mild Neurocognitive Disorder (co-occurring substance use is common and should be assessed as a possible contributing or alternative cause), Delirium (an acute, fluctuating disturbance of attention and awareness, distinct from this more stable neurocognitive pattern).
In an individual with HIV infection and any baseline cognitive impairment, an acute superimposed delirium can be mistaken for simple progression of HIV NCD, delaying identification and treatment of a reversible acute cause.
The general 'due to another medical condition' category is sometimes used as a default even when a specifically named etiology like HIV infection is actually responsible, when the named category should always take precedence.
In people with both HIV infection and a substance use history, cognitive decline is easily and incorrectly attributed entirely to one cause when both may be contributing.
Reason
Apply
Distinguish NCD Due to HIV Infection from Substance/Medication-Induced NCD when both HIV status and substance history are present.
