HIV and cognitive health: what the WHO says

I have been living with HIV, controlled with medication for years. I read that HIV can affect cognition in the long term. Is there anything different I should do to protect my brain?

Your question is well-informed, and the answer is, essentially, reassuring: if you have well-controlled HIV with therapy, you are already doing the most important thing for your brain.

Why this topic exists

Untreated HIV can affect the central nervous system, and before modern therapies, cognitive complications were common. With current treatments and sustained viral suppression, these severe complications have become rare — but research continues to study subtle long-term effects, especially in those who have lived with HIV for decades. This is why the topic appears in WHO guidelines.

What the guidelines say

Two things. First, the foundation: antiretroviral therapy should be initiated and maintained in all people with HIV, with the goal of viral suppression — this is unwavering. Second, specifically: to reduce the risk of cognitive decline, there is not enough evidence to prefer one therapeutic combination over another — the regimen should be chosen based on disease control and patient preferences, as is already standard practice. In other words: there is no proven "neuroprotective regimen" to ask your doctor for.

What you can do — the same as everyone else, with a note

The prevention strategies with the best evidence apply to you exactly as they do to the general population: physical activity, not smoking, moderate alcohol consumption, a balanced diet, an active social life, and control of blood pressure, sugar, and cholesterol. The specific note: some people who have lived with HIV for many years have an increased cardiovascular risk — which makes monitoring these factors even more valuable in your case. Discuss this during your routine appointments.

If you notice changes

Persistent forgetfulness or difficulty concentrating should be mentioned to your doctor — not out of alarm, but because they have many possible causes (sleep, depression, medication, thyroid) and most are treatable. With a suppressed viral load, the probability of it being "due to HIV" is low.
