Brief Communication: Frailty and Neurocognitive Impairment in Older People Living with HIV: A Cross-Sectional Study from Southeastern Brazil
This cross-sectional study of 128 older people living with HIV in Southeastern Brazil reveals that frailty and neurocognitive impairment are highly prevalent, with falls significantly associated with positive neurocognitive screening.

As medical treatments have improved, people living with HIV are now living much longer lives, often reaching ages where the body naturally begins to change. Just as anyone aging faces new health challenges, older adults with HIV are increasingly dealing with conditions like frailty and cognitive decline. Frailty is not simply being weak or tired; it is a specific state where the body loses its reserve, making a person more vulnerable to illness and injury. It often shows up as unintentional weight loss, exhaustion, or a noticeable slowing down. At the same time, the virus and the long-term effects of managing it can impact the brain, leading to difficulties with memory, thinking speed, and daily tasks. While doctors know these issues are common, they are often overlooked in routine care, especially in regions with fewer resources. Understanding how these two conditions appear together in older adults with HIV is crucial for helping them maintain their independence and quality of life.
In a recent study conducted in southeastern Brazil, researchers set out to examine exactly how often these conditions occur in older adults living with HIV and what factors might be linked to them. The team gathered 128 participants, all aged 50 or older, who were receiving treatment at a specialized infectious disease center. These individuals were not chosen at random from the general public but were patients already under medical care, most of whom had successfully suppressed the virus with medication. The researchers asked the participants about their daily lives, including their education, how many medications they took, and whether they had fallen recently. They also measured physical traits like body mass index and grip strength. To check for frailty, the team used a standard method that looks at five specific signs: losing weight without trying, feeling exhausted, having weak hand strength, walking slowly, and being less active. For the brain, they used a simple screening tool called the International HIV Dementia Scale, which tests memory and thinking skills. A score below a certain point on this test does not mean a person has dementia, but it does suggest they need further evaluation for possible cognitive issues.
The results painted a clear picture of a population that is aging with significant, yet often hidden, health burdens. Among the 128 people studied, the average age was nearly 60. While the vast majority had their virus under control, a large portion showed signs of physical decline. Only about 39 percent were considered robust and healthy. More than half were classified as "pre-frail," meaning they showed some warning signs but were not yet fully frail, and nearly 9 percent were already in the frail category. The study found that physical frailty was closely tied to body weight. People with a lower body mass index were significantly more likely to be frail, suggesting that maintaining muscle and weight is a critical factor in staying strong. The most common signs of frailty in this group were reduced muscle strength and a lack of physical activity.
When the researchers looked at the brain, the numbers were even more striking. More than half of the participants, 57.8 percent, scored low enough on the screening test to be flagged for possible neurocognitive impairment. This high rate was not random; it was strongly connected to specific life factors. People with fewer years of education were much more likely to screen positive, which researchers noted might be because the test relies on skills that are influenced by schooling, rather than just brain health. The study also found a clear link between taking many medications at once and having cognitive screening results that raised concerns. Perhaps most importantly, the researchers discovered a strong connection between falling and cognitive issues. Among those who screened positive for cognitive problems, nearly one-third had fallen in the last six months, compared to only 13 percent of those who did not screen positive. This suggests that a recent fall could be a useful warning sign for doctors to check a patient's thinking skills more closely.
The study did not prove that one condition causes the other, nor did it determine if the cognitive issues were permanent. Because the researchers looked at everyone at a single point in time, they could only show that these factors happened together. For instance, while there was a trend showing that people with cognitive screening issues were more likely to be frail, the numbers were too small to call this a definitive link. However, the findings reinforce a vital message: even when the virus is well-controlled, older adults with HIV are still at risk for the common problems of aging. The high rates of pre-frailty and positive cognitive screening indicate that routine medical visits for this group should include checks for physical strength and mental sharpness. By paying attention to simple signs like a recent fall, low body weight, or the number of pills a patient takes, healthcare providers might be able to spot these issues earlier and help patients stay active and independent for longer.
