Hellmuth’s area of expertise is HIV associated Neurocognitive Disorder, called HAND.
The diagnosis criteria for HAND was applied in identifying cognitive symptoms in long Covid patients.
Unexpectedly, 59 percent of the patients with cognitive symptoms met the HAND criteria compared with 70 percent of the control group.
Hellmuth explained: “Comparing cognitive performance to normative references may not identify true changes, particularly in those with a high pre-Covid baseline, who may have experienced a notable drop but still fall within normal limits.
“If people tell us they have new thinking and memory issues, I think we should believe them rather than require that they meet certain severity criteria.”
