CD4 and AIDS: Despite earlier reports of severe immunosuppression at baseline as an additional risk factor for impairment (Ellis et al., 2011), a relationship between the group’s lowest CD4+ counts (nadir/baseline CD4+) and RAFT performance was not forthcoming, suggesting that QDG-identified bradykinesia is related to immune changes in the later and controlled stages of HIV in those aging with the disease (Hunt, 2014), rather than the motor deficits observed in early, unmanaged stages (American Academy of Neurology AIDS Task Force, 1991).
