“…Previous findings primarily from regions endemic for HTLV-1 suggest that HTLV-1 is associated with cognitive impairment and depression, consistent with associations between HTLV-1 and several types of neurological disease, including HAM/TSP [10,17,19]. Despite previous findings associating HTLV-1 with worse cognitive function and depression, however, our main findings in this community sample of adults in the UK are that there were no associations of HTLV-1 seropositivity and serointensity with performance on three cognitive tasks-reasoning, pairs-matching, and reaction time or depression.…”

“…This study found that while there were no differences in screening cognitive measures between groups, the combined overall HTLV-1 group had worse episodic memory and executive function, albeit with small effect sizes and worse fine-motor skills with large effect sizes compared to the control group. In addition, there were no differences in cognitive function between the HTLV-1 subgroups [17], findings suggesting that cognitive impairment in HTLV-1 can occur in the absence of HAM/TSP and in asymptomatic HTLV-1. In another study from Brazil [19], both asymptomatic HTLV-1 patients and HTLV-1 patients with HAM/TSP had worse cognitive function compared to healthy controls on some but not all of the assessed cognitive measures.…”

“…Considering the relatively high prevalence of cognitive deficits in neuroinfections (Levine et al, 2020) and their impact on daily living, it is paramount to investigate impairments caused by COVID-19. Although we must consider pulmonary or neurovascular damage, other mental disorders, and psychosocial factors (Wang et al, 2020; Lopez-Leon et al, 2021; de Paula et a., 2020) as contributing factors, future studies should address the etiology of cognitive symptoms as a direct consequence of SARS-CoV-2 neuroinfection.…”

“…In other neurotropic viral infections, cognitive sequelae may occur due to brain damage or dysfunction owing to vascular lesions and inflammatory processes (Levine, Sacktor & Becker, 2020). Persistent cognitive impairments from viral infections are associated with activities of daily living and psychosocial adaptation (de Paula et al, 2020). Much from COVID-19 consequences is still veiled from its novelty.…”
