RESUMO
Introduction: Publications on the integration of telehealth in the care of patients with movement disorders are increasing, but little has been presented regarding its use in tardive dyskinesia (TD), a drug-induced movement disorder associated with prolonged exposure to dopamine receptor blocking agents. This study was conducted to address that knowledge gap, based on insights from a panel of TD experts. Methods: In 2020, six neurologists, three psychiatrists, and three psychiatric nurse practitioners participated in individual semistructured interviews about in-person and virtual TD assessment and management in their practices. Two virtual roundtables were then conducted to consolidate findings from these interviews. Results: The panel agreed that despite the challenges of virtual TD assessment (e.g., technology issues, difficulty observing entire body, inability to conduct thorough neurological examinations), telehealth can offer benefits (e.g., fewer missed appointments, reduced time/cost, easier access to family/caregiver feedback). The panel also agreed that telehealth should be combined with periodic in-person visits, and they recommended an in-person TD assessment within 6 months before the first virtual visit and at least one in-person assessment every 6 months thereafter. Additional best practices for TD telehealth included implementing video, involving family/caregivers, and providing preappointment instructions to help patients prepare their technology and environment. Conclusions: Telehealth is not a substitute for in-person visits but can be a helpful complement to in-person clinical care. Clinicians can optimize virtual visits in patients at risk of TD by using targeted questions to identify TD and evaluate its impact and by providing education about approved TD treatments.

The objective of this study is to better define the pathological characteristics of pathologically proven progressive supranuclear palsy (PSP) presenting with the corticobasal syndrome (CBS). PSP is characterized by early falls, vertical supranuclear ophthalmoplegia, and axial rigidity, whereas asymmetric limb features, including rigidity, bradykinesia, apraxia, alien limb phenomena, and cortical sensory loss are characteristic of CBS. We investigated clinicopathological characteristics of 5 cases of PSP that presented with CBS (CBS-PSP). Comprehensive pathological analysis was undertaken to determine the presence of concomitant pathological processes as well as quantitative tau burden in cortical regions of CBS-PSP, compared with 8 typical PSP cases (Typ-PSP). The clinical features in the CBS-PSP cases included asymmetrical features, apraxia, alien limb phenomena, and progressive aphasia. All cases had Parkinsonism, and vertical supranuclear ophthalmoplegia was noted in all but 1 case of CBS-PSP. Secondary neuropathological diagnoses included argyrophilic grain disease (AGD) in 1 of the 8 cases of Typ-PSP, whereas Alzheimer's disease (AD), Lewy body disease, AGD, and vascular disease was found in 3 cases of CBS-PSP. Image analysis of cortical tau burden performed in 8 Typ-PSP and 3 CBS-PSP cases revealed a significant increased tau burden in mid-frontal and inferior-parietal cortices in the CBS-PSP cases. This study demonstrates that when PSP presents as CBS, it is most likely due to either a concurrent cortical pathology from a secondary process such as AD or from the primary pathology of PSP extending into cortical areas that are primarily and commonly affected in CBD.
