Although the diagnosis of dementia still is primarily based on clinical criteria, neuroimaging is playing an increasingly important role. This is in large part due to advances in techniques that can assist with discriminating between different syndromes. Magnetic resonance imaging remains at the core of differential diagnosis, with specific patterns of cortical and subcortical changes having diagnostic significance. Recent developments in molecular PET imaging techniques have opened the door for not only antemortem but early, even preclinical, diagnosis of underlying pathology. This is vital, as treatment trials are underway for pharmacological agents with specific molecular targets, and numerous failed trials suggest that earlier treatment is needed. This article provides an overview of classic neuroimaging findings as well as new and cutting-edge research techniques that assist with clinical diagnosis of a range of dementia syndromes, with an emphasis on studies using pathologically proven cases.

Objective: Teleneuropsychology (TeleNP) and the ethical guidance related to TeleNP is not new. However, the emergence of the coronavirus-2019 (COVID-19) has generated renewed interest in the potential utility and feasibility of transitioning the clinical practice of neuropsychological assessment from an in-person evaluation to one that occurs at least partially via telehealth. Recent surveys of neuropsychologists practicing in the early stages of COVID-19 indicate that, while most clinicians will or currently engage in TeleNP services, many have concerns about ethical issues related to providing TeleNP. Despite the presence of APA guidelines for telepsychology, no formal APA ethical guidelines or standards of practice exist for TeleNP. We provide ethical considerations and suggestions for potential practitioners of TeleNP based on new models of practice derived in response to the COVID-19 pandemic. Method: We provide operational definitions of TeleNP and its models including: In-Clinic, Home, and Hybrid TeleNP models. Results: We outline ethical considerations and suggestions in general and by model related to: issues of competence, education and training, benefits and risks of conducting TeleNP, health disparities, informed consent, patient privacy, confidentiality, test security, and administration and interpretation of standardized assessments. Conclusions: The decision of which TeleNP model to use is a difficult one. Providers must balance several ethical considerations to complete an accurate assessment while managing numerous inherent challenges. Future efforts should focus on the creation of formal ethical guidelines and standards for the practice of TeleNP through joint task force efforts (e.g., APA, Inter Organizational Practice Committee).

Research reviews are presented for articles “Comparing telehealth-based and clinic-based group cognitive behavioral therapy for adults with depression and anxiety: A pilot study” by N. Khatri et al. and “Cognitive processing therapy for posttraumatic stress disorder delivered to rural veterans via telemental health: A randomized noninferiority clinical trial” by L. A. Morland et al. The studies focused on comparing the effects of face-to-face and videoconferencing modalities on group therapy.
