ABSTRACT

INTRODUCTION: The number of people in the United States living with dementia is projected to rise to over 7.1 million in the next 12 years, representing a 40% increase from current levels. This anticipated "dementia tsunami" has led to a recent state and national policy emphasis on early detection, improved care quality, reduced caregiver burden, and increased access to care. The ability to achieve these objectives is limited by few dementia specialists in rural and small communities and the challenges of travel to and within congested urban regions for dementia patients and their caregivers. Telemedicine is one such means for responding to this lack of access to subspecialty assessment and care. We describe our early experiences with this technology applied to neuropsychological assessments, with data from 31 patients. METHODS: As part of an interdisciplinary dementia care demonstration project, clinical video teleconferencing provides real-time high resolution video interactions between dementia subspecialists in a major metropolitan medical center and patients in 3 outlying clinics located 180, 150, and 100 miles away. Comprehensive neuropsychological assessments, designed to address referral questions related to neurocognitive disorders via clinical video teleconferencing, are conducted as one component of interdisciplinary care. OUTCOMES: Eighty-seven percent of patients referred for neuropsychological assessment had an inaccurate neurocognitive diagnosis at the time of referral. Unmet and unrecognized mental health treatment needs were identified in over 77% of patients. In addition, acceptance was good for patients, caregivers, and clinicians. DISCUSSION: Teleneuropsychology is proving to be an excellent resource for clarifying cognitive and psychiatric diagnoses, and integrating individual strengths, weaknesses, and preferences into treatment and care plans used by other health care providers, patients, and caregivers.

ABSTRACT

Corpus callosum malformation and dysfunction are increasingly recognized causes of cognitive and behavioral disability. Individuals with agenesis of the corpus callosum (AgCC) offer unique insights regarding the cognitive skills that depend specifically upon callosal connectivity. We examined the impact of AgCC on cognitive inhibition, flexibility, and processing speed using the Color-Word Interference Test (CWIT) and Trail Making Test (TMT) from the Delis-Kaplan Executive Function System. We compared 36 individuals with AgCC and IQs within the normal range to 56 matched controls. The AgCC cohort was impaired on timed measures of inhibition and flexibility; however, group differences on CWIT Inhibition, CWIT Inhibition/Switching and TMT Number-Letter Switching appear to be largely explained by slow performance in basic operations such as color naming and letter sequencing. On CWIT Inhibition/Switching, the AgCC group was found to commit significantly more errors which suggests that slow performance is not secondary to a cautious strategy. Therefore, while individuals with agenesis of the corpus callosum show real deficits on tasks of executive function, this impairment appears to be primarily a consequence of slow cognitive processing. Additional studies are needed to investigate the impact of AgCC on other aspects of higher order cortical function.
