Neuromodulation of Right Auditory Cortex Selectively Increases Activation in Speech-Related Brain Areas in Brainstem Auditory Agnosia
Auditory agnosia is an inability to make sense of sound that cannot be explained by deficits in low-level hearing. In view of recent promising results in the area of neurorehabilitation of language disorders after stroke, we examined the effect of transcranial direct current stimulation (tDCS) in a young woman with general auditory agnosia caused by traumatic injury to the left inferior colliculus. Specifically, we studied activations to sound embedded in a block design using functional magnetic resonance imaging before and after application of anodal tDCS to the right auditory cortex. Before tDCS, auditory discrimination ...

Performance of Patients with Early Parkinson Disease on an Executive and Social Cognition Battery
Conclusions:
We found that, used along with traditional neuropsychological tasks, the ESCB may be useful in providing a more comprehensive evaluation of frontal dysfunction among patients with PD, thus contributing to the early diagnosis of cognitive disorders in this patient population.

Diagnostic Overshadowing of Anxiety in Parkinson Disease: Psychosocial Factors and a Cognitive-Behavioral Model
Anxiety in Parkinson disease (PD) is highly prevalent yet frequently underdiagnosed and undertreated, and historically overshadowed in research by a focus on depression. Recently, interest in anxiety has been building with the recognition of its significant impact on quality of life in PD. Anxiety is typically conceptualized as one of many “nonmotor” manifestations of neurologic change, with minimal consideration of potentially important psychosocial factors. This narrative review used a systematic search strategy to identify and synthesize the available evidence for psychosocial risk factors for anxiety. Thirty releva...

Transient Capgras Syndrome Secondary to Bilateral Ischemic Stroke: A Case Report
We present a case of transient Capgras syndrome following bilateral cerebral ischemic infarcts in the frontal, parietal, and temporal regions, and involving the right prefrontal cortex. To our knowledge, transient Capgras syndrome with rapid resolution over a period of days is rare. (Source: Cognitive and Behavioral Neurology)

Central Visual Oscillopsia: Case Report and Review of the Literature
Here we present a patient with persistent central visual oscillopsia, review the literature on this condition, and report results from an experimental intervention using repetitive transcranial magnetic stimulation. A 57-year-old man reported persistent visual oscillopsia after a traumatic brain injury suffered 20 years earlier. Symptoms were presumed to be of cortical origin given his normal eye movements, eye stability, and peripheral vestibular function. Furthermore, he reported oscillopsia with visual imagery during eye closure. Occipital lesions damaging white matter connections identified on magnetic resonance imagin...

Influence of Serotonin Transporter SLC6A4 Genotype on the Effect of Psychosocial Stress on Cognitive Performance: An Exploratory Pilot Study
Conclusions:
Genetic susceptibility to stress conferred by SLC6A4 appeared to modulate unconstrained cognitive flexibility during psychosocial stress in this exploratory sample. If confirmed, this finding may have implications for conditions associated with increased stress response, including performance anxiety and cocaine withdrawal. Future work is needed both to confirm our findings with a larger sample and to explore the mechanisms of this proposed effect. (Source: Cognitive and Behavioral Neurology)

Auditory Brainstem Pathology in Autism Spectrum Disorder: A Review
Atypical responses to sound are common in individuals with autism spectrum disorder (ASD), and growing evidence suggests an underlying auditory brainstem pathology. This review of the literature provides a comprehensive account of the structural and functional evidence for auditory brainstem abnormalities in ASD. The studies reviewed were published between 1975 and 2016 and were sourced from multiple online databases. Indices of both the quantity and quality of the studies reviewed are considered. Findings show converging evidence for auditory brainstem pathology in ASD, although the specific functions and anatomical struc...
