Leftward Bias of Visual Attention in Patients with End-Stage Renal Disease Receiving Dialysis: A Neglected Phenomenon
Conclusions:
Patients with ESRD receiving dialysis appear to have an impaired ability to correctly allocate their spatial attention (spatial neglect). Although the reason for the patients’ leftward bias needs to be elucidated, ESRD and/or dialysis may have induced right frontal-subcortical dysfunction that disinhibited the right parietal lobe, producing a left-sided attentional bias. Further studies are needed to test this hypothesis. (Source: Cognitive and Behavioral Neurology)

Apathy and Cognitive Deficits in Patients with Transient Global Ischemia After Cardiac Arrest
Conclusions:
Transient global ischemia after cardiac arrest generally leads to a broad pattern of cognitive decline with predominating memory deficits. Apathy is a frequent sequela and is associated with cognitive deficits, independent of depression. Studies investigating the cognitive profile after cardiac arrest should account for modulating influences of apathy. (Source: Cognitive and Behavioral Neurology)

Semantic Feature Disturbance in Alzheimer Disease: Evidence from an Object Decision Task
Conclusions:

CERAD Neuropsychological Battery–Arabic Version: Regression-Based and Stratified Normative Data and Effects of Demographic Variables on Cognitive Performance in Older Omanis
Conclusions:
Lower education level was associated with poorer CERAD-ArNB performance in a sample of cognitively normal Omanis aged 50 years and older. The normative data obtained from this study will help clinicians correctly interpret cognitive performance in the Omani elderly population, and probably in other, culturally similar Arabic-speaking communities.

Comparison of Two Versions of the Hospital Anxiety and Depression Scale in Assessing Depression in a Neurologic Setting
Conclusions:
The HADS-D is an easy-to-use and clinically relevant self-report psychometric scale for detecting depression in MS. Removing the “slowed down” item from the HADS-D does not influence its internal consistency, and both versions have similar associations with clinical outcomes.

Functional Reorganization of Right Prefrontal Cortex Underlies Sustained Naming Improvements in Chronic Aphasia via Repetitive Transcranial Magnetic Stimulation
Conclusions:
This study found that rTMS to the right hemisphere Broca area homologue confers long-lasting improvements in picture naming performance. The mechanism involves dynamic bilateral neural network changes in language processing, which take place within the right prefrontal cortex and the left hemisphere more generally.

Seronegative Paraneoplastic Limbic Encephalitis Associated with Thymoma
Paraneoplastic limbic encephalitis is an autoimmune syndrome characterized by the acute or subacute onset of encephalopathy, memory loss, confusion, temporal lobe seizures, and behavioral and mood changes. Although most patients with paraneoplastic limbic encephalitis have antineuronal antibodies, advances in the field now permit the diagnosis without autoantibody test results. In this case illustrating the new diagnostic criteria, we report a 70-year-old woman who was brought to the emergency room after the acute onset of cognitive impairment, altered mental status, and choreoathetoid movements. Brain magnetic resonance i...

Peduncular Hallucinosis and Autonomic Dysfunction in Anti-Aquaporin-4 Antibody Syndrome
We report a man with severe, debilitating symptoms resulting from a symptomatic lesion within the diencephalon, manifesting with abnormal circadian rhythms, autonomic dysfunction, behavioral disturbance, and complex visual hallucinations. The patient reported seeing nonexistent small people and animals, streaks of color across people’s faces, movement of objects and facial features, water cascading down walls, bright spots, and writing appearing as hieroglyphics. His centrally driven sick sinus syndrome required insertion of a permanent cardiac pacemaker. We have been able to suppress his disease activity with methotrexa...

Hemispheric Dominance for Stereognosis in a Patient With an Infarct of the Left Postcentral Sensory Hand Area
The concept of left hemispheric dominance for praxis, speech, and language has been one of the pillars of neurology since the mid-19th century. In 1906, Hermann Oppenheim reported a patient with bilateral stereoagnosia (astereognosis) caused by a left parietal lobe tumor and proposed that the left hemisphere was also dominant for stereognosis. Surprisingly, few cases of bilateral stereoagnosia caused by a unilateral cerebral lesion have been documented in the literature since then. Here we report a 75-year-old right-handed man who developed bilateral stereoagnosia after suffering a small infarct in the crown of the left po...

The Reading the Mind in the Eyes Test: Validity and Reliability of the Thai Version
Background and Objective: Until now there has not been a validated measure of theory of mind available in the Thai language. Our goal in this study was to assess the validity and reliability of our Thai-language translation of the Reading the Mind in the Eyes Test (the “Eyes Test”).
Methods: We gave our Thai version of the Eyes Test to 70 participants: 30 people with schizophrenia and 40 normal controls. We also gave Thai versions of the Faces Test and the Addenbrooke’s Cognitive Examination to assess convergent validity.
Results: For known groups validity, the controls scored significantly higher than the particip...

Blood Pressure Variability and Cognitive Function Among Older African Americans: Introducing a New Blood Pressure Variability Measure
Conclusions: In a sample of cognitively intact older African American adults, BP variability did not correlate with global cognitive function, as measured by the MMSE. However, higher diastolic BP variability correlated with poorer verbal and incidental memory. By accounting for differences in BP measurement intervals, our new BP variability index may help alert primary care physicians to patients at particular risk for cognitive decline.

Semantic Memory in the Clinical Progression of Alzheimer Disease
Conclusions: Semantic-lexical retrieval and lexical search may represent distinct aspects of semantic memory. Semantic memory processes are sensitive to cognitive decline and dementia severity in Alzheimer disease. (Source: Cognitive and Behavioral Neurology)
