#1
Massimiliano Ruggeri
Damage to the dorsomedial thalamus usually leads to impaired episodic memory, attention, and executive function, but the role of the dorsomedial thalamus in memory processing is still not fully understood. Clinical evidence is inconclusive about whether dorsomedial thalamic damage impairs recall or whether it impairs recognition. I report a unique patient who suffered a cardioembolic stroke in the paramedian artery territory, caused by a patent foramen ovale. He was left with a chronic ischemic lesion centered in the parvocellular and, to a lesser extent, the magnocellular portions of the left dorsomedial thalamic nucleus, and marginally involving the midline and intralaminar nuclei...

Christopher S Peckins, Leila Khorashadi, Edward R Wolpow
We present the case of a high-functioning 88-year-old woman who suddenly developed the persistent and disturbing belief that her home of 40 years was not genuine, but rather an accurate replica. Her episode was probably caused by a small stroke that left her with this single extremely specific deficit. We describe the patient in detail and link to a video interview of her 3 months after the onset of the delusion, eloquently describing her experience. We summarize some of the many reports and discussions of our patient's delusion, reduplicative paramnesia, as well as other delusional misidentification syndromes...

OBJECTIVE: We investigated the relationship between serum cystatin C (CysC) levels and cognitive dysfunction and disease progression in patients with Parkinson disease. BACKGROUND: Previous studies have reported altered CysC levels in neurodegenerative disorders, but only a few studies have explored the role of CysC and its relationship to cognitive dysfunction in Parkinson disease. METHODS: We measured serum levels of CysC, creatinine, urea, and uric acid in 142 patients with Parkinson disease and 146 healthy controls...

BACKGROUND AND OBJECTIVE: Several case reports have noted basal ganglia calcification (BGC) as an incidental radiologic finding in patients presenting with psychiatric manifestations. In this study, we examined the clinical correlates of mental disorders in two groups of psychiatric patients, one with BGC and one with normal radiologic studies. METHODS: In a retrospective cross-sectional case-control study of patients admitted to the psychiatric ward in Al Ain Hospital between January 2011 and December 2013, we compared all 15 patients diagnosed with BGC and 30 control patients who had normal radiologic findings...

#5
Jeremy T Hua, Kerry L Hildreth, Victoria S Pelak
Endogenous testosterone in the aging man has been scrutinized extensively in regard to its effects on performance in many cognitive domains, especially verbal fluency, visuospatial and visuoperceptual abilities, memory, and executive function. Studies of testosterone supplementation have sought to identify potential cognitive improvements in men with and without baseline cognitive impairment, and have had a wide range of results. The variability in outcomes is likely related, in part, to the lack of consensus on methods for testosterone measurement and supplementation and, in part, to the disparate measures of cognitive function used in randomized controlled studies...

Zaira Cattaneo, Alberto Pisoni, Marcello Gallucci, Costanza Papagno
In a prior study (Cattaneo et al, 2011. Neuroscience. 183:64-70), we demonstrated that anodal transcranial direct current stimulation (tDCS) over the left inferior frontal gyrus enhanced verbal fluency in healthy young adults. Although our data are in line with the results of other published studies, another research group recently failed to report anodal tDCS effects on verbal fluency using a paradigm similar to ours (Vannorsdall et al, 2016. Cogn Behav Neurol. 29:11-17). Here we discuss aspects of study design and interpretation of results that should be considered in replications, focusing particularly on homogeneity of procedures...

Meningiomas are common, usually benign intracranial tumors. They grow slowly and can remain asymptomatic for many years. Meningiomas can present as mental disorders rather than with neurologic signs or symptoms. In this case report we describe a middle-aged man with a 2-year history of depressive disorder who was diagnosed with a large olfactory fossa meningioma after he developed mental status changes and urinary incontinence. After the tumor was removed, the patient's depressive symptoms resolved and his neurocognitive functions improved...

Whipple disease is a rare, chronic multisystem infectious disease. The central nervous system (CNS) is secondarily involved in 43% of patients; 5% of patients have isolated or primary CNS involvement. The most frequent CNS symptoms are cognitive changes. Prosopagnosia is an inability to recognize familiar faces, in a person who does not have vision impairments or cognitive alterations. This relatively rare condition is usually related to vascular, traumatic, degenerative, or infectious lesions. We report a 54-year-old woman who presented subacutely with fever, headache, and seizures that led to a diagnosis of infectious meningoencephalitis...

BACKGROUND AND OBJECTIVE: Cognitive impairment predicts poor outcomes in patients with coronary artery disease (CAD), but much remains to be learned about these patients' cognitive function. We investigated how depression, anxiety, and Type D personality relate to cognitive function in patients with CAD, adjusting for sociodemographic factors and clinical markers of CAD severity. METHODS: We evaluated 510 consecutive patients with CAD (364 men, 146 women; mean age 58±9 years) but no history of coronary artery bypass graft surgery or cognitive impairment who were attending a cardiac rehabilitation program...

OBJECTIVE: To examine discriminant validity and test-retest reliability of the Zürich maxi mental status inventory (ZüMAX) in patients with stroke. BACKGROUND: The ZüMAX is a novel domain-specific cognitive assessment tool to screen for disturbances in neuropsychological function. The test can be used in stroke rehabilitation to estimate severity of cognitive impairment. Because evidence for validity and reliability is lacking, the tool's clinical use is limited...

Soo Jung Lee, Kyung Won Park, Lee-Suk Kim, HyangHee Kim
OBJECTIVE AND BACKGROUND: Along with auditory function, cognitive function contributes to speech perception in the presence of background noise. Older adults with cognitive impairment might, therefore, have more difficulty perceiving speech-in-noise than their peers who have normal cognitive function. We compared the effects of noise level and cognitive function on speech perception in patients with amnestic mild cognitive impairment (aMCI), cognitively normal older adults, and cognitively normal younger adults...

Nikolaos Korakas, Magda Tsolaki
Of the more than two million people worldwide with multiple sclerosis, 40% to 65% experience cognitive impairment, many of them early in the course of the disease. Cognitive impairment has been found in patients with all subtypes of multiple sclerosis. Because both pharmacologic and nonpharmacologic interventions may improve patients' brain function, cognitive assessment should be a routine part of the clinical evaluation. Traditional paper-and-pencil neuropsychological tests and batteries can help detect and monitor patients' cognitive problems...

We describe a right-brain-damaged patient with extrapersonal neglect, dysexecutive deficits, and closing-in. Because no study has investigated the relationship between spatial neglect and closing-in in patients with focal brain damage, we assessed how spatial factors (drawing direction: left-to-right, right-to-left, radial) and attentional load (single versus dual task copying; the concurrent task was counting aloud) interacted in determining our patient's closing-in. We found that her closing-in was worst when she copied the stimulus (Luria's line) from left to right; greater attentional load significantly worsened her closing-in in the right-to-left direction...

OBJECTIVE: This is a preliminary investigation into the effectiveness of semantic feature training for the treatment of anomia in Alzheimer disease (AD). BACKGROUND: Anomia is a common clinical characteristic of AD. It is widely held that anomia in AD is caused by the combination of cognitive deficits and progressive loss of semantic feature information. Therapy that aims to help participants relearn or retain semantic features should, therefore, help treat anomia in AD...

BACKGROUND AND OBJECTIVE: Major depressive disorder is a neuropsychiatric condition associated with neurochemical changes that alter levels of neurotrophins. We aimed to measure serum levels of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) in patients experiencing their first episode of major depression and to examine those levels in relation to the severity and duration of the depressive episode. METHODS: We recruited 85 participants: 44 drug-free patients with major depression (35 women, 9 men) and 41 healthy controls (32 women, 9 men)...

BACKGROUND AND OBJECTIVE: Healthy adults often deviate leftward on line bisection tasks (allocentric pseudoneglect) but rightward on body part bisection tasks (egocentric pseudoneglect). People visually estimate distance in peripersonal space by comparing the distance to the length of a body part such as an arm's length (an egocentric reference) or using standard units of distance such as inches (an allocentric reference). Our objective was to learn whether people have pseudoneglect when estimating distances in peripersonal space using egocentric versus allocentric reference frames...

BACKGROUND: Transcranial direct current stimulation (tDCS) has been shown to enhance verbal productivity, but the finding and extent of enhancement vary across studies. Few attempts to replicate positive tDCS findings have been reported, suggesting the possibility of publication bias. OBJECTIVE: We aimed to replicate the tDCS methodology and findings of Cattaneo, Pisoni, and Papagno (2011, Neuroscience 183:64-70) in a new population sample. We hypothesized that our study of anodal tDCS would improve verbal fluency production similarly to the original study...

BACKGROUND AND OBJECTIVE: Acute and early human immunodeficiency virus infection (AEH) is accompanied by neuroinflammatory processes as well as impairment in neurocognitive and everyday functions, but little is known about the frequency and clinical correlates of the neurobehavioral disturbances during this period. We compared pre-seroconversion with current levels of apathy, disinhibition, and executive dysfunction; we also examined everyday function and HIV disease correlates of neuropsychiatric impairment in individuals with AEH...

OBJECTIVE: To study whether pressure of speech in jargon aphasia arises out of disturbances to core language or executive processes, or at the intersection of conceptual preparation. BACKGROUND: Conceptual preparation mechanisms for speech have not been well studied. Several mechanisms have been proposed for jargon aphasia, a fluent, well-articulated, logorrheic propositional speech that is almost incomprehensible. METHODS: We studied the vast quantity of jargon speech produced by patient J...

OBJECTIVE: We studied activities of daily living (ADL) in Parkinson disease (PD) to identify the cognitive ADL impairments that could differentiate patients with PD dementia from those without dementia. BACKGROUND: Most people with PD have impairments in their ADL, making it difficult to distinguish between those caused by cognitive or motor dysfunction. METHODS: We evaluated 24 patients with PD dementia and 48 with PD without dementia. For comparison, we evaluated 24 patients with Alzheimer disease and 25 healthy control participants...
