Musical hallucination is a disorder of complex sound processing of instrumental music, songs, choirs, chants, etc. The underlying pathologies include moderate to severe acquired hearing loss (the auditory equivalent of Charles Bonnet syndrome), psychiatric illnesses (depression, schizophrenia), drug intoxication (benzodiazepines, salicylate, pentoxifylline, propranolol), traumatic lesions along the acoustic pathways, and epilepsy. The hallucinations are most likely to begin late in life; 70% of patients are women...

Jocelyn Y Cheng
Musicogenic epilepsy is a rare syndrome in which music triggers seizures. Affective network processing appears to play a key role in epileptogenesis. Many people with epilepsy suffer from comorbid affective disorders, the shared basis of which involves similar pathophysiologies, including deficiencies of serotonergic and noradrenergic function. Seizures and mood disorders may thus have reciprocal effects on one another, particularly in emotionally precipitated syndromes such as musicogenic epilepsy. I report a man with long-standing depression and anxiety who developed focal epilepsy that evolved into musicogenic seizures...

Robert J Spencer, Jaclyn Reckow, Lauren L Drag, Linas A Bieliauskas
OBJECTIVE: We assessed the validity of a brief incidental learning measure based on the Similarities and Vocabulary subtests of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV). BACKGROUND: Most neuropsychological assessments for memory require intentional learning, but incidental learning occurs without explicit instruction. Incidental memory tests such as the WAIS-III Symbol Digit Coding subtest have existed for many years, but few memory studies have used a semantically processed incidental learning model...

BACKGROUND AND OBJECTIVE: Although many patients present with functional neurological symptoms (FNS), few US clinics offer specialized FNS care, and data on clinic attendees remain limited. We determined predictors of initial attendance, symptom burden, and FNS subtype in the first patients referred to our Functional Neurological Disorders Clinic for suspected FNS. METHODS: We reviewed the charts of 62 consecutive patients (46 women, 16 men). Regression analyses investigated predictors of keeping the first scheduled clinic appointment...

OBJECTIVE AND BACKGROUND: More than 10% of patients clinically diagnosed with Parkinson disease demonstrate normal dopamine uptake on dopamine transporter single-photon emission computed tomography (DaTscan), but little is known about how cognitive function differs between patients with dopamine deficiency on DaTscan and patients with scans without evidence of dopaminergic deficit (SWEDD). We compared the cognitive function of these two groups of patients over 2 years. METHODS: We retrospectively analyzed data obtained from the Parkinson's Progression Markers Initiative on 309 participants clinically diagnosed with idiopathic Parkinson disease who had scored in the normal range on the Montreal Cognitive Assessment at baseline and had completed 1- and 2-year follow-up visits...

Delirium is a transient condition characterized by sudden and fluctuating disturbances in cognitive function. The condition can be considered a sign of the brain's vulnerability and diminished resilience to insult. Among the many clinical manifestations are cognitive, psychomotor, and sleep disturbances. Delirium is associated with longer hospital stays, worse functional outcomes, and higher mortality. Although up to 48% of patients who have had a stroke develop delirium, the condition has been studied much less in these patients than in general medicine, surgical, and intensive care patients...

Richard L Skolasky
Single-case experimental design (SCED) studies are particularly useful for examining the processes and outcomes of psychological and behavioral studies. Accurate reporting of SCED studies is critical in explaining the study to the reader and allowing replication. This paper outlines important elements that authors should cover when reporting the results of a SCED study. Authors should provide details on the participant, independent and dependent variables under examination, materials and procedures, and data analysis...

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...

#12
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...

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...
