Reports of involuntary ipsilateral movements after a stroke are rare, and none have described a patient with both an instinctive grasp reaction and tremor-like movement ipsilateral to the acute stroke lesion. We here report such a patient. A 76-year-old right-handed woman with a past history of left thalamic hemorrhage developed left hemiparesis, an instinctive grasp reaction, and a peculiar involuntary movement of her right arm. This involuntary movement was stereotyped and sometimes rhythmical, with a groping or picking-like action...

BACKGROUND AND OBJECTIVE: Many patients who have signs of neglect immediately after a right hemisphere stroke remain disabled even when they improve on tests of neglect. Few patients are tested for attentional persistence and fatigue despite their importance in many instrumental activities. To investigate whether stimulus repetition might alter the allocation of attention, we repeatedly tested a patient 16 weeks after she developed hemispatial neglect from a right hemisphere stroke. METHODS: During each of three testing sessions given in 1 day, we asked the patient to bisect 90 lines of two lengths, presented in 30-trial blocks in three locations: left, center, and right of her midsagittal plane, partially counterbalanced across sessions...

We report a 44-year-old woman, with a family history of early-onset dementia, presenting with primary progressive aphasia. This clinically variable syndrome has multiple underlying pathologies, and correlations between clinical manifestations and postmortem neuropathologic findings are controversial. Our patient suffered worsening language impairment with major word-finding difficulties but preserved comprehension. She also developed episodic memory impairment. Her condition progressed to dementia with behavioral changes...

OBJECTIVE: To investigate the relationship of dystonia symptoms to cognitive function by comparing cognitive performance in patients with focal (cervical) and generalized dystonia subtypes and examining the differential contributions of severity of symptoms and mood disorders to cognition. BACKGROUND: Studies of the nonmotor syndrome in isolated dystonia have reported evidence of cognitive dysfunction, but the cause of this impairment remains unclear. Several studies have suggested that poor cognitive performance reflects the distracting effects of the motor symptoms and/or a mood disorder...

BACKGROUND AND OBJECTIVE: In half to two thirds of patients who are diagnosed with mild cognitive impairment (MCI), the diagnosis neither converts to dementia nor reverts to normal cognition; however, little is known about predictors of MCI stability. Our study aimed to identify those predictors. METHODS: We obtained 3-year longitudinal data from the National Alzheimer's Coordinating Center Uniform Data Set for patients with a baseline diagnosis of MCI. To predict MCI stability, we used the patients' baseline data to conduct three logistic regression models: demographics, global function, and neuropsychological performance...

Howard S Kirshner
This paper comments on a companion article, a first-person account of an episode of transient global amnesia written by New York Times reporter Trip Gabriel (Gabriel T. 2017. Cogn Behav Neurol. 30:1-4). Mr Gabriel describes having no memories of a cold, rainy day that he had spent on a sailboat competing in two races. The episode may have been triggered by his exposure to water. Afterward, the skipper recalled that Mr Gabriel had functioned fine on the boat, although after returning to shore he needed help finding his car...

Trip Gabriel
In this vivid first-person case history, political reporter Trip Gabriel describes experiencing a classic episode of transient global amnesia. He was near the average target age of 61. Although no cause has been established for the syndrome, as with many other patients his episode appears to have been triggered by contact with water: He was racing a sailboat. While remaining alert and handling complex sailing maneuvers, he suddenly developed amnesia that left him with no recollection of finishing two races, returning to shore, drinking a beer with his friends, needing help finding his car, and not knowing where he was or where he lived...

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...

REVIEW
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...

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...

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...

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...

REVIEW
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...

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...

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...

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...
