BACKGROUND: Stroke patients with mild-moderate upper extremity motor impairments and minimal sensory and cognitive deficits provide a useful model to study recovery and improve rehabilitation. Laboratory-based investigators use lesioning techniques for similar goals. OBJECTIVE: To determine whether stroke lesions in an upper extremity rehabilitation trial cohort match lesions from the preclinical stroke recovery models used to drive translational research. METHODS: Clinical neuroimages from 297 participants enrolled in the Interdisciplinary Comprehensive Arm Rehabilitation Evaluation (ICARE) study were reviewed...

Foreign accent syndrome is a rare motor speech disorder that causes patients to speak their language with a non-native accent. In the neurogenic condition, the disorder develops after lesions in the language dominant hemisphere, often affecting Broca's area, the insula, the supplementary motor area and the primary motor cortex. Here, we present two new cases of FAS after posterior fossa lesions. The first case is a 44-year-old, right-handed, Dutch-speaking man who suffered motor speech disturbances and a left hemiplegia after a pontine infarction...

Adults are living longer, and cardiovascular disease is endemic in the growing population of older adults who are surviving into old age. Functional capacity is a key metric in this population, both for the perspective it provides on aggregate health and as a vital goal of care. Whereas cardiorespiratory function has long been applied by cardiologists as a measure of function that depended primarily on cardiac physiology, multiple other factors also contribute, usually with increasing bearing as age advances...

Perivascular spaces that are visible on magnetic resonance imaging (MRI) are a neuroimaging marker of cerebral small vessel disease. Their location may relate to the type of underlying small vessel pathology: those in the white matter centrum semi-ovale have been associated with cerebral amyloid angiopathy, while those in the basal ganglia have been associated with deep perforating artery arteriolosclerosis. As cerebral amyloid angiopathy is an almost invariable pathological finding in Alzheimer's disease, we hypothesized that MRI-visible perivascular spaces in the centrum semi-ovale would be associated with a clinical diagnosis of Alzheimer's disease, whereas those in the basal ganglia would be associated with subcortical vascular cognitive impairment...

In the last decade, testosterone replacement therapy (TRT) has been increasingly prescribed to treat a controversial condition known as 'late-onset hypogonadism (LOH)'. This syndrome is diagnosed in men who, for no discernible reason other than older age, obesity or ill health have serum testosterone concentrations below the normal range for healthy young men and report one or more of the following symptoms: muscle weakness or wasting, mood, behaviour and cognition-related symptoms and sexual function or libido impairment...

The sudden occurrence of a focal neurological deficit, sometimes transitory and fluctuating, must lead to a suspicion of a stroke, including in a child. The preferred examination is magnetic resonance imaging with magnetic resonance angiography in an emergency. The sequelae of stroke are common and severe. Urgent diagnosis and adapted care can help to improve morbidity-mortality. Rehabilitation starts early and must systematically screen for cognitive or language impairment. The management of a stroke in a child must be planned for in multi-disciplinary protocols established before the patient's arrival at hospital...

Bilingualism has been found to delay onset of dementia and this has been attributed to an advantage in executive control in bilinguals. However, the relationship between bilingualism and cognition is complex, with costs as well as benefits to language functions. To further explore the cognitive consequences of bilingualism, the study used Frontotemporal dementia (FTD) syndromes, to examine whether bilingualism modifies the age at onset of behavioral and language variants of Frontotemporal dementia (FTD) differently...

Arterial hypertension (HT) and other vascular pre-existing conditions (PEC) generate asymptomatic brain damage which increases the occurrence of stroke and cognitive decline. The aim of this work was to explore if serum antibodies against the NR2 subunit of the NMDA receptor (NR2Ab) could predict subclinical brain damage (SBD) in hypertensive patients with PEC. Forty seven neurologically asymptomatic hypertensive subjects were classified according to the number of PEC (retinopathy, overweight/obesity, diabetes mellitus and dyslipidemia)...

Cerebral amyloid angiopathy (CAA) is a common cause of cognitive impairment in older individuals. This study aimed to investigate predictors of dementia in CAA patients without intracerebral hemorrhage (ICH). A total of 158 non-demented patients from the Stroke Service or the Memory Clinic who met the modified Boston Criteria for probable CAA were included. At baseline, neuroimaging markers, including lobar microbleeds (cerebral microbleeds (CMBs)), white matter hyperintensities (WMH), cortical superficial siderosis (cSS), magnetic resonance imaging (MRI)-visible centrum semiovale perivascular spaces (CSO-PVS), lacunes, and medial temporal atrophy (MTA) were assessed...
