Background Previous studies have argued that there are two types of linguistic gender: grammatical gender, which is arbitrarily assigned to nouns, and semantic depends on the gender referent.Aim We explore hypothesis these entail distinct cognitive processes by investigating performance people with aphasia at level sentence processing.Methods Procedure Nine (seven fluent aphasia) a control grou...

BACKGROUND Enlarged perivascular spaces (PVS) are common magnetic resonance imaging (MRI) findings, whereas widespread enlarged PVS are extremely rare. Although most patients with widespread enlarged PVS remain asymptomatic, some develop neurological dysfunctions; however, it remains unclear whether these are the consequence of widespread enlarged PVS. CASE PRESENTATION A 64-year-old female p...

Objective To investigate progressive non-fluent aphasia and histopathologically-proven corticobasal degeneration. Methods We evaluated symptoms, signs, neuropsychological deficits, and radiology data longitudinally, in a patient with autopsy-proven corticobasal degeneration and correlated these observations directly to the neuroanatomic distribution of the disease. Results At presentation, ...

BACKGROUND Hippocampal atrophy on magnetic resonance imaging (MRI) is an early characteristic of Alzheimer's disease. However, hippocampal atrophy may also occur in other dementias, such as frontotemporal lobar degeneration (FTLD). OBJECTIVE To investigate hippocampal atrophy on MRI in FTLD and its three clinical subtypes, in comparison with Alzheimer's disease, using volumetry and a visual r...

Language is often assumed to rely on domain-specific neurocognitive substrates. However, this human capacity in fact seems to crucially depend on generalpurpose memory systems in the brain. Evidence suggests that lexical memory relies heavily on declarative memory, which is specialized for arbitrary associations and is rooted in temporal lobe structures. The mental grammar instead relies largel...

She was reportedly studying Spanish as a second language. A full neurological workup and a detailed speech-language assessment were conducted. Neurological examination revealed a conscious alert lady with intact power in all 4 extremities, grade 5/5 (Medical Research Council grade) and down going plantars. There were no sensory deficits, and cortical sensations were intact. Visual fields could ...

The existence of progressive aphasias has been known for more than 100 years. Pick (1892, 1904), Sérieux (1893), Franceschi (1908), and Rosenfeld (1909) were among the first to report such patients. The current resurgence of interest in this condition can be traced to a 1982 report of six patients with a slowly progressive aphasia and to the subsequent delineation of the primary progressive aph...
