Computerized cognitive training in post-treatment hematological cancer survivors: a feasibility study.

Background: Computerized cognitive training (CCT) programs have shown some effectiveness in alleviating cognitive symptoms in long-term cancer survivors. For patients presenting with cognitive symptoms in the early post-treatment phase, the benefit of CCT is unclear. To assess the possibility of testing the effectiveness of CCT in the early post-treatment period, our aim was to investigate the feasibility of an 8-week home-based, online CCT intervention among patients who have recently completed treatment for hematological malignancy.

Paraneoplastic opsoclonus-myoclonus syndrome as a rare presentation of breast cancer.

Opsoclonus-myoclonus paraneoplastic syndrome is a medical condition that includes opsoclonus along with diffuse or focal body myoclonus and truncal titubation with or without ataxia and other cerebellar signs. This rare neurological syndrome is poorly understood and can result in long-term cognitive, behavioral and motor sequelae. We report a case of a 49-year-old woman with anti-Ri antibody opsoclonus-myoclonus syndrome and an invasive ductal carcinoma with axillary nodes involvement.

Normal appearing white matter permeability: a marker of inflammation and information processing speed deficit among relapsing remitting multiple sclerosis patients.

Purpose: Blood-brain barrier breakdown (BBBB) occurs in relapsing remitting multiple sclerosis (RRMS). Relative recirculation (rR), a BBBB surrogate, may show inflammation undetectable by gadolinium. We compared normal appearing white matter (NAWM) rR in patients with and without disability measured with Symbol Digit Modalities Test and the Expanded Disability Status Scale (EDSS).

The relationship between white matter fiber damage and gray matter perfusion in large-scale functionally defined networks in multiple sclerosis.

Background: Recent studies utilizing perfusion as a surrogate of cortical integrity show promise for overall cognition, but the association between white matter (WM) damage and gray matter (GM) integrity in specific functional networks is not previously studied.

Objective: To investigate the relationship between WM fiber integrity and GM node perfusion within six functional networks of relapsing-remitting multiple sclerosis (RRMS) and secondary progressive multiple sclerosis (SPMS) patients.

Methods: Magnetic resonance imaging (MRI) and neurocognitive testing were performed on 19 healthy controls (HC), 39 RRMS, and 45 SPMS patients.

Perfusion reduction in the absence of structural differences in cognitively impaired versus unimpaired RRMS patients.

Background: Cognitive impairment affects 40%-68% of relapsing-remitting multiple sclerosis (RRMS) patients. Gray matter (GM) demyelination is complicit in cognitive impairment, yet cortical lesions are challenging to image clinically. We wanted to determine whether cortical cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT) differences exist between cognitively impaired (CI) and unimpaired (NI) RRMS.

Regional reduction in cortical blood flow among cognitively impaired adults with relapsing-remitting multiple sclerosis patients.

Purpose: Detection of cortical abnormalities in relapsing-remitting multiple sclerosis (RRMS) remains elusive. Structural magnetic resonance imaging (MRI) measures of cortical integrity are limited, although functional techniques such as pseudo-continuous arterial spin labeling (pCASL) show promise as a surrogate marker of disease severity. We sought to determine the utility of pCASL to assess cortical cerebral blood flow (CBF) in RRMS patients with (RRMS-I) and without (RRMS-NI) cognitive impairment.
