The Piano Man: A Case Report of Anterior Thalamic Infarct with Dementia and Preserved Music Ability
CONCLUSIONS: The case has implications for understanding the complex integrative functions of the thalamus, including how profound impairment can simultaneously present with cognitive strengths that may not be captured by performance on neuropsychological testing. This case also suggests that magnetic resonance imaging may be indicated in cases presenting with vascular risk factors and sudden onset cognitive impairment, given that computed tomography may not be sensitive to small subcortical infarcts.PMID:37699427 | DOI:10.1093/arclin/acad069

Stroke and molecular imaging: a focus on FDG-PET
Am J Nucl Med Mol Imaging. 2023 Apr 25;13(2):51-63. eCollection 2023.ABSTRACTStroke is the leading cause of disability worldwide, the second most common cause of dementia and the third leading cause of death. Though the etiology of stroke has been explored extensively, there remains open questions in the scientific and clinical study of stroke. Traditional imaging techniques, such as magnetic resonance imaging and computed tomography, have been applied extensively and remain mainstays in clinical practice. Nevertheless, positron emission tomography has proven to be a powerful molecular imaging tool in exploring the scienti...

Sensors, Vol. 23, Pages 1900: Multi Modal Feature Extraction for Classification of Vascular Dementia in Post-Stroke Patients Based on EEG Signal
This study used 19 EEG channels recorded from normal elderly, post-stroke with mild cognitive impairment, and post-stroke with dementia. The QEEG method used for feature extraction includes relative power, coherence, and signal complexity; the evaluation performance of normal-mild cognitive impairment-dementia classification was conducted using Support Vector Machine and K-Nearest Neighbor. The results of the classification simulation showed the highest accuracy of 96% by Gaussian SVM with a sensitivity and specificity of 95.6% and 97.9%, respectively. This study is expected to be an additional criterion in the diagnosis o...

Detecting the vulnerable carotid plaque: the Carotid Artery Multimodality imaging Prognostic study design
Background
Carotid artery disease is highly prevalent and a main cause of ischemic stroke and vascular dementia. There is a paucity of information on predictors of serious vascular events. Besides percentage diameter stenosis, international guidelines also recommend the evaluation of qualitative characteristics of carotid artery disease as a guide to treatment, but with no agreement on which qualitative features to assess. This inadequate knowledge leads to a poor ability to identify patients at risk, dispersion of medical resources, and unproven use of expensive and resource-consuming techniques, such as magnetic reso...

60 Years of Achievements by KSNM in Neuroimaging Research
Nucl Med Mol Imaging. 2022 Feb;56(1):3-16. doi: 10.1007/s13139-021-00727-1. Epub 2022 Jan 15.ABSTRACTNuclear medicine neuroimaging is able to show functional and molecular biologic abnormalities in various neuropsychiatric diseases. Therefore, it has played important roles in the clinical diagnosis and in research on the normal and pathological states of the brain. More than 400 outstanding studies have been conducted by Korean researchers over the past 60 years. In the 1990s, when multiheaded single-photon emission computed tomography (SPECT) scanners were first introduced in South Korea, stroke research using brain perfu...

Intravascular large B-cell lymphoma presenting as rapidly progressive dementia and stroke: A case report
Rationale:
Intravascular large B-cell lymphoma (IVLBCL) is a rare form of large B-cell non-Hodgkin lymphoma. The diagnosis is challenging and frequently made at biopsy. Here we reported a case of IVLBCL limited to the central nervous system (CNS) presenting with progressive dementia and acute stroke, who was diagnosed by brain biopsy.
Patient concerns:
A 47-year-old woman was transferred to our hospital with a 6-month history of rapidly progressive dementia, and left limb weakness and numbness for 3 days. She was successively misdiagnosed with inflammatory demyelinating disease and stroke. Her condition deterior...

IJERPH, Vol. 18, Pages 10633: Socio-Economic Disparities in Access to Diagnostic Neuroimaging Services in the United Kingdom: A Systematic Review
This study includes the analysis of diagnostic imaging used for dementia, minor head injury, stroke, cancer, epilepsy, chronic inflammatory demyelinating polyneuropathy and Parkinson’s disease. With this study, we aim to assess the health inequalities at disease diagnosis. Methods: Using Medline (via Ovid), PubMed and Web of Science databases as sources of information, we critically appraise existing studies on neuroimaging use in the U.K. health care system, published between January 2010 and February 2021. Findings: A total of 18 studies were included in this research, revealing that there was an increase in patients o...

Clinical and radiological aspects of bilateral temporal abnormalities: pictorial essay
Abstract The temporal lobes are vulnerable to several diseases, including infectious, immune-mediated, degenerative, vascular, metabolic, and neoplastic processes. Therefore, lesions in the temporal lobes can pose a diagnostic challenge for the radiologist. The temporal lobes are connected by structures such as the anterior commissure, corpus callosum, and hippocampal commissure. That interconnectedness favors bilateral involvement in various clinical contexts. This pictorial essay is based on a retrospective analysis of case files from a tertiary university hospital and aims to illustrate some of the conditions that simul...

Respiratory Syncytial Virus Outbreak in a Veterans Affairs Long-term Care Facility
Conclusions
Respiratory syncytial virus is highly infectious and can easily cause an outbreak in an LTCF. Polymerase chain reaction testing was contributory to identify cases rapidly. Rapid PCR results and intensified infection control measures were instrumental to halt the outbreak.

Prognostic value of 99m Tc-ECD brain perfusion SPECT in patients with atrial fibrillation and dementia
ConclusionThis study demonstrated that decreased cerebral blood flow in the temporo-parieto-occipital lobe could be a potential prognostic value in patients with both AF and dementia.

One-year prognosis of non-traumatic cortical subarachnoid haemorrhage: a prospective series of 34 patients
ConclusionsThe most frequent causes of cSAH in our series were cerebral amyloid angiopathy, ischaemic stroke, and vasculitis. This type of haemorrhage has a worse prognosis than other non-aneurysmal cSAH. There are numerous possible causes, and prognosis depends on the aetiology. In elderly patients, intracranial haemorrhage is frequently associated with cognitive impairment.ResumenIntroducciónLas hemorragias subaracnoideas corticales (HSAc) tienen numerosas etiologías. No hay estudios prospectivos que indiquen su evolución a largo plazo. El objetivo de este trabajo es describir las características clínicas y etiológ...
