BACKGROUND: Alzheimer's disease (AD) is the most common cause of dementia and early and accurate diagnosis is important. Olfactory dysfunction is an early sign of AD. The contribution by test of olfactory function has been surveyed in AD vs a line of conditions but remains to be settled in the workup of unselected patients referred with suspected dementia. METHODS: We performed a two-step investigation: first, a comparative study of healthy controls and probable AD patients to test the applicability of the chosen scents (cuisine study); second, a study of consecutive patients referred to our geriatric outpatient clinic for suspected dementia with the investigating personnel blinded to the results of the Olfactory Test (blinded study)...

BACKGROUND: Assigning a diagnosis to a patient with dementia is important for the present treatment of the patient and caregivers, and scientific research. Nowadays, the dementia diagnostic criteria are based on clinical information regarding medical, history, physical examination, neuropsychological tests, and supplementary exams and, therefore, subject to variability through time. METHODS: A retrospective observational study to evaluate variables related to clinical diagnostic stability in dementia syndromes in at least one year follow up...

The latent variable "δ" (for "dementia") uniquely explains dementia severity. Depressive symptoms are independent predictors of δ. We explored 115 serum proteins as potential causal mediators of the effect of depressive symptoms on δ in a large, ethnically diverse, longitudinal cohort. All models were adjusted for age, apolipoprotein E, education, ethnicity, gender, hemoglobin A1c, and homocysteine, and replicated in randomly selected 50% subsets. Alpha1-antitrypsin (A1AT), FAS, Heparin-binding EGF-like Growth Factor (HB-EGF), Insulin-like Growth Factor-1 (IGF-1), Luteinizing Hormone (LH), Macrophage Inflammatory Protein type 1 alpha (MIP-1α), Resitin, S100b, Tissue Inhibitor of Metalloproteinase type 1 (TIMP-1), and Vascular Cell Adhesion Molecule type 1 (VCAM-1) each were partial mediators of depression's association with δ...

Endo-ventricular thrombosis represents a possible clinical complication of stress(takotsubo)-cardiomyopathy (SC). Depressed ventricular systolic ventricular function, localized left ventricular (LV) dyskinesis, but also an increased pro-thrombotic state induced by catecholamine surge may facilitate the occurrence of endovascular thrombosis in SC. SC, however, may also present as right ventricular (RV) dysfunction or even as biventricular ballooning. Ventricular thrombosis may therefore theoretically occur in either ventricles or both...

OBJECTIVES: Hypertension, dyslipidemia, diabetes, and obesity are well-established risk factors for cognitive impairment and dementia in older adults. In contrast, previous studies that have assessed the impact of vascular risk factors (VRFs) on cognition in Parkinson's disease (PD) have had methodological limitations and reported conflicting findings. We address this question in a large well-characterized cohort of de novo PD patients. METHODS: A total of 367 untreated and non-demented patients aged 50 years and older with early PD (H&Y = 1...

It is true that a primary goal of diabetes early diagnosis and treatment is quality of life (QoL). The term QoL is still confusing but it is agreed that it composes of four components: The physical component, mental, cogitative component, psychological and social component. Many articles have been written addressing those four components. During the last five years 15500 articles and reviews have been written addressing diabetes and coronary arterial disease, 16100 addressing diabetes and renal function, 28900 addressing diabetes and retinopathy, 16800 addressing diabetic foot ulcers and other 26300 addressing diabetic neuropathy...

INTRODUCTION: The C677T functional variant in the methylene-tetrahydrofolate reductase (MTHFR) gene leads to reduced enzymatic activity and elevated blood levels of homocysteine. Hyperhomocysteinemia has been linked with higher rates of cardiovascular diseases, cognitive decline, and late-life depression. METHODS AND MATERIALS: Here, 3D magnetic resonance imaging data was analyzed from 738 individuals (age: 75.5 ± 6.8 years; 438 men/300 women) including 173 Alzheimer's patients, 359 subjects with mild cognitive impairment, and 206 healthy older adults, scanned as part of the Alzheimer's Disease Neuroimaging Initiative (ADNI)...

Background/Objective: studies on the association of dementia with specific body composition (BC) components are scarce. Our aim was to investigate associations of BC measures with different levels of cognitive function in late-life. Methods: we studied 5,169 participants (mean age 76 years, 42.9% men) in the AGES-Reykjavik Study of whom 485 (9.4%) were diagnosed with mild cognitive impairment (MCI) and 307 (5.9%) with dementia. Visceral fat, abdominal and thigh subcutaneous fat, and thigh muscle were assessed by computed tomography...

Patients suffering from cognitive decline such as mild cognitive impairment or neurodegenerative disorders including Alzheimer's dementia, vascular dementia, frontotemporal dementia, and Lewy body dementia are often accompanied by symptoms like psychosis, depression, agitation, and apathy. Aging increases not only the prevalence of dementia but also the development of kidney disorders, which had emerged as possible risk factor of cognitive impairment and dementia. However, a contribution of renal dysfunction to psychosis associated with cognitive decline remains to be investigated...

BACKGROUND: Hypertension is a risk factor for cerebrovascular disease and cognitive impairment. Women with hypertensive episodes during pregnancy report variable neurocognitive changes within the first decade following the affected pregnancy. However, long-term follow-up of these women into their postmenopausal years has not been conducted. OBJECTIVE: The aim of this study was to examine whether women with a history of preeclampsia were at increased risk of cognitive decline 35-40 years after the affected pregnancy...

Syphilis is a generally sexually transmitted and multisystem disease caused by the spirochete Treponema pallidum. All of the organs of the body may be involved during the course of the disease. Neurosyphilis is a clinical form of syphilis with the central nervous system (CNS) involvement. While primarily meningeal and vascular structures are involved in early neurosyphilis, a parenchymal affection of the brain and spinal cord emerges at later stages of neurosyphilis. It presents with symptoms of meningitis, meningovasculitis and parenchymal neurosyphilis (presenting as tabes dorsalis and general paresis)...

Migraine is a complex, debilitating neurovascular disorder, typically characterized by recurring, incapacitating attacks of severe headache often accompanied by nausea and neurological disturbances. It has a strong genetic basis demonstrated by rare migraine disorders caused by mutations in single genes (monogenic), as well as familial clustering of common migraine which is associated with polymorphisms in many genes (polygenic). Hemiplegic migraine is a dominantly inherited, severe form of migraine with associated motor weakness...

About 20-25% of all persons and about 90% of all patients who are acutely hospitalized in internal medicine departments have multiple acute or chronic diseases. They are multimorbid. The encounter with multimorbid patients has become the most common situation in the health care system. Theoretically, multimorbidity results in an innumerable potential disease constellations. In addition, the likelihood of interactions between diseases (disease-disease interactions, DDI) and the complexity increases overproportionately with each additional disease...

BACKGROUND/AIMS: Neuropsychiatric symptoms (NPS) are common in Alzheimer disease (AD) and vascular dementia (VaD), and are distressful to patients and caregivers. NPS are likely related to the underlying pathology. Previous studies suggest that frontal lobe lesions and vascular changes such as white matter hyperintensities (WMH) have a significant association with specific NPS. The current study aimed to compare NPS in patients with AD, VaD, and mixed AD/VaD, and to evaluate the differences in the prevalence of NPS in relation to frontal WMH volume...

Objective: To determine how pre-stroke cognitive impairment can be detected, its mechanism, and influence on outcome and management. Methods: Literature search. Results: (i) A systematic approach with the Informant Questionnaire of Cognitive Decline in the Elderly is recommended; (ii) Pre-stroke cognitive impairment may be due to brain lesions of vascular, degenerative, or mixed origin; (iii) Patients with pre-stroke dementia, have worse outcomes, more seizures, delirium, and depression, and higher mortality rates; they often need to be institutionalised after their stroke; (iv) Although the safety profile of treatment is not as good as that of cognitively normal patients, the risk:benefit ratio is in favour of treating these patients like others...

Depressive disorders in elderly persons are frequent and can either first be manifested at a younger age and show a recurrent pattern during later life (ICD 10, F33.*) or have an onset beyond 60 years, which is termed late onset depression (LOD). This LOD has a higher tendency to chronification and implies an increased risk of progression, especially to vascular dementia. The multifactorial genesis of depression in old age includes psychosocial, vascular and metabolic factors and requires multimodal therapy modules at the biological and psychosocial level, which is now increasingly being empirically proven...

Post-stroke dementia (PSD) or post-stroke cognitive impairment (PSCI) may affect up to one third of stroke survivors. Various definitions of PSCI and PSD have been described. We propose PSD as a label for any dementia following stroke in temporal relation. Various tools are available to screen and assess cognition, with few PSD-specific instruments. Choice will depend on purpose of assessment, with differing instruments needed for brief screening (e.g., Montreal Cognitive Assessment) or diagnostic formulation (e...
