Magnetic resonance imaging in dementia.

CONCLUSION: Today the role of MRI is no longer limited to ruling out underlying causes of cognitive deterioration. MRI can show patterns of atrophy with a predictive value for certain dementias which, although not specific or unique to each disease, can help to confirm diagnostic suspicion or to identify certain processes. For this reason, it is important for radiologists to know the characteristic findings of the most common dementias. PMID: 29903629 [PubMed - as supplied by publisher]

Authors: Cummings J Abstract Neuropsychiatric syndromes and symptoms play increasingly important roles in research diagnostic criteria for neurodegenerative disorders. Diagnostic criteria were reviewed including those for dementia, Alzheimer's disease, mild cognitive impairment, mild behavioral impairment, prodromal Alzheimer's disease, dementia with Lewy bodies, prodromal dementia with Lewy bodies, Parkinson's disease, multiple system atrophy, frontotemporal dementia, primary progressive aphasia, progressive supranuclear palsy, corticobasal degeneration, traumatic encephalopathy syndrome, Huntington' disease, amyo...

Introduction: Frontotemporal lobar degeneration (FTLD)-related syndrome includes progressive supranuclear palsy (PSP) and corticobasal syndrome (CBS). PSP is usually caused by a tauopathy but can have associated Alzheimer's disease (AD) while CBS can be caused by tauopathy, transactive response DNA binding protein 43 kDa, or AD pathology. Our aim was to compare the parkinsonian syndromes presenting without AD biomarkers (CBS/PSP-non-AD) to parkinsonian syndromes with AD biomarkers (CBS/PSP-AD).Materials and Methods: Twenty-four patients [11 males, 13 females; age (68.46 ± 7.23)] were recruited for this study. The wh...

Conclusion: Alpha-synuclein levels in the CSF can be used for the discrimination between LBD and AD, but not LBD and other neurodegenerative disorders such as dementia in PD, MSA, FTD, and PSP.

Progressive supranuclear palsy is a taupathy disorder often mistaken on diagnosis by other neurocognitive disorders such as Parkinson's (PD) and Alzheimer's (AD) disease amongst other. PSP tends to be diagnosed in the later course of the disease and by time of diagnosis, individuals have a median survival of 7?years. PSP is a disease in which a diagnosis and treatment is done in a multidisiplinary approach involving collaboration of Psychiatry and Neurology. As it was seen in this clinical case which describes a patient with undetected progressive supranuclear palsy who were referred to a university hospital psychiatric em...

Cortical swollen neurons with achromasia, described as ballooned neurons (BNs), are hallmark of neurodegenerative diseases such as Pick body disease, corticobasal degeneration (CBD), progressive supranuclear palsy (PSP), and argyrophilic grain disease (AGD) [1]. BNs are also found less frequently in Alzheimer's disease (AD) and Parkinson's disease (PD), while their role in pathological differentiation remains to be clarified [2]. We experienced an autopsy case with abundant BNs in a 94-year-old man with clinico-pathologically confirmed dementia with Lewy bodies (DLB).

Dynamic behaviors of α-synuclein and tau in the cellular context: New mechanistic insights and therapeutic opportunities in neurodegeneration. Neurobiol Dis. 2019 Jul 24;:104543 Authors: Yeboah F, Kim TE, Bill A, Dettmer U Abstract α-Synuclein (αS) and tau have a lot in common. Dyshomeostasis and aggregation of both proteins is central in the pathogenesis of neurodegenerative diseases: Parkinson's disease, dementia with Lewy bodies, multi-system atrophy and other 'synucleinopathies' in the case of αS; Alzheimer's disease, frontotemporal dementia, progressive supranuclear palsy ...
