Olfactory Impairment and Incident Cognitive Decline: A Systematic Review and Meta‐Analysis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory impairment (OI) is associated with poor ageing outcomes. While cross‐sectional studies found a high prevalence of OI among patients with neurodegenerative diseases, the temporal relationship remains unclear. This meta‐analysis aims to synthesise the longitudinal association of OI with cognitive decline (CD). Methods PubMed,

Blood α‐Synuclein Separates Parkinson's Disease from Dementia with Lewy Bodies

Annals of Neurology, EarlyView.
Objective Aggregation of misfolded α‐synuclein (aSyn) within the brain is the pathologic hallmark of Lewy body diseases (LBDs), including Parkinson's disease (PD), and dementia with Lewy bodies (DLB) disease. Although evidence exists for aSyn “strains,” conformations with distinct biological properties, biomarkers for PD versus DLB are lacking.

Multimodal FMRI resting-state functional connectivity in granulin mutations: the case of fronto-parietal dementia. [PDF]

PLoS ONE, 2014
BACKGROUND: Monogenic dementias represent a great opportunity to trace disease progression from preclinical to symptomatic stages. Frontotemporal Dementia related to Granulin (GRN) mutations presents a specific framework of brain damage, involving fronto-

Non-verbal episodic memory deficits in primary progressive aphasias are highly predictive of underlying amyloid pathology [PDF]

, 2016
Diagnostic distinction of primary progressive aphasias (PPA) remains challenging, in particular for the logopenic (lvPPA) and nonfluent/agrammatic (naPPA) variants.

TARDBP (TDP‐43) Knock‐in Zebrafish Display a Late‐Onset Motor Phenotype and Loss of Large Spinal Cord Motor Neurons

Annals of Neurology, EarlyView.
Objective Mutations in TARDBP (encoding TDP‐43) are associated with the neurodegenerative disease amyotrophic lateral sclerosis (ALS) and include familial missense mutations where there are a lack of models and mechanisms examining how they are pathogenic.

Basal parasympathetic deficits in C9orf72 hexanucleotide repeat expansion carriers relate to smaller frontoinsula and thalamus volume and lower empathy

NeuroImage: Clinical
Diminished basal parasympathetic nervous system activity is a feature of frontotemporal dementia that relates to left frontoinsula dysfunction and empathy impairment.

Evaluating combinations of diagnostic tests to discriminate different dementia types

Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, 2018
Introduction We studied, using a data‐driven approach, how different combinations of diagnostic tests contribute to the differential diagnosis of dementia.

Early affective changes and increased connectivity in preclinical Alzheimer's disease. [PDF]

, 2018
IntroductionAffective changes precede cognitive decline in mild Alzheimer's disease and may relate to increased connectivity in a "salience network" attuned to emotionally significant stimuli.

Buried Treasure? Overlooked and Newly Discovered Evolutionary Contributions to Human Brain Diseases

Annals of Neurology, EarlyView.
Recapitulative schema of different exploratory levels of the evolutionary impact on human neurological diseases. Clinical neuroscience focuses on the mechanisms of brain function, but this approach falls short of insights into how the central nervous system (CNS) evolved, both in health and disease.

Examining the propensity and nature of criminal risk behaviours in frontotemporal dementia syndromes and Alzheimer's disease

Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring
INTRODUCTION Some people with dementia develop changes in behaviour and cognition that may lead to interactions with police or the legal system. However, large, prospective case–control studies examining these behaviours are lacking.
