BACKGROUND Recently described neuronal intermediate filament inclusion disease (NIFID) shows considerable clinical heterogeneity. OBJECTIVE To assess the spectrum of the clinical and neuropathological features in 10 NIFID cases. METHODS Retrospective chart and comprehensive neuropathological review of these NIFID cases was conducted. RESULTS The mean age at onset was 40.8 (range 23 to 56)...
In order to investigate the sequence and pattern of neurodegeneration in Huntington's disease, the distribution and density of cannabinoid CB(1), dopamine D(1) and D(2), adenosine A(2a) and GABA(A) receptor changes were studied in the basal ganglia in early (grade 0), intermediate (grades 1, 2) and advanced (grade 3) neuropathological grades of Huntington's disease. The results showed a sequent...
Autism is currently viewed as a largely genetically determined neurodevelopmental disorder, although its underlying biological causes remain to be established. In this review, we examine the available neuropathological literature on autism and discuss the findings that have emerged. Classic neuropathological observations are rather consistent with respect to the limbic system (nine of 14 studie...
BACKGROUND Dogs develop spontaneous ischaemic stroke with a clinical picture closely resembling human ischaemic stroke patients. Animal stroke models have been developed, but it has proved difficult to translate results obtained from such models into successful therapeutic strategies in human stroke patients. In order to face this apparent translational gap within stroke research, dogs with isc...
BACKGROUND The interpretation of neuropathological studies of dementia and Alzheimer's disease is complicated by potential selection mechanisms that can drive whether or not a study participant is observed to undergo autopsy. Notwithstanding this, there appears to have been little emphasis placed on potential selection bias in published reports from population-based neuropathological studies of...
Bipolar disorder (BP) traditionally has been considered as a recurrent illness with full recovery between episodes, and the absence of neuropathological abnormalities has usually been taken for granted. In recent times, the realization that, for many BP carries a poor prognosis, that cognitive deficits are often persistent and that structural brain abnormalities are detectable with modern imagi...
Rodent scrapie models have been exploited to define the molecular basis for the progression of neuropathological changes in TSE diseases. We aim to assess whether CNS gene expression changes consistently observed in mouse models are of generic relevance, for example to natural TSE diseases, or are TSE strain, host species or brain region specific. Six genes, representing distinct physiological ...
Anticipating the diagnosis of Alzheimer's Disease (AD) and other dementias depends on seeing such conditions as progressive neuropathological phenomena originating before clinical manifestation...
BACKGROUND Clinicopathological studies are important in determining the brain lesions underlying dementia. Although almost 60% of individuals with dementia live in developing countries, few clinicopathological studies focus on these individuals. We investigated the frequency of neurodegenerative and vascular-related neuropathological lesions in 1,092 Brazilian admixed older adults, their correl...
