Mutations in WDR45 are responsible for beta-propeller protein-associated neurodegeneration (BPAN), which is an X-linked form of neurodegeneration with brain iron accumulation. BPAN mainly affects females and is characterized by seizures and developmental delay or intellectual disability until adolescence or early adulthood, followed by severe dystonia, parkinsonism, and progressive dementia. However, rare male patients have recently been reported with hemizygous germline mutations in WDR45 and severe clinical manifestations, such as epileptic encephalopathies...

Interthalamic adhesion thickness has been previously described as a parameter for quantifying canine brain atrophy and hypothesized to correlate with brain height or ventricular size. However, studies testing this hypothesis are lacking. This retrospective cross-sectional study aimed to compare interthalamic adhesion thickness, interthalamic adhesion thickness/brain height ratio, and interthalamic adhesion thickness/brain height ratio/lateral ventricle to brain height ratio values in dogs with and without cognitive dysfunction...

BACKGROUND: The positive effect of human cystatin C on the development of Alzheimer's disease has been reported, as it inhibits the formation of β-amyloid oligomers and amyloidogenesis. Cystatin C has been found to have a neuroprotective effect through inhibiting cysteine proteases, inducing autophagy and neurogenesis. There is a growing interest in the procognitive properties of colostrum-based specimens, which could delay dementia and ameliorate memory deterioration. OBJECTIVES: The aim of the study was to evaluate the influence of Ovocystatin and a Coloco peptide complex on the cognitive functions in reference to Colostrinin, using a model of young and old rats...

BACKGROUND/AIMS: To examine the influence of age on neuropsychological performances in dementia with Lewy bodies (DLB) and Alzheimer disease (AD) patients. METHODS: We examined memory, executive, and visuo-constructional performances in 202 DLB patients and 236 AD patients. We divided the subjects into three age groups (65-74, 75-84, and 85-95 years old), and evaluated the differences in neuropsychological performances. RESULTS: Recent memory in the DLB group was significantly better than that in the age-matched AD group when comparing the age groups 65-74 years and 75-84 years; however, memory impairment in the DLB patients in the age group 85-95 years was comparable with that in the age-matched AD patients...

ANT1 is one of the nuclear genes responsible of autosomal dominant progressive external ophthalmoplegia (adPEO) with mitochondrial DNA multiple deletions. The course of ANT1- related adPEO is relatively benign, symptoms being generally restricted to skeletal muscle. Here we report the case of an Italian 74 years old woman with ANT1-related adPEO and dementia. Further studies are needed to assess the prevalence of central neurological manifestations in ANT1 mitochondrial disease.

Alzheimer's disease (AD) is a single major cause of dementia in middle to old age individuals involving several different etiopathological mechanisms that are yet to be properly characterized. Major invariant and characteristic features consist of the progressive cerebral deposition of the amyloid β-protein (Aβ) and the neurofibrillary degeneration through neurofibrillary tangles (NFT) formed by hyperphosphorylation of the tau proteins in the regions of the brain that deal with memory and cognition. There are at least five subgroups of AD that can be identified by determining cerebro-spinal fluid (CSF) levels of Aβ1-42, tau and ubiquitin...

It is well known that the survival is higher in women compared to men and women have a better survival prognosis than men in some pathologies such as vascular dementia (VD). Our previous reports showed that the spontaneously hypertensive (SH) rat, an animal model of VD, exhibited dendritic atrophy of pyramidal neurons of the dorsal hippocampus (DH) and the prefrontal cortex (PFC) at 8 months of age. Cerebrolysin (CBL), a neurotrophic peptide mixture, reduces dendritic atrophy and improves the memory process in aged rats...

Here we present an autopsy case of chronic traumatic encephalopathy (CTE) in a 36-year-old man. He had a history of febrile seizures at the age of four and was severely demented at age 10 when he was admitted to a mental hospital. He had suffered repetitive self-harm, such as frequent banging of the head on the wall in his hospital record, but he had no clear history between the ages of four and ten. Autopsy revealed global cerebral atrophy, including the basal ganglia, thalamus, hippocampus, amygdala, mammilary bodies and lateral geniculate bodies...

BACKGROUND: Alpha-synuclein (α-syn) aggregation represents the pathological hallmark of α-synucleinopathies like Parkinson's disease (PD), dementia with Lewy bodies (DLB), and multiple system atrophy (MSA). Toll-like receptors (TLRs) are a family of highly conserved molecules that recognize pathogen-associated molecular patterns and define the innate immunity response. It was previously shown that TLR4 plays a role in the clearance of α-syn, suggesting that TLR4 up-regulation in microglia may be a natural mechanism to improve the clearance of α-syn...
