Modeling the association between 43 different clinical and pathological variables and the severity of cognitive impairment in a large autopsy cohort of elderly persons. Brain Pathol. 2010;20:66-79 pubmed publisher..There was no support for independent association between CILA severity and most evaluated indices including diffuse plaques, argyrophilic grains, heart disease, education level, apolipoprotein E alleles or diabetes. ..

Acta Neuropathol. 2016;132:841-858 pubmed..We conclude that brain thyroid hormone perturbation is a potential pathogenetic factor in HS that may also provide the basis for a novel CSF-based clinical biomarker. ..

J Cereb Blood Flow Metab. 2017;37:201-216 pubmed..We conclude that brain arteriolosclerosis is associated with altered cognitive status and a novel vascular genetic risk factor. ..

Acta Neuropathol. 2014;127:825-43 pubmed publisher..Controlling for important confounders such as diabetes itself, exposure to a sulfonylurea drug was associated with risk for HS-Aging pathology (p = 0.03). Thus, we describe a novel and targetable dementia risk factor. ..
- Scheff S, Neltner J, Nelson P. Is synaptic loss a unique hallmark of Alzheimer's disease?. Biochem Pharmacol. 2014;88:517-28 pubmed publisher..These findings indicate that synapse loss is probably not a hallmark specific to AD but rather a change common to many diseases associated with dementia. ..

This phenomenon may help guide medical practice including clinical trial study design. ..

Adjusted miR-107 and BACE1 mRNA levels tended to correlate negatively (trend with regression P< 0.07). In sum, miR-107 expression tends to be lower relative to other miRNAs as AD progresses. ..

Genomics Proteomics Bioinformatics. 2014;12:19-30 pubmed publisher..In summary, we provide a detailed study of the tissue and cell type-specific expression profile of this highly expressed and phylogenetically conserved family of miRNA genes. ..

Acta Neuropathol. 2013;126:161-77 pubmed publisher..We conclude that the published literature on HS-Aging provides strong evidence of an important and under-appreciated brain disease of aging. Unfortunately, there is no therapy or preventive strategy currently available...

J Neuropathol Exp Neurol. 2012;71:362-81 pubmed publisher..Although A? plaques may play a key role in AD pathogenesis, the severity of cognitive impairment correlates best with the burden of neocortical neurofibrillary tangles. ..

Brain. 2011;134:1506-18 pubmed publisher..In summary, in the largest series of autopsy-verified patients with hippocampal sclerosis to date, we characterized the clinical and pathological features associated with hippocampal sclerosis associated with ageing. ..

Acta Neuropathol. 2011;121:571-87 pubmed publisher..In conclusion, it may be most fruitful to focus attention on specific pathways involved in AD rather than attributing it to an inevitable consequence of aging. ..
- Nelson P, Braak H, Markesbery W. Neuropathology and cognitive impairment in Alzheimer disease: a complex but coherent relationship. J Neuropathol Exp Neurol. 2009;68:1-14 pubmed publisher..We argue that existing data strongly support the hypothesis that both amyloid plaques and NFTs contribute to cognitive impairment. ..

Alzheimer's-type neuropathology in the precuneus is not increased relative to other areas of neocortex across a range of cognitive impairment. Neurosci Lett. 2009;450:336-9 pubmed publisher..Our results are not consistent with the idea that the precuneus is involved in a special way with plaques or tangles relative to other areas of neocortex. ..
