Agitation is a common feature in people with dementia. Agitation can be the clinical expression of a medical condition comorbid with dementia or a behavioural and psychological symptom of dementia. In both cases, it is a clinical manifestation and not a disease in itself. This polysemy of agitation invites us to think of a global care of the demented subject taking into account the subject in his environment and their history. Reducing the treatment of agitation to sedating it amounts to a reification of the demented subject.

Background: Heterogeneity in the progression of clinical dementia poses a significant challenge, impeding the effectiveness of current therapies for Alzheimer's disease (AD). To decipher the molecular mechanisms governing heterogeneity in AD progression that remains a critical knowledge gap precluding rational therapeutic design, we investigated the biochemical and biophysical properties of tau present in the inferior temporal gyrus (ITG) and prefrontal cortex (PFC) brain regions of AD patients who had varying disease progression rates. To explore gene expression changes in the ITG which are associated with tau pathology and cognitive decline, we used RNA sequencing for molecular characterization of patients displaying tau and clinical heterogeneity.

Background: Psychosis occurs in 30-40% of individuals with AD. New insights into disease mechanisms may lead to novel pharmacological targets and treatments. Previous studies have focused on bulk tissue analysis with limited results.

Background: Amyloid filaments formation is a complex kinetic and thermodynamic process. The dependence of peptide polymerization on peptide-peptide interactions to form a β-pleated sheet fibrils and the stimulatory influence of other proteins on the reaction suggest that amyloid formation may be subject to modulation METHOD: In vitro formation of β-amyloid was induced by incubation of an aqueous solution of AβP (10 mg/ml) for 7 days at 37°C. The extent of β-amyloid formation and disaggregation were monitored using a panel of well characterized mAbs raised against soluble AβP fragments.

Background: Huntington's disease (HD) is an autosomal dominant condition causing severe neurodegeneration in the striatum and the entorhinal cortex (EC). An epigenome wide association study of DNA methylation in HD by our group, identified potential hypomethylation at the PTGDS gene in the striatum. We aimed to validate this result through pyrosequencing, examining the locus in fine detail, and to assess the signal specificity by profiling multiple neurodegenerative diseases.

Background: Patients with Alzheimer's Disease (AD) frequently manifest comorbid neuropsychiatric symptoms (NPS) with depression and anxiety being most prevalent. Previously we identified shared genetic risk loci between AD and major depressive disorder (MDD). In another study, we constructed a polygenic risk score (PRS) based on MDD-GWAS data and demonstrated its performance in predicting depression onset in LOAD patients.
