Intact cross-modality text-specific repetition priming in patients with Alzheimer’s disease

2001

This study was aimed at investigating the basic mechanisms of the normal repetition priming evoked by text re-reading procedures in Alzheimer's disease (AD) patients (Monti, Gabrieli, Wilson, & Reminger, 1994; Monti et al., 1997). For this purpose, we contrasted the reading facilitation elicited by previous reading or listening to a text in a sample of AD patients and a group of age-matched normal controls. Consistent with previous evidence in normal undergraduates (Levy & Kirsner, 1989), previous listening to a text decreased the successive reading time of the same text (cross-modality priming). However, the reading facilitation elicited by previous reading of the same text (within…

When the amnestic mild cognitive impairment disappears: characterisation of the memory profile

2009

BACKGROUND/OBJECTIVES: Subjects affected by mild cognitive impairment (MCI) may improve during the observation period. This is the first study investigating qualitative features of memory deficits in subjects affected by reversible MCI [reversible cognitive impairment (RCI)]. METHODS: Baseline cognitive and memory performances of 18 subjects affected by amnestic MCI who had normalized cognitive performances at follow-ups were compared with those of 76 amnestic MCI subjects who still showed impaired cognitive performances at the 24-month follow-up (MCI) and with those of a group of 87 matched control subjects (normal controls). RESULTS: Compared with normal controls the memory deficit in the…

Thioflavin T templates amyloid β(1–40) conformation and aggregation pathway

2015

Aβ(1-40) peptide supramolecular assembly and fibril formation processes are widely recognized to have direct implications in the progression of Alzheimer's disease. The molecular basis of this biological process is still unknown and there is a strong need of developing effective strategies to control the occurring events. To this purpose the exploitation of small molecules interacting with Aβ aggregation represents one of the possible routes. Moreover, the use specific labeling has represented so far one of the most common and effective methods to investigate such a process. This possibility in turn rests on the reliability of the probe/labels involved. Here we present evidences of the effe…

(±)- BIGI-3h: Pentatarget-Directed Ligand combining Cholinesterase, Monoamine Oxidase, and Glycogen Synthase Kinase 3β Inhibition with Calcium Channe…

2021

Multitarget-directed ligands (MTDLs) are considered a promising therapeutic strategy to address the multifactorial nature of Alzheimer's disease (AD). Novel MTDLs have been designed as inhibitors of human acetylcholinesterases/butyrylcholinesterases, monoamine oxidase A/B, and glycogen synthase kinase 3β and as calcium channel antagonists via the Biginelli multicomponent reaction. Among these MTDLs, (±)-BIGI-3h was identified as a promising new hit compound showing in vitro balanced activities toward the aforementioned recognized AD targets. Additional in vitro studies demonstrated antioxidant effects and brain penetration, along with the ability to inhibit the aggregation of both τ protein…

Serum alkaline phosphatase is elevated and inversely correlated with cognitive functions in subjective cognitive decline: results from the ReGAl 2.0 …

2020

Background: Alkaline phosphatase has been found on neuronal membranes and plasma alkaline phosphatase (ALP) activity increases during brain injury and cerebrovascular diseases, suggesting that its levels may reflect the neuronal loss. It is known that ALP is higher in subjects affected by Alzheimer’s dementia and inversely correlated with cognitive functions. No study has investigated the relationship between ALP and cognitive functions in old-age subject with pre-clinical cognitive impairment. Methods: This is a cross-sectional study with data gathered from the ReGAl 2.0 project (Rete Geriatrica Alzheimer-Geriatric Network on Alzheimer’s disease), a large Italian multicentric clinical-base…
