The Texas sisters with childhood Alzheimer's

Both Abby, three, and Belle, seven, have Niemann-Pick Type C1, a genetic disease where in time, children slowly regress until they can ’t walk, eat, and dementia will set in before age 10.

CONCLUSION: Our findings suggest that although MCI subjects showed similar behavioral phenotypes at the time of diagnosis, EF and further progression were associated with different brain regions according to Aβ burden. Clarification of the etiologies and nature of EF impairment in aMCI are critical for disease prognosis and management. PMID: 31538428 [PubMed - in process]

Publication date: Available online 21 September 2019Source: Progress in NeurobiologyAuthor(s): Lindsey D. Goodman, Nancy M. BoniniABSTRACTMany human diseases are associated with the expansion of repeat sequences within the genes. It has become clear that expressed disease transcripts bearing such long repeats can undergo translation, even in the absence of a canonical AUG start codon. Termed “RAN translation” for repeat associated non-AUG translation, this process is becoming increasingly prominent as a contributor to these disorders. Here we discuss mechanisms and variables that impact translation of the repea...

Photo credit Sharon McCutcheon Dear Carol: My 71-year-old mother is slender, a non-smoker, socially active, and gets a decent amount of exercise. She takes three medications that I know of. While she has an occasional “gap out” with a word here and there, that seems like normal aging. What troubles me is that she’s increasingly paranoid about other people doing things to her. When she forgets where she put something, she’s sure someone moved it or took it. If she has a car problem, she insists that someone sabotaged it. I try to ease her mind by joking about her suspicions but she won...

This study underscores the importance of chronic stimulation in the modulation of sensorimotor integration and proprioception. The authors considered two possible mechanisms underlying SAI modulation by STN DBS. High-frequency DBS of the STN might normalize synchronization between basal ganglia structures, which might restore the ability of thalamocortical relay cells to respond to depolarizing inputs involved in sensorimotor integration (Brown et al., 2001; Rubin and Terman, 2004). Alternatively, STN DBS might have a direct effect on cortical structures through antidromic stimulation of the cortico-subthalamic pathway. I...

Hydroxypropyl-β-cyclodextrin formulated in nasal chitosan microspheres as candidate therapeutic agent in Alzheimer's disease. Curr Drug Deliv. 2017 Oct 19;: Authors: Rassu G, Gavini E, Carta A, Obinu A, Porcu EP, Giunchedi P Abstract Hydroxypropyl-β-cyclodextrin (HP-CD) is a hydroxyalkyl derivative of native β-cyclodextrin, cyclic oligosaccharide able to form inclusion complexes with many drugs and biomolecules [1]. Cyclodextrins have a possible neuroprotective effect due to their capability to extract and deplete cholesterol from cell membranes [1]. HP-CD is classified as an excipient ...

Abstract Trisomy 21 and the consequent extra copy of the amyloid precursor protein (APP) gene and increased beta-amyloid (Aβ) peptide production underlie the universal development of Alzheimer's disease (AD) pathology and high risk of AD dementia in people with Down syndrome (DS). Trisomy 21 and other forms of aneuploidy also arise among neurons and peripheral cells in both sporadic and familial AD and in mouse and cell models thereof, reinforcing the conclusion that AD and DS are two sides of the same coin. The demonstration that 90% of the neurodegeneration in AD can be attributed to the selective loss of a...
