Alzheimers Dement
December 2024
Edith Cowan University, Perth, Western Australia, Australia.
Background: Accumulation of amyloid beta 42 (Aβ42) senile plaques is the most critical event leading to Alzheimer's disease (AD). Currently approved drugs for AD have not been able to effectively modify the disease. This has caused increasing research interests in health beneficial nutritious plant foods as viable alternative therapy to prevent or manage AD.

Alzheimers Dement
December 2024
Yonsei University, Incheon, Incheon, Korea, Republic of (South).
Background: As amyloid-β (Aβ) aggregates are considered as the biomarkers and key factors in the pathology of Alzheimer's disease, there has been extensive investigation into Aβ-targeting compounds for the development of diagnostics and drug discovery related to the disorder. However, the polymorphic and heterogenous nature of Aβ aggregates impedes the structural understanding of their structure. Consequently it is a major challenge to develop new diagnostic and therapeutic development of AD and to study the mechanism of Aβ-targeting compounds.

SORL1 encodes an endosomal trafficking receptor, SORLA, which regulates endosomal protein recycling through its interaction with the retromer core complex (consisting of VPS26, VPS35 and VPS29). Deficits in the levels and function of the SORLA-retromer complex are thought to underlie AD.

Alzheimers Dement
December 2024
Olabisi Onabanjo University, Sagamu, Ogun, Nigeria.
Background: Alzheimer's disease is a neurodegenerative disease associated with the accumulation of amyloid beta proteins to form plaques and the aggregation of hyperphosphorylated tau to form neurofibrillary tangles. Human fibroblast (SH-SY5Y) cells endogenously express Tau, and the expression is further amplified upon differentiation into neuronal cells, making it a cell model of Alzheimer's disease. Nigella sativa oil (NSO) contains 50% thymoquinone and has been used in the treatment of various nervous system disorders.

Alzheimers Dement
December 2024
Vanderbilt University Medical Center, Nashville, TN, USA.
Background: We report the case of a 79-year-old woman with Alzheimer's disease who enrolled in a clinical study of lecanemab. After the third, biweekly infusion she suffered a seizure followed by aphasia and progressive encephalopathy. Magnetic resonance imaging revealed multifocal cerebral edema and an increased burden of cerebral microhemorrhages compared to pre-trial imaging.
