Alzheimers Dement
December 2024
Critical Path for Alzheimer's Disease (CPAD) Consortium, Critical Path institute, Tucson, AZ, USA.
Background: To help improve the Alzheimer's disease (AD) therapeutics research and development process, the Critical Path for Alzheimer's Disease (CPAD) Consortium at the Critical Path Institute (C-Path) provides a neutral framework for the drug development industry, regulatory agencies, academia, and patient advocacy organizations to collaborate. CPAD's extensive track record of developing regulatory-grade quantitative drug development tools motivates sponsors to share patient-level data and neuroimages from clinical trials. CPAD leverages these data and uses C-Path's core competencies in data management and standardization, quantitative modeling, and regulatory science to develop tools that help de-risk decision making in AD drug development.

Alzheimers Dement
December 2024
Indiana University School of Medicine, Indianapolis, IN, USA.
Background: SHIP1 is a phosphatidyl inositol phosphatase encoded by INPP5D, which has been identified as a risk gene for Alzheimer's disease (AD). SHIP1 is expressed in microglia, the resident macrophage in brain. It is a complex, multidomain protein that acts as a negative regulator downstream from TREM2.

Alzheimers Dement
December 2024
Indiana University School of Medicine, Indianapolis, IN, USA.
Background: The goal of the TREAT-AD Center is to enable drug discovery by developing assays and providing tool compounds for novel and emerging targets. The role of microglia in neuroinflammation has been implicated in the pathogenesis of Alzheimer's disease (AD). Genome-wide association studies, whole genome sequencing, and gene-expression network analyses comparing normal to AD brain have identified risk and protective variants in genes essential to microglial function.

Washington University in St. Louis, School of Medicine, St. Louis, MO, USA; Washington University School of Medicine, St. Louis, MO, USA; Knight Alzheimer Disease Research Center, St. Louis, MO, USA.
Although amyloid b immunotherapies offer great potential for prevention or delay of symptoms in dominantly inherited AD (DIAD), the mechanism of action of this class of medications does not address the underlying mechanism of most DIAD mutations. Moreover, the need for repeated IV infusions or sub-cutaneous injections with Ab immunotherapies may prove challenging for long-term prevention approaches. The majority of DIAD mutations appear to affect the interaction of the gamma-secretase enzyme with the Amyloid Precursor Protein (APP) making this enzyme an attractive target for disease modification.

Alzheimers Dement
December 2024
Prevent Alzheimer's Disease 2020, Inc., Rockville, MD, USA.
Background: Disparities in the quality and timeliness of care for Alzheimer's disease (AD) are well documented. This study assessed the impact of demographic characteristics on the diagnosis and management of early AD patients in community-based settings.
Method: This cross-sectional study abstracted medical chart data for patients aged 50-89 years who had newly diagnosed early AD (mild cognitive impairment [MCI] or mild AD) within the past 2 years and a clinic visit within the past 12 months.
