Iron and Amyloid: Correlations to Entorhinal Cortex Degeneration

       Research into the prevention and treatment of Alzheimer’s disease (AD) frequently starts small, with the discovery of risk factors that correlate with elevated deposition of AD biomarkers: amyloid (Aꞵ) plaques and neurofibrillary tangles (NFTs). Recently, researchers observed one such phenomenon involving the build-up of iron in the brain and the localization of […]

Anti-Depressant Drugs and Alzheimer’s: A Surprising Relationship

       Most of our blogs emphasize treatments that directly affect the mechanisms that induce Alzheimer’s disease (AD). However, recent research into the use of anti-depressant drugs and their relationship to AD has provided some interesting results. Namely, administration of escitalopram seems to reduce deposition of amyloid-ꞵ42, which could, in theory, slow the onset […]

A New Investigational Approach to Clinical AD Treatment: ATH-1017

       Alzheimer’s disease (AD) has long eluded a cure, causing researchers to delve deeper into the biological underpinnings of the disorder for new, inventive, and multi-factorial strategies to reduce neurodegeneration before and after onset. One investigational treatment provided by Athira, called ATH-1017, recently began Phase II clinical trial enrollment with our clinic. If […]

LATE and AD: Clinical Interactions

       Most neurological disorders are associated with a biomarker, a protein or biological by-product whose concentration correlates to the development of the disorder. AD’s biomarkers, as you may already know, are amyloid-beta (Aꞵ) precipitated as plaques and misfolded tau protein that forms neurofibrillary tangles (NFTs). Another common biomarker of neurological disorders is TAR […]

What Are Coarse-Grained Plaques?

       Alzheimer’s disease (AD) was identified in 1901 by Alois Alzheimer but despite being known for over a century, researchers are discovering new things about the disease today. For example, our regular readers should be familiar with the term “amyloid plaques” which are likely the most well researched biomarkers of AD. There are […]

Cognitive Resilience: Developmental Vs. Genetic Factors

       A recent discovery of a genetically unique family has shown that developmental disorders may predispose or change the presentation of Alzheimer’s disease (AD) dementia. The family studied consisted of 10 siblings, 8 of whom presented with developmental language problems and 1 with a sub-syndrome of frontotemporal dementia known as logopenic variant primary […]

Insulin and AD

        Insulin is typically associated with regulating blood glucose levels and diabetes, but it also serves as a crucial signaling molecule throughout the body, including the central nervous system (CNS). In fact, there is evidence that insulin may play a role in the development of Alzheimer’s disease (AD) and Mild Cognitive Impairment […]

Learning Impairment in Preclinical AD

       Memory impairment is often the hallmark symptom of Alzheimer’s disease (AD). However, research recently discovered a trend suggesting that decreased learning may preface memory loss in the preclinical phase of AD. Amyloid-positive patients in the preclinical stage of AD first experience a decline in learning ability while their memory is still comparable […]

New Discovery in Tau Pathology

      We frequently discuss what factors increase or reduce risk for Alzheimer’s disease (AD) and other memory-impairing disorders. However, with research constantly ongoing there is always more to learn. Recently, researchers discovered an important impact of misfolded tau protein in rat brains with AD that sheds some light on how tau increases risk, […]

What is Hippocampal Sclerosis?

   Today we will discuss Hippocampal Sclerosis (HS), which causes memory impairment similar to, and frequently confused as, Alzheimer’s disease (AD). HS is often misdiagnosed as AD because initial symptoms and rate of progression follow roughly the same pattern, but as the neurodegeneration continues the two disorders diverge. Memory impairment is severe in both HS […]
