Alzheimer’s disease (AD) is the most common dementia type, with no treatment to slow down the progression of this dehumanizing disease currently available. The mechanisms of AD are poorly understood … Continue Reading Astrocytes linked to Alzheimer’s disease for the first time.
Alzheimer’s disease (AD) is a fatal neurodegenerative disorder as well as the leading cause of senile dementia worldwide, with no effective treatment and limited functionality for early diagnosis. Now, a … Continue Reading Noninvasive eye scan can detect key signs of Alzheimer’s Disease in humans.
Alzheimer’s disease (AD) is characterized by cognitive decline, alteration of synaptic transmission, and neuronal death brought on by accumulation of neurofibrillary tangles in neurons and amyloid beta in the brain. … Continue Reading Study shows that vesicles appear to also contribute to Alzheimer’s disease.
Alzheimer’s disease is characterized by the degeneration of neurons in the hippocampus and cortex, and the appearance of neuritic plaques and neurofibrillary tangles. Although the precise cause of Alzheimer’s disease remains … Continue Reading Researchers elevate brain protein to allay symptoms of Alzheimer’s in animal model.
Neurodegeneration in Alzheimer’s disease is thought to be caused by the abnormal behavior of amyloid-beta molecules, which are known to gather into tough fibril-like structures called amyloid plaques within patients’ … Continue Reading Human amyloid-beta shown to act as a powerful antibiotic in the brains of animal models.
In Alzheimer’s, a build-up of plaque and dysfunctional proteins in the brain are known to be hallmarks of the disease. While the majority of Alzheimer’s research has focused on accumulation … Continue Reading New technique reveals that tau predicts Alzheimer’s disease progression.
Amyloidosis is a general term for several different types of disease. Aggregates of amyloid proteins form and deposit in different tissues which can affect the normal function. As the disease … Continue Reading Towards a new sensitive method for the early detection of amyloidosis.
A major problem of Alzheimer’s disease diagnosis is by the time the first clinical symptoms appear, massive irreversible damage to the brain has already occurred. At that point, symptomatic treatment … Continue Reading New infrared sensor extracts amlyloid-beta from blood for early detection of Alzheimer’s.
Dendritic spines are specialized protrusions responsible for receiving excitatory synaptic inputs, providing an important function in communication between neurons. The majority of excitatory synapses in the brain exist on dendritic … Continue Reading Novel molecule promotes the neuronal structures associated with memory to grow.
Primary progressive aphasia (PPA) is a form of dementia characterized by degeneration of the language network. In the early stages, PPA is associated with a left-lateralized pattern of cortical atrophy … Continue Reading Neuroimaging can identify start and location of amyloid plaques in living brain.
With Alzheimer’s disease medical professionals have to conduct costly brain imaging scans, and sometimes, invasive cerebral spinal fluid tests to rule out other diseases. Now, a new study from researchers … Continue Reading Human study identifies biomarker in blood for Alzheimer’s disease.
Alzheimer’s disease poses a health problem of pandemic proportions. It is estimated that by the year 2030 there will be greater than 60 million people worldwide with AD, and $375 … Continue Reading Newly identified role for ApoE explains its effects in Alzheimer’s.
The standard model of natural selection predicts that once the age of reproduction ends, individuals die. That’s because selection early in life strongly favors variants that benefit reproductive success, even … Continue Reading Study identifies gene variants which protect older adults from neurodegeneration.
Down syndrome (DS) results from the trisomy of chromosome 21 in humans and is the most common cause of genetically defined intellectual disability. Among the various triplicate genes in DS … Continue Reading Study identifies new link between Down syndrome and Alzheimer’s disease.
Biomarkers, such as those sought for Alzheimer’s disease, are benchmarks in the body that can be reliably measured to indicate the presence or absence of a disease, or the likelihood … Continue Reading Earliest-ever diagnosing tool for Alzheimer’s becomes international standard.
Worldwide, more than 20% of persons over the age of 85 suffer from Alzheimer’s disease. Deposits of beta-amyloid (Aβ) peptide represent an important target for research into Alzheimer’s disease. These … Continue Reading Researchers take a step towards utilising the brain’s microglia to fight Alzheimer’s disease.
