Iron build-up in the brain linked to age-related cognitive decline

February 3, 2022

The accumulation or iron in the brains of aging organisms is said to contribute to neurodegenerative diseases including Alzheimer’s disease. According to researchers at Northwestern University Feinberg School of Medicine (Northwestern), treatment with drugs called iron chelators could combat neurodegenerative diseases and restore normal iron metabolism in those experiencing high iron levels. In a study […]

Brain fog from mild COVID linked to lingering inflammation

February 1, 2022

An after-effect of COVID-19 (COVID), brain fog has been reported in over 65% of patients at a post COVID clinic in New York – suspected due to brain inflammation, as well as the presence of unexpected antibodies found in an activated immune system. Researchers from the University of California, San Francisco (UCSF), further confirm this […]

Cholesterol manufactured in the brain key to development of Alzheimer’s

September 15, 2021

Cholesterol produced by cells called astrocytes is required for controlling the production of amyloid beta, a sticky protein that builds up in the brains of patients with Alzheimer’s disease (Alzheimer’s), scientists have found. Not only associated with clogged arteries and heart disease, cholesterol is also made naturally by the body to produce hormones and carry […]

Brain metabolism cause of neurodegeneration in Alzheimer’s disease

July 27, 2021

Alzheimer’s Disease (AD), the most common type of dementia, causes the death of neurons and leads to shrinking of the brain. Patients with AD will eventually experience gradual deterioration in memory, thinking, behaviour and the ability to perform everyday activities. Yet, scientists do not fully understand what causes this disease. A recent research, conducted by […]

Enzyme regulation may protect the brain against oxygen deprivation damage

May 27, 2021

Researchers at Massachusetts General Hospital (MGH), US, have identified an enzyme that may be a potential therapeutic target to protect the brain from oxygen deprivation damage, or hypoxia. Severe hypoxia may cause devastating side effects from a stroke or heart attack due to either tissue or brain damage. In this study, the researchers set out […]

New 3D MRI technique offers better diagnostic capabilities

May 10, 2021

A new imaging technique developed by researchers at Mātai Medical Research Institute, New Zealand, offers unrivaled spatial resolution in three dimensions (3D), and allows for visualisation of motion in the brain at an unprecedented level of detail. An innovative imaging technique was introduced previously called amplified magnetic resonance imaging (aMRI) that allowed researchers and clinicians […]

Neuroscientists discover how brain recognizes speech in a noisy room

December 30, 2016

A common festive phenomenon that is of interest to researchers who are seeking to improve speech recognition technology is something that is called the “cocktail party effect”. It is the ability to focus one’s listening attention to a specific conversation or a single speaker while filtering out a range of other conversations and background noise. […]
