A Recently Proposed Model for Alzheimer’s Potentially Unifies 100 Years of Hypotheses

A Recently Proposed Model for Alzheimer’s Potentially Unifies 100 Years of Hypotheses

A new model, proposed by post-doctoral researcher Dr. Jonathan Rudge, offers a novel, compelling explanation for Alzheimer’s disease: The lipid invasion model. Dr. Rudge’s model takes into account many of the hallmarks of Alzheimer’s disease, including not only neurofibrillary tangles and amyloid plaques but the presence of lipids and damage to the blood-brain barrier among others, to describe in great detail how risk factors lead to the damage seen in the brains of people with Alzheimer’s.

Altered Reality: Rare Brain Disorders That Change How You Perceive the World

Most of the time, our brains can show us a picture that matches the physical world. Visual illusions remind us that the brain doesn’t always get it right, filling in the gaps with our past experiences and bending the perception of reality to meet our expectations. This offers room for translation errors, genetic missteps, and the opportunity for peculiar side effects in how we experience the world around us.

Storytelling and Pain Relief

Scientists have long wondered what the purpose of imagination and pretend-play serves on an evolutionary basis. Humans seem to be hard-wired to create and appreciate stories, whether factual or fictitious, but its evolutionary purpose has eluded us. How do stories and make-believe help us survive the world around us?

Nature vs. Nurture: Scientific Models and Their Importance to Neurological Conditions

Nature vs. Nurture: Scientific Models and Their Importance to Neurological Conditions

Scientific models are useful scientific tools to reduce complex phenomena into more simplistic terms. One such example is the nature versus nurture debate, which asks whether it’s our innate genes or our environment that defines who we are. This debate has since ended for the most part but it serves as an important example as to how scientific models are crucial for the advancement of our collective example.

Imaging Technology and Techniques: How Do They Work, Why Are They Used, and How Are They Relevant to Neurological Conditions?

Imaging techniques help researchers and clinicians to gain a better understanding of anatomy and physiology. Many different technologies exist that provide clinicians images into the many different components of the human body, and they serve different purposes for different patients. There are many, including MRIs, CT, PET and SPECT scans, x-rays, ultrasounds, and EEGs.
