Financial Scam Vulnerability: Brain Risk Factors

by William Yates, M.D. in Brain Posts

It is always frustrating when you hear about a financial scam that has target a vulnerable population like the elderly population.Elderly individuals may be targeted for a variety of reasons. First, they often have financial resources. Second, they may be a generally more trustworthy group increasing risk for falling for a scam. Third, elderly may suffer from some age-related brain changes that impair cognition and judgment.A recent research study suggests specific brain deficits may increase vu........ Read more »

Theory of Mind in Brain Development

by William Yates, M.D. in Brain Posts

Theory of Mind (ToM) is a concept describing the ability to understand what another person is thinking or feeling.Today in my neuroscience medicine news review I ran across a novel, interesting and important research study targeting brain development in ToM.Normally developing children develop ToM around 4 years of age. In the study published in Nature Communications, a research team at the Max Planck Institute in Germany studied white matter development in 3 to 4 year old children.Using a serie........ Read more »

Earliest Brain Changes in Alzheimer's Disease

by William Yates, M.D. in Brain Posts

Amyloid brain plaques are well-known pathological changes associated with Alzheimer's disease. Changes preceding amyloid plaque build up are less well studied and understood. Some of this relates to limitations to current imaging technology.Klementieva and colleagues from Sweden and Spain recently published an important reserach topic in this area.Their studied used a rat model of Alzheimer's disease and imaging techniques that included infrared microspectroscopy and gel electrophoresis.The........

Improving Hearing-Aid Access in Older Adults

by William Yates, M.D. in Brain Posts

There are significant barriers to widespread use of hearing-aids in older adults with age-related hearing loss.Sensitivity to the stigma of wearing a hearing-aid is one barrier.Cost is another significant barrier. In the U.S., bilateral hearing-aid purchase amounts to a cost of $2400 to $5800. This cost is typically not covered by Medicare or other health insurance plans.I ran into a interesting manuscript on looking at an alternative less costlier approach to hearing-aid selection and purchase.........

Bad news for DARPA's RAM program: Electrical Stimulation of Entorhinal Region Impairs Memory

by The Neurocritic in The Neurocritic





The neural machinery that forms new memories is fragile and vulnerable to insults arising from brain injuries, cerebral anoxia, and neurodegenerative diseases such as Alzheimer's. Unlike language, which shows a great deal of plasticity after strokes and other injuries, episodic memory – memory for autobiographical events and contextual details of past experiences – doesn't recover after

Your Brain On God: Reward and Motivation

by William Yates, M.D. in Brain Posts

William James authored a seminal book titled The Varieties of Religious Experience: A Study in Human Nature that was published in 1902.In this work, James reviewed the nature of religious experiences and noted a lack of scientific inquiry into this human phenomenon.James would have been extremely interested in a recent scientific inquiry into the religious experience from brain researchers at the University of Utah and Harvard University.In this study, functional magnetic resonance imaging (fMRI........

Airplane Headache II: The Sequel

by The Neurocritic in The Neurocritic




Airline travel during the holidays is one big headache. But for some people, “airplane headache” is a truly painful experience. The headache occurs during take-off and landing, is unique to plane travel, and is not associated with other conditions. The pain is severe, with a jabbing or stabbing quality, and located on one side of the head (usually around the eye sockets or forehead).

Benefits of Physical Activity in Parkison's Disease

by William Yates, M.D. in Brain Posts

Parkinson's disease (PD) is a progressive neurodegerative disorder estimated to affect 7 to 10 million individual worldwide.The primary mechanism for Parkinson's disease is a reduction in the neurotransmitter dopamine in the midbrain region of the substantia nigra highlighted in red in the figure.PD impairs motor and cognitive functions and leads to significant decline in psychosocial functioning.Drugs for PD can be effective in reversing and slowing the progression of the illness. However, resp........ Read more »
