Brain Blogger covers topics from multidimensional biopsychosocial perspectives. It reviews the latest news and stories related to neuroscience, psychiatry, and neurology. It serves as a focal point for attracting new minds beyond the science of the mind-and-brain and into the biopsychosocial model.
Alcohol (when used commonly refers to ethanol) is consumed widely around the world for numerous reasons. Its properties have been both praised and demonized. In humans it generally acts as a depressant with, conversely, mild stimulating effects of some parts of the brain. At low levels of consumption alcohol has minimal effects on a person; [...]...

Depression is a subtle thing. It can easily take on the disguise of other illnesses or temporary conditions.
Tired? Who isn’t? Sad? Well, the world can be depressing. Worried? Yeah, that’s why we all have grey hairs. Can’t sleep well? Join the club. Aren’t hungry? You’re just too busy. Unfocused? You just need to simplify. Irritable? [...]... Read more »
Inflammation is a hot topic in medical research, with studies showing links to heart disease, dementia and longevity. Depression is a relatively new addition to the list of inflammation-associated diseases, with two recent publications demonstrating altered levels of inflammatory molecules in the blood of patients with major depressive disorder (MDD). Both studies evaluated the levels ... Read more »

George Huntington was the son and grandson of medical practitioners. He gave rise to a great interest in the origins of this disease which now bears his name.
At the age of 22, the year following his graduation from medical school at Columbia, George Huntington (1850-1916) made his contribution to medical research, publishing his report on [...]... Read more »

Right now, I have hundreds of songs on my mp3 player. I listen to everything from heavy metal when I run, to classical when I need to relax, to jazz when I am cooking. I listen to Broadway show tunes, movie soundtracks, and classic rock, depending on my mood. I also have tracks of nursery [...]... Read more »

In recent years, there has been renewed interest in creating new smallpox vaccines due to the threat of the smallpox pathogen being used as a bioterrorism tool. The vaccinia virus vaccine has been used to prevent smallpox disease since the late 18th century and, until 30 years ago, most countries conducted routine smallpox vaccination programs. [...]...

Many people, at one time or another, have witnessed this ritual: a beaming new mother enters with baby pictures. A group of genuinely excited women gather around the new mother admiring the pictures as they are passed around.

These days, sleep is often seen as an expendable resource. With so much work to do and limited time to accomplish tasks, going to sleep later and waking up earlier seems so natural. For some people, lack of sleep was used to prove toughness and stamina. It was common for physician trainees to boast (in [...]... Read more »

When most people think of torture, the first thing that comes to mind is unimaginable, unendurable pain. Physical pain is, however, the one thing that tends to remain in the torture chamber, the hidden cells of illegal prisons after the victim has left. As terrible as the physical after effects of torture may be, the [...]... Read more »

America is arguably one of the most diverse nations in the world. While such diversity can provide opportunities for unique social and cultural interactions, it can also present opportunities for poor medical care.

Millions of older adults suffer from significant memory loss, despite the lack of a diagnosis of dementia-causing disease. This memory loss can lead to a significant decline in quality of life and often remains undiagnosed and untreated. Recently, however, scientists have begun to study the role of glucose regulation in cognitive enhancement of adults. Cognitive ... Read more »

Sometimes we forget that doctors are just like everyday people. They have families, they are members of parent/teacher organizations (PTOs), they help their children with school projects and homework, and they, in many cases, are still repaying school loans. You name it, and yes, the doctor has probably experienced it. So too is the case [...]... Read more »

In addition to the popular saying, “An apple a day keeps the doctor away”, maybe some day we can say the phrase, “Vitamin C a day keeps cancer away”.

A recent issue of the journal Neurology published two separate case-controlled studies that showed a decreased risk for Parkinson’s disease associated with both cholesterol-lowering medication and blood pressure-lowering medication.
A common class of cholesterol-lowering medications, HMG-CoA reductase inhibitors (also collectively called “statins”), includes the well-known and often-prescribed atorvastatin (Lipitor), simvastatin (Zocor), lovastatin (Altocor, Mevacor), and pravastatin [........... Read more »

Researchers are constantly trying to find new drugs or forms of therapy that can be used to treat cancer. Quite often when a possible treatment is discovered, being allowed to test a drug or other experimental cancer treatment at a clinical level is difficult. For example, after an anti-carcinogenic drug has been thoroughly tested at ... Read more »

Many people have a general familiarity to the obvious symptoms of stroke complications: paralysis, thinking and concentration deficits, speech problems, emotional difficulties, and daily living problems. However, many are unaware of the possible pain complications.

Despite the fact that functional MRI was discovered in the early 90’s, scientific research related to its clinical applications is still at an early stage. The first paper on the use of functional MRI (fMRI) in Alzheimer’s disease came out as late as 1999. Today, fMRI is being intensively studied in a number of other ... Read more »

According to a twenty-year longitudinal study of over 4000 individuals, happiness is indeed contagious.

The clinical diagnosis of Alzheimer’s disease (AD) at the earliest clinical stages can be difficult. Given the variability in clinical threshold at which there is functional compromise in one’s social and professional life — a necessary component to AD diagnosis — there are several in-organic factors that affect early detection.
