Sex, Violence and The Male Warrior Hypothesis

by Shaheen Lakhan in Brain Blogger

Throughout the history of human civilization, wars have a common feature of being practiced primarily by males. This group aggression by males is a persistent trait of human behavior, seen across different continents among civilizations that have developed independent of each other.
Also, experimental evidence suggests that compared to females, male behavior and psychology is more [...]... Read more »

Is Time on Your Side?

by Shaheen Lakhan in Brain Blogger

Physicians are under mounting pressure to increase efficiency in the provision of medical care. That is, see more patients in less time for less money. But, since speed and accuracy do not always go hand-in-hand, does this increased physician efficiency lead to quality medical care? A recent study published in the Archives of Internal Medicine [...]... Read more »

Weight in the Workplace

by Shaheen Lakhan in Brain Blogger

The statistics are everywhere: most of the adults in the United States are overweight or obese. These conditions are, of course, responsible for increased health care costs owing to chronic diseases such as diabetes, high blood pressure, high cholesterol, and heart disease. The patient may pick up some of these excess expenses, but society incurs [...]... Read more »

White Bears – The Paradox of Mental Suppression

by Shaheen Lakhan in Brain Blogger

Whatever you do, don’t think of a white bear. Go on, close your eyes, relax, but don’t think of a white bear… So, what happened? Most likely, you were overwhelmed by thoughts of a white bear. This mini-experiment highlights the fascinating paradox of thought suppression. That is, once we explicitly try not to think of [...]... Read more »

Is Your Doctor Happy or Burnt-Out?

by Shaheen Lakhan in Brain Blogger

Is your doctor happy? This is something that may have never crossed your mind: the idea that your personal physician may not be pleased with the current state of his or her life. Even if it has, perhaps you were of the opinion that it was not of minor importance if it did not affect [...]... Read more »

One Size Does Not Fit All

by Shaheen Lakhan in Brain Blogger

Up to half of drug therapy is ineffective, according to recent statistics. This leaves patients’ diseases untreated, but also places them at risk for side effects and drug interactions. The reason for the unpredictability in the effectiveness of medication comes from a variety of factors: individual differences in enzymes that metabolize drugs, variations in drug [...]...

The Secret to Good Health – Listen to the Data

by Shaheen Lakhan in Brain Blogger

A recent study proved what we all already know… that healthy living really does improve long-term health. A lot. The US-based study found that not smoking, maintaining a healthy weight (BMI <30), exercising regularly (3.5 hours/week) and eating a balanced diet (high in fruits, vegetables, and whole grains, low in meat) reduced the risk of [...]...

Sugar and Spice and Everything Nice?

by Shaheen Lakhan in Brain Blogger

A New Look at Medical Errors in Residency Training

by Shaheen Lakhan in Brain Blogger

It’s a phenomenon that medical educators have long suspected but haven’t been able to prove: a rise in medical errors when newly-hatched physicians begin their residency training programs in July. This suspected occurrence has been studied several times, but until recently, no conclusive evidence existed that it actually was true. For the first time, a [...]... Read more »

The Evolution of Depression

by Shaheen Lakhan in Brain Blogger

Millions of people around the world suffer from depression, the most common mental disorder of all. Since depression appears to be largely genetic, several long-standing questions continue to bedevil researchers. Have the genes for clinical unipolar depression undergone selective evolution–or is depression a random product of mutation, evolutionary drift, or other non-selective forces?
The symptoms of [...]... Read more »

A Small Sip from the Fountain of Youth

by Shaheen Lakhan in Brain Blogger

The search for eternal youth is as old as time itself. The theme of immortality winds its way through religion, mythology, poetry, fiction, and modern movies. Usually, stories of those who have achieved immortality expose the curse of eternal life, rather than the blessing of perpetual youth. While living forever may never be possible, life [...]...

Is Knowledge Power? Direct-to-Consumer Genetic Testing

by Shaheen Lakhan in Brain Blogger

The completion of the sequencing of the human genome in 2003 was an outstanding scientific accomplishment. This achievement, together with advances in technology and the forces of capitalism and competition, has brought genetic testing directly to the consumer. However, this Pandora’s box is proving difficult to manage for many people.

Are Physicians Spending Too Much Time Diagnosing Patients?

by Shaheen Lakhan in Brain Blogger

Dizziness is responsible for nearly 3 million emergency room visits every year in the United States. In most of the cases, the dizziness is caused by a benign inner ear problem, or is the result of short-lived discomfort or distress, including anxiety, depression, or certain phobias. However, approximately 4% of patients that present to the [...]... Read more »

Possible Medical Application of a Smart Drug

by Shaheen Lakhan in Brain Blogger

Cognitive enhancers, also known as nootropics, are a category of drugs with the ability to increase mental performance. Many rave about such “smart drugs” helping them to study, take tests, or increase work performance. Ginkgo biloba, piracetam, and vinpocetine are some popular cognitive enhancers, all with varying mechanisms of action in the human brain. For [...]... Read more »

Two Wrongs Make a Right – Abnormal Brain Circuitry May Stop Abnormal Movement

by Shaheen Lakhan in Brain Blogger

A solution to an abnormal neurological movement problem can perhaps be abnormal as well. The irregular wiring of the brain may actually eliminate dystonia — repetitive movements and atypical postures. According to the Journal of Neuroscience, changes in brain pathways may actually counteract the genetic mutations for the movement disorder. This idea can explain why [...]... Read more »

How Culture Shapes Our Mind and Brain

by Shaheen Lakhan in Brain Blogger

Most people would agree that culture can have a large effect on our daily lives — influencing what we may wear, say, or find humorous. But many people may be surprised to learn that culture may even effect how our brain responds to different stimuli. Indeed, until recently, most psychology and neuroscience researchers took for [...]... Read more »
