Traumatic Brain Injury Symptoms Could Be Mistaken for PTSD

A few studies in recent years are showing possible signs that soldiers who have had a traumatic brain injury (TBI) caused by battlefield explosions are mistakenly diagnosed with post traumatic stress disorder (PTSD). In fact, what might be happening is that the soldiers’ pituitary glands have been damaged by the blast–which has led them to…

A Criticism Of Brain Training – And An Answer To It

An interesting paper came across my radar week – “Placebo effects in cognitive training” published in PNAS (with a paywall, unfortunately).

Is Pregnancy Brain a Real Thing?

You’ve likely heard the term “pregnancy brain” used by self-deprecating mothers-to-be when they aren’t feeling or behaving up to their usual cognitive snuff. Some pregnant women say they often forget things easily, are less attentive than normal, and just don’t seem like themselves. But does so-called pregnancy brain manifest itself in measurable cognitive loss? Myra…

Why Can’t Our Brains Figure Out Magic Tricks?

As intellectually mature adults, we know that when we see a magic trick successfully pulled off, it’s not really magic that gets us, but some sort of trick that makes us think we’re seeing something that didn’t––and couldn’t––really happen. Knowing this, though, doesn’t make a magic trick any less entertaining or amazing. So why can’t…

FTC Takes Action on Brain Training

Unfortunately, too many programs have little or no science backing up their claims to improve brain function. BrainHQ is different: people with deep knowledge of the brain designed our exercises, and a wealth of…
