A study involving 66 healthy young adults (average age 24) has revealed that different individuals have distinct brain connectivity patterns that are associated with different ways of experiencing and remembering the past. |
Sleep, as I have said on many occasions, helps your brain consolidate new memories. I have reported before on a number of studies showing how sleep helps the learning of various types of new information. |
The question of the brain's capacity usually brings up remarks that the human brain contains about 100 billion neurons. If each one has, say, 1,000 or more connections to other neurons, this produces some 100 trillion connections in which our memory can be held. |
Growing research has implicated infections as a factor in age-related cognitive decline, but these have been cross-sectional (comparing different individuals, who will have a number of other, possibly confounding, attributes). |
A sleep study involving 28 participants had them follow a controlled sleep/wake schedule for three weeks before staying in a sleep laboratory for 4.5 days, during which time they experienced a cycle of sleep deprivation and recovery in the absence of seasonal cues such as natural light, time inf |
I've spoken before about how the presence or absence of the “Alzheimer's gene” may affect which lifestyle changes are beneficial for you. |
A study involving 14 years of health records from more than 274,000 Northern Californians has assessed the relative dementia risk of six different ethnicities. The average annual rate of dementia was: |
After Alzheimer's disease, the next most common type of dementia is Lewy Body disease. Far less widely known, this form of dementia is often diagnosed quite late. |
A natural experiment involving 5,740 participants in a MOOC ( massive open online course) has found that when students were asked to assess each other's work, and the examples were exceptional, a large proportion of students dropped the course. |
A systematic literature review of computerized training for attention and executive function in adults who suffered a brain injury (TBI or stroke) has concluded that there is encouraging evidence that such programs can help. |
In the study, mice were repeatedly given extremely mild concussive impacts while anesthetized. The brain's response to a single concussion was compared with an injury received daily for 30 days and one received weekly over 30 weeks. |
We know that traumatic brain injury increases the risk of later developing neurodegenerative disorders such as Alzheimer's disease, but we haven't known why. New mouse studies suggest a reason. |
Adding to evidence that the standard assessments are inadequate to determine whether concussed athletes are fit to return to action, an advanced MRI technique that detects blood flow in the brain shows that hat brain abnormalities persist beyond the point of clinical recovery after injury. |
An online national survey of 2,012 adult Americans (of whom 948 were parents) has found that, while the vast majority (87%) don’t know the definition of a concussion and many don’t know the injury is treatable, there is a high level of concern and even fear across the country. |
Another study adds to the growing evidence that a Mediterranean diet is good for the aging brain. |
A two-year study which involved metabolic testing of 50 people, suggests that Alzheimer's disease consists of three distinct subtypes, each one of which may need to be treated differently. The finding may help explain why it has been so hard to find effective treatments for the disease. |
Mindfulness meditation is associated with various positive benefits, one of which is improved attention, but it might not be all good. A new study suggests that it may have negative cognitive consequences. |
