  • A small pilot study has confirmed that inflammation in the blood plays a role in chemobrain.

A pilot study involving 22 breast cancer patients currently receiving chemotherapy (mean age 54), has found that those with higher levels of inflammatory biomarkers did significantly worse on tests for short-term visual memory.

  • Difficulties in remembering past events and imagining future ones are often experienced by those with multiple sclerosis.
  • A trial involving patients with MS has found that training in mentally visualizing imaginery scenarios can improve their ability to recall past events.
  • Deficits in event memory and imagination have also been found in older adults, so this finding might have wider application.

Training in a mental imagery technique has been found to help multiple sclerosis patients in two memory domains often affected by the disease: autobiographical memory and episodic future thinking.

  • A small study found mindfulness training had an observable effect on the brains of PTSD sufferers.

A pilot study involving 23 military veterans with PTSD found that those who received mindfulness training showed reduced PTSD symptoms, and brain changes that suggest a greater ability to shift and control attention.

When we tell people about things that have happened to us, we shape the stories to our audience and our purpose. The amount of detail we give and the slant we give to it depends on our perceptions of our audience and what we think they want to hear. Does this change our memory for the event?

Analysis of post-mortem with and without dementia has found lipopolysaccharide, a component of an oral bacterium (Porphyromonas gingivalis), in four out of 10 Alzheimer’s disease brain samples, but not in any of the 10 brains of people who didn’t have Alzheimer’s.

  • Focusing on concrete details when experiencing a traumatic event may, oddly enough, protect you more from the power of those memories, than if you tried to distance yourself from what you are experiencing.

Can you help protect yourself from the memory of traumatic events? A new study suggests that, by concentrating on concrete details as you live through the event, you can reduce the number of intrusive memories later experienced.

  • The American Academy of Pediatrics (AAP) has updated its concussion recommendations.

The American Academy of Pediatric now supports children and teens engaging in light physical activity and returning to school as they recover. It also now advises against complete removal of electronic devices, such as television, computers and smartphones, following a concussion.

  • Some athletes who experience sports-related concussions have reduced blood flow in parts of their brains even after clinical recovery.

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.

  • A preliminary study suggests adults with persistent difficulties after TBI may benefit from a metacognitive training program in conjunction with use of Ritalin.

A small study involving 71 adults who struggled with persistent cognitive difficulties after suffering a traumatic brain injury at least four months before has compared two cognitive training programs with and without drug therapy.

The two six-week programs were

  • Type 2 diabetes is known to increase the risk of Alzheimer's disease.
  • In a reasonably large study, diabetes was found to be linked with higher levels of tau protein, regardless of the presence of dementia.
  • Diabetes was also linked with greater brain shrinkage.
  • The finding adds to evidence that diabetes increases the risk of cognitive impairment in old age.

A study involving older adults has found that diabetes was associated with higher levels of tau protein and greater brain atrophy.
