When an adult starts to display cognitive issues, it’s easy to jump to conclusions and think, “It must be dementia!” And yes, sometimes the person is developing a type of dementia. However, that’s not always the case. In fact, memory loss can actually result from one of the most basic bodily functions – sleep (or the lack thereof).
It turns out that a new study suggests that sleep can have a major effect on the brain’s ability to function. This study involved 2,822 men who, on average, were 76 years of age. The researchers followed these participants for about three years in order to gauge their sleep and brain function.
Researchers used an actigraph device that was placed on each participant’s wrist in order to record wrist and body movements that were then used to identify sleep issues. In this particular study, the devices measured a variety of indicators, including total sleep time and sleep efficiency. This data was collected over five ni...
A new study has concluded that a type of age-related memory loss not related to Alzheimer’s disease could be reversible. A team of Columbia University Medical Center (CUMC) researchers, led by Nobel laureate Eric R. Kandel, MD, has concluded that deficiency in the hippocampus of the protein RbAp48 is likely a significant contributor to age-related memory loss. The great news is that this form of memory loss can be reversed.
For the study, Kandel’s team used postmortem human brain cells as well as mice. The conclusion of the study offers the strongest causal evidence to date that age-related memory loss and Alzheimer's disease are distinct conditions. The findings were published in the August 29, 2013 online edition of Science Translational Medicine .
The study focus was to look for direct evidence that age-related memory loss is a separate disease from Alzheimer’s disease. The researchers performed gene expression analyses of postmortem brain cells from ...
This is the first randomized controlled trial comparing two different treatment approaches for patellar (kneecap) dislocation. Forty patients with dislocation of the kneecap were included. All patients had a traumatic injury either from a military exercise or a sports activity. All of the patients were in the military. Most were men between the ages of 19 and 22. The real question behind this study was: should a primary (first-time) patellar dislocation be treated right away with surgery? Or can it be managed nonoperatively with a knee orthosis (brace). What are the long-term results of both approaches? There are many surgical ways to stabilize a dislocated patella. In this study, two types of procedures were used based on the type of damage present. Besides a dislocated patella, patients also had an injury to the patellofemoral ligament requiring repair or reconstruction. The mechanism of dislocation was a sudden displacement of the patella laterally (away from the other knee). The sof...
