In one study (n=131) researchers looked at the relationship between depression and cognition in people with Alzheimer’s Disease. The researchers found that in their study there was no significant change in cognition in cases with remission of Depression at 24 weeks.

The relationship between Depressive symptoms in women over the age of 85 was examined in this study (n=302). Researchers used the 15 item Geriatric Depression Scale and found that with a score of <6 at baseline 46% had normal cognitive status 5 years later. With a score >6 at baseline 19% had normal cognitive status 5 years later.

In a small fMRI study researchers looked at 15 people with late life depression and 13 controls . Previous research would suggest decreased executive performance in people with Depression. In this study the researchers found that on a test of executive performance there was increased activation in various parts of the Brain in people with late life Depression compared with controls. The study showed activation was increased in areas including the Superior Frontal cortex bilaterally, Insular cortex, Caudate and Putamen.

In one study researchers looked at 581 people undergoing major non-cardiac surgery. They identified a number of risk factors for developing Delirium and stratified people into low and high risk groups. For the entire group the risk of  postoperative delirum was 40% at 1-2 days post-op. The high risk group developed Delirium in 72% of cases if they had postoperative pain and used high dose Opioids. In comparison those in the low risk group who used low-dose Opioids and low level pain developed Delirium in 20% of cases. As Delirium is common, these findings are helpful in monitoring emerging Delirium.

There is a write-up here of a study looking at bright light therapy for daytime sleepiness in 18 people with traumatic brain injury.
