Cognitive decline may be detected using network analysis, according to Concordia researchers

-
Researchers use network analysis to study whether it can reveal the subtle changes associated with subjective cognitive decline that cannot otherwise be detected through standard test analyses. By running a statistical analysis of data merged from two large Canadian data sets, the researchers were able to visualize the strength of relationships between the nodes among people who are classified as cognitively normal (CN), or who have diagnoses of subjective cognitive decline (SCD), mild cognitive impairment (MCI) or Alzheimer's disease (AD).

Reducing 'vivid imagery' that fuels addiction cravings

New research shows promise in treating addiction cravings by combining eye movements and guided instructions to process memories. Researchers transformed dysfunctional memories stored in the brain through processing and integration. EMDR was as effective as cognitive behavioral therapy for cravings with the combination of both resulting in more reduction in craving than cognitive behavioral therapy (CBT) alone. Both groups (experimental group and control group using only CBT) had clinically significant reductions in cravings, repetitive negative thoughts, and irrational cognitions, with the experimental group showing greater decreases overall.   http://dlvr.it/SyzZrK

A study using a tiny roundworm could pave the way for new treatments for neurodegenerative disorders. Researchers linked the worm gene swip-10 to copper regulation -- a vital element for brain health found in everyday items like wiring and cookware. Understanding the roles of swip-10 and MBLAC1, a protein involved in processing cellular materials, could lead to the development of effective medications for neurodegenerative diseases. This research opens new avenues for advancing brain disease treatments. http://dlvr.it/TDZpjl
