Big data finds changes in blood flow mark the earliest sign of Alzheimer's. Additionally, the study found cognitive changes begin earlier in the disease progression than thought.
PET imaging study reveals higher levels of mGluR5 in those with PTSD who had suicidal thoughts. The findings could serve as a biomarker to assess suicide risk in people with PTSD.
A new blood test for Alzheimer's disease is up-to 94% accurate at predicting dementia before symptoms appear. The test's accuracy is increased when genetic predisposition and age are taken into account. The new test may eventually replace PET neuroimaging, currently considered the gold standard, for early detection of Alzheimer's.
Researchers have devised a new blood test that can detect if amyloid had begun to accumulate in the brain. The test help physicians diagnose Alzheimer's disease in a cheaper, less invasive way than currently available. The researchers will present their findings at the Alzheimer's Association International Conference in London.
According to researchers, circadian disruptions can occur years before symptoms of Alzheimer's develop. The findings could help to identify those at risk of developing the neurodegenerative disease as they age.
Researchers have identified a brain circuit responsible for vocal tics in nonhuman primates.
Neuroimaging technology has limited applicability when assessing a defendant's sanity, a new study reports.
A new study links hippocampal inflammation in multiple sclerosis with an increased risk of developing depression.
