Researchers report the retina may provide clues as to those at risk of developing Alzheimer's disease. A new study reports amyloid plaques have been discovered in peripheral areas of the retina in Alzheimer's patients. The amount of retinal plaques correlated with the amount of amyoid plaques in specific brain areas.
A new Johns Hopkins University study adds further evidence to the link between serotonin and dementia. According to researchers, lower serotonin levels may play a key role in memory decline and drive the progression 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.
A recent study in PNAS implicates alterations in the brain's glutamate signaling in people with PTSD. Neuroimaging revealed increased levels of mGluR5 in those with post traumatic stress disorder. Researchers report drugs that can reduce mGluR5 function could help reduce fear, stress and other symptoms of PTSD.
Brain inflammation is 30% higher in people with OCD than in their peers without the disorder, a new study reports.
The amount of amyloid plaques present within a person's brain can indicate the rate at which their cognition will decline in the following four years, a new study reports.
Study reports elevated amyloid plaque are not just a risk factor for Alzheimer's, but part of the disease and the earliest precursor before symptoms appear.
Researchers uncover how laughter releases endorphins in the brain.
Researchers report a cognitive test can help detect Alzheimer's in older people who express no symptoms of the disease.
Study reveals how the brain's opioid system modulates response to others in pain.
According to researchers, people who consider themselves to be recreational cocaine users may be closer to addiction than they think.
Problems with olfaction associated with Alzheimer's could be a result of damage to neurotransmitter and neuromodulator neurons in the forebrain, a new study reports.
