Researchers have discovered a link between elevated levels of amyloid beta and worsening anxiety symptoms. The research supports the hypothesis that some psychiatric symptoms could indicate the early stages of Alzheimer's disease.
22% of study participants with severe gum disease developed dementia, and 23% diagnosed with mild cognitive impairment suffered extreme tooth loss. Only 14% of those with healthy gums were later diagnosed with the neurodegenerative disorder. The findings add further evidence for the link between dental hygiene and dementia.
Researchers have coupled machine learning with neuroimaging to detect early forms of dementia.
McGill University researchers have developed a deep learning algorithm capable of detecting signatures of dementia in patients two years before the onset of symptoms by reviewing a single PET brain scan.
Older adults who experience problems completing simple financial tasks, such as calculating their change, may be at increased risk of Alzheimer's disease. Problems with financial management have often been associated with later stage dementia. A new study reveals this could be one of the earliest signs of dementia and may be correlated with a build-up of amyloid plaque deposits.
Alzheimer's risk is increased for those with anosognosia, a condition in which sufferers are unaware they are experiencing memory loss.
A new study reports bilingual people have an advantage when it comes to brain plasticity. Researchers report being multilingual could help stave off cognitive decline associated with dementia.
A new study reports lower concentrations of α-synuclein in the cerebrospinal fluid of Parkinson's patients is associated with reduced cognitive performance.
Scientists have taken a step toward developing a blood test for Alzheimer's, finding a group of markers that hold up in statistical analyses in three independent groups of patients.
According to researchers, brain training apps can help improve mood and memory in people with mild cognitive impairment, but the training loses its effectiveness once dementia has been diagnosed.
Middle-aged and older people who stay mentally active have a lower risk of developing mild cognitive impairment.
A new study reports higher levels of Omega 3 can boost the neuroprotective effects of B vitamins.
