The word dementia describes a set of symptoms that may include memory loss and difficulties with thinking, problem-solving or language. Dementia is caused when diseases, such as Alzheimer’s disease or a series of strokes, damage the brain. Dementia is progressive, which means the symptoms will gradually get worse. In most cases, there is no way to cure the diseases that cause dementia. However, there are drugs and treatments available that may help alleviate some of the symptoms.
Alzheimer's and Dementia
- Alzheimer's: Synthetic protein blocks toxic beta-amyloid April 16, 2019
Scientists have designed a protein that folds into alpha sheets that can block toxic beta-amyloid in brain cells before it forms into large clumps.
- Syncing brain waves may fight age-related memory problems April 8, 2019
Working memory tends to decline with age, and this problem is characterized by poor synchronicity between brain regions. Can researchers 'fix' this issue?
- Dementia: Amyloid PET scans can improve diagnosis and care April 3, 2019
Using brain scans that can detect hallmarks of Alzheimer's could improve diagnosis and clinical care of people with dementia and mild cognitive impairment.
- This drug failed to treat cancer, but it could improve dementia March 29, 2019
Scientists have found that an experimental drug that failed against cancer may treat dementia instead. However, can they test it in clinical trials?
- Smoking may not be related to dementia risk after all March 28, 2019
Study of 531 cognitively healthy older adults over 11.5 years finds no link between smoking and dementia after accounting for 'competing risk' of death.
- Is this a better way to deliver drugs to the brain? March 28, 2019
According to a new study in mice, shorter-wave ultrasound pulses could help scientists deliver drugs straight into the brain more safely and efficiently.
- The key to brain health: Light but frequent exercise March 25, 2019
New research shows that light and moderate exercise benefits the brain both immediately and in the long run, providing a person is active frequently.
- Study links severe gum disease to raised dementia risk March 20, 2019
Another study has linked chronic periodontitis to higher dementia risk. However, it is the first to show that the link is independent of lifestyle factors.
- Light and sound therapy may boost brain function March 19, 2019
New evidence suggests that a combined light and sound stimulation therapy could boost brain health and improve the symptoms of Alzheimer's disease.
- Alzheimer's disease: An eye test could provide early warning March 18, 2019
One day, a quick eye test may be able to pick up important information about brain health. Specifically, it may be able to identify signs of dementia.
