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.

- How frontotemporal dementia affects 'moral emotions' June 17, 2019
Scientists find a key difference between Alzheimer's and frontotemporal dementia: the latter affects a person's 'moral emotions' while the former does not.
- How is education linked to Alzheimer's progress? June 12, 2019
New research asks to what extent, if any, a person's level of education is linked to the presence of Alzheimer's disease and the rate of cognitive decline.
- How ultrasound could help curb Parkinson's June 10, 2019
Mouse study shows that focused ultrasound and injected microbubbles can help curb early Parkinson's disease by allowing drugs to access the brain.
- Parkinson's: New gene therapy shows promise for prevention June 7, 2019
Researchers from Japan have tested a new gene therapy against Parkinson's disease using mouse models. Their results suggest that the approach is effective.
- Can blood pressure drugs help reduce dementia risk? June 5, 2019
