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.

- Diabetes and Alzheimer's: What's the link? February 17, 2019
Although scientists have linked Alzheimer's and diabetes, the exact connection has been difficult to unpick. A recent study now gives further insight.
- Study finds new cognitive decline mechanism in Alzheimer's February 15, 2019
A new animal study has identified the cellular mechanism that leads to reduced blood flow to the brain, which, in turn, impacts cognitive function.
- Inflammation in midlife hastens cognitive decline February 15, 2019
Understanding the risk factors of cognitive decline are now more important than ever. A recent study examined the potential role of inflammation.
- Alzheimer's: How do tau tangles grow? February 12, 2019
Researchers use a mathematical model and lab experiments to unravel the process through which tangles of the protein tau grow in length.
- Blood-clotting protein contributes to Alzheimer's February 7, 2019
Though experts typically name beta-amyloid plaques as the main culprits in Alzheimer's disease, new research finds another factor: a leaked blood protein.
- Does education really protect against dementia? February 7, 2019
Does the length of time an individual spends in education reduce the risk of developing dementia? A new, large-scale study investigates.
- Dementia: Could gut bacteria play a role? February 1, 2019
A new study links changes in gut bacteria to dementia. The researchers hope that their findings might, one day, help develop more effective treatment.
- Dementia: The worrying 'rise of pseudomedicine' January 31, 2019
In a recent article, a team of neurologists attacks an ongoing increase in pseudomedicine that claims to protect brain health and treat dementia.
- Hearing loss and cognitive decline: Study probes link January 30, 2019
Data from an 8-year study of 10,000 men aged 62 or older reveals a link between hearing loss and a markedly greater risk of subjective cognitive decline.
- Mild cognitive impairment: Reducing blood pressure can lower risk January 28, 2019
Controlling systolic blood pressure to below 120 mm Hg significantly lowered the risk of mild cognitive impairment in older adults.
