Using neuroimaging and fluid biomarkers from those with the familial form of frontotemporal dementia (FTD), researchers developed models of clinical and biomarker dynamics to determine the temporal sequences of biomarkers and clinical changes in f-FTD before disease progression begins.
COVID-19 infection has been linked to a range of lasting neurological and psychological disorders, including depression, memory problems, and Parkinson's-like disorders, within the first year following infection.
Dementia risk was 69% higher in older adults who slept for more than 8 hours per night, and 2 times higher for those who went to bed before 9 pm.
Middle-aged people who experience at least one nightmare a week are four times more likely to experience cognitive decline during the following decade. Older adults who experience weekly nightmares are twice as likely to develop dementia. The association is much stronger for men than women.
Rather than being simply a brain disease, researchers propose Alzheimer's disease could be a disorder of the immune system within the brain.
Getting the recommended amount of sleep, daily exercise, eating a healthy diet, and resisting alcohol and tobacco are among the seven identified lifestyle alterations those with diabetes should take to decrease their risk of developing dementia.
Good dental health can help protect against cognitive decline and dementia. Tooth decay was associated with a 23% increased risk of cognitive decline and a 21% increased risk of dementia.
Older adults who experience insomnia are at greater risk of developing memory deficits and long-term cognitive impairments.
Listening to music from their youth or songs with a strong emotional connection allows those with dementia to enhance social engagement and reduces neuropsychological symptoms of dementia such as anxiety, depression, and aggression. Musical intervention also sparks an emotional connection between the patient and their caregivers.
First responders at the World Trade Center who experience cognitive impairment and PTSD have a different presentation of white matter in the brain compared to first responders with cognitive impairment without PTSD. Researchers say the findings point to a new and specific form of dementia for those responders with PTSD.
Sedentary behaviors while sitting for extended periods of time, such as watching TV, are associated with an increased risk of dementia in older adults. However, older adults who spent time performing cognitively stimulating tasks, such as using a computer or reading, while sitting had lower dementia risks.
Older adults who spend their free time embarking on intellectually stimulating activities, such as reading, writing, or making crafts, have a 23% lower risk of developing dementia. Additionally, those who exercise and spend time socializing with family or friends also have a significantly decreased risk of dementia.
