An earlier study identified several modifiable risk factors for dementia. As the number of people living with dementia has grown, researchers decided an updated analysis was needed regarding the connection between these risk factors and dementia.

Researchers used data from a European sample of teens from the IMAGEN Consortium study, which measured resting-state fMRI activity at age 14, 16, and 18.

The study authors searched several databases to find correlations between tobacco smoking and COVID-19 during the pre-vaccination phase of the pandemic.

The researchers searched PubMed and Web of Science for studies published between 1990 and April 11, 2021, that investigated associations between possible risk factors and depression in people aged 60 and over.

Previous studies show anxiety and depression tied with increased punishment learning, while others show reduced reward sensitivity. The researchers of the current study wanted to obtain more specific information to inform how doctors treat mood and anxiety disorders.

As households worldwide sheltered in place during the start of the COVID-19 pandemic, children aged 12 experienced a range of sleep disturbances. Researchers of this study conducted a systematic review of these issues.

Depressive symptoms and sleep disorders, including insomnia, hypersomnia, and disrupted breathing, are considered heart disease risk factors. Other studies have linked sleep disorders and depression. This study analyzes heart disease risk in people with both sleep disorders and depression.

Investigators examined the incidence and severity of newly diagnosed anorexia nervosa and atypical anorexia nervosa in Canada before and during the COVID-19 pandemic.

Researchers analyzed genome-wide association studies that explored schizophrenia, heart failure, heart disease, blood pressure, and heart rate variability.

Previous studies have looked at the benefits of coffee and tea separately in dementia and stroke prevention. However, the researchers for this current study wanted to look at coffee and tea in combination.
