Secondary infections and novel inflammatory events, even ones that occur external to the brain, amplify the brain's immune response and detrimentally impact cognition in mouse models of Alzheimer's disease.
Obesity has been linked to severely restricted blood flow in the brain. Reduced blood flow in the brain, or cerebral hypoperfusion, can be an early indicator of vascular dementia and Alzheimer's disease.
Older adults with higher fear of memory loss and dementia report a significant decrease in their quality of life and reported more failures in memory.
Older adults can be more focused, less mentally restless, and not as impeded by anxiety than those in younger generations.
Artificially inducing peripheral inflammation in mice triggered the sudden onset of delirium-like cognitive dysfunction, and this was mediated by a disturbance in energy metabolism.
8% of patients with a history of seizures reported experiencing hallucinations. Of the 8%, 53% reported one or more suicide attempts. Findings suggest hallucinations associated with seizures are not just incidental but are a marker for mental health risks and suicidal behavior.
Researchers argue the existing categorical framework for mental illnesses needs to be revised, citing a substantial overlap between disorders, with most patients meeting the criteria for multiple disorders.
Hepatitis C virus increases the expression of SOCS, dulling the normal immune system response to viral infections. This may explain why Hepatitis C 'hides' in the immune system, leading to a lack of diagnosis in those suffering the infection.
