Socioeconomic Factors Influence Cognitive Health and Dementia Risk

A new study reveals that socioeconomic factors like education, occupation, and wealth play a role in the risk of cognitive impairment and dementia in later life. Tracking over 8,000 adults in England, researchers found that people with higher socioeconomic status were less likely to transition from healthy cognition to impairment and more likely to recover from mild impairment.

Brain Blood Flow Issues Linked to Mild Cognitive Impairment

Older adults with mild cognitive impairment (MCI) face higher cerebrovascular impedance, or resistance in brain blood flow, according to a new study. Researchers found this increased resistance leads to hypoperfusion, or reduced blood flow in the brain, which may contribute to cognitive difficulties in aging adults.

Psychosis Cognitive Impairment Linked to Brain Network

New research reveals that cognitive impairments in psychotic disorders, like schizophrenia and bipolar disorder, are connected to brain network organization. This connection is evident even before the first psychotic break in at-risk individuals, offering potential for early diagnosis and intervention. The study highlights a novel brain network-cognition relationship that could lead to targeted treatments for these often treatment-resistant symptoms.

Peptide Improves Cognition in Schizophrenia

Researchers developed a novel peptide, KS-133, to target cognitive dysfunction in schizophrenia. By using a brain-targeting peptide, KS-487, they successfully transported KS-133 across the blood-brain barrier. Their nanoparticle-based drug delivery system improved cognitive functions in mice, offering a new therapeutic strategy.

COVID-19 Vaccines May Reduce Virus-Induced Memory Problems

COVID-19-induced cognitive impairment is linked to the protein IL-1β. Researchers found that vaccination can reduce brain inflammation and memory loss in rodent models. This suggests vaccines may lower the risk of long COVID brain fog. More research is needed to confirm these findings in humans.

Trouble Falling Asleep at Bedtime or in the Middle of the Night? It Could Impact Your Risk for Developing Dementia

A new study reveals people who have trouble falling asleep within 30 minutes and those who use sleep medications are at increased risk of developing dementia as they age. However, those who have trouble falling back asleep after they woke up during the night were less likely to develop dementia.

Impaired Kidney Function Linked to Cognitive Disorders

Of patients with dementia, 7% had chronic kidney disease while 9% had albuminuria, a urinary marker for kidney disease. Chronic kidney disease was associated with a 51% increased risk of developing dementia.
