Blood Tests Does Identify Postpartum Depression Using Hormone Levels
Summary: Women who develop postpartum depression (PPD) may have distinct neuroactive steroid levels during the third trimester of pregnancy. A study found that those with PPD had lower levels of pregnanolone, which reduces stress, and higher levels of isoallopregnanolone, which increases stress. This hormonal imbalance may disrupt the brain’s ability

Oral Bacteria and Stroke Risk Are Related to Oral Bacteria
Summary: A new study finds that the bacteria Streptococcus anginosus is more abundant in the saliva and gut of people who have had a stroke and is associated with a higher risk of death and major cardiovascular events. Researchers compared 189 stroke patients with 55 non-stroke participants, finding that this

Researchers found that beneficial bacteria, such as Neisseria, are associated with improved memory and attention, while harmful bacteria like Porphyromonas correlate with mild cognitive impairment.These findings suggest that diet,

A research links physical contrast sensitivity deficiencies with schizophrenia.
Summary: People with schizophrenia experience impaired contrast perception, affecting their ability to differentiate light intensity and recognize shapes and textures. This deficit may stem from disruptions in glutamate neurotransmission, a key neural mechanism in the disease.Researchers suggest that contrast sensitivity testing could serve as a non-invasive biomarker for diagnosing and
