Study proves that postural orthostatic tachycardia syndrome may be an autoimmune disorder

The symptoms of postural orthostatic tachycardia syndrome, or POTS, can be as varied as they are confounding. There can be fatigue, pain, bleeding disorders and anxiety. Heart palpitations and lightheadedness are common.

African American women have greater risk of stroke, death during pregnancy and childbirth

African American women have a significantly increased risk of stroke and death during pregnancy and childbirth or in the period right after birth, compared to the risk of stroke among white women, according to preliminary research to be presented at the American Stroke Association's International Stroke Conference 2021.

Neuroprotectant-loaded nanoparticles may reduce stroke severity, improve survival

When NA1, a neuroprotectant, was delivered to the brain in nanoparticles, it reduced stroke severity and improved survival in a mouse model of stroke, according to preliminary research to be presented at the American Stroke Association's International Stroke Conference 2021.

Depression risk higher among stroke survivors, especially female patients

Stroke patients were nearly 50% more likely than heart attack patients to develop depression, and female stroke patients had a higher risk of depression than their male counterparts, according to two preliminary studies by the same research group to be presented at the American Stroke Association's International Stroke Conference 2021.

Dementia risk escalates with the number and severity of strokes

Having an ischemic stroke increases dementia risk, and that risk escalates with the number and severity of strokes, according to preliminary research to be presented at the American Stroke Association's International Stroke Conference 2021.

Higher historic redlining scores associated with greater rates of stroke

Discriminatory housing policies that restricted the sale or purchase of homes by race in certain neighborhoods across the U.S., called 'redlining,' which were established nearly a century ago and outlawed by the Fair Housing Act of 1968, were associated with higher rates of stroke in the same neighborhoods in 2017, according to preliminary research to be presented at the American Stroke Association's International Stroke Conference 2021.

A retinal photo may provide early warning signs of stroke and dementia

Pictures of the retina may someday provide early warning signs that a person is at an increased risk of stroke and dementia, making it possible to take preventive measures, according to preliminary research to be presented at the American Stroke Association's International Stroke Conference 2021.

Black Medicare patients with ischemic stroke die at a higher rate than white patients

A long-term look at Medicare patients shows that Black patients who have an ischemic stroke (blocked blood flow to the brain) die at a higher rate than white patients, even after accounting for preexisting health conditions, according to preliminary research to be presented at the American Stroke Association's International Stroke Conference 2021.
