by Padmaja Sudhakar, University of Kentucky Credit: Pixabay/CC0 Public Domain The visual pathway is very long and goes from the eyes to the occipital lobe, which is the region in the cerebral hemisphere that processes vision. Since the visual pathway goes through the cerebral hemisphere on each side, stroke affecting certain areas of the cerebral...

One in three stroke survivors may suffer from a treatable condition
by American Heart Association The brain has about 100 billion cells called neurons. It’s made up of distinct parts, that developed though human evolution. Credit: American Heart Association In the first year following a stroke, upwards of 1 in 3 people will experience a treatable condition called spasticity that is described as muscle stiffness, pain and...
Training blood vessels may help protect against heart attack, stroke

Post-stroke memory loss can resolve for some patients
Memory loss is a common symptom after a stroke, but there’s hope for some that those memories could return. A new study from Norway examined 86 patients with relatively mild strokes and found many had improved mental functioning after 12 weeks. “Our study shows that around half of patients suffering a stroke had various forms of memory...
Oral contraceptives and hormone therapy increase the risk of stroke during the first year of treatment
by Uppsala University Credit: Unsplash/CC0 Public Domain A new study from Uppsala University shows that oral contraceptives and hormone therapy at menopause increase the risk of stroke. The increased risk is greatest during the first year of treatment and then declines. The study, which is now published in Stroke, is based on data from over a quarter...
Cutting-edge imaging yields new insights into stroke
by Greg Basky, Canadian Light Source Hemorrhage biomarkers provide insights into the extent of heme biotransformation during recovery as well as the extent of hemorrhage-induced oxidative damage. Credit: Metallomics (2022). DOI: 10.1093/mtomcs/mfac007 Hemorrhagic stroke, where a weakened vessel in the brain ruptures, can lead to permanent disability or death. Across the globe, over 15 million people are...
The drug gabapentin may boost functional recovery after a stroke
OHIO STATE UNIVERSITY COLUMBUS, Ohio – The drug gabapentin, currently prescribed to control seizures and reduce nerve pain, may enhance recovery of movement after a stroke by helping neurons on the undamaged side of the brain take up the signaling work of lost cells, new research in mice suggests. The experiments mimicked ischemic stroke in humans,...
Portable MRI can accurately detect most common form of stroke
By Rich Haridy April 20, 2022 A portable MRI machine effectively detected ischemic stroke in 45 out of 50 patients Hyperfine New research has found the world’s first portable MRI machine can accurately detect ischemic strokes. The machine was cleared for use by the US Food & Drug Administration (FDA) in 2020 and researchers are...
Stroke cuts life expectancy by one third
by University of Queensland Graphical abstract. Credit: Stroke (2022). DOI: 10.1161/STROKEAHA.121.038155 Almost two thirds of acute stroke patients fail to survive more than a decade and have high risk of recurrence, prompting researchers to call for better patient care. University of Queensland researchers analyzed data from more than 300,000 patients admitted to hospital following a sudden stroke...
Novel technology provides new path to prevent neuronal death due to stroke
by Anna Zarra Aldrich, University of Connecticut Graphical abstract. Credit: Neuron (2022). DOI: 10.1016/j.neuron.2022.03.021 Stroke is a leading cause of disability and death in the U.S., with roughly 800,000 Americans suffering a stroke every year. There are two kinds of stroke: ischemic and hemorrhagic. Ischemic stroke occurs when a blood clot forms and blocks blood supply to...
