Untreated sleep apnea has been linked to a long list of health risks. Now silent strokes - where the person doesn't know they had a stroke - can be added to that list.

Those recently suffering a lacunar stroke should talk to their health care provider about vitamin supplementation, studies suggest. 

Delirium among hospitalized stroke patients is common with up to 30 percent of patients suffering from disorientation and temporarily altered mental status. Research suggests those patients may have worse outcomes.

Developing memory loss as you age? The culprit for memory loss in some elderly patients may be linked to silent strokes that caused small pockets of dead brain cells.

Stem cell transplant patients may not only be at risk during treatment. A new study suggests that a decade later they are still more susceptible to psychological conditions and chronic illness.

Hypertension, diabetes and smoking  are known to increase your chances for stroke. A new study shows they can also be factors in developing cognitive problems later in life, even among patients who have never experienced a stroke.
