Biologically speaking, everything that makes you what you are depends on a three-pound organ inside your skull that is kept alive by the beating of an organ in your chest that weighs only 8 to 10 ounces. Your heart beats about 100,000 times a day, pumping 2,000 gallons of blood

This year, an estimated 800,000 people in the United States will suffer a stroke—some for the second or third time. Although 10 to 20 percent of strokes are fatal, seven million people in the United States are living proof that many survive the event. But these people are at greatly
Vascular dementia (VaD) ranks second among memory loss causes after Alzheimer’s disease, yet it is often overlooked. But what is vascular dementia?
The condition is caused by vascular problems affecting memory regions and supporting structures in the brain, and is closely associated with cardiovascular disease and cerebrovascular disease. Causes of vascular
Brain Scan May Spot Early Signs of Cognitive Decline
Although not yet clinically available, magnetic resonance imaging (MRI) scans to measure blood flow in the brain could one day detect signs of Alzheimer’s disease (AD) long before the disease process has caused serious brain damage. According to a report published online
For many patients, there is nothing “transient” about suffering a transient ischemic attack (TIA), an event that disrupts blood flow to the brain and causes symptoms much like those of a more severe stroke. These include difficulty with speech and vision, and numbness or weakness in the extremities and face,
Q: My mother has been diagnosed with mild cognitive impairment. Would she benefit from taking a medication for dementia?
A: Research involving nearly 4,500 older adults suggests that taking one of the four commonly prescribed medications for Alzheimer’s disease—rivastigmine (Exelon), donepezil (Aricept), galantamine (Razadyne) or memantine (Namenda)—does not improve the cognition of people
Many of us are unaware of a relatively common age-related health issue—cerebral microbleeds (CMB, largely symptomless leakage from miniscule blood vessels into surrounding brain tissue). Cerebral microbleeds have been linked to a decline in cognitive functions such as memory, thinking and information processing. The good news is that the condition
Women who suffer from the abnormal heart rhythm atrial fibrillation (AFib) are significantly more likely than men with the condition to be hospitalized for stroke, according to a new study. Other new research suggests that women with AFib are less likely than men to receive oral anticoagulant therapy. Could this
Shorter Sleep Duration Leads to Brain Aging
Missing out on your sleep makes your brain age faster, according to a study published in the July 2014 issue of the journal Sleep. Researchers examined data on 66 healthy adults aged 55 years and older who were participants in a long-term study of
Variable Blood Pressure and Cognitive Decline
A new study (Hypertension, May 23) suggests that fluctuations in blood pressure could put seniors at risk for faster cognitive decline. Researchers analyzed results from a five-year study including 976 people age 55 and older. Blood pressure variability was calculated from three or four visits
