Adequate levels of vitamin E critical for young, elderly and pregnant women

Amid conflicting reports about the need for vitamin E and how much is enough, a new analysis published today suggests that adequate levels of this essential micronutrient are especially critical for the very young, the elderly, and women who are or may become pregnant. [More]
Discovery reveals promising target for treatment of end-stage heart failure

Discovery reveals promising target for treatment of end-stage heart failure

As a heart fails, losing its ability to squeeze blood through the circulatory system, the body releases a neurohormone that interferes with the heart's best chance to improve contractility, a team of Temple University School of Medicine researchers show in a study published September 9th in the American Heart Association journal, Circulation.

New way to preserve flexibility and resilience of the brain

New way to preserve flexibility and resilience of the brain

As Alzheimer's disease progresses, it kills brain cells mainly in the hippocampus and cortex, leading to impairments in "neuroplasticity," the mechanism that affects learning, memory, and thinking. [More]
Stages of symptoms in schizophrenia: an interview with Dr. Mark Opler, ProPhase

Stages of symptoms in schizophrenia: an interview with Dr. Mark Opler, ProPhase

I think there's a perception that schizophrenia is principally a disorder that involves hallucinations such as hearing voices, seeing things and believing things that aren't real. These are indeed part of the phenomenon, but the condition is much broader than that. [More]

Cognitive impairment communication: an interview with Marc Wortmann, Executive Director, Alzheimer’s Disease International (ADI)

Cognitive impairment is the loss of brain functions like short and long term memory, the ability to plan ahead or conduct more complicated intellectual tasks. [More]
People with cognitive impairment are more likely to have stroke

People with cognitive impairment are more likely to have stroke

People with cognitive impairment are significantly more likely to have a stroke, with a 39% increased risk, than people with normal cognitive function, according to a new study published in CMAJ (Canadian Medical Association Journal). [More]
Higher-fit children have more compact white-matter tracts in the brain than lower-fit peers

Higher-fit children have more compact white-matter tracts in the brain than lower-fit peers

A new study of 9- and 10-year-olds finds that those who are more aerobically fit have more fibrous and compact white-matter tracts in the brain than their peers who are less fit. "White matter" describes the bundles of axons that carry nerve signals from one brain region to another. More compact white matter is associated with faster and more efficient nerve activity. [More]
Study suggests mental illness doesn't preclude enjoying life

Study suggests mental illness doesn't preclude enjoying life

Schizophrenia is among the most severe forms of mental illness, yet some people with the disease are as happy as those in good physical and mental health according to a study led by researchers at the University of California, San Diego School of Medicine. [More]
Patients who rely on pacemakers and defibrillators run risk of serious health complications

Patients who rely on pacemakers and defibrillators run risk of serious health complications

Patients who rely on pacemakers and defibrillators to maintain a normal heart rhythm run the risk of serious health complications if they don't fully understand how the devices work and what to do when they experience an irregular heartbeat. [More]
New therapeutic strategy to combat common genetic risk factor for ALS, FTD

New therapeutic strategy to combat common genetic risk factor for ALS, FTD

A team of researchers at Mayo Clinic and The Scripps Research Institute in Florida have developed a new therapeutic strategy to combat the most common genetic risk factor for the neurodegenerative disorders amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease) and frontotemporal dementia (FTD).

People who develop depression, MCI after age 65 are more vulnerable for accelerated brain aging

People who develop depression, MCI after age 65 are more vulnerable for accelerated brain aging

People who develop depression and mild cognitive impairment (MCI) after age 65 are more likely to have biological and brain imaging markers that reflect a greater vulnerability for accelerated brain aging, according to a study conducted by researchers at the University of Pittsburgh School of Medicine. The findings were published online in Molecular Psychiatry. [More]

Study shows noticeable differences in brain function across the day for older adults

Older adults who are tested at their optimal time of day (the morning), not only perform better on demanding cognitive tasks but also activate the same brain networks responsible for paying attention and suppressing distraction as younger adults, according to Canadian researchers. [More]
Anti-cholinergic drugs could be responsible for decline in cognitive, physical function in elderly patients

Anti-cholinergic drugs could be responsible for decline in cognitive, physical function in elderly patients

Drugs widely prescribed to the elderly could be responsible for a decline in cognitive and physical function according to research from the University of East Anglia and the Regenstrief Institute. [More]
