Cognition is a concept used in different ways by different disciplines, but is generally accepted to mean the process of thought. For example, in psychology and cognitive science it refers to an information processing view of an individual's psychological functions.
Many cognitive processes, such as decision-making, take place within seconds or minutes. Neuroscientists have longed to capture neuron activity during such tasks, but that dream has remained elusive -- until now.
Greater muscle strength is associated with better cognitive function in ageing men and women, according to a new Finnish study.
In the last decade, mounting evidence has linked seizure-like activity in the brain to some of the cognitive decline seen in patients with Alzheimer's disease.
New research shows that there are several interventions that could help prevent cognitive decline. According to the latest report entitled “Preventing Cognitive Decline and Dementia: A Way Forward,” from the National Academies of Sciences, Engineering, and Medicine (NASEM), cognitive training, increase in physical activity, control of blood pressure adequately among those with a high blood pressure are all fruitful measures to reduce cognitive decline. However evidence to support these three interventions is encouraging but insufficient to justify a public health campaign focused on their adoption.
According to a new study having sex frequently can boost brain power. The study from Oxford University was published today in The Journals of Gerontology, Series B: Psychological and Social Sciences.
In a landmark judgment, the Court of Justice of the European Union, yesterday ruled that courts could consider vaccines to be the reason for an illness despite the absence of any concrete evidence to support the connection.
Researchers can look into your eyes to determine whether you're getting your lutein, a pigment found in green leafy vegetables that is known to accumulate in the brain.
Potential new ways of understanding the cause of cognitive impairments, such as problems with memory and attention, in brain disorders including schizophrenia and Alzheimer's are under the spotlight in a new research review.
Radiation therapy using high-energy particles, like x-rays or electron beams, is a common and critical component in successfully treating patients with brain tumors, but it is also associated with significant adverse effects, such as neuronal loss in adjacent healthy tissues.
Even drinking moderate amounts of alcohol is associated with an increased risk of brain damage and impaired cognitive function, say researchers. Heavy drinking has previously been associated with adverse brain outcomes, but few studies have looked at whether moderate drinking also is.
A recent study conducted at Baycrest Health Sciences has uncovered a crucial piece into why playing a musical instrument can help older adults retain their listening skills and ward off age-related cognitive declines.
U.S. Asian populations may have different risk profiles for common geriatric conditions like cognitive and physical decline.
Long before symptoms of Alzheimer's disease become apparent to patients and their families, biological changes are occurring within the brain. Amyloid plaques, which are clusters of protein fragments, along with tangles of protein known as tau, form in the brain and grow in number, eventually getting in the way of the brain's ability to function.
Adolescents who are admitted to hospital for alcohol, drug, or violence related injuries are at a similar risk of suicide 10 years later than those who have self-harmed, according to a study using data from 1 million adolescents in the UK, published in The Lancet.
The 22q11.2 region of human chromosome 22 is a hotspot for a variety of birth defects. Scientists learned about this region because it is deleted in about 1 in 4,000 births, causing the loss or duplication of up to 40 genes.
Most people know that regular exercise can keep a body looking and feeling young. What about the brain?
In a new study, researchers at Lawson Health Research Institute and Western University are demonstrating that gait, or motion testing, while simultaneously performing a cognitively demanding task can be an effective predictor of progression to dementia and eventually help with earlier diagnosis.
The incidence of Alzheimer's disease (AD) is expected to triple in the coming decades and no cure has been found. Recently, interest in dietary approaches for prevention of cognitive decline has increased.
Scientists at the University of Sussex have started work on a multi-million pound project to develop drugs to treat the debilitating loss of cognitive function associated with Huntington's disease.
A newly published study from researchers at the New York University Langone Medical Center showed that brain training had significantly greater impact on improving cognition in patients with Multiple Sclerosis than the computer games used as an active comparison group.
