Research on dementia and cognitive decline. Covers Alzheimer's screening, brain injury recovery, attention training, and gaps in diagnosis and care.
A study of 1,709 individuals found that those who drank wine weekly or monthly had a significantly lower risk of developing dementia. Flavonoids, natural compounds with antioxidant effects, may be responsible for this beneficial effect.
A recent study suggests that shunting cerebrospinal fluid may help slow cognitive decline in patients with Alzheimer's disease. In a small, controlled trial, patients with Alzheimer's and normal pressure hydrocephalus experienced relative stability compared to those without shunts.
Patients with post-stroke dementia are at an increased risk of death within two years, with a relative risk of mortality six-fold compared to those without dementia after stroke. Dementia is also associated with poorer survival rates and reduced treatment adherence due to medication non-compliance.
A recent study reveals that feeding tubes do not necessarily improve the quality of life for patients with severe dementia. The study analyzed data from over 385,000 nursing home residents and found that states with higher rates of
Researchers found a link between abnormal retinal blood vessels and cognitive decline, potentially providing an early warning system for dementia. Low vitamin C levels in the blood were also associated with increased stroke risk, particularly among hypertensive men.
A study by Dr. Anne B. Newman found that people with cardiovascular disease have a 30% increased risk of dementia, primarily due to vascular dementia caused by insufficient blood flow to the brain. Preventing cardiovascular disease may be an effective measure for preventing dementia in older adults.
Researchers found that Parkinson's patients who developed dementia had a significantly higher risk of death, regardless of hallucination or depression status. The study also revealed that incident dementia and disease severity were independently associated with an increased risk of mortality.
A new study found that galantamine improves cognition and daily living activities in patients with vascular dementia. The medication was also shown to reduce symptoms of behavioural changes, providing a potential treatment option for patients with limited pharmacological help.
A first-of-its-kind clinical study presented at the AAGP meeting shows that treatment with ARICEPT significantly improved cognitive and global function in patients with vascular dementia. The study, which included 616 patients, found improvements in both cognitive abilities and overall functioning.
Elevated homocysteine levels are strongly linked to increased risk of dementia and Alzheimer's disease, doubling the chance of developing AD. The study found that consistently high homocysteine levels throughout the period of the study were at highest risk for dementia and AD.
A 24-week study found patients with vascular dementia taking ARICEPT experienced significant cognitive and global function improvements compared to placebo. The medication was well-tolerated, even when taken with other medications, according to the researchers.
A Dutch study suggests that moderate alcohol consumption may reduce the risk of dementia among older individuals. The research found a significant association between light-to-moderate alcohol intake and a lower risk of developing dementia, as well as vascular dementia.
Researchers investigate the effects of musical training on young children's verbal and writing skills, as well as its potential benefits for older adults' cognitive preservation. The study, led by Dr. Christo Pantev, aims to uncover how musical training modifies brain development and its life-enhancing effects in the elderly brain.
Participation in leisure activities such as reading and socializing reduces risk of dementia by 38%. Intellectual activities show highest risk reduction, with an additional 8% benefit per activity engaged. High education and occupation levels also previously linked to reduced AD risk.
Research found moderate alcohol intake reduces risk of cognitive impairment in elderly individuals, particularly those consuming less than 40g daily. Conversely, high levels of alcohol consumption increase the risk of cognitive dysfunction.
Recent research from San Francisco Veterans Affairs Medical Center suggests a closer connection between HIV and Alzheimer's disease. The study found that immune cell markers of AIDS dementia remain even after treatment with anti-retroviral drug cocktails, similar to those elevated in patients with Alzheimer's disease.
A study by Ohio State University found that former caregivers continue to show levels of depression and loneliness similar to current caregivers even three years after their spouse's death. The negative effects of long-term caregiving for a spouse with dementia may persist beyond the caregiving years.
A recent Indiana University study found that nearly one in four older African Americans have measurable cognitive problems, with prevalence increasing with age. Researchers also discovered that a significant proportion of those with cognitive impairment may progress to dementia within 18 months.
A study of African-American residents aged 65 and older found that 23% had cognitive impairment without dementia, with rates increasing with age. The majority of cases lacked a medical cause, suggesting potential transient nature
A study published in Neurology found that cognitive impairment No Dementia (CIND) affects 23.4% of community-dwelling participants aged 65 and older, with rates increasing by 10% for every 10 years after age 65.
A University of Michigan study found that older Americans with dementia receive substantially more informal help than those with normal cognitive function. The analysis estimated the additional time and associated costs of providing informal care to be $18 billion annually.
Patients with dementia in the middle stages are five times more likely to experience intense emotional distress than those in early or late stages. The study found that caring for personal hygiene, particularly invasive care, triggers acute distress. Strategies like supervision and environmental changes can help mitigate reactions.
The [18 F]FDDNP PET scan revealed longer retention times of the tracer in areas with high densities of ß-amyloid senile plaques. This finding provides valuable insights into Alzheimer's disease (AD) progression. The image is expected to shed light on disease mechanisms and potential therapeutic targets.
Researchers found that frontotemporal dementia patients shifted from disliking classical music to appreciating Italian pop, and another patient discovered a taste for pop music after losing interest in her children. The study suggests that novelty-seeking behavior may play a role in these changes.
A study found that people with late-onset dementia had lower intelligence scores as children compared to those without the disease. The researchers identified 59 patients with early-onset dementia and a comparison group, suggesting that lower childhood intelligence may be a risk factor for late-onset Alzheimer's disease.
Researchers analyzed medical records of World War II veterans with head injuries and found a link between early adulthood trauma and later-life Alzheimer's disease. The more severe the injury, the greater the risk of developing AD, with those with severe injuries having a four-fold greater risk.
Patients with dementia often receive inadequate medical care due to a lack of data on the safety and efficacy of treatments. Guidelines need to consider a patient's ability to comprehend, remember, and follow directions, as well as their caregiver's capacity to listen and act.
A new study finds that men with high blood pressure, weight and cholesterol levels in their 50s are more likely to develop vascular dementia in their late 70s. The research suggests that reducing these risk factors may help delay the onset of dementia, but more large-scale studies are needed to confirm the findings.
Studies found dementia patients had significantly longer hospital stays than those without the condition, translating to higher costs. Early detection of dementia is crucial in reducing treatment costs and improving patient outcomes.
A new study links traumatic stress disorder and dementia in WWII veterans, suggesting that painful war memories may trigger violent episodes. Researchers found that veterans who developed dementia showed no signs of PTSD until then, highlighting the need for further research into this phenomenon.
A study published in Neurology found that high blood pressure is associated with a higher risk of severe cognitive decline, particularly in those with untreated or uncontrolled hypertension. The study suggests that controlling high blood pressure may help prevent or delay dementia.
A study by Oregon Health Sciences University found that healthy older adults lose brain tissue at a relatively constant rate, not accelerating with age. The research suggests that it's possible to age normally without a rapid decline in brain health.
Researchers propose that HIV's passive infection of astrocytes may contribute to AIDS dementia by disrupting glutamate removal. The study found more apoptotic astrocytes in brains of people with dementia compared to those without, suggesting a potential new target for prevention and treatment.
Researchers discovered a gene-toxin link that may increase the risk of dementia in Parkinson's patients. The study found that exposure to pesticides and a defective gene called CYP 2D6 29B+ increased the likelihood of developing dementia, particularly among those with Parkinson's disease with dementia (PD+D).
Macrophages may proliferate in response to HIV integration, causing disease through sequential pathogenesis. Researchers identify potential DNA-interacting drugs to treat AIDS dementia.
A new study suggests that cognitive tests can predict which older adults will develop Alzheimer's disease or other dementia. Those who scored poorly on the tests were 11 times more likely to show symptoms of dementia two years later than their healthy counterparts.
Researchers at Johns Hopkins Medicine discovered a link between nitric oxide levels and the severity of AIDS dementia. The study found that high levels of nitric oxide synthase in the brains of patients with advanced HIV infection led to brain cell destruction, affecting 20% of those affected.
A new study finds that first and second generation Japanese-American men living in Hawaii have a higher risk of Alzheimer's disease compared to European-ancestry Americans. The study also notes that rates of vascular dementia remain unchanged in this population.
