The biomarker, transferrin, is significantly decreased in the cerebrospinal fluid of patients with sCJD before the end stage of the disease.
Researchers found a delay in detecting CADASIL, a vascular brain disorder, and diagnosed it as multiple sclerosis in some patients. The study suggests that CADASIL often goes misdiagnosed due to similarities with MS in brain MRIs and symptoms.
Research by University of East Anglia shows stroke survivors with irregular heartbeat are 2.4 times more likely to develop dementia than those without the heart condition. Atrial fibrillation increases the risk of stroke and dementia in patients with stroke.

The study found a significant link between the two conditions, with the risk of developing dementia increasing by twofold, threefold, and fivefold for individuals with mild, moderate, and severe hearing loss.
Researchers emphasize the importance of financial planning for Alzheimer's patients, noting that doctors often fail to address this critical issue. Early guidance on managing finances is essential, allowing caregivers to take over responsibilities and maintaining patient autonomy.
A study of 639 individuals aged 36-90 found a significant association between hearing loss and dementia. The risk of dementia increased among those with moderate or severe hearing loss, particularly in older adults, who experienced nearly one-third more risk due to hearing loss.
Researchers developed a new mode of dementia care that significantly reduces emergency department visits and hospitalizations, while encouraging the use of non-harmful medications. The model results in improved health outcomes, reduced healthcare costs, and less emotional burden on family caregivers.
Hippocampal sclerosis (HS-AGING) is a serious condition causing cognitive decline and impaired memory in aged persons. Researchers analyzed autopsy data from 1,100 individuals to define HS-AGING as a distinct disease entity.
A study found that for-profit hospices tend to have more patients with dementia and other diagnoses requiring less intense care, as well as longer hospital stays. This may be due to financial incentives tied to Medicare reimbursement rates.
A new study found that traditional dietary surveys, relying on self-reported data, are inconsistent and can be influenced by memory impairment and digestive issues. Using nutrient biomarkers through blood tests, researchers aim to improve the accuracy of nutritional assessments and develop more effective therapies for cognitive health.

A study found that lower levels of beta-amyloid protein fragments, combined with less education, are associated with a faster rate of cognitive decline over nine years. Cognitive reserve measures modified the association, with those having higher reserves showing less decline.
A large proportion of Medicare expenditures for nursing home residents with advanced dementia is spent on aggressive treatments that may be avoidable and of limited clinical benefit. Strategies that promote palliative care may reduce costs at the end of life by shifting from aggressive to comfort care approaches.
Researchers at Mayo Clinic have identified a gene variant that appears to protect against frontotemporal lobar degeneration (FTLD) in high-risk individuals with progranulin mutations. The study found that carrying two copies of the protective TMEM106B allele delays or prevents FTLD onset, suggesting it may increase progranulin levels.
A new study finds that the proportion of nursing home residents with dementia benefiting from Medicare hospice care nearly tripled between 1999 and 2006, with duration of care more than doubling. This trend has implications for policymakers seeking to control Medicare costs while preserving access to essential end-of-life care.
A study of 1,130 older adults found that high levels of 'good' cholesterol (HDL) were associated with a decreased risk of both probable and possible Alzheimer's disease. Higher plasma HDL cholesterol was also linked to lower risks despite other factors.
A study of 614 vineyard workers in South West France found a link between long-term pesticide exposure and declining cognitive abilities, including lower scores on memory and recall tests. The researchers suggest that higher risks of dementia may be associated with pesticide exposure.

A new study has uncovered the role of Sortilin in regulating Progranulin levels in neurons, which may hold promise for treating frontotemporal lobar degeneration (FTLD) and amyotrophic lateral sclerosis (ALS). The research found that Sortilin-mediated PGRN endocytosis is a key pathway underlying FTLD-TDP pathophysiology.

The study found strong associations between genetic variants in the same region of chromosome 1 and plasma progranulin levels.
A national survey found that palliative care for patients with dementia has increased, but gaps in coverage and inadequate insurance coverage remain. Interdisciplinary teams, community partnerships, and education are critical strategies for successful palliative care and reducing caregiver burden.
A study of 90 patients with bullous pemphigoid found that nearly half had at least one neurologic disease, including cerebrovascular disease and dementia. The condition was often diagnosed after the neurologic disease, suggesting a potential predisposition.
A new study published in Neurology found that middle age women whose cholesterol levels decline are at a 2.5 times greater risk of developing Alzheimer's disease and other forms of dementia than those whose cholesterol stayed the same or increased over time.
A new study suggests that mid-life cholesterol levels may not be linked to the development of Alzheimer's disease, but large decreases in cholesterol in old age could be a better predictor. After 32 years, women with the greatest decline in cholesterol were more than twice as likely to develop dementia.
A new screening test, Sweet 16, can detect dementia in elderly patients more rapidly, providing an alternative to the Mini-Mental State Examination. The tool has been shown to accurately characterize mental status without influencing patient education or sociodemographic factors.
Researchers at King's College London found a correlation between VGLUT1 protein levels and cognition scores in individuals with and without dementia. Preserving VGLUT1 artificially after a stroke may reduce the risk of developing vascular dementia.

Dr. Charles DeCarli, an international leader in neuroimaging, has received the 2010 J. Allyn Taylor International Prize in Medicine for his groundbreaking research on imaging of the aging brain and its connection to vascular diseases.
A large cohort study found that heavy smoking in middle age was associated with a higher risk of developing Alzheimer's disease and vascular dementia. The study, published in Archives of Internal Medicine, suggests that smoking may affect the development of dementia through both vascular and neurodegenerative pathways.
A Kaiser Permanente study found that heavy smoking in midlife is associated with a 157% increased risk of Alzheimer's disease and a 172% increased risk of vascular dementia. Vascular dementia is caused by conditions affecting the blood supply to the brain.
A new study reveals that 70-year-olds born in 1930 performed better in cognitive tests than their predecessors born in 1901-02. The study attributed the improvement to better pre- and neonatal care, nutrition, education, and access to advanced technology. Despite this, memory problems remained a predictor of dementia risk.
A study published in Neurology found that walking at least 72 blocks per week can increase gray matter volume and reduce cognitive impairment. Regular exercise in midlife may improve brain health and thinking abilities in later life.
