Case Western Reserve University School of Medicine researchers have identified a new biomarker for sporadic Creutzfeldt-Jakob disease (sCJD), a degenerative brain disease with no cure. The biomarker, transferrin, shows promise in early diagnosis and potential therapy development.
Researchers have identified a new biomarker for sporadic Creutzfeldt-Jakob disease, which can accurately diagnose the condition in patients while they are still alive. 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.
Research analyzed 15 studies and found that stroke survivors with atrial fibrillation were 2.4 times more likely to develop dementia than those without the heart condition. Approximately 25% of patients with stroke and atrial fibrillation developed dementia during follow-up.

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.

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 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.

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 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 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 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 mild memory changes are caused by brain lesions associated with Alzheimer's and other dementias, contradicting the long-held notion that age is a primary factor. The study involved over 350 participants and showed a rapid decline in cognitive function in the last four to five years of life.
Researchers found that NGP 555 selectively targets gamma secretase, reducing Aβ42 and amyloid pathology in a transgenic mouse model. Chronic administration led to significant reduction in diffuse and neuritic plaques without GI side effects.
Researchers from the University of Edinburgh are studying proteins to understand how they clump together with age, a process linked to several conditions. The goal is to design drugs to prevent this aggregation, which causes brain plaques in Alzheimer's and cloudy vision in cataracts.

A new study published in Neurology shows that mild cognitive impairment (MCI) is 1.5 times higher in men compared to women. MCI often leads to Alzheimer's disease and the study found nearly 14% of participants had MCI, with men being more likely to experience it.
A pivotal study finds a strong association between post-traumatic stress disorder (PTSD) and an increased risk of dementia in veterans. The research, published in the Journal of the American Geriatrics Society, suggests that PTSD may be an early marker of dementia or contribute to cognitive impairment.
A new study has identified three factors linked to cognitive deficits in type 2 diabetes: high blood pressure, balance issues, and poor health reports. These factors contribute to weaker memory and slower cognitive processing in individuals with Type 2 diabetes.
Researchers discovered that mentally stimulating activities like crossword puzzles and reading may slow initial cognitive decline but accelerate dementia progression in older age. People with more active lifestyles tend to experience faster declines once diagnosed with dementia.
