Problems with brain's waste clearance may increase risk of dementia: Study

An impaired movement of the brain's cerebrospinal fluid, which helps remove waste, could explain how poor sleep and heart conditions can increase one's risk of dementia, according to a study. Other functions of the cerebrospinal fluid include cushioning the central nervous system from shocks and delivering nutrients. The colourless fluid is part of the glymphatic system. Researchers led by those at the UK's University of Cambridge said the glymphatic system is considered important for protecting one against varied common forms of dementia, including Alzheimer's disease in which proteins called amyloid clump up and form toxic 'plaques'. Dementia is a neurodegenerative disorder in which memory, speech and thought processes are steadily affected with age, and can eventually disrupt daily activities. The study, published in the journal Alzheimer's and Dementia: The Journal of the Alzheimer's Association, looked at whether a disorder of the brain's small blood vessels -- which affects .

Rapid health reforms, new treatments required to tackle Alzheimer's: Study

A rapid reform to healthcare systems, public policy and attitude in society would be required to address burden of Alzheimer's disease in population, even as medications and blood tests present a potential in diagnosis and treatment, researchers say in a Lancet Series. Alzheimer's disease -- the most common form of dementia -- is an ageing-related neurological disorder which steadily impacts one's memory and thought processes, eventually interfering with daily activities. Describing new treatments and diagnostic methods for the condition in a series of three papers in The Lancet journal, the international team of researchers said that medications -- lecanemab and donanemab -- could slow down Alzheimer's disease from advancing. The drugs, which target specific proteins in a cell, have shown an efficacy comparable to that of drugs for cancer and autoimmune disorders such as rheumatoid arthritis and multiple sclerosis, the team said. They added that however, high costs of medicines, .

Loneliness increases risk of dementia by over 30%, studies review suggests

Loneliness is a major risk factor that increases the risk of dementia by over 30 per cent, regardless of age or gender, a review of 21 long-term studies involving over six lakh participants worldwide has found. Loneliness, which involves one feeling dissatisfied with their social relationships, was also linked with symptoms preceding the stage of being diagnosed with dementia, such as cognitive impairment or decline. Both conditions affect decision-making, memory and thought process. However, dementia's symptoms are severe enough to interfere with one's daily functioning. The psychological state of feeling disconnected from society is now widely regarded as a risk factor for ill-health, even though studies have shown that loneliness cannot directly cause the disease. "Dementia is spectrum, with neuropathological changes that start decades before clinical onset. It is important to continue studying the link of loneliness with different cognitive outcomes or symptoms across this ...

Feeling lack of purpose, personal growth could be signal of dementia: Study

The feeling that one's life lacks purpose and that there are fewer opportunities for personal growth could be a very early sign of dementia, according to a study. Researchers found that among older adults, these aspects of psychological wellbeing noticeably declined three to six years before a diagnosis of mild cognitive impairment, in which one's memory and thinking is affected, yet not to the extent that it interferes with their daily functioning. Mild cognitive impairment is often seen to precede dementia, in which the symptoms become severe enough to interfere with daily activities. The researchers, including those at China Agricultural University's Department of Nutrition and Health, said that while there is mounting evidence linking psychological well-being to brain ageing and related disorders, such as dementia, much of it focuses on the aspect of one's sense of purpose and not others, including personal growth. For the study, published in the Journal of Neurology Neurosurge

Hearing aids may reduce cognitive decline in adults: Lancet study

Hearing aids may protect against cognitive decline in older adults at greater risk of dementia, according to a study published on Tuesday in The Lancet journal. The findings are based on the first randomised controlled trial (RCT) of its kind involving nearly 1,000 older adults from multiple locations across the US. "These results provide compelling evidence that treating hearing loss is a powerful tool to protect cognitive function in later life, and possibly, over the long term, delay a dementia diagnosis," said Professor Frank Lin of Johns Hopkins University School of Medicine and Bloomberg School of Public Health, US. "But any cognitive benefits of treating age-related hearing loss are likely to vary depending on an individuals' risk of cognitive decline," said Lin. Age-related hearing loss is extremely common, affecting two-thirds of adults aged over 60 globally, the researchers said. However, less than 1 in 10 individuals with hearing loss in low- and middle-income countries
