Alzheimer's could possibly be spread via contaminated neurosurgery

Researchers have found that surgical instruments used for neurosurgery could get contaminated by the altered brain proteins that are seen in Alzheimer’s disease. These instruments are capable of spreading the condition if not treated or decontaminated properly before reuse.

			Episodic memory tests help in predicting brain atrophy and Alzheimer’s disease Use of two episodic memory tests help in predicting brain atrophy and Alzheimer’s disease, as indicated by a study carried out at the University of Helsinki and the University of California. Researchers suggest that comprehensive use of memory tests could improve the diagnosis of mild cognitive impairment due to Alzheimer’s disease.

			Researchers identify potential diagnostic tool for Alzheimer’s disease Researchers at Johns Hopkins Medicine have identified in live human brains new radioactive “tracer” molecules that bind to and “light up” tau tangles, a protein associated with a number of neurodegenerative diseases including Alzheimer’s disease and other related dementias.

	Researchers to study effects of electroconvulsive therapy on Alzheimer’s patients with aggression Researchers at McLean Hospital will lead a five-year study to investigate the use of electroconvulsive therapy to treat severe agitation and aggression in people with Alzheimer's disease.

	Study uncovers novel details about vulnerability of one brain cell to Alzheimer's Better tactics for detecting, preventing and treating Alzheimer's disease depend on a clearer understanding of cellular-level changes in the minds of patients, and a new study has uncovered novel details about the vulnerability of one type of brain cell.

	Alzheimer’s Disease and Calcium Supplements It is recommended that men and women between the age of 20 years and 50 years of age should obtain ~1000mg dietary calcium each day, with a daily upper limit of 2000-2500 mg depending on age and sex. Foods containing calcium include dairy products, leafy green vegetables, some small fish such as sardines, as well as fortified foods such as breakfast cereals.

	Air pollution linked with development of Alzheimer's in Mexico City children A new study by researchers at the Universities of Montana, Valle de México, Boise State, Universidad Veracruzana, Instituto Nacional de Pediatría and Paul-Flechsig-Institute for Brain Research heightens together with German company Analytik Jena concerns over the evolving and relentless Alzheimer's pathology observed in young Metropolitan Mexico City urbanites.

	Novel therapeutic targets based on biology of aging show promise for Alzheimer's disease A scientific strategy that explores therapeutic targets based on the biology of aging is gaining ground as an effective approach to prevent and treat Alzheimer's disease, according to research published in the December 7, 2018 online issue of Neurology.

	Reproductive cycle may provide new window into Alzheimer’s disease risk among women Female mice destined to develop Alzheimer’s-like pathology and related cognitive impairments display a unique pattern of fluctuation in sex hormones during the ovarian cycle, finds new research published in eNeuro.

	Breakthrough Alzheimer's discovery A new study has found that the neurons in the brain can alter their genetic make-up unlike other cells of the body which remain constant. This genetic modification could be the basis for altered protein formation and deposits. This can lead to several neurodegenerative conditions including Alzheimer’s disease, explain the researchers. The study was published in the latest issue of the journal Nature.

	Researchers are developing blood test to diagnose or predict Alzheimer's disease Today, the only way to definitively diagnose Alzheimer's disease in life is through brain scans and tests of cerebrospinal fluid that must be collected via lumbar puncture. Though cumbersome and expensive, such tests provide the most accurate diagnoses for patients.

	Researchers use brain connectome to reassess neuroimaging findings of Alzheimer's disease Already affecting more than five million Americans older than 65, Alzheimer's disease is on the rise and expected to impact more than 13 million people by 2050. Over the last three decades, researchers have relied on neuroimaging - brain scans such as magnetic resonance imaging (MRI) or positron emission tomography (PET) - to study Alzheimer's disease and other neurodegenerative diseases.

	Alzheimer’s Disease and Gingko Biloba Ginkgo biloba is a tree that is native to China and has been used in traditional Chinese medicine and cuisine for centuries. Extracts of Ginkgo biloba are often sold as food supplements with potential medicinal uses ranging from treating high blood pressure to altitude sickness.
