New research has identified changing levels of proteins in the blood which are associated with increasing mental impairment over time in people with Alzheimer's disease. The findings could ultimately help develop new drugs for the condition, by allowing better monitoring of the effects of drugs and improvements in clinical trials.

Early stage dementia patients referred to specialists are institutionalized twice as often as those who are not
A new epidemiologic study showed that patients with early stage dementia, who had been referred to a specialist, have twice the risk of institutionalization compared to those who are not, according to a research study published in the Journal of Alzheimer’s Disease this month. The research suggested the influence of early specialist referral for dementia patients on institutionalization risk and demonstrated that the benefits of early dementia diagnosis may lead to challenging issues.

Researchers led by Dr. Teppo Särkämö at University of Helsinki, Finland have revealed that caregiver-implemented musical leisure activities, particularly singing, are cognitively and emotionally beneficial especially in the early stages of dementia. The findings could help improve dementia care and better target the use of music in different stages of dementia.

Reproductive history and risk of cognitive impairment in elderly women: a cross-sectional study in eastern China
Researchers led by Professor Jun-Fen Lin at Zhejiang Provincial Center for Disease Control and Prevention have found that reproductive history, an important modifier of estrogen exposure across women’s lifetime, is associated with risk of cognitive impairment in postmenopausal women. These findings are published in the Journal of Alzheimer’s Disease.

Researchers at University College London (UCL) have revealed that a change in sense of humour could be an early sign of dementia. The findings could help improve dementia diagnosis, by highlighting changes not commonly thought to be linked to the condition. The study was funded by Alzheimer’s Research UK, the Wellcome Trust, Medical Research Council (MRC) and NIHR Queen Square Dementia Biomedical Research Unit. The research was published in the Journal of Alzheimer’s Disease on 10 November 2015.

A blood test developed at the University of North Texas Health Science Center detects pre-Alzheimer’s disease in asymptomatic Mexican-Americans with 96 percent accuracy. The test used blood samples provided by participants in the university’s Health & Aging Brain Among Latino Elders (HABLE) study. Hundreds of older Mexican-American residents from the Fort Worth area have participated in this study, which seeks to understand aging in this underserved population.

Chemical changes in brain cells caused by disturbances in the body’s day-night cycle may be a key underlying cause of the learning and memory loss associated with Alzheimer’s disease, according to a University of California, Irvine study. The research on mice, led by UCI biomedical engineering professor Gregory Brewer, provides the first evidence that circadian rhythm-altering sleep disruptions similar to jet lag promote memory problems and chemical alterations in the brain.

Neurocentria Inc., a clinical-stage biopharmaceutical company developing therapeutics to enhance brain function and correct cognitive impairment, announced the successful completion of a human study demonstrating that the company’s lead compound significantly reversed cognitive impairment in subjects 50 to 70 years old. The results have been published in the peer-reviewed Journal of Alzheimer's Disease.

Benzodiazepines and related drugs are initiated frequently in persons with Alzheimer's disease already before the diagnosis, and their use becomes even more common after the diagnosis, shows a recent study from the University of Eastern Finland. Benzodiazepines and related drugs are used as a sleep medication and for anxiolytic purposes. These drugs were initiated more frequently in persons with Alzheimer's disease than in persons not diagnosed with AD. Compared to persons not diagnosed with AD, it was three times more likely for persons with Alzheimer's disease to initiate benzodiazepine use after the diagnosis, and benzodiazepines were most commonly initiated six months after the diagnosis.

A new neuroimaging software, Neuroreader, was shown to be as accurate as traditional methods for detecting the slightest changes in brain volume, and does so in a fraction of the time, according to a research study published in the Journal of Alzheimer’s Disease this month. The research validates the software program that can be used for measuring hippocampal volume, a biomarker for detecting Alzheimer’s Disease.
