Dementia, Alzheimer’s Disease May Be Easily Identified Through Simple Number Test That Screens for Cognitive Impairment

A simple number naming test can identify those with cognitive impairment among elderly individuals, clearly differentiating patients with dementia and people with mild cognitive impairment from cognitively healthy people. The study, “Screening Utility of the King-Devick Test in Mild Cognitive Impairment and Alzheimer Disease Dementia,” published in…

Long-term Moderate Chocolate Consumption Appears to Lower Risk of Cognitive Decline in Older People, Study Reports

Chocolate consumption may protect older people from cognitive decline, possibly preventing the development of Alzheimer’s disease, according to Portuguese researchers at the Institute of Molecular Medicine. However, researchers cautioned this is only true for people who drink an average of less than one espresso per day. The study, “Chocolate…

Alzheimer’s Therapy Candidate Bryostatin Generates New Synapses in Mouse Brains, Study Shows

Neurotrope Bioscience’s lead Alzheimer’s drug candidate, bryostatin, promotes the formation of new synapses in the brains of mice, according to the study, “PKC epsilon Promotes Synaptogenesis through Membrane accumulation of the Postsynaptic Density Protein PSD-95,” recently published in the Journal of Biological Chemistry. Synaptogenesis and synaptic maturation are two…

Cannabinoids, Like Those in Marijuana, May Protect Alzheimer’s Patients from Plaque Buildup

Alzheimer’s disease has been described in medical literature for more than a century, but still has no effective treatments. Now, scientists at the Salk Institute in La Jolla, California, report finding evidence that tetrahydrocannabinol (THC), one of several physiologically active chemical compounds in marijuana, can promote cellular removal of amyloid beta, a toxic…

Alzheimer’s Disease First Steps Revealed by Mouse Brain in a Dish

Using slices of mouse brain tissue kept alive in a lab dish, scientists have identified the earliest molecular changes leading to Alzheimer’s disease. The findings, showing how early alterations in brain amyloid-β balance causes nerve connections called synapses to die, might allow scientist to target the mechanisms and develop therapies to…
