Dr. Aimee Kao discusses key behaviors known to protect brain health. Dr. Kao looks at population trends and wonders if they tell a complete story. Watch full lecture here:
Even limited hearing loss might be associated with cognitive decline. If true, early intervention with hearing aids might help people have better cognitive performance.
Michael Johns III, MD, online editor for JAMA Otolaryngology, speaks with Justin Golub, MD, MS, assistant professor of otolaryngology at Columbia University, whose research has shown that very mild hearing loss can be associated with cognitive disability.
From a MedPage Today online article (April 2, 2020):
This relationship between higher glucose levels and poorer cognitive functioning extended beyond just CASI z-score, as well, Cukierman-Yaffe noted. Higher HbA1c levels were also tied to significantly poorer performance in other psychological tests, including the clock making test of executive functioning, test of discriminative ability, and for the test of verbal fluency.
Poorer glycemic control was tied to cognitive decline following a lacunar stroke in a prospective cohort study.
Among 942 individuals with type 2 diabetes who had a lacunar stroke, every 1% higher HbA1c was tied to a 0.06 drop in cognitive function at baseline measured by Cognitive Assessment Screening Instrument (CASI) z-score (95% CI -0.101 to -0.018), reported Tali Cukierman-Yaffe, MD, MSc, of Sheba Medical Center and the Sackler School of Medicine of Tel Aviv University in Israel.
In this Neuro Talk, Parkinson’s Foundation Chief Scientific Officer, Jim Beck, PhD, debunks common myths and misconceptions about Parkinson’s disease.
From a National Institute on Aging online release:
First place prize awarded to MapHabit: This mobile software provides behavior prompts with customizable picture and keyword visual maps to assist memory-impaired people with accomplishing activities of daily living. The care management platform employs different interfaces depending on whether the user is a person with impaired memory, caregiver or long-term care community manager. Caregivers can monitor adherence to medication schedules or track other activities.
MapHabit, Inc., is the first place winner of the Improving Care for People with Alzheimer’s Disease and Related Dementias Using Technology (iCare-AD/ADRD) Challenge, sponsored by the National Institute on Aging (NIA). The Atlanta-based MapHabit team, led by Stuart Zola, Ph.D., will receive the $250,000 first prize for their mobile device application that helps people with dementia follow simple commands to perform daily tasks, such as taking pills and brushing teeth, and also provides feedback to caregivers. NIA is part of the National Institutes of Health.

From a USC News online release:
The team found 85% of people first diagnosed with dementia were diagnosed by a non-dementia specialist physician, usually a primary care doctor, and an “unspecified dementia” diagnosis was common.
One year after diagnosis, less than a quarter of patients had seen a dementia specialist. After five years, the percent of patients had only increased to 36%.
In the first large study to examine the diagnosis of dementia in older Americans over time, researchers found the vast majority never meet with a dementia specialist and are instead overwhelmingly diagnosed and cared for by non-specialists.
The study, which also found the use of dementia specialty care was particularly low for Hispanic and Asian patients, was published Wednesday in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association.
From a Journal of the American Geriatrics Society release:
In our study, we found significant associations between baseline teeth symptoms and change in episodic memory. Deficits in episodic memory (ie, ability to retain new information) are most common in older adults with mild cognitive impairment making them more likely to progress to Alzheimer’s disease dementia.30 Furthermore, changes in episodic memory are often reported in older adults several years before the onset of dementia.
Our findings point to the importance of assessing oral health symptoms in this population. Developing policy measures aimed at ameliorating health and improving cognition in this high‐risk fast‐growing population in the United States would need to include oral health preventive and dental care services. Medical and dental care providers can identify problematic oral health symptoms as risk factors of cognitive decline. Outreach programs that target older adults to improve the awareness of these problems can then be developed. Dental care community outreach programs should focus their information on practical ways to prevent oral health problems and provide information on accessible treatment options.

From a The Telegraph online article:
A new study (in The Lancet, Aug 16, 2019) reveals that pensioners who have an operation have a one in 14 chance of suffering a silent or “covert” stroke – an event that shows no obvious symptoms but can damage the brain.
More than 1,100 patients across the world were given MRI scans nine days after some form of major non-cardiac surgery.
They were then followed up a year later to assess their cognitive abilities.
The researchers found that not only did having a silent stroke double the chances of cognitive decline a year on, it also increased the chances of a full life-threatening stroke.
Suffering a mini-stroke increased the risk of experiencing postoperative delirium as well.
