Aging

  Research examines the prevalence of abuse in older adults globally and in turn highlight the risk and need for increased protection services in this regard.   Elderly abuse continues to be a growing problem. In 2015 there were an estimated 901 million older adults, or adults over the age of 65, globally.  Psychological abuse

  A recent article, published in The American Journal of Clinical Nutrition, investigates how the metabolism of eicosapentaenoic acid (EPA) and arachidonic acid (AA) changes with age.   There are significant metabolic and biological changes that occur with progressing age. These changes must be taken into consideration to maintain a healthy and balanced nutritional intake.

Reducing maternal mortality rates has been a long-term goal of public health officials. In the past, the majority of research has focused on infant mortality and its relation to the mother’s age (maternal age), leaving the connection between maternal mortality rates and maternal age understudied. Recent research indicates that maternal mortality rates increase significantly after

Recent studies have identified an association between the height of an individual and their risk of various age-related diseases. Researchers investigated the relationship between adult height and healthy aging in a study population of female nurses and found that height has effects on healthy aging; they also found this association could be modified through dietary

Obesity is common among older adults and has been found to exacerbate age-related functional decline and contribute to frailty. Researchers found that the most effective strategy to elicit weight loss while maintaining physical function and preserving lean muscle mass and bone mineral density is a combination of aerobic exercise and resistance training in addition to

A cohort study in Japan investigated the relationship between eating citrus fruits and developing dementia later in life. The authors controlled for a number of confounding factors, and found that the consumption of citrus is linked with lower incidence of dementia.   Neurodegeneration leading to loss of cognitive function, generally referred to as dementia, is

Exercise is linked to a longer, healthier life but the mechanisms are unclear. To determine how exercise and health are linked, Tucker shows in Preventive Medicine that physical activity is associated with longer telomeres, which are linked to reduced cellular aging.   Exercise reduces the risk of many chronic diseases, including diabetes and hypertension, and

Diagnosis of mild-cognitive impairment (MCI) and, in many cases, the subsequent incident dementia in the elderly has proven to be difficult with current methods such as cerebrospinal fluid biomarker analysis. An article in JAMA Neurology discusses how a dual-task gait performance paradigm was used successfully as a diagnostic marker of progression to dementia in elderly

Researchers out of France and Monaco recently finished one of the longest and largest studies on Alzheimer’s disease. The study focused on using multidomain lifestyle intervention with Omega 3 supplementation for Alzheimer’s patients. The results, unfortunately, were insignificant, but do provide swaths of new data and show potential for new treatment approaches that are less

As demographics change in developed countries, a plethora of research is being done to better understand aging. The majority of research looks at how we can slow or (at least) improve the mental and physiological conditions of this inevitable process. Virtual reality is an exciting opportunity for older adults to escape their physical and mental

Within the health community, the use of medical marijuana is controversial.  Recently, a German-Israeli research team found evidence that small, controlled amounts of the active ingredient in marijuana, THC, improved cognitive function and memory in older mice.   Dementia is a general term used to describe cognitive decline in older people caused by damage to

As advances have been made in anesthetic and surgical techniques, patient outcomes following hip arthroplasties (hip replacements) have greatly improved. With these developments, formal physical therapy may no longer be necessary for patients, and self-directed therapy may be sufficient.   Total hip arthroplasty (total hip replacement) has undergone drastic advancements over the years that may

Music therapy is a promising tool in the treatment of Alzheimer’s and other neurodegenerative diseases. A new course offered by Ithaca College and a student organization provide music therapy to local nursing home residents. With so much enthusiasm for the course and organization, Ithaca College may start offering a Music as Medicine major or minor.

Age-related macular degeneration has no known treatment, and thus it is important to take preventative measures. The authors of a recent study investigate the relationship between α-linolenic acid (ALA) consumption and the risk of developing AMD.   Age-related macular degeneration (AMD) is a leading cause of vision loss in people over the age of 60.

A new study published in Neuropsychologia investigates the brain areas responsible for memory loss seen in neurodegenerative diseases like Alzheimer’s and dementia.   It has been well established in dementia patients that autobiographical memory (ABM) retrieval, the ability to remember information about yourself and personal experiences during the course of your lifetime, is compromised due to

A recently published study investigated whether low-density lipoprotein (LDL) cholesterol may have a causal relationship with Alzheimer’s disease, Parkinson’s disease, and dementia.   Cholesterol serves as a component in the myelin sheath, a protective layer for neurons. Patients taking drugs that lower levels of cholesterol, such as statins, may be at risk of developing neurological

Alzheimer’s disease is mainly caused by amyloid and neurodegeneration. A recent study shows several factors that may protect against the two main causes.   The two main factors most acknowledged to contribute to Alzheimer’s disease (AD) are amyloid, — when protein build up wreaks havoc in neurons, — and neurodegeneration. The most widely accepted model

Older adults who are hospitalized are at an increased risk of delirium, an impaired mental state with acute onset, which may increase their risk of in-hospital and post-discharge mortality. A recent study published in PLoS Medicine investigated whether mortality risk is greater among hospitalized older adults with delirium superimposed on dementia.   Delirium is characterized
