Guest Blog: Hearing Loss and Dementia
Age related hearing loss is the most common form of hearing loss especially in the over 65s. While deteriorating hearing due to an aging system is an (unfortunate) natural process, factors such as family history of hearing loss, smoking, and certain medication, prolonged exposure to loud noise will have an impact on its rate of deterioration and resultant severity.
The human inner ear contains hair cells that help pick up information contained within sound waves. This information is then transmitted by way of the hearing nerve to the brain for further processing. As the body matures (or due to exposure to loud noise), hair cells can become damaged and/or die. The process can start as early as in a person’s 40s, but presents far more commonly in the over 65s and the over 70s. The body is unable to regenerate new hair cells, so there will eventually come a point when the person senses that their hearing isn’t what it used to be. (Although it is often friends and family members that notice the deterioration in hearing ability and alert the individual.)
There are common problems that the hard of hearing report; but how significant their impact on the person’s daily life will vary considerably across individuals.
Common symptoms include:
• Difficulty hearing people around you
• Frequently asking people to repeat themselves
• Frustration at not being able to hear
• Certain sounds seeming overly loud
• Problems hearing in noisy areas
• Problems telling apart certain sounds such as “s” or “th”
• More difficulty understanding people with higher-pitched voices
• Ringing in the ears
Loss of hearing and its likely cause can be established after attending a hearing test. The hearing exam or hearing test will cover a review of your medical history and a physical ear exam. If the hearing loss is age-related in nature, it is often managed through the use of hearing aids. There is no cure to undo the natural aging process that results in hair cell decline, so treatment should be viewed as a means to improve quality of life by managing the condition rather than curing it.
Those that willingly or unwillingly leave hearing loss unmanaged may face further longer term health complications, including depression, and perhaps surprisingly, cognitive and mental health decline.
There is a worrying link between hearing loss and dementia currently being explored. Recent research suggests that there is a connection between hearing loss and dementia. The hard of hearing are at a high risk of experiencing social isolation due to reduced communication with their immediate surroundings; and perhaps as a result of this, they are reportedly more likely to develop dementia.
An individual with hearing loss must concentrate harder to hear and often has to use lip reading and facial expressions to fill in the gaps as to what was said. After a while, this level of concentration can lead to fatigue and symptoms that mimic physical exhaustion. Some individuals may choose to simply avoid conversation, as it is too exhausting, thereby opening the door to social isolation.
If you have concerns about your hearing or the hearing of someone you care for, do arrange a simple and quick hearing test.

Guest Blog: Cognitive Issues in Seniors: Everything You Need To Know
In essence, mild cognitive impairment (MCI) is a condition in which an individual experiences a slight decline in mental abilities. While minor, the decline can be easily noticed by the person concerned or the people they interact with. The changes, however, are not severe enough to interfere with their routine activities and daily life.
Decline Due to Normal Aging vs. Mild Cognitive Impairment: What the Difference?
Gradual cognitive decline is sometimes evident with healthy aging. For instance, the mental processing slows down, the ability to learn new information is reduced, and the likelihood of getting distracted increases.
However, decline brought about by normal aging will not affect overall functioning or the ability to perform routine activities. Normal aging will also not affect intelligence, recognition, or long-term memory.
In normal aging, older people may forget names (and words) and misplace things occasionally. However, with mild cognitive impairment, the person forgets information and conversations one would usually remember, such as planned events and other appointments.
Does MCI Always Lead to Dementia?
Dementia is the general term used to describe the severe decline in mental function that interferes with daily living. There are instances, where a treatable disease or illness causes MCI.
However, researchers also discovered that for most patients with MCI, it is considered the point along the pathway to dementia. MCI can be secondary to various illnesses, including Parkinson’s and Alzheimer’s disease, vascular dementia, and frontotemporal dementia.
Is MCI Common?
According to the American Academy of Neurology, MCI is present in about 8 percent of people aged 65 to 69, in 15 percent of people aged 75 to 79, in 25 percent of those aged 80 to 84, and in about 37 percent of people aged 85 years or older.
Conclusion
If you suspect you have MCI, it is recommended that you see your doctor right away. While there is no specific test that can confirm a diagnosis, your doctor can tell if you have MCI based on the symptoms that manifest and the information you will provide.

Predicting Stroke Risk
Doctors know patients with atrial fibrillation are at a higher risk of having a stroke, and now a new study finds that integrating two separate clinical risk score models more accurately helps doctors assess the stroke risk of patients with Afib.
The composite stroke decision tool studied by researchers from the Intermountain Medical Center Heart Institute in Salt Lake City combines the widely used CHA2DS2-VASc with the Intermountain Risk Scores (IMRS) to derive and validate new stroke prediction scores.
The study shows the new model, IMRS-VASc, was significantly more effective in predicting stroke risk and will give clinicians a more effective and accurate tool to assess patients with cardiovascular disease.
Atrial fibrillation, the most common heart arrhythmia in the world, affects more than 2.7 million American adults. The abnormal heart rhythm causes blood to pool and clot in the heart, and when those blood clots break free, they can cause a stroke.
Researchers found that the new IMRS-VASc risk score model nearly doubles their ability to appropriately predict stroke risk compared to the traditional CHA2DS2-VASc risk tool. The development of the IMRS-VASc risk score model is the first step in a research pathway for other conditions that will ultimately result in time and cost savings for both patient and physician.
Researchers presented results from the study at the Heart Rhythm Society’s 39th annual Scientific Sessions in Boston earlier this month.
