Magnetic Resonance Imaging, often referred to as MRI, is a term you’ve probably come across before, but the inner workings of this advanced medical technology might seem like a puzzle. With roughly 30 million MRI scans performed every year in the United States, MRI is the third most commonly used imaging technique after X-rays and computed tomography (CT) scans, and the second most used neuroimaging technique after electroencephalography (EEG). Don’t let these jargon-heavy terms intimidate you – by the end of this blog post, you will have a better understanding of how MRI works. So bear with me and think of me as your friendly guide in unraveling this captivating yet intricate subject.
In Canada, 38% of adults between the age of 20 and 79 years old suffer from hearing loss, and many never receive treatment. Furthermore, scientists have found that hearing loss often precedes diagnoses of age-related dementia by 5 to 10 years, suggesting that difficulty in hearing may contribute to cognitive decline – an interesting link that is supported by imaging studies showing functional and anatomical changes in the brains of older adults.
Aging is a normal part of life, and just like the rest of the body, the brain changes as we get older. In normal aging, most people will eventually experience some changes in the way they think, like slower processing speeds or certain types of memory loss, although skills and knowledge tend to remain stable or are even improved over time.
