Hearing loss is often a symptom or outcome of other medical conditions (comorbidities), which can be very serious or even life-threatening. These are yet another reason not to ignore the symptoms of hearing loss. More than your hearing may be at stake.
Cardiovascular disease is one of the top causes of death. Poor cardiovascular health causes inadequate blood flow throughout your body, and one of the first signs of a problem is blood vessel trauma to your inner ear, resulting in damage to fragile hearing nerves. The outcome is hearing loss, particularly at the lower frequencies.The results of at least one major study showed a “significant association” between low-frequency hearing loss and dangerous outcomes of cardiovascular disease, including strokes, coronary artery disease, and heart attacks.
Despite the results of multiple studies linking hearing loss to the onset of dementia many people remain unaware that leaving hearing loss untreated poses a threat to cognitive health. The more profound the loss of hearing the greater the likelihood of cognitive decline. Hearing loss has also been associated with more rapid brain shrinkage, affecting areas of the brain responsible for processing speech, sound, memory, and sensory integration.
Theories as to why hearing loss a likely factor in the development of dementia in some patients point to straining to hear and understand despite hearing loss exhausting your mind and inhibiting its ability to function at peak performance. Also, If you cannot hear well you probably try to avoid social interactions requiring you to hold up conversation despite noise and crowds. Isolation is an established contributor to mental decline.
