Surprising Causes of Alzheimer’s Disease

A recent World Alzheimer Report by the ADI (Alzheimer’s Disease International) estimates that more than 35 million people across the globe have dementia. The report also predicts that the number will almost double by the year 2030. Slightly over 5.1 million Americans also have Alzheimer’s disease, and this is according to statistics from the AFA (Alzheimer’s Foundation of America). This reliable data from reputable institutions shows the high prevalence of the condition, but scientists and experts do not seem to agree on the main causes. However, some surprising things have been proven to trigger this condition. Here are some of these unexpected causes of Alzheimer’s disease.


A healthy and fulfilling life is about engaging with friends and people in your community. Humans are social beings, and this fact alone is enough to show that it is not a good idea to seclude oneself because it means that you will lead a lonely life. One study published in the Journal for Neurology, Neurosurgery and Psychiatric identified that there is a close link between loneliness and the onset of dementia. According to the study, the feeling of isolation increases one’s likelihood of getting dementia by up to 1.63 times.

Sleep Deprivation

Most people do not give sleep the importance that it deserves, and they will in many instances sacrifice it in an attempt to have more time for other things such as hobbies, fun, and career. However, this is a big mistake and it comes with severe health implications. Aside from affecting your performance at work, sleep deprivation can also trigger and speed up the development of Alzheimer’s disease, and this is according to a study by Neurobiology of Aging. Lack of enough sleep stresses the body and mind while also impairing memory and learning ability.

High Lead Levels in Blood

Lead is in most cases seen as a significant threat to the health of children. But, a recent study shows that unprecedented blood lead levels in adults will increase the risk of dementia. Individuals who have a high lead level in their blood also have mild cognitive impairment and are more likely to suffer from high blood pressure, which is among the risk factors of dementia. In addition to all this, lead can also increase inflammation in your body and cause oxidative stress.

Hitting Your Head Repeatedly

Over 300,000 Americans get concussions when playing different sports every year, and this according to data from a Spine and Brain Injury Program at the University of Pittsburg. Most people know about the complications that come with head injuries. The inflammation that helps in the recovery of injured or damaged brain tissues can become chronic, and this is the link between hitting your head now and then and Alzheimer’s disease. So if you are often bumping your head, you stand a chance of damaging some vital neurons in the brain, and this can trigger dementia and Alzheimer’s disease.
