It is estimated that there are approximately 44 million people worldwide living with Alzheimer's disease or a related form of dementia." Eat This, Not That!

Dacillo says, "This is one of the earliest signs of Alzheimer's, like being confused about their location or the time. This is one of the earliest signs, especially as it happens more frequently as this can significantly impact the individual's quality of life. It is important to contact a doctor when this starts to occur."

According to Dacillo, "This is one of the biggest signs for Alzheimer's as typically, people are able to carry a flow of conversation with another individual. If the person constantly repeats the same phrase a few times, especially in a short period of time, it is a huge indicator that the person may have Alzheimer's."


Sudden Personality Changes

"While people can change their personality slowly over time, it is alarming if the individual suddenly becomes anxious, tense, or suspicious," says Dacillo. "Sudden changes in their personality indicates that there might be a change in their brain chemistry."

Dacillo explains, "Alzheimer's typically starts to affect people over the age of 65. Since Alzheimer's is typically a combination of genetics, environmental, and lifestyle impacts on the brain, people above the age of 65 are more susceptible to developing Alzheimer's. One in six people over the age of 80 have dementia, in which most have Alzheimer's. Women are also more likely to be affected than men statistically."

"While people can develop Alzheimer's due to family history, it can be prevented with certain lifestyle changes," Dacillo states. "It is important to keep the body healthy by not smoking, maintaining a healthy weight, exercising regularly, eating healthy, managing any health problems etc. It is also important to ensure that the brain is constantly stimulated by learning new hobbies, reading, and solving puzzles to exercise it. Maintaining a good social life by doing group activities, games night, attending church or support groups can help with keeping the social aspect of life."

Difference Between Normal Aging and Alzheimer's

Dacillo explains, "Since one of the most common signs of Alzheimer's is memory loss, which could also be a sign of normal aging, the difference with aging is that if someone forgets to do a task, they would typically remember to do it later or that they remembered that they forgot to do something. With Alzheimer's, the individuals are unable to remember what they forgot to do, and they also may forget how to do the task. The memory loss in those with Alzheimer's becomes more and more debilitating, whereas people who usually age will continue to complete their activities over time, possibly with assistance."  And to protect your life and the lives of others, don't visit any of these 35 Places You're Most Likely to Catch COVID.
