#1 Memory Loss that Disrupts Daily Life

Memory loss is one of the most common symptoms of Alzheimer’s disease. Your loved one may forget something you just said or have trouble completing familiar tasks, like turning on the TV or getting dressed in the morning.

#2 Challenges with Planning or Problem Solving

When trying to make a decision, your loved one may have difficulty putting information together and making sense of it. For example, someone who is normally well-organized might begin needing assistance organizing a pill box, or a good cook will struggle to follow a simple recipe.


#3 Confusion with Time or Place

A person with Alzheimer’s disease may become lost in familiar surroundings or lose track of appointments. She may believe an appointment is today even though you’ve told her it isn’t until next week.


#4 Trouble Understanding Images and Spatial Relationships

People with Alzheimer’s disease may not recognize themselves in the mirror or be able to judge distances. Reading may become more difficult. Your loved one may miss his mouth with a fork full of food. Visual spatial issues can also increase the risk of falls.


#5 Misplacing Things and Losing the Ability to Retrace Steps

Your loved one may lose her house keys, and, after looking in the familiar places, the keys are found in the refrigerator or another unlikely location. If you were to misplace your keys, you'd be able to search all the places you've been that day until you found your keys. People with dementia typically can't retrace their steps to find a lost item.


#6 Decreased or Poor Judgment

One example of how a person with Alzheimer's disease may use poor judgment is with money management. For instance, your loved one may give large amounts of money to solicitors at the door or on the phone.


#7 Withdrawal from Work or Social Activities

A person with Alzheimer's may stop playing in his golf league because he is unable to calculate a score or doesn't know what club to use. He may also stop contributing to conversations because he's unable to keep up with the information or has difficulty finding the right words to express himself. These symptoms can result in increased isolation.


#8 Changes in Mood and Personality

Someone with dementia can have changes in personality. Your normally happy and trusting loved one may now become angry and suspicious of others, including you.
