One of the most common signs of Alzheimer's is forgetting recently learned information. Others include forgetting important dates or events; asking for the same information over and over; and needing to rely on memory aids (such as reminder notes) or family members for things they used to handle on their own.
Some people may experience changes in their ability to develop and follow a plan or work with numbers. They may have trouble following a familiar recipe or keeping track of monthly bills. They may have difficulty concentrating and take much longer to do things than they did before.
People with Alzheimer's may have trouble driving to a familiar location, managing a budget at work, or remembering the rules of a favorite game.
People with Alzheimer's can lose track of dates, seasons, and the passage of time. They may have trouble understanding something if it is not happening immediately. Sometimes they may forget where they are or how they got there.
Some people with Alzheimer's may have difficulty reading, judging distance, and determining color or contrast, which may cause problems with driving.
People with Alzheimer's may have trouble following or joining a conversation. They may stop talking and have no idea how to continue or they may repeat themselves. They may struggle with vocabulary, have problems finding the right word, or call things by the wrong name, such as calling a watch a hand-clock.
People with Alzheimer's may put things in unusual places. They may lose things and be unable to retrace their steps to find them again.
People with Alzheimer's may have a problem making good decisions. For example, they may give large amounts to telemarketers or may pay less attention to grooming or keeping themselves clean.
People with Alzheimer's may start to remove themselves from hobbies, social activities, work projects, or sports. They may have trouble keeping up with a favorite sports team or remembering how to complete a favorite hobby.
People with Alzheimer's can become confused, suspicious, depressed, fearful, or anxious. They may be easily upset at home, at work, with friends, or in places where they are out of their comfort zone.
