Overview

Alzheimer's is a type of dementia that affects memory, thinking and behavior. Symptoms eventually grow severe enough to interfere with daily tasks.

Differences between normal aging and Alzheimer's disease
Normal aging	Alzheimer's disease
Making a bad decision once in a while	Making poor judgments and decisions a lot of the time
Missing a monthly payment	Problems taking care of monthly bills
Forgetting which day it is and remembering it later	Losing track of the date or time of year
Sometimes forgetting which word to use	Trouble having a conversation
Losing things from time to time	Misplacing things often and being unable to find them

Symptoms

Symptoms of Alzheimer include:
1. Memory loss that disrupts daily life

One of the most common signs of Alzheimer’s disease, especially in the early stage, is forgetting recently learned information. Others include forgetting important dates or events, asking for the same questions over and over, and increasingly needing to rely on memory aids (e.g., reminder notes or electronic devices) or family members for things they used to handle on their own.

Challenges in planning or solving problems

Some people living with dementia 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.

Difficulty completing familiar tasks

People with Alzheimer's often find it hard to complete daily tasks. Sometimes they may have trouble driving to a familiar location, organizing a grocery list or remembering the rules of a favorite game.

Confusion with time or place

People living 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.

Trouble understanding visual images and spatial relationships

For some people, having vision problems is a sign of Alzheimer's. This may lead to difficulty with balance or trouble reading. They may also have problems judging distance and determining color or contrast, causing issues with driving.

New problems with words in speaking or writing

People living with Alzheimer's may have trouble following or joining a conversation. They may stop in the middle of a conversation and have no idea how to continue or they may repeat themselves. They may struggle with vocabulary, have trouble naming a familiar object or use the wrong name (e.g., calling a ''watch'' a ''hand-clock'').

Misplacing things and losing the ability to retrace steps

A person living with Alzheimer's disease may put things in unusual places. They may lose things and be unable to go back over their steps to find them again. He or she may accuse others of stealing, especially as the disease progresses.

Decreased or poor judgment

Individuals may experience changes in judgment or decision-making. For example, they may use poor judgment when dealing with money or pay less attention to grooming or keeping themselves clean.

Withdrawal from work or social activities

A person living with Alzheimer’s disease may experience changes in the ability to hold or follow a conversation. As a result, he or she may withdraw from hobbies, social activities or other engagements. They may have trouble
keeping up with a favorite team or activity.

Changes in mood and personality

Individuals living with Alzheimer’s may experience mood and personality changes. They can become confused, suspicious, depressed, fearful or anxious. They may be easily upset at home, with friends or when out of their comfort zone.
