Overview
Although each patient experiences Alzheimer's in a unique way, there are many common symptoms.[1] The earliest observable symptoms are often mistaken for normal effects of aging or manifestations of stress.[2]
Symptoms
The most commonly recognized symptom of early Alzheimer's disease is memory loss, which usually involves the forgetting of recently learned facts. As the disease advances, symptoms include confusion, irritability, aggression, mood swings, language breakdown, long-term memory loss, and the general withdrawal of the sufferer as their senses decline.[2][3] Gradually, bodily functions are lost, ultimately leading to death.[4]
Dementia symptoms include difficulty with many areas of mental function, including:
- Language
- Memory
- Perception
- Emotional behavior or personality
- Cognitive skills (such as calculation, abstract thinking, or judgment)
Dementia usually first manifests as forgetfulness.
Mild cognitive impairment is the stage between normal forgetfulness due to aging and the development of AD. People with MCI have mild problems with thinking and memory that do not interfere with everyday activities. They are often aware of the forgetfulness. Not everyone with MCI develops AD.
Symptoms of mild cognitive impairment include:
- Forgetting recent events or conversations
- Difficulty performing more than one task at a time
- Difficulty solving problems
- Taking longer to perform more difficult activities
The early symptoms of AD can include:
- Language problems, such as trouble finding the name of familiar objects
- Misplacing items
- Getting lost on familiar routes
- Personality changes and loss of social skills
- Losing interest in things previously enjoyed; flat mood
- Difficulty performing tasks that take some thought, but used to come easily, such as balancing a checkbook, playing complex games (such as bridge), and learning new information or routines
As the AD becomes worse, symptoms are more obvious and interfere with your ability to take care of yourself. Symptoms can include:
- Forgetting details about current events
- Forgetting events in your own life history, losing awareness of who you are
- Change in sleep patterns, often waking up at night
- Difficulty reading or writing
- Poor judgment and loss of ability to recognize danger
- Using the wrong word, mispronouncing words, speaking in confusing sentences
- Withdrawing from social contact
- Having hallucinations, arguments, striking out, and violent behavior
- Having delusions, depression, agitation
- Difficulty doing basic tasks, such as preparing meals, choosing proper clothing, and driving
People with severe AD can no longer:
- Understand language
- Recognize family members
- Perform basic activities of daily living, such as eating, dressing, and bathing
Other symptoms that may occur with AD:
