Signs and Symptoms of Alzheimer's Disease

Is it normal to lose your keys, or is it a symptom of Alzheimer's? Does a person exhibit different symptoms at different stages of the disease? While each person with Alzheimer's is unique, there are some trademark symptoms that occur as the disease progresses.
The Truth Behind Senior Moments
If you've ever experienced senior moments -- a nonmedical term for mental glitches -- you're not alone. Over time, the brain often experiences some normal age-related memory loss, which can lead to a variety of senior moments. Learn what causes senior moments, how they differ from Alzheimer's disease and how to manage senior moments, so that they become only occasional annoyances.
Symptoms of Alzheimer's
Although each person with Alzheimer’s is different, most individuals advance through a series of stages characterized by progressively more serious symptoms. Seven stages developed by researchers and physicians describe how a person’s functioning changes over time, from a normally functioning adult to someone with severe, advanced Alzheimer’s disease.
What Is Mild Cognitive Impairment?
Years ago, memory loss was considered to simply be an inevitable part of aging. Today, however, we know that memory loss once considered normal now may be an early sign of disease, or mild cognitive impairment (MCI). Learn more about mild cognitive impairment and memory loss in aging adults.
Early Indicators of Alzheimer's Disease
Before a diagnosis of Alzheimer's disease, people often notice early indicators -- either about themselves or about a relative -- that signal possible Alzheimer's. Be aware of the 10 classic warning signs first identified by the Alzheimer's Association.
Early-Onset Alzheimer's: Signs, Symptoms, and Diagnosis
About 5% of those with Alzheimer's disease have early-onset Alzheimer's, which affects people younger than age 65. Learn about the signs, symptoms, and diagnosis of early-onset Alzheimer's disease.
How Does Alzheimer's Disease Affect Communication?
People with Alzheimer’s lose particular communication abilities during the early, middle, and late stages of the disease. Learn what to expect and what kinds of communication challenges can occur during each stage of Alzheimer's.
Alzheimer's Disease and Sexuality
Alzheimer's disease can cause inappropriate behavior with sexual overtones (undressing in public) as well as take a toll on physical intimacy, especially when the afflicted partner can no longer give meaningful consent. Learn what sexuality changes to expect in relation to Alzheimer's disease and how to cope with them.
Alzheimer's Disease and Anxiety
Alzheimer's disease causes many problems, including anxiety. This feeling of uneasiness, fear, and apprehension can increase distress for both individuals with Alzheimer's and their caregivers, but a number of pharmaceutical and behavioral strategies can help.
Sleep Disturbance in Alzheimer's Disease
It is estimated that up to 70% of people with Alzheimer's disease will experience disruption of nighttime sleep. Practitioners recommend a variety of coping mechanisms for sleep disorders, ranging from medication to changes in daily routines. Learn how to manage sleep disturbance in Alzheimer's disease.
Symptoms of Late-Stage Alzheimer's Disease
In late-stage Alzheimer's, the disease finally begins to considerably affect parts of the brain that control bodily systems such as motor coordination, bowel and bladder function, and even breathing. Learn about the symptoms of late-stage Alzheimer's disease.
Forgetfulness: It's Not Always What You Think
While there are many reasons we become forgetful at times, we often fear that a forgetful episode signals Alzheimer's. The National Institute on Aging reminds us that forgetfulness could be due to several other factors under our control.
