  • The purpose of this article is to explain the signs and symptoms of Alzheimer’s disease, how they vary from person to person, and how they progress over time.

Signs and Symptoms of Alzheimer’s Disease

  • The signs and symptoms of Alzheimer’s disease depend on the stage and severity of the disease, as well as the individual characteristics of the patient.
  • However, some of the common signs and symptoms of Alzheimer’s disease are:
    • Memory loss: This is the key symptom of Alzheimer’s disease, and it usually affects the recent memory first. People with Alzheimer’s may forget conversations, appointments, events, names, or places. They may also repeat themselves, ask the same questions, or misplace things.
    • Thinking and reasoning: Alzheimer’s disease affects the ability to concentrate, reason, and solve problems. People with Alzheimer’s may have trouble with numbers, such as managing finances, paying bills, or following instructions. They may also have difficulty with language, such as finding the right words, expressing thoughts, or understanding conversations.
    • Judgment and decision making: Alzheimer’s disease affects the ability to make sensible judgments and decisions in everyday situations. People with Alzheimer’s may have poor judgment, such as wearing inappropriate clothes, leaving the stove on, or driving unsafely. They may also make bad decisions, such as falling for scams, giving away money, or trusting strangers.
    • Mood and personality: Alzheimer’s disease affects the emotions and behavior of the patients. People with Alzheimer’s may experience mood swings, such as depression, anxiety, frustration, or agitation. They may also show changes in personality, such as becoming more withdrawn, apathetic, paranoid, or aggressive.
    • Daily activities: Alzheimer’s disease affects the ability to perform routine tasks and activities. People with Alzheimer’s may have trouble with personal care, such as bathing, dressing, or eating. They may also have trouble with household chores, such as cooking, cleaning, or shopping. They may also lose interest in hobbies, social activities, or work.

Stages of Alzheimer’s Disease

  • Alzheimer’s disease typically progresses in several stages, from mild to moderate to severe.
  • The stages of Alzheimer’s disease are not fixed or clear-cut, and they may overlap or vary from person to person.
  • However, some of the general features of the stages of Alzheimer’s disease are:
    • Mild Alzheimer’s disease: In this stage, the symptoms are mild and may not be noticeable to others. The person may seem healthy but have more trouble remembering things or making sense of the world. They may also have some changes in mood or personality. This stage may last for several years.
    • Moderate Alzheimer’s disease: In this stage, the symptoms are more noticeable and interfere with daily life. The person may have more confusion, memory loss, and difficulty with language and thinking. They may also have more behavioral and emotional problems, such as wandering, agitation, or hallucinations. This stage may last for several years.
    • Severe Alzheimer’s disease: In this stage, the symptoms are severe and require constant care. The person may lose the ability to communicate, recognize people, or control their movements. They may also have more physical problems, such as infections, weight loss, or seizures. This stage may last for a few months to a few years.
