Stages of Alzheimer's

Researchers an physicians use 2 major model systems to determine the Alzheimer's stages in order to help patients and their families understand how this disease will change over time.

Alzheimer's stage Model with 3 stages:

  1. Early / Mild Stage (Duration 2 to 4 years) : Patients may have memory loss for recent conversations and events.  They will need reminders for finding their belongings and other daily activities.  Their problem solving, decision making and judgment skill will slow down.
  2. Middle / Moderate Stage (Duration 2 to 10 years):  Patients will have difficulties in decision making and judgment.  They may start forgetting some important personal information, such as home address and phone number.  Patients may also have significant change in their personality.
  3. Late / Severe Stage (Duration 1 to 3+ years): Patients will start losing their physical abilities, such as the ability to dress, walk, and communicate.  They will not  be able to take care of themselves and extensive care should be provided.

Alzheimer's stage Model with 7 stages (By Christine Kennard):

  1. Alzheimer’s Stage 1: No Cognitive Decline  -  No memory problem and it is hard to detect any noticeable symptoms in this stage
  2. Alzheimer’s Stage 2: Very mild cognitive decline  -  Very slight lapses in memory loss and cognitive decline and it is still hard to detect in this early stage.
  3. Alzheimer’s Stage 3: Mild cognitive decline  -  Patient start having memory loss for recent events and conversations.  They will also have slight difficulties in making decisions and judgment.  Friends and family members may become aware of these symptoms.
  4. Alzheimer’s Stage 4: Moderate cognitive decline  -  Patient start having problem in performing complex daily tasks, such as managing personal finances and travel to unfamiliar locations.  Patients should immediately seek for  help from physicians.
  5. Alzheimer’s Stage 5: Moderately severe cognitive decline  -  Patients will start losing some of their physical abilities and will need assistance  to perform daily tasks.  They may start forgetting some important personal information, such as home address and phone number.
  6. Alzheimer’s Stage 6: Severe cognitive decline  -  Patients will start losing most of their physical abilities, such as bathing and talking.  They may even forget their names and names of their family members.  Patients may also have significant change in their personality.
  7. Alzheimer’s Stage 7: Very severe cognitive decline  -  They will not able to take care of themselves and extensive care should be provided at this stage.  This is the last stage of the progression, patient's will start suffering with infections and pneumonia as organs begin to shutdown down.
