Symptoms of Middle (Intermediate) Stage of Alzheimer's Disease

  • Starting to have trouble carrying out everyday activities such as bathing, dressing, and grooming without help
  • Major gaps in memory begin to be evident, with individuals often unable to recall their address, the year, the season, and recent events.
  • Individuals often incorrectly remember their personal history.
  • Inability to think clearly and solve problems
  • Inability to make judgments such as dressing for the weather
  • Difficulty with understanding or learning new information
  • Speaking, reading, and writing are difficult, but individuals can usually read and understand short phrases, especially common ones.
  • Individuals can be disoriented or confused even in familiar surroundings, occasionally forgetting names of people close to them.
  • Beginning to experience significant behavioral symptoms such as anxiety, suspiciousness, hallucinations, or delusions
  • They can still remember things that happened long ago and recognize people from early in their life.
  • They still recognize their own face.
  • They can interpret simple sensory experiences (sound, taste, smells, sights, and touch).
  • Walking and mobility are usually not difficult.
  • They can usually still eat and use the toilet without assistance.
  • Individuals can make decisions requiring a simple yes/no and either/or judgment

Symptoms of Late Stage of Alzheimer's Disease

  • Complete loss of short- and long-term memory, potentially even the inability to recognize even close relatives and friends.
  • Complete dependence on others for everyday activities including eating and using the toilet.
  • Urinary or stool incontinence.
  • Severe disorientation- including wandering and getting lost.
  • Heightened behavior or personality changes such as hostility or aggressiveness, may be apparent.
  • Individuals lose their mobility and may be unable to walk or move or even sit without help.
  • Impaired ability to communicate.
  • Other movements, such as swallowing are impaired, which increases the risk of malnutrition, choking, and aspiration.
  • Interpreting and using basic body language is still possible.
  • Individuals can usually still understand and experience sensory information.
