7 Stages Of Lewy Body Dementia

7 Stages Of Lewy Body Dementia

Lewy Body Dementia, one of the most common forms of dementia, is often confused for both Alzheimer’s and schizophrenia. LBD can either develop over time or generate in combination with numerous other brain disorders, according to nia.nih.gov. Typically, LBD symptoms will not be noticed for a long time. The average lifespan of someone diagnosed with LBD is 5-8 years, yet recent studies have shown 2-20 years is also a possible range.

Here are the 7 stages associated with this progressive disease:

Stage 1: Normal Behavior

The first stage of LBD will yield little to no signs at all of a present disease. No symptoms means there will be zero impact on the individual’s current lifestyle at this point.


  • No symptoms are associated with stage one.

Stage 2: Mild Changes

It is very possible, if not likely, that you will not notice any symptoms during stage two of LBD. Memory issues during this stage are commonly ignored or brushed off as a normal part of the aging process.


  • Mild difficulty finding words.
  • Normal functioning in and out of the home.
  • The ability to overcome any memory issues remains intact.

Stage 3: More Mild Changes

Stage three tends to be the time where some slight mood changes may become noticeable. You should be able to see your loved one’s thinking and memory issues at this point.


  • Problems at the workplace.
  • Forgetfulness.
  • Difficulty paying attention.
  • Trouble finding the right words/names.
  • Issues managing money.

Stage 4: Mild Dementia

Your loved one will experience mild dementia symptoms. Important past events, friends and family should still be recognized by the individual, though.


  • Limited knowledge of past events.
  • Problems with daily tasks.
  • Driving mistakes.
  • Issues with problem solving.
  • More problems with finances.
  • Forgetting names or items.
  • Misplacing important things like keys/wallet.

Stage 5: Moderate To Severe Mental Decline

While the individual may still be able to recognize family and friends, they may begin showing increased signs of difficulty remembering past events. Your loved one may require help performing routine daily tasks during stage five.


  • Gaps in memory.
  • Personality changes.
  • Mood swings.
  • Needing assistance with daily tasks.
  • Bladder problems.
  • Repeating thoughts/questions.

Stage 6: Severe Decline

Memories will fade quickly during this nearly final stage of LBD. 24-hour at-home care is suggested for your loved one at this time.


  • Unusual eating habits.
  • Strong mood swings and personality changes.
  • Getting lost and confused.
  • Continuing bladder issues.
  • Delusions.
  • Lack of overall awareness.

Stage 7: Severe Dementia

Your loved one will no longer recognize friends and family. 24-hour care is essential during LBD’s final stage.


  • Loss of muscle control.
  • Loss of bladder and bowel control.
  • Constantly disoriented.
  • No ability to eat, swallow or speak.
