Beyond the Fading Memories: An understanding of LBD

 Understanding Lewy Body Dementia (LBD)

Robin Williams suffered from Lewy Body Dementia

Lewy Body Dementia (LBD) is one of the most common neurocognitive disorders in older adults. Unfortunately, it is often misunderstood or misdiagnosed. Next to Alzheimer's disease, it is the second most common cause of dementia and is frequently mistaken for Parkinson's disease due to overlapping symptoms (Galvin & Howard, 2020).



What Causes Lewy Body Dementia?

LBD is caused by Lewy Bodies, abnormal deposits of a protein called alpha-synuclein in the brain that disrupt communication between brain cells which eventually leads to the death of the cells. This affects both thinking and memory (cognitive function) and movement (Armstrong, 2021). Over time, the damage becomes progressively worse leading to functional decline.

This short video explains how Lewy bodies form in the brain and why the disease is often misdiagnosed. It highlights how protein buildup interferes with brain function and leads to symptoms like hallucinations, movement problems, and memory loss.



Common Signs and Symptoms

Symptoms of LBD can vary, but the most common include:
  • Fluctuating attention and alertness
  • Memory loss and confusion
  • Visual hallucinations (seen in up to 80% of patients)
  • Sleep disturbances
  • Parkinson-like movement problems (tremors, stiffness, slow movement)
  • Mood changes such as depression, anxiety, or apathy

A key distinguishing feature of LBD is that cognitive symptoms typically appear before movement problems, which helps differentiate it from Parkinson’s disease (Armstrong, 2021).

Estelle Getty, made famous by playing a part in the TV Series "The Golden Girls" had Lewy Body Dementia


Treatment Options

There is no cure for LBD, but treatment focuses on managing symptoms and improving quality of life.

Pharmacological Treatments

  • Cholinesterase inhibitors (e.g., donepezil) to support cognitive function
  • Careful use of antipsychotic medications, as patients may be highly sensitive
  • Medications to manage sleep disturbances and motor symptoms

Non-Pharmacological Treatments

  • Structured daily routines
  • Physical therapy and regular exercise
  • Cognitive stimulation (puzzles, music, memory activities)
  • Environmental modifications to reduce confusion and stress

Treatment plans should always be individualized due to the complexity of the disease (Galvin & Howard, 2020).



Promoting Health, Well-Being, and Quality of Life

The most important aspect of managing LBD is maintaining the highest possible quality of life.

  • Maintain a Consistent Routine
  • Create a Safe Living Environment
  • Encourage Physical Activity
  • Support Cognitive Function
  • Manage Stress and Emotional Health
  • Provide Caregiver Support

Caregivers should:

  • Use calm, simple communication
  • Avoid arguing about hallucinations
  • Take breaks and seek support

Strong caregiver support significantly improves patient outcomes and quality of life (Galvin & Howard, 2020).

Predictable daily schedules help reduce confusion and anxiety and improve overall functioning. It is necessary to make the patient's home safe by:

  • Remove tripping hazards
  • Ensure adequate lighting
  • Install safety equipment such as grab bars
These changes reduce fall risk and help prevent injury. Regular physical activity improves mobility, reduces stiffness, and supports mental health and by engaging in meaningful activities such as music therapy, reminiscing, or simple games can help maintain cognitive abilities. Stress, however, can worsen symptoms. Techniques such as mindfulness, relaxation exercises, and social interaction can improve emotional well-being (National Institute on Aging, 2023).


Casey Kasem was most famous for his weekly music countdowns and playing the voice of Shaggy in the "Scooby Doo" cartoons suffered from Lewy Body Dementia. 

Local Resources for Support (Orlando, Florida Area)


Lewy Body Dementia is a complex and progressive condition affecting both cognitive and physical health. While there is no cure, early diagnosis, proper treatment, and strong support systems can significantly improve quality of life. Focusing on routine, safety, emotional support, and community resources helps both patients and caregivers better manage this disease.
