Happy Wednesday lovely readers & friends,
Just been feeling a little uninspired as of lately with writing posts here, so please forgive me for my absence.
Today’s post is about something that caught my attention and I felt the need to share it.
It is about a condition known as Lewy Body Dementia, which I wanted to raise awareness of after reading a post by Robin Williams’s widow.
This condition is apparently what led Robin Williams to take his own life, after suffering severely in the last months before his death.
So what is Lewy Body Dementia?
LBD is not a rare disease. It affects an estimated 1.4 million individuals and their families in the United States. Because LBD symptoms can closely resemble other more commonly known diseases like Alzheimer’s and Parkinson’s, it is currently widely underdiagnosed. Many doctors or other medical professionals still are not familiar with LBD.
LBD is an umbrella term for two related diagnoses. LBD refers to both Parkinson’s disease dementia and dementia with Lewy bodies. The earliest symptoms of these two diseases differ, but reflect the same underlying biological changes in the brain. Over time, people with both diagnoses will develop very similar cognitive, physical, sleep, and behavioral symptoms.
What are the symptoms of this disease?
LBD is a an umbrella term for two related clinical diagnoses, dementia with Lewy bodies and Parkinson’s disease dementia.
The latest clinical diagnostic criteria for dementia with Lewy bodies (DLB) categorizes symptoms into three types, listed below. A diagnosis of Parkinsons’ disease dementia (PDD) requires a well established diagnosis of Parkinson’s disease that later progresses into dementia, along with very similar features to DLB. A rather arbirary time cutoff was established to differentiate between DLB and PDD. People whose dementia occurs before or within 1 year of Parkinson’s symptoms are diagnosed with DLB. People who have an existing diagnosis of Parkinson’s for more than a year and later develop dementia are diagnosed with PDD.
- Progressive dementia – deficits in attention and executive function are typical. Prominent memory impairment may not be evident in the early stages.
- Fluctuating cognition with pronounced variations in attention and alertness.
- Recurrent complex visual hallucinations, typically well formed and detailed.
- Spontaneous features of parkinsonism.
- REM sleep behavior disorder (RBD), which can appear years before the onset of dementia and parkinsonism.
- Severe sensitivity to neuroleptics occurs in up to 50% of LBD patients who take them.
- Low dopamine transporter uptake in the brain’s basal ganglia as seen on SPECT and PET imaging scans.
- Repeated falls and syncope (fainting).
- Transient, unexplained loss of consciousness.
- Autonomic dysfunction.
- Hallucinations of other senses, like touch or hearing.
- Visuospatial abnormalities.
- Other psychiatric disturbances.
A clinical diagnosis of LBD can be probable or possible based on different symptom combinations.
A probable LBD diagnosis requires either:
- Dementia plus two or more core features, or
- Dementia plus one core feature and one or more suggestive features.
A possible LBD diagnosis requires:
- Dementia plus one core feature, or
- Dementia plus one or more suggestive features.
