Each and every year, thousands of American seniors are told they have Parkinson’s disease, but they do not. For many of these patients, the correct diagnosis is a very similar but not as well-known disease: dementia with Lewy bodies (DLB).
Dementia with Lewy bodies affects around 1.3 million Americans, according to the Lewy Body Dementia Association (LBDA). That estimate could possibly be too low since some individuals who've been inaccurately diagnosed with Parkinson’s still have not been given an accurate diagnosis.
So, what is dementia with Lewy bodies and how is it different from Parkinson’s? It can be difficult to differentiate, because the signs and symptoms for the two diagnoses can be very similar, particularly as they progress, as they reflect similar underlying modifications in the brain.
Here are the symptoms you should know about, according to the LBDA:
- Intensifying dementia – Increasing confusion and reduced attention and executive function are common. Memory impairment may not be obvious in the early stages.
- Frequent visual hallucinations – These are commonly intricate and elaborate.
- Hallucinations of other senses – Touch or hearing are probably the most frequent.
- REM sleep behavior disorder – This might appear decades ahead of the onset of dementia and Parkinson’s.
- Recurring falls and fainting – Includes undetermined loss in consciousness.
- Other psychiatric disruptions – These differ from patient to patient.
Is a correct diagnosis actually essential? Diagnosing DLB quickly and properly could possibly mean the difference between life and death, according to Howard I. Hurtig, M.D., Chair, Department of Neurology, Pennsylvania Hospital and Elliott Professor of Neurology. Improperly treating DLB will not only cause serious adverse side effects, but can even worsen symptoms and prevent accurate symptom management.
Some of the confusion among physicians comes from the fact that both Parkinson’s disease and DLB fall into the same umbrella of Lewy body dementias.
An important distinction is in the “one-year rule” related to cognitive symptoms. Patients with Parkinson’s disease in most cases do not present cognitive issues until at least one year after movement symptoms start. DLB is the exact opposite, with cognitive symptoms developing first for at least one year.
