Lewy Body Dementia: Is It PDD or DLB?

LEWY BODY DEMENTIA is the second one maximum common dementia in addition to dementia’s maximum misdiagnosed kind. Yet diagnosing it efficaciously is important for correct remedy. Learn about the two sorts of LBD, in addition to forms of dementia for which docs mistake it.Lewy body dementia (LBD) affects 1.Three million Americans. It is the second one maximum not unusual motive of progressive dementia. However, it is the maximum misdiagnosed form of dementia.

Misdiagnosing Lewy Body Dementia

Parkinson’s Disease: LBD may be misdiagnosed as Parkinson’s sickness as it’s related to “parkinsonism” or motion signs that resemble those of Parkinson’s sickness.
Alzheimer’s Disease: LBD is regularly misdiagnosed as Alzheimer’s. Many of the signs ar similar. Furthermore, Alzheimer’s is the most commonplace kind of dementia, affecting extra than 1/2 of elders with dementia. Therefore, Alzheimer’s is typically the primary prognosis that comes to thoughts when doctors see symptoms of dementia.

LBD is not well recognized by physicians, especially primary care physicians and other general practitioners.

Recognizing LBD at its earliest stage is critical not only because an early diagnosis may protect people with Lewy body dementia from treatments that can worsen their symptoms or cause severe side effects, but also because it ensures individuals receive comprehensive symptom management that could improve their quality of life.

2 Types of LBD

Lewy frame dementia refers to 2 related diagnoses:
Parkinson’s disorder dementia (PDD)
Dementia with Lewy bodies (DLB).
Both PDD and DLB are taken into consideration Lewy frame dementias. The distinction is inside the presentation of signs based totally at the “one-12 months rule.” With DLB, cognitive (wondering) symptoms that intrude with each day living appear before or within a yr of motion troubles resembling Parkinson’s disorder. With PDD, cognitive signs and symptoms do not usually increase till extra than a yr after movement issues start.

Early Diagnosis

“An early and accurate diagnosis may be lifesaving,” says Howard I. Hurtig, M.D., Chair, Department of Neurology, Pennsylvania Hospital, and Elliott Professor of Neurology. While the symptoms of LBD may be similar to Alzheimer’s and Parkinson’s disease, the treatment strategy is more challenging because fewer medications can be used safely. Hurtig warns, “The avoidance of medications that can worsen the symptoms of LBD cannot be overemphasized. Every patient with LBD and their caregiver(s) should memorize the list of acceptable and forbidden drugs.

Why is Diagnosis So Complicated?

Lewy body dementia (LBD) is characterized by an abnormal build up of Lewy bodies (alpha-synuclein protein deposits) in the areas of the brain that regulate behavior, memory, movement and personality. The most prominent symptoms of Parkinson’s disease affect motor abilities. Alzheimer’s disease primarily affects areas of the brain involving learning and memory. What complicates diagnosis is that some people may have changes in the brain from more than one memory disorder. Most often a specialist like a neurologist or geriatric psychiatrist will distinguish symptoms to achieve an accurate diagnosis, sometimes with the help of a neuropsychologist, who plays an important role in understanding cognitive problems.
