Understanding a Lewy Body Dementia Diagnosis

lewy-body-dementia

Lewy Body Dementia (LBD) affects 1.4 million people in the United States and is the second leading cause of dementia, according to the Lewy Body Dementia Association. LBD is a combination of two distinct diagnoses, Parkinson’s disease dementia and dementia with Lewy bodies.

Lewy bodies are clumps of abnormal proteins in the outer layer of the brain, the cerebral cortex and are associated with both forms of dementia. When dementia develops after the established motor disorder, it is called Parkinson’s disease with dementia (PDD). When dementia occurs at the same time as the motor disorder, it is called dementia with Lewy bodies (DLB). They are both on the continuum of the same disease. These two conditions can cause the same underlying biological changes in the brain. In the later stages, the two diagnoses exhibit similar behavioral, cognitive, physical, and sleep symptoms. Sufferers also frequently experience hallucinations and bouts of ongoing depression.

Getting the Right Diagnosis

Despite being widespread, LBD is frequently underdiagnosed and misdiagnosed by health care professionals. It can resemble other causes of dementia such as Alzheimer’s disease. James E. Galvin, MD at Florida Atlantic University has developed a way to assess and diagnose LBD. The system is known as the Lewy Body Composite Risk Score (LBCRS).

The LBCRS system of diagnosis is based on a rating scale. The assessment is one page long and features six questions that quickly outline whether the patient suffers from six non-motor symptoms that are distinct to LBD, but not other forms of dementia. The physician can quickly determine if the person suffers from rest tremors, rigidity, bradykinesia, or postural instability by asking a few questions.

Getting the Help You Need

A clear diagnosis of LBD is imperative to help prevent patients from being misdiagnosed and, therefore, misprescribed. In fact, taking the wrong medication could possibly have serious adverse consequences and will not help to treat LBD.

A definitive and prompt diagnosis of LBD gives physicians the chance to quickly begin medical therapies that may help or improve the quality of life for the LBD sufferer. Usually, a combination of the Lewy Body Composite Risk Score System, PET scans, CSF biomarkers, high-density EEG, and MRI tests are used to arrive at a clear diagnosis of LBD.

Facing a Lewy Body Dementia diagnosis can be frightening for both the patient and their loved ones. If you need extra help caring for a loved one who suffers from LBD, our in-home health care services, whether part time or full, can offer you additional support.

Genetics + Environment ≠ Inevitable Health Profile

A new study gives insight into the role of exercise on overall health measures while controlling for genetics and childhood influences. A study out of Finland examined ten sets of identical twins for the effects of exercise on health and brain development while controlling for genetics and childhood influences. One twin was active physically and the other was sedentary.

AA052490Ten sets of identical twins from Finland, who grew up together, obviously sharing the same DNA, were examined. While their pasts were similar, their future exercise habits differed. While past studies of twins with respect to divergent exercise habits focused on their effects on aging, this study focused on factors that measured overall health: endurance capacity, body composition and insulin sensitivity. The sedentary twins exhibited lower endurance capacity, higher body fat percentages and signs of metabolic problems with respect to insulin resistance. The active twin had more grey matter than his sedentary counterpart especially in the areas having to do with motor control and coordination. Interestingly, the twins had similar diets. This led the research team to conclude “that the results strongly imply that the differences in the twins’ exercise habits caused the differences in their bodies.”

On the bright side, genetics and environment don’t equal inevitability. We can make significant changes with respect to exercise regimens that can dramatically impact our overall health and that of our brains.
