Because different parts of the brain control different functions, the same lesion in one part of the brain will cause one set of symptoms and in another part of the brain will cause a different set of symptoms. Scenario 1A patient blog develops a series of neurologic symptoms, is evaluated by a neurologist and is told that she has Parkinson’s disease (PD). She then visits another neurologist for a second opinion and is told she has Lewy Body Dementia (LBD).

For example, both are caused by protein deposits on the brain. These protein deposits consist of alpha-synuclein, which are called Lewy bodies. Both are chronic and progressive, meaning they tend to get worse over time. Both Parkinson’s disease and LBD affect some 1 million people in the United States, respectively.

Fluctuating cognitive function is a relatively specific feature of dementia with Lewy bodies. Periods of being alert, coherent, and oriented may alternate with periods of being confused and unresponsive to questions, usually over a period of days to weeks but sometimes learn here during the same interview. Dementia is chronic, global, usually irreversible deterioration of cognition. People with Lewy body dementia might experience Parkinson’s disease symptoms. These symptoms may include rigid muscles, slow movement, trouble walking and tremors.

Research suggests that Lewy bodies play a role in several conditions that cause dementia. Lewy body dementia results from a buildup of Lewy bodies, which are abnormal deposits of a protein called alpha-synuclein. These deposits eventually damage brain cells, leading to dementia. Most of the available anti-psychotics click this link now are always avoided in both the DLB and PDD population because they block dopamine receptors and can cause significant motor dysfunction. However, two anti-psychotic medications, quetiapine and clozapine, are sometimes used in PDD and DLB patients as they have less of an ability to worsen motor symptoms.

The condition causes memory loss, behavioral changes, and progressively worsening movement symptoms that are the same as those that occur in Parkinson’s disease. Parkinson’s disease is a neurological condition that develops slowly and primarily affects nerve cells in an area of the brain called the substantia nigra. The nerve cells in this region produce dopamine, which is a neurotransmitter that regulates various bodily processes, including movement.

Lewy bodies are abnormal accumulations of protein that occur in nerve cells in the brain. They were first described in 1912 in the brains of people with PD. Parkinson disease dementia may affect multiple cognitive domains including attention, memory, and visuospatial, constructional, and executive functions. Executive dysfunction typically occurs earlier and is more common in Parkinson disease dementia than in Alzheimer disease.

LBD and PD are different but related neurological diseases that can cause issues with movement, thinking, and memory. If you are having symptoms that concern you, make an appointment with your doctor. DLB gained more visibility in the press when Robin Williams, the beloved comedian, died in 2014 with this condition. At APDA, we strive to further our understanding of Lewy body disorders through our research funding.
