Each case of dementia with Lewy bodies (DLB) is as individual as the person living with it. Different people will show different combinations of symptoms. At present a diagnosis of DLB can only be confirmed by autopsy but a careful clinical evaluation of the patient and his or her symptoms can, in many cases, form the basis for making a reasonably confident lifetime diagnosis.
The symptoms of DLB can be grouped as central, core, suggestive or supportive .
The central symptom of dementia with Lewy bodies is dementia, or progressive mental decline serious enough to interfere with normal daily activities. Significant memory loss may not develop until later. There may also be problems with attention, problem solving and spatial awareness. This can easily be mistaken for Alzheimer’s disease or for Parkinson’s disease (PD) with dementia.
