Lewy Body Dementia (LBD), is estimated to effect approximately 1.4 million Americans. LBD includes patients from both dementia with Lewy bodies and Parkinson’s disease dementia diagnoses. People with LBD often experience the same symptoms as Alzheimer’s patients, in addition to sleep disturbances, visual hallucinations, muscle rigidity or other Parkinsonism physical and cognitive impairments.
Lewy body dementia (LBD) is caused by abnormal protein deposits that disrupt the brain's normal functioning. The proteins found in the brain stem deplete dopamine levels, causing Parkinson’s-like symptoms. LBD symptoms include problems with memory, perception, thinking and behavior. Symptoms of LBD vary from person to person, and may fluctuate at any moment, or any day. LBD greatly impacts a person’s daily life and ability to function independently. There is no cure for LBD, but treatment for symptoms is available to improve a person’s quality of life. Common warning signs of LBD can include any combination of the following symptoms: memory loss, trouble planning or problem solving, difficulty completing normal tasks, confusion, frequent falls, muscle rigidity, disorientation, difficulty understanding spatial relationships, trouble with words or speaking, poor judgment, changes in mood or personality, hallucinations, sleep disturbances or tremors.
