Symptoms of Lewy body dementia include a progressive cognitive decline that interferes with daily activities, unpredictable changes in attention and alertness, visual hallucinations, and motor symptoms similar to those of Parkinson’s disease such as slow movements, rigidity, difficulty walking, tremors or shaking, balance issues, and a loss of coordination. The disease affects thinking, behavior, movement, and mood. People with LBD may also experience depression, anxiety, and sleep disorders.
Early signs of LBD may start mild and progress to become more severe. Due to the severity and progression of symptoms, LBD ultimately leads to a loss of independence, requiring individuals with the disease to receive increasing levels of personal assistance and caregiving over time.
