Lewy Body Dementia Documentary
Dementia with Lewy bodies (DLB) is a type of dementia accompanied by changes in behavior, cognition and movement. Memory loss is not always present early. Dementia steadily worsens over time and the condition is diagnosed when cognitive decline interferes with normal daily functioning. A core feature is REM sleep behavior disorder (RBD), in which individuals lose normal muscle paralysis during REM sleep, and act out their dreams. RBD may appear years or decades before other symptoms. Other frequent symptoms include visual hallucinations; marked fluctuations in attention or alertness; and slowness of movement, trouble walking, or rigidity. The autonomic nervous system is usually affected, resulting in changes in blood pressure, heart and gastrointestinal function, with constipation as a common symptom. Mood changes such as depression and apathy are common.
