LBD is a complex disease that can present with a range of physical, cognitive, and behavioral symptoms. Many caregivers find that behavioral symptoms (e.g., hallucinations, delusions, aggression, agitation, apathy, depression and anxiety) are the most distressing and difficult-to-treat aspects of LBD. This paper discusses some of the causes of behavioral symptoms, as well as strategies and treatments to reduce their frequency and severity.
Understanding Behavioral Symptoms
Some behavioral symptoms of LBD are subtle and may go overlooked for some period of time. Other symptoms are easily recognizable the first time they occur. Here are some examples of the kinds of behavioral symptoms seen in LBD:
Perception of an object or event when the object or event is not really present. Typically visual in LBD, but rarely, hallucinations can be auditory (hearing), olfactory (smell), gustatory (taste), or tactile (touch) as well.
(Also includes illusions – a misperception of an object or event that is real.)
Seeing children or small animals
Seeing bugs crawling on the floor or walls
Smelling bad odors that others cannot smell
Hearing people talking when no one is there
Strongly held false belief or opinion, not based on evidence or data.
Also includes paranoia, an extreme, irrational distrust of others.
