These Alzheimer's disease medications, such as rivastigmine (Exelon), donepezil (Aricept) and galantamine (Razadyne), work by increasing the levels of chemical messengers in the brain (neurotransmitters) believed to be important for memory, thought and judgment.

What are the end stages of Lewy body dementia?

In advanced LBD, communication often becomes quite difficult. Voice changes, poor attention, confusion, and word-finding problems are common; impaired communication can also lead to anxiety or agitation.

What's the difference between dementia and Louie body dementia?

How do you get rid of Lewy bodies?

Is there a cure? There is no cure for Lewy body dementia (LBD). Medications and nonmedical therapies, like physical, occupational and speech therapies, manage symptoms as much as possible. Medications called cholinesterase inhibitors (Aricept®, Exelon®, Razadyne®) help manage the cognitive symptoms of LBD.

What medications should be avoided with Lewy body dementia?

If possible, avoid medications with anticholinergic properties, which can worsen cognition, or dopamine agonists, which can cause hallucinations. First-generation antipsychotic medications, such as haloperidol (Haldol), should not be used to treat Lewy body dementia.
