Medicine cannot stop dementia with Lewy bodies getting worse, but for some people it can help reduce some of the symptoms.

Acetylcholinesterase inhibitors

Acetylcholinesterase (AChE) inhibitors, such as donepezil (Aricept), rivastigmine (Exelon) and galantamine (Reminyl), may help improve hallucinations, confusion and sleepiness in some people.

These work by increasing levels of a chemical called acetylcholine in the brain, which improves the ability of the brain cells to send signals to each other.

Common side effects include feeling and being sick, diarrhoea, headaches, tiredness and muscle cramps.


This medicine is not an AChE inhibitor. It works by blocking the effects of a large amount of a chemical in the brain called glutamate.

Memantine is used for moderate or severe dementia with Lewy bodies. It's suitable for those who cannot take AChE inhibitors.

Side effects can include headaches, dizziness and constipation, but these are usually only temporary.

For more information about the possible side effects of your specific medicine, read the patient information leaflet that comes with it and speak to a doctor.
