Lewy body dementia vs. dementia
LBD is a particular kind of dementia that differs from Alzheimer’s.
Alzheimer’s, for one, is primarily characterised by the buildup of beta-amyloid plaques and tau tangles instead of Lewy our bodies.
“LBD has many core clinical features that distinguish this form of dementia from Alzheimer’s disease,” Dr. Jonathan Fellows from the Michigan Institute for Neurological Disorders beforehand told The Post.
“Patients can experience fluctuations in their cognition, alertness and attention, which can vary from day to day or even from hour to hour.”

“Symptoms similar to those of patients with Parkinson’s disease can sometimes be managed with levodopa therapy, such as Sinemet.”
Atypical antipsychotic medication is used to deal with symptoms like hallucinations, delusions and agitation. However, Fellows emphasised that conventional antipsychotics needs to be averted as they will exacerbate LBD symptoms.
LBD sufferers who are struggling from REM sleep conduct disorder can make the most of melatonin or clonazepam.
