Dementia with Lewy bodies: a review.
The dementia with Lewy bodies (DLB) is the second major type of senile, degenerative dementia, after the Alzheimer disease (AD). It is characterized by the presence of cytoplasmic inclusions of alpha-synuclein in the cerebral cortex and in the nuclei of the brain stem. DLB patients frequently have complex visual hallucinations, depressive symptoms, Parkinsonian manifestations and cognitive deficits, showing important associations with the Parkinson disease and the AD. The DLB should be differentiated from atypical Parkinsonisms, but the differential diagnosis often remains difficult and unsafe. Clinical and neuropathological findings, as well as neuroimaging are valuable tools in establishing specific diagnosis of DLB. Acetylcholinesterase inhibitors, dopamine-agonists, benzodiazepines of short or medium half-life, and antidepressants may be useful in the treatment of DLB, depending on the dominant symptoms of the given patients.
