Abstract

Dementia with Lewy bodies (DLB) is the second most frequent neuropathologically diagnosed degenerative dementing illness. The clinical characteristics are progressive dementia, Parkinson syndrome, fluctuations of cognitive functions, vigilance and attention, visual hallucinations (usually detailed and well described), depression, REM-sleep behavior disorder, adverse responses to standard doses of neuroleptics, falls, syncopes, systematized delusions, and non-visual hallucinations. Mean age at disease onset ranges between 60 and 68 years. Male persons are more frequently affected than female. Disease duration is six to seven years. The differential diagnoses of DLB are dementia of the Alzheimer-type, Parkinson's disease, subcortical arteriosclerotic encephalopathy, progressive supranuclear palsy, multiple system atrophy, and, in rare cases, Creutzfeldt-Jakob disease. The genetic background of the disease is unclear. Magnetic resonance imaging and single photon emission tomography can contribute to the diagnosis. The disease is treated with L-dopa, atypical neuroleptics, acetylcholine esterase inhibitors, antihypotensive agents, and peripheral anticholinergic and alpha-receptor-blocking medicaments to improve neurogenic bladder d...Continue Reading

Alzheimer's Disease: Neuroimaging

Neuroimaging can help identify pathological hallmarks of Alzheimer's disease (AD). Here is the latest research on neuroimaging modalities, including magnetic resonance imaging and positron emission tomography, in AD.

Atypical Parkinsonism (MDS)

Atypical Parkinsonism presents with the same signs and symptoms of Parkinson's disease, but do not respond to typical Parkionson's disease treatment with levodopa. Atypical Parkinsonism is thought to be associated with abnormal protein buildup within brain cells. Here is the latest on Atypical Parkinsonism.

Antipsychotic Drugs

Antipsychotic drugs are a class of medication primarily used to manage psychosis (including delusions, hallucinations, paranoia or disordered thought), principally in schizophrenia and bipolar disorder. Discover the latest research on antipsychotic drugs here
