Parkinsonism is a clinical syndrome characterized by tremor, bradykinesia (slowed movements), rigidity, and postural instability. [1] [2] Both hypokinetic (bradykinesia and akinesia) as well as hyperkinetic (cogwheel rigidity and tremors at rest) features are displayed by Parkinsonism. [3]
Parkinson-plus syndromes are usually more rapidly progressive and less likely to respond to antiparkinsonian medication than PD. [10] [11] However, the additional features of the diseases may respond to medications not used in PD. [citation needed] Current therapy for Parkinson-plus syndromes is centered around a multidisciplinary treatment of ...
The diagnosis may initially be suspected in a person with rapidly progressing dementia, particularly when they are also found with the characteristic medical signs and symptoms such as involuntary muscle jerking, [35] difficulty with coordination/balance and walking, and visual disturbances. [4] Further testing can support the diagnosis and may ...
Dementia with Lewy bodies (DLB) is a type of dementia, a group of diseases involving progressive neurodegeneration of the central nervous system. [11] It is one of the two Lewy body dementias, along with Parkinson's disease dementia. [12] Dementia with Lewy bodies can be classified in other ways.

Eventually, mutism and progressive dementia set in. [2] Parkinsonism can be the first symptom of the disease, and it is noteworthy that some FTDP-17 patients have been misdiagnosed with Parkinson's disease or sporadic progressive supranuclear palsy. However, in some families, the parkinsonism appears later in the progression of the illness or ...
The CDC said 1.7% of adults ages 65 to 74 reported a dementia diagnosis, a rate that increased with age. For those ages 75 to 84, the reported dementia rate was 5.7%.
DLB is diagnosed when cognitive symptoms begin before or at the same time as parkinsonism. Parkinson's disease dementia is the diagnosis when Parkinson's disease is well established before the dementia occurs; that is, the onset of dementia is more than a year after the onset of parkinsonian symptoms.
