The dentist has a large role in geriatric health care for the ever increasing elder population with associated physical and neurological disorders. The Parkinson disease is progressive neurological disorder with resting tremor, bradykinesia, akinesia, and postural instability. The psychological components of disease include depression, anxiety, and cognitive deficiency. Poor oral hygiene, incre...

A 77-year-old woman who was diagnosed with Parkinson disease at 51 years of age presented with a 4-year history of intermittent jaw tremor. This was present at rest and declined in amplitude during voluntary movements. Tremor reappeared after the patient bit a tongue depressor continuously for 10 seconds (video on the Neurology® Web site at Neurology.org). “Re-emergent tremor” is a postural han...

Movement disorders are a diverse group of hypokinetic and hyperkinetic neurologic diseases characterized by abnormal function of the basal ganglia. In this chapter, we will discuss the four most common diagnoses encountered in subspecialty movement disorders clinics: Parkinson disease, essential tremor, dystonia, and spasticity. The presentation and natural history of each of these disorders va...

Parkinson Disease is a neurological syndrome, characterized by resting tremor, reduced body movement and difficulty in maintaining proper posture. In this article I demonstrate a new method of parkinsonism diagnosis using Empirical Mode Decomposition (EMD) based on body movement synchronization analysis. EMD is a new method of signal decomposition into its monocomponents, so called Intrinsic Mo...

α-Synuclein is a key protein in Parkinson disease. Not only is it the major protein component of Lewy bodies, but it is implicated in several cellular processes that are disrupted in Parkinson disease. Misfolded α-synuclein has also been shown to spread from cell-to-cell and, in a prion-like fashion, trigger aggregation of α-synuclein in the recipient cell. In this mini-review we explore the ev...

The electrocardiogram is notoriously unreliable for the diagnosis of ischaemic heart disease in patients with Wolff-Parkinson-White syndrome. Abnormalities in the resting tracing may lead to false positive diagnoses of inferior or anterior myocardial infarction. Although ST segment depression with exercise has been reported in patients with Wolff-Parkinson-White syndrome, the depth of depressio...
