The Dopamine Transporter Scan (DaT) is a radionuclear imaging technique which was approved by the FDA to differentiate essential tremor (ET) from Parkinson's disease (PD). The scan is a crude indicator of the number of dopamine-secreting cells and is abnormal in presynaptic parkinsonian syndromes. In this article we review this and other possible clinical situations in which a DaT scan may be useful.

Background: As most patients are likely to first interface with their community general practitioner (GP) or geriatrician for chronic healthcare conditions, these non-neurologists practitioners are well-placed to diagnose, initiate treatment in symptomatic Parkinson's disease (PD) patients, and provide regular and timely management of their PD. However, current studies suggest that the role of the GP and geriatrician in providing holistic care for PD patients may be limited by factors such as patient perceptions, and a lack of knowledge base in the quality measures of care. This paper aims to better understand the different management styles between GPs and geriatricians practicing in public institutions in Singapore, qualify the difficulties they face in providing patient-centric care for PD patients, and identify any gaps in quality measures of care.

Neurologists are proficient in neuroanatomy and -physiology but their understanding of neurochemistry tends to be mediocre. As a rule, we do not think in biochemical pathways and complex metabolic interactions but rather associate a few neurotransmitters with well-known brain diseases or drugs that we routinely prescribe. Most of us can hardly come up with more than a handful of relevant neurochemicals.
