Summary

This chapter provides an overview of the three most common disorders likely to be encountered by geriatric providers. Together, tremors, parkinsonism, and gait disorders are common enough that nearly one in three patients in a geriatrics clinic may be affected by at least one of these disorders. Each section begins with definitions of each of the conditions, clinical phenomenology, and features, followed by practical treatment approaches and algorithms. In addition, when there is overlap between conditions (i.e., atypical parkinsonism), hallmarks and red flags of each condition will be highlighted to help to compare and contrast.

Hemiparkinsonism secondary to a vascular mesencephalic lesion is infrequent; these patients offer an exceptional opportunity to study neuropsychological alterations attributable to unilateral dopaminergic denervation, shedding light on the pathophysiology of cognitive disorders in early-stage idiopathic Parkinson's disease (PD). From the investigation of our case, we conclude that destruction of the right nigrostriatal pathway is accompanied by deficits in executive functioning and verbal/visual memory similar to those observed in many patients with early-stage idiopathic PD. The more complex neuropsychological dysfunction developed by other PD patients must therefore be related to the additional involvement of other brain structures. (JINS, 2013, 19, 1–6)
