TL;DR: To ascertain if there is a motor defect of the non-paretic hand of apraxic patients, twenty patients were given a rapid finger tapping test and their performance was compared with the left hand performance of aphasic right hemiparetic non-apraxic controls, and the aptaxic group performed significantly slower than the control group, thereby giving support to Liepmann's hypothesis of Apraxia.

TL;DR: The impairment seen in the patient with crossed apraxia provides evidence for the fractionation of systems underlying hand preference and skilled movement, andinematic motion analyses of movement linearity, planarity, and the coupling of temporospatial aspects of movements substantiated the parallel impairments in RF and patients with LHApraxia.

TL;DR: This case demonstrates that an isolated lesion may cause memory loss without involvement of traditional structures associated with memory and may explain memory disturbances in other white matter disease such as multiple sclerosis and lacunar state.

TL;DR: It is demonstrated that the center of mass effect can be seen with bisection tasks and is greater in the vertical than in the horizontal dimension.

TL;DR: It is proposed that in conjunction with current diagnostic criteria, statistical modeling techniques using neuropsychological test performance should be leveraged to construct a system to classify AD/VaD spectrum dementia in order to test hypotheses regarding how mechanisms related to AD and VaD pathology interact and influence each other.
