  • THE CLINICAL ASSESSMENT of the PATIENT with EARLY DEMENTIA S Cooper, J D W Greene V15
    J Neurol Neurosurg Psychiatry: first published as 10.1136/jnnp.2005.081133 on 16 November 2005. Downloaded from THE CLINICAL ASSESSMENT OF THE PATIENT WITH EARLY DEMENTIA S Cooper, J D W Greene v15 J Neurol Neurosurg Psychiatry 2005;76(Suppl V):v15–v24. doi: 10.1136/jnnp.2005.081133 ementia is a clinical state characterised by a loss of function in at least two cognitive domains. When making a diagnosis of dementia, features to look for include memory Dimpairment and at least one of the following: aphasia, apraxia, agnosia and/or disturbances in executive functioning. To be significant the impairments should be severe enough to cause problems with social and occupational functioning and the decline must have occurred from a previously higher level. It is important to exclude delirium when considering such a diagnosis. When approaching the patient with a possible dementia, taking a careful history is paramount. Clues to the nature and aetiology of the disorder are often found following careful consultation with the patient and carer. A focused cognitive and physical examination is useful and the presence of specific features may aid in diagnosis. Certain investigations are mandatory and additional tests are recommended if the history and examination indicate particular aetiologies. It is useful when assessing a patient with cognitive impairment in the clinic to consider the following straightforward questions: c Is the patient demented? c If so, does the loss of function conform to a characteristic pattern? c Does the pattern of dementia conform to a particular pattern? c What is the likely disease process responsible for the dementia? An understanding of cognitive function and its anatomical correlates is necessary in order to ascertain which brain areas are affected.

  • A Model Based Approach to Apraxia in Parkinson's Disease
    A Model Based Approach to Apraxia in Parkinson’s Disease by Lauren King A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Master of Science in Kinesiology Waterloo, Ontario, Canada, 2010 © Lauren King 2010 AUTHOR'S DECLARATION I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii ABSTRACT This thesis provides new insight into how learned skilled movements are affected in a disease with basal ganglia damage, within what task demands these deficits can be detected, and how this detection can occur within the constraints of primary motor symptoms. Hence the purpose of this thesis was threefold. Firstly, the aim was to take a model-based approach to apraxia in PD, in order to determine the nature of the errors in reference to other populations that experience apraxia. Apraxia by definition cannot be the product of primary motor deficits, weakness, sensory loss, or lack of comprehension, therefore the second objective of the study was to detect apraxia while remaining true to these prerequisites. The third objective was to extend the examination of apraxia beyond the upper limbs, and investigate the relationship between upper limb and lower limb apraxia, as well as the relationship between freezing (which shares similarities with gait apraxia) and upper limb and lower apraxia. Overall, the most common pattern of apraxia identified in this PD group was impairment at both pantomime and imitation, suggesting issues with executive function.

TEL: +82 53-850-4668, FAX: +82 53-850-4359, E-mail: [email protected] Abstract. [Purpose] Ideomotor apraxia (IMA) is a disorder characterized by spatial or temporal errors in cor- rectly performing intentional movements and making meaningful gestures. This study was performed to determine whether the arm IMA scores can be used to predict the leg IMA scores using the IMA test for the upper and lower limbs. [Subjects and Methods] Thirty stroke patients that showed complete paralysis of a hemiplegic limb were recruited for this study. All patients were right-handed with no unilateral spatial neglect or severe cognitive impair- ment. IMA of the upper and lower limbs was assessed by the arm and leg IMA test. Each test has 12 items, which require patients to reproduce movements by imitation immediately after presentation using the limb ipsilateral to the lesion. [Results] The arm IMA test showed a significant correlation with the leg IMA test. The leg IMA score was predicted by the arm IMA score according to a simple regression model that showed a significant coefficient of simple determination. [Conclusion] We found that the score of the arm IMA test is similar to the score of the leg IMA test in hemiplegic stroke patients.
