To assess executive function in subjects who may have language problems, a non-verbal test of visual reasoning has been added. It uses a format somewhat similar to Ravens Progressive Matrices Raven et al. The ideational uency test has been validated in patients with head injury, where it was found to be more sensitive to impairment than other uency tests Crawford, Validation studies are currently underway in normal elderly and demented patients.
The tests are included in advance of published results, on the basis of their validity in other contexts and their brevity. They are inserted after the Similarities items questions and numbered a and b. Because of their provisional status, scores on these tests do not contribute to the total CAMCOG score, which remains unchanged. A separate executive function score may be derived by adding the scores on these two items to the scores on similarities and animal uency see p.
For this purpose, both ideational uency and animal uency are recoded, bringing the maximum executive function score to This study will provide norms on an unselected elderly population as well as data on large numbers of individuals with dementia. To date, British norms are available only on a very elderly cohort in Cambridge City aged over 75 years Huppert et al.
Data from these studies are presented in Tables 2 and 3. Although only one of the skills may be impaired, management of elderly patients with major neurocognitive disorder becomes both a problem for the family and a public health problem, in that elderly drivers should be evaluated.
Impaired driving skills are only one example of the negative debilitating effects of apraxia, but it is important to emphasize the general importance of evaluation of praxis, as one of the indicators of cognitive fragility among elderly patients. This may suggest that these items are related to stages of dementia. Regarding constructive praxis, there is a requirement for visual skills and motor planning.
Both cerebral hemispheres act towards accomplishment of constructive tasks. Errors are usually associated with right-hemisphere parietal lesions due to deficits of perception, while errors of execution are related to lesions in the left hemisphere.
Ideomotor apraxia is related to lesions in the parietal cortex of the left hemisphere, in the corpus callosum and in the basal ganglia.
Ideational apraxia is usually caused by severe disturbances in the temporal sequence of motor actions. Some tests such as the clock drawing test CDT and copying of pentagons are considered to be more complex because they involve organization and planning of the motor action in order to carry out the task and are also influenced by schooling level.
This explains the weak correlation between memory and praxis, since the same brain regions may not be involved in the same satisfactory performances. Chandra et al. In other words, from the time when neuronal loss occurs in the cortical region and basal ganglia participating in motor circuits , patients will present impairment of intentional execution of motor tasks. There may be impairment in the early stages of dementia syndrome.
Motor areas of the cortex send signals to the basal ganglia and these in turn replicate the motor signals that are transmitted to the parietal cortex. Any failure to communicate or send signals can cause apraxia. While memory disorders tend to dominate cognitive psychology and neuropsychology, praxis deficits have been placed in the background.
This often leads to difficulties in accurately interpreting the nature of motor disorders presented by patients with neurological and neuropsychiatric disorders.
These authors stated that such instruments would need to have high diagnostic accuracy and be fast and easily administered, and that praxis tests might be able to fulfill this purpose. Helmes 19 and Martinelli et al.
These authors also stated that this test of copying a pentagon is so important for evaluating cerebral dysfunction that it should be scored independently. These findings agree with those of the studies by Hazan et al.
Evaluation of apraxia among elderly people is a way of exploring the field of cognition as part of the diagnostic investigation of neurodegenerative diseases. It was found through the praxis subitems from CAMCOG that some patients, even those whose aging process is healthy, present some difficulties in performing such functions with accuracy.
One limitation of the present study was in relation to the severity of dementia. Moreover, we only evaluated the forms of praxis that are included in CAMCOG, which only considers three of the various types of apraxia, such as dynamic, myokinetic, gait, dressing, buccofacial, agnostic and diagnostic apraxia. Our contribution from the present study consists of the suggestion that cognitive screening tasks consisting of constructive praxis should be used i.
