The latency of the P300 auditory evoked potential (which measures processing speed and has been shown to accurately predict memory impairment [ 4]) has only been studied with PTH levels in chronic renal failure, and the last work on this topic, to our knowledge, was published in 1983 [ 5].
Indeed, abnormalities that are revealed by the TMT B, which measures processing speeds and set shifting, are remarkably consistent across all published studies on CADASIL including our current case [ 12].
With regard to the individual cognitive tests (which measure processing speed and executive function), there were no significant associations [ 65, 72, 74, 76], except for the NART (a measure of childhood IQ, which showed a negative association with neck muscle CSA [ 27].
He and his team used a technique called electroencephalography, or EEG, which measures brain processing along the scalp.
The Sensory Profile is a 125-item questionnaire which measures sensory processing in 6 different domains, including oral sensory sensitivity [ 34].
The PANSS and MADRS assess symptoms, and the BACS-SCT measures processing speed deficits which are assumed to be more direct or proximal manifestations of schizophrenia; therefore, the scores for these measures were designated as "exogenous variables" (predictors) in this study.
A number of the cognitive tasks were drawn from the Wechsler Adult Intelligence Scale-IIIUK (WAIS-III, 1998): Matrix Reasoning (assesses nonverbal inductive reasoning), Block Design (assesses spatial and constructional abilities), Digit Symbol Coding and Symbol Search (which measure information processing speed) and Letter-number Sequencing and Backward Digit Span (which assess working memory).
The researchers also collected data on participant performance on an implicit alcohol association test, which measures the automaticity of processing alcohol-related information.
In addition, the cerebellar component was associated with TMT-A, which measures visual search ability and processing speed.
8 Interestingly, increased demand for working memory is also associated with decreased processing speed. 1 9 The Paced Auditory Serial Addition (PASAT) test, which measures working memory with high processing speed requirements, is one of the most sensitive tests available to detect cognitive impairment in patients with MS and it shows good correlation with deficit progression.
At present, for instance, sensing urban change from the ground up occurs 'through new sensing technologies that depend on hand-held and remote devices through to assembling transactional data from online transactions processing which measure how individuals and groups expend energy, use information, and interact' ([2], p. 492) with respect to resources.
