Original abstract
The experience of memory and retention weaknesses in Parkinsonian patients led us to question if these are only due to age-specific deteriorations, and if these weaknesses change during the L-Dopa therapy of the underlying disease. For this reason 30 Parkinsonian patients and 30 normal subjects of a matched control group took part in five different tests of retention and memory: digit span (Wechsler), visual retention test (Benton), Wechsler Memory Scale (subtests 4 and 7), delayed recall (Williams). The results (including some further samples of the test literature) gave some evidence of test-material-specific weaknesses in Parkinsonian patients: especially such memory decay as is dependent on the interval of retention. An organic deterioration of the intermediate term memory is suggested. This result could not be fully explained by known psychological or neurological characteristics of the underlying disease.
