Short-term neuropsychological outcome following Gamma Knife radiosurgery for arteriovenous malformations: a preliminary report.
This study investigated the effect of Gamma Knife radiosurgery for the treatment of arteriovenous malformations (AVMs) on neuropsychological functioning. We examined neuropsychological performance in 10 patients before and after radiosurgical treatment with the Leksell cobalt-60 Gamma Knife unit. The patients included 7 right-handed women and 3 right-handed men. ⋯ Pretreatment AVM diameter as measured on magnetic resonance scans ranged from 1.6 to 6.5 cm. After treatment, 2 AVMs disappeared, 4 decreased slightly in size, and 4 remained unchanged. We conclude that Gamma Knife radiotherapy in this sample of patients was neither detrimental nor beneficial to neuropsychological functioning.

Rey complex figure: memory error patterns and functional abilities.
The functional abilities of brain injured persons to live independently, were assessed using the Rancho Los Amigos Scale ratings of functional levels which were compared with memory error patterns on the Rey Complex Figure (Rey 1941) and the Recognition Trial developed by Meyers & Meyers (1995) Memory error patterns were described by Sohlberg & Mateer (1989), the least impaired memory error pattern was Retrieval, while Storage, Encoding and Attention patterns indicated greater defect Spearman rank order correlation revealed the strong association (r(S) = 86) of memory error pattern with Rancho Scale functional ratings In independent subjects 96 % achieved a Retrieval memory error pattern whereas 93% of subjects whose memory error pattern was poorer than a Retrieval pattern were unable to function independently Results indicate that patients obtaining a Retrieval (or better) memory error pattern may be expected to possess adequate cognitive resources for independent functioning.
