Introduction: The findings from different studies on neuropsychological
performance in anxiety disorders have identified a cognitive deficit
pattern comprising disorders of attention, executive function and
learning and memory processes. Objectives: To analyze the learning and
memory processes in the posttraumatic stress disorder (PTSD). Method:
Thirty patients with PTSD and 26 controls were evaluated. The Learning
Verbal Test España-Complutense (TAVEC), the subtests of letters and
numbers (L&N) and digits (D) of WAIS-III and the Rey Complex Figure
test were applied for the neuropsychological assessment; Results:
Patients with PTSD shown a less wide learning curve, lower consolidation
of information, with lower levels of free recall and discrimination
percentages; they benefited less from the semantic keys and tended to
retroactive interference. They also shown a lower score in working
memory, statistically different from the other group. In visual memory,
the performance was similar in both groups. Conclusions: Subjects with
PTSD show disorders in the process of consolidation and recovery of
information, involving the working memory, while short-term visual
memory performance is normal.
