neuropsychological functioning and affective distress in 83 MA-dependent
individuals. Abstinent (n = 25) and User (n = 58) groups were classified based
on MA-use during a year-long interval period and were matched for
demographic, psychiatric and MA-use characteristics. Findings revealed
disproportionate improvement in the Abstinent group in affective distress,
verbal fluency, information processing speed, and global cognitive functioning.
These findings provide support for partial recovery in cognitive functioning and
affective distress following periods of abstinence and are consistent with research
demonstrating neural recovery from MA damage in frontotemporal systems. |
