longitudinal study showed normal levels of episodic memory performance when assessed with a selective reminding list learning test (Pitel et al., 2009). Although there is evidence for recovery in selective episodic memory processes such as list learning, other component episodic memory processes such as associative learning can remain impaired even with long-term abstinence (Brandt et al., 1983). To our knowledge, no study has been conducted to investigate cognitive recovery or improvement in semantic and cognitive procedural learning or in metamemory abilities with abstinence.
