Neurocognitive Functioning Following The PROMETA® Treatment Protocol In Subjects With Alcohol Dependence

The principal aim of this study is to extend our evaluation of the PROMETA® Treatment
Protocol as a means to improve neurocognitive functioning in recently detoxified alcohol
dependent subjects. For many alcohol dependent patients entering treatment, a range of
neurocognitive deficits are present that not only had adverse effects on the patient's
ability to function and think clearly but these deficits also impair the process of
addiction treatment. For example, alcohol dependent subjects typically experience high
levels of alcohol craving in the early stages of treatment. The patient is left with the
choice of relieving craving by drinking alcohol to provide immediate relief of craving
symptoms or abstaining from alcohol to obtain long-term benefits from recovery of the
complications from excessive drinking. We have previously shown in open label trials that
the PROMETA® Treatment Protocol helps stimulant abusers in the early stages of recovery,
have relatively low rates of relapse to stimulant use. It is not clear if the Protocol is
effective because of less urges to use stimulants or the ability to resist these urges is
improved from a recovery of Neurocognitive functioning. The present proposal extends our
previous research by comparing the efficacy of the PROMETA® Treatment Protocol in a double
blind placebo controlled trial using a new population of substance abusers (alcohol
dependent subjects) and assessing the effects of the PROMETA® Treatment Protocol on
neurocognitive functioning, particularly those aspects of functioning that affect the
ability to make decisions that have important long-term benefits.
