17 Neuropsychological impairment among methamphetamine users Decitabine solubility dmso Persons with bipolar disorder and individuals with HIV are at increased risk for both alcohol and other substance abuse and dependence2,18 The NP impairments associated with various drugs of abuse differ; however, most illicit substances and alcohol, when used in significant quantities or over

a substantial period of time, are likely to produce measurable Inhibitors,research,lifescience,medical neurocognitive deficits that may persist for extended periods, even after abstinence is achieved. Here, we focus on the neuropsychological difficulties associated with methamphetamine use disorders because: (i) its use is on the rise in the United States19; (ii) cognitive impairments are common and substantial among abusers; and (iii) it

is the most frequently abused substance, aside from marijuana and alcohol, worldwide.20 A recent review and meta-analysis showed that methamphetamine Inhibitors,research,lifescience,medical abuse or dependence resulted in neuropsychological impairments of medium effect size in the domains of episodic memory, executive functioning, information processing speed, motor Inhibitors,research,lifescience,medical skills, language, and visuoconstructive abilities.21 The cognitive domains with the largest effect sizes are listed in Table I. Furthermore, evidence suggests that when methamphetamine abuse or dependence is combined with HIV infection, there is additive neuropsychological impairment:22-23 Preliminary discriptive Inhibitors,research,lifescience,medical data on HIV-positive persons with bipolar disorder as compared with HIV-positive persons

without bipolar disorder We recently began prospective research studies in order to understand better the neuropsychological and everyday functioning (eg, medication adherence) difficulties among persons with bipolar disorder and HIV infection. Although these studies Inhibitors,research,lifescience,medical are ongoing and final results are not available, we show some of the descriptive data (Table II) for a group of HIV-positive (HIV+) bipolar disorder (BD) participants (HIV+/BD+) as compared with HIV+ persons without bipolar disorder (HIV+/BD-). Prospective bipolar participants were recruited for participation if they through reported a previous diagnosis of bipolar disorder and were currently taking medications to treat their bipolar disorder and HIV infection. A diagnosis of Bipolar I or IT was assigned by administering the gold standard psychodiagnostic assessment (Structured Clinical Interview for DSM-IV); alcohol and substance abuse and dependence diagnoses were determined via the Composite International Diagnostic Interview. Individuals with methamphetamine-induced mania were excluded. No other restrictions were placed on recruitment. Demographically similar (eg, age, education, ethnicity, sex, socioeconomic status) HIV+ comparison participants were recruited if they were taking a medication to treat their HIV illness.
