Cognitive deficits, especially verbal memory and executive functions were the strongest patients’ related factors associated with non adherence to medication. Psychiatrists ought to consider possible cognitive factors influencing adherence to enable offering proper interventions.

Medication non-adherence presents a considerable problem in patients with schizophrenia. Cognitive and executive functions can affect adherence. The association between medication non-adherence and cognitive impairment in schizophrenia is under investigated with limited and conflicting research data.To prospectively assess the rate of drug adherence among a sample of patients with schizophrenia and to compare the cognitive and executive functions between adherent and non-adherent patients.109 patients with schizophrenia diagnosed according to the DSM-IV classification were initially assessed by the Wechsler Adult Intelligence Scale (WAIS), Wechsler Memory Scale-Revised (WMS-R) and Wisconsin Card Sorting Test (WCST) and six months later by the Brief Adherence Rating Scale (BARS).68.8% were non-adherent to their antipsychotic medication. Adherent patients (31.2%) had significantly higher mean scores for the total, verbal and performance IQ. They had significantly higher mean scores in most of WMS subtests (orientation, information, verbal paired association, digit span, visual memory span), and higher mean scores for; total correct, conceptual level response, percentage and categories completed on the WSCT subscales (P < 0.0001). Whereas the non-adherent group had higher mean scores in; trials administered, total errors, perseverative responses, and perseverative errors (P < 0.0001). In a step regression analysis, digit span, conceptualization, total and percentage of errors were putative predictors of non-adherence.Cognitive deficits, especially verbal memory and executive functions were the strongest patients' related factors associated with non adherence to medication. Psychiatrists ought to consider possible cognitive factors influencing adherence to enable offering proper interventions.

[/quote]Yeah… about that. I want to see numbers & graphs, not just words before I start giving into such controversy.
That sounds like some dollar store baloney.
I found this interesting:
Adherent patients (31.2%) had significantly higher mean scores for the total, verbal and performance IQ.
Its not obvious what university / research center they were associated with… let me hunt around a bit to see if I can find out.
Hmmm - University of Cairo Egypt - not exactly the epicenter of schizophrenia research excellence. Lets see what the centers known for more rigorous academic centers say on this topic… we’ll post when it comes out.
