About Dr. Procyshyn

My research interests are primarily in the psychopharmacology of schizophrenia. Some of my current projects include:

Antipsychotic polypharmacy in which we are studying prevalence, predictors, indicators and clinical outcomes associated with this relatively common prescribing practice that is not adequately supported by the literature or clinical practice guidelines;

Smoking and schizophrenia where we have and continue to investigate the relationship between tobacco consumption and antipsychotic treatment, self-reported motivations for why individuals with schizophrenia smoke, and predictors of starting to smoke in first episode patients;

The influence of serum lipids on clozapine’s clinical efficacy in which we are exploring possible mechanism(s) that underlie our previous work showing a positive correlation between serum triglycerides and clinical response to clozapine; and the metabolic effects of antipsychotics where we are investigating the acute and chronic effects of the atypical antipsychotics on alterations in glucose and insulin parameters.
