Dr. Abigail Ortiz is Breaking New Ground with Mathematics
The Royal's Institute of Mental Health Research
2016-03-15
Dr. Ortiz’s research focuses on the subtle mood fluctuations in patients suffering from depression and bipolar disorder, which cannot be well documented using standard rating scales. Applying techniques related to chaos theory, she is using mathematical tools that have benefited neurology and cardiology patients to refine our understanding of mood regulation...

Borderline or bipolar? Using nonlinear analyses in clinical practice
University Medical Research Fund, University of Ottawa
2017-01-01
Principal Investigator: Dr. Abigail Ortiz
We will be using time-series analyses to analyze mood variability in both borderline personality disorder and bipolar disorder. We hypothesize these will be rather different and will serve as an extra clinical tool to aid in diagnostic clarification of these clinical entities.

An admixture analysis of the age at index episodes in bipolar disorder
Psychiatry Research2011
The interaction between polarity at onset (PAO) and age at onset (AAO) appears to be important for interpreting results of previous analyses of AAO in bipolar disorder (BD). Using an admixture analysis, we examined independently the distributions of age at first depressive and hypomanic/manic episodes in 379 BD I and II patients...
Treatment of bipolar disorder with comorbid migraine
Journal of Psychiatry and Neuroscience2010
A 43-year-old woman with bipolar type II disorder and comorbid migraine without aura had experienced recurrent depressive episodes since age 30 (some with complete, spontaneous recovery) and had taken various classes of antidepressants...
Cross‐prevalence of migraine and bipolar disorder
Bipolar Disorders2010
Objective: In two related studies, we explored the prevalence of migraine and its associated clinical characteristics in patients with bipolar disorder (BD) as well as psychiatric morbidity in patients treated for migraine.
Immune variations in bipolar disorder: phasic differences
Bipolar Disorders2007
Objectives: To characterize the immunological variations of patients with a bipolar disorder (BD) diagnosis in manic (BDm) and depressive (BDd) phases, by the quantification of the serum levels of interleukin (IL)-1β, -2, -4, -6 and tumor necrosis factor alpha (TNF-α).
A case of clarithromycin-induced manic episode (antibiomania)
The International Journal of Neuropsychopharmacology2004
Antimicrobial-induced mania, a rare but important side-effect of erythromycin and other drugs, is frequently under-recognized. Although its incidence – considering the wide use of antimicrobials – is statistically low, it should be regarded as a potential risk for patients both with and without a history of a mood disorder...
Nonlinear dynamics of mood regulation in bipolar disorder
Bipolar Disorders2016-12-14
Mood can be considered a memory stochastic process; it is a flexible, dynamic process that has a ‘short memory’ both in healthy controls and euthymic patients with bipolar disorder. This process may be quite different in untreated patients or in those acutely ill. Our results
suggest that nonlinear measures can be applied to the study of mood disorders.
