Abstract
OBJECTIVE: Mitochondrial disorders are caused by gene mutations in mitochondrial or nuclear DNA and affect energy-dependent organs such as the brain. Patients with psychiatric illness, particularly those with medical comorbidities, may have primary mitochondrial disorders. To date, this issue has received little attention in the literature, and mitochondrial disorders are likely underdiagnosed in psychiatric patients. DATA SOURCES: This article describes a patient who presented with borderline personality disorder and treatment-resistant depression and was ultimately diagnosed with mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS) 3271. We also searched the literature for all case reports of patients with mitochondrial disorders who initially present with prominent psychiatric symptoms by using MEDLINE (from 1948-February 2011), Embase (from 1980-February 2011), PsycINFO (from 1806-February 2011), and the search terms mitochondrial disorder, mitochondria, psychiatry, mental disorders, major depression, anxiety, schizophrenia, and psychosis. STUDY SELECTION: Fifty cases of mitochondrial disorders with prominent psychiatric symptomatology were identified. DATA EXTRACTION: Information about the psychiatric presentation of the cases was extracted. This information was combined with our case, the most common psychiatric manifestations of mitochondrial disorders were identified, and the important diagnostic and treatment implications for patients with psychiatric illness were reviewed. RESULTS: The most common psychiatric presentations in the cases of mitochondrial disorders included mood disorder, cognitive deterioration, psychosis, and anxiety. The most common diagnosis (52% of cases) was a MELAS mutation. Other genetic mitochondrial diagnoses included polymerase gamma mutations, Kearns-Sayre syndrome, mitochondrial DNA deletions, point mutations, twinkle mutations, and novel mutations. CONCLUSIONS: Patients with mitochondrial disorders can present with primary psychiatric symptomatology, including mood disorder, cognitive impairment, psychosis, and anxiety. Psychiatrists need to be aware of the clinical features that are indicative of a mitochondrial disorder, investigate patients with suggestive presentations, and be knowledgeable about the treatment implications of the diagnosis.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
