Efficient Prediction of Vitamin B Deficiencies via Machine-Learning Using Routine Blood Test Results in Patients With Intense Psychiatric Episode.

Background: Vitamin B deficiency is common worldwide and may lead to psychiatric symptoms; however, vitamin B deficiency epidemiology in patients with intense psychiatric episode has rarely been examined. Moreover, vitamin deficiency testing is costly and time-consuming, which has hampered effectively ruling out vitamin deficiency-induced intense psychiatric symptoms. In this study, we aimed to clarify the epidemiology of these deficiencies and efficiently predict them using machine-learning models from patient characteristics and routine blood test results that can be obtained within one hour.

Association of schizophrenia onset age and white matter integrity with treatment effect of D-cycloserine: a randomized placebo-controlled double-blind crossover study.

Background: It has been reported that drugs which promote the N-Methyl-D-aspartate-type glutamate receptor function by stimulating the glycine modulatory site in the receptor improve negative symptoms and cognitive dysfunction in schizophrenia patients being treated with antipsychotic drugs.

Methods: We performed a placebo-controlled double-blind crossover study involving 41 schizophrenia patients in which D-cycloserine 50 mg/day was added-on, and the influence of the onset age and association with white matter integrity on MR diffusion tensor imaging were investigated for the first time. The patients were evaluated using the Positive and Negative Syndrome Scale (PANSS), Scale for the Assessment of Negative Symptoms (SANS), Brief Assessment of Cognition in Schizophrenia (BACS), and other scales.

[An Adolescent Case of ASD Presenting with Persistent Catatonia and Epileptic EEG Discharge].

A 26-year-old man developed a catatonic state after his grandmother's death and the Great East Japan Earthquake. He was admitted to hospital because of the prolonged severe stupor. Electroencephalography (EEG) revealed focal (F3 electrode) and generalized epileptic abnormalities.

Sensorineural hearing loss associated with a factitious disorder.

Factitious disorders are characterized by intentionally abnormal physical and/or psychological behavior, and affected patients often make up their symptoms and clinical histories. The most serious and chronic type of factitious disorder is Munchausen syndrome. We report the case of a 24-year-old woman with a 2-year history of sensorineural hearing loss (SNHL) who later confessed to feigning her hearing loss.

Clinical course of the bipolar II disorder in a Japanese sample.

Background: The bipolar II disorder has been recognized a mental disorder distinctive from the bipolar I disorder, showing the stability of diagnosis in prospective studies. However, the characterization of the bipolar II disorder still remains under investigation.

Methods: The present study was conducted on consecutively admitted bipolar II inpatients diagnosed by DSM-IV-TR to delineate the clinical features.

Subgenual cingulate theta activity predicts treatment response of repetitive transcranial magnetic stimulation in participants with vascular depression.

Repetitive transcranial magnetic stimulation (rTMS) is an effective treatment for depression. Increased metabolism in the anterior cingulate cortex (ACC) is a known predictor for antidepressant response. The authors assessed whether increased theta power within the ACC predicts rTMS response in participants with vascular depression.

Correlation between denial of illness and executive function following stroke: a pilot study.

Executive function and denial of illness were examined among 24 patients who received double-blind antidepressant treatment following stroke. Between end-of-treatment at 3 months and follow-up at 2 years, significant correlation was found between improvement in executive function and decrease in denial of illness.

Effect of antidepressant therapy on executive function after stroke.

Background: Executive dysfunction is common after stroke and may impair long-term outcome. Remedies for this condition are limited.

Aims: To examine the effect of antidepressants on executive function after stroke.

Repetitive transcranial magnetic stimulation as treatment of poststroke depression: a preliminary study.

Background: Depression has a significant impact on poststroke recovery and mortality. There are a proportion of patients with poststroke depression (PSD) who do not respond to antidepressants. Repetitive Transcranial Magnetic Stimulation (rTMS) might be a safe and effective alternative in these refractory cases.

The effect of early versus late antidepressant treatment on physical impairment associated with poststroke depression: is there a time-related therapeutic window?

Impairments in activities of daily living (ADL) are common after stroke and may be related to poststroke depression. We have demonstrated that remission of poststroke major depression was associated with improvement in ADL. The administration of antidepressants within the first 3 months after stroke has been shown to prevent poststroke depression, early administration might also improve recovery of ADL among patients with stroke.

Does cognitive recovery after treatment of poststroke depression last? A 2-year follow-up of cognitive function associated with poststroke depression.

Objective: Cognitive impairment is common after stroke and may be caused by poststroke depression. Remission of poststroke major depression after treatment has been associated with improvement in cognitive function. The current study was designed to examine how long that cognitive improvement lasts and to compare depressed patients' cognitive status with that of nondepressed patients with comparable lesions.

Stroke-related depression.

Stroke represents a major health problem in the United States and most European and Asian countries. Depression is probably the most common and serious emotional disorder following stroke. Post-stroke depression (PSD) has frequently been overlooked and left untreated.

Preventing poststroke depression: a 12-week double-blind randomized treatment trial and 21-month follow-up.

This study examined the effect of antidepressants in preventing depression after stroke. Nondepressed poststroke patients (N = 48) were randomly assigned to receive nortriptyline, fluoxetine, or placebo for 3 months by using double-blind methodology and were followed-up for 21 months by using a naturalistic design. During the treatment period, one minor depression developed in the nortriptyline group (n = 13 at 3 months), one minor depression developed in the fluoxetine group (n = 13), and five minor depressions developed in the placebo group (n = 15; p <.
