Multiple Sclerosis (MS) is a chronic disabling neuroinflammatory disease. Psychiatric manifestations have a high prevalence in MS patients and may worsen the illness progression and the patients’ quality of life (QoL). Depression is a highly prevalent condition in MS patients, associated with poorer adherence to treatment, decreased functional status and QoL, and increased suicide risk. Diagnosis and treatment of this disorder is challenging because of symptom overlap. Other prevalent psychiatric comorbidities are anxiety disorders, bipolar disorder, psychotic disorders, substance misuse and personality disorders. As the illness progresses, personality changes can happen, as well as affect abnormalities. Cognitive changes occur frequently in MS patients, and affect features like processing speed, attention, learning, memory, visual spatial capabilities, and some language deficits. Disease-modifying treatments may reduce cognitive impairment because of their container action on the brain’s lesion burden. Other QoL determinants such as fatigue, pain, sexual dysfunction, exercise, resilience and social support should be taken into account, in order to promote the individuals’ well-being. Further studies are needed in order to elucidate the effectiveness of pharmacotherapy and more neuroimaging studies are required to clarify the relationship between structural changes and psychiatric comorbidities.

OBJECTIVE: Switching antipsychotics is one useful therapeutic option when the treatment of schizophrenia encounters suboptimal efficacy and intolerability issues. This study aimed to investigate the efficacy and tolerability of cross-tapering switching to ziprasidone from other antipsychotics. METHODS: A total of 67 patients with schizophrenia or schizoaffective disorder were recruited in this 12-week, multicenter, non-comparative, open-label trial. Prior antipsychotics were allowed to be maintained for up to 4 weeks during the titration of ziprasidone. Efficacy was primarily measured using the 18-item Brief Psychotic Rating Scale (BPRS) at baseline, 4 weeks, 8 weeks, and 12 weeks. Efficacy was secondarily measured by the Clinical Global Impression-Severity (CGI-S) scale and the Global Assessment of Functioning (GAF) scale at each visit. Regarding the metabolic effects of switching to ziprasidone, weight, body mass index (BMI), waist-to-hip ratio (WHR), and lipid profile-including triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and total cholesterol levels-were measured at each follow-up visit. RESULTS: The BPRS scores were significantly improved at 12 weeks after switching to ziprasidone (F=5.96, df=2.11, p=0.003), whereas the CGI-S and GAF scores were not significantly changed. BMIs, WHRs, and TG levels were significantly decreased, with no significant changes in other lipid profiles. CONCLUSION: Cross-tapering switching to ziprasidone is effective for patients with schizophrenia spectrum disorders. Beyond the efficacy of the procedure, favorable metabolic profiles show that switching to ziprasidone may be helpful for maintenance therapy over an extended period.

This paper aims to introduce, summarize, and emphasize the importance of the 'Evidence-Based, Pharmacological Treatment Guideline for Depression in Korea, Revised Edition'. The guideline broadly covers most aspects of the pharmacological treatment of patients in Korea diagnosed with moderate to severe major depression according to the DSM-IV TR. The guideline establishment process involved determining and answering a number of key questions, searching and selecting publications, evaluating recommendations, preparing guideline drafts, undergoing external expert reviews, and obtaining approval. A guideline adaptation process was conducted for the revised edition. The guideline strongly recommends pharmacological treatment considered appropriate to the current clinical situation in Korea, and should be considered helpful when selecting the appropriate pharmacological treatment of patients diagnosed with major depressive disorder. Therefore, the wide distribution of this guideline is recommended.

Cognitive deficit is frequently observed in patients with schizophrenia. It is significantly associated with functional outcome. In the past 20 years, due to significant advances on the concept of schizophrenia, cognitive deficit has been accepted as a core feature. In the DSM-5, cognitive deficit does not introduce diagnostic criteria of schizophrenia, but did one dimension of diagnosis of psychosis. Existing schizophrenia drugs are effective in treatment of positive symptoms of schizophrenia, but lack of effectiveness on improving cognitive function. Led by NIMH (National Institute of Mental Health), the MATRICS (Measurement and Treatment Research to Improve Cognition in Schizophrenia) meeting was conducted in order to achieve consensus on measuring tools and neuropharmacological targets for clinical trials for development of new drugs for improvement of cognitive function in schizophrenia. At the MATRICS consensus meeting, glutamatergic modulators and nicotinic and muscarinic agonists are expected to be promising, but should be proven by a double-blind placebo-controlled multicenter study for patients.

Methylenetetrahydrofolate reductase (MTHFR) deficiency is a rare autosomal recessive disorder. It is known that MTHFR deficiency may result in hyperhomocysteinemia, but MTHFR deficiency-induced schizophrenia has been rarely reported. Here we present the clinical course, biochemical and genetic characteristics of schizophrenia resulted from MTHFR deficiency in a school-age boy. He was 13 years old. He was admitted with a two-year history of fear, auditory hallucination, learning difficulty, sleeping problems, irascibility, drowsing and giggling. At admission, he had significantly elevated plasma and urine levels of total homocysteine, significantly decreased levels of folate in serum and cerebrospinal fluid, and a normal blood concentration of methionine. Further DNA sequencing analysis showed 665C>T homozygous mutations in the MTHFR gene. The patient was diagnosed with MTHFR deficiency-associated schizophrenia and treatment with calcium folinate, vitamin B12, vitamin B6, and betaine was initiated. After the treatment for 1 week, his plasma and urine levels of homocysteine were decreased to a normal range and the clinical symptoms were significantly improved. After 3 months of treatment, the patient returned to school. He is now living with normal school life. In summary, children with late-onset MTHFR deficiency and secondary cerebral folate deficiency may lead to schizophrenia. This rare condition can be early diagnosed through analyses of blood and urine total homocysteine, amino acids in blood and folate in blood and cerebral fluid and successfully treated with folinic acid, vitamin B6, vitamin B12 and betaine.

An 81-year-old woman with a history of temporal lobe epilepsy-induced psychotic episodes was initially admitted to a general hospital where she was started on a course of oral antibiotics for community-acquired pneumonia, and ciprofloxacin eye drops to treat nasolacrimal duct obstruction. After one week, the patient was discharged back to a nursing home with these medications. However, she was admitted to our psychiatric ward two days later due to a relapse of psychosis. Another six days later, she developed breakthrough seizures associated with subtherapeutic serum phenytoin levels. Having explored all possible causes of reduced serum phenytoin levels, ciprofloxacin eye drops was discontinued in the patient, resulting in gradual return of phenytoin levels to the therapeutic range, with no further seizures observed in the patient.

Behavioral and psychological symptoms in dementia (BPSD) are one of the common causes leading to significant impairment in quality of life for both patients and their caregivers, as well as an increased risk of institutionalization. In the treatment of BPSD, the first step is to check medical illness, and environmental status that can cause BPSD. When BPSD are associated with medical illness or environmental status, it is important to correct this condition for treatment of BPSD. However, if BPSD are very severe enough to be dangerous to patients or others and are not treatable by nonpharmacological approaches, pharmacological treatments could be considered. In pharmacological approaches, it is important to select relevant drugs according to the target symptoms, such as psychosis, depression, agitation, sleep disturbance, and so on. Due to the altered pharmacokinetics and pharmacodynamics, drug dosages for the patients with dementia should be started very low and increased slowly.

We describe herein an unusual case of subacute thyroiditis presenting as acute psychosis. An 18-year-old male presented at the emergency department due to abnormal behavior, psychomotor agitation, sexual hyperactivity, and a paranoid mental state. Laboratory findings included an erythrocyte sedimentation rate of 36 mm/hr (normal range, 0 to 9), free T4 of 100.0 pmol/L (normal range, 11.5 to 22.7), and thyroid stimulating hormone of 0.018 mU/L (normal range, 0.35 to 5.5). A technetium-99m pertechnetate scan revealed homogeneously reduced activity in the thyroid gland. These results were compatible with subacute thyroiditis, and symptomatic conservative management was initiated. The patient's behavioral abnormalities and painful neck swelling gradually resolved and his thyroid function steadily recovered. Although a primary psychotic disorder should be strongly considered in the differential diagnosis, patients with an abrupt and unusual onset of psychotic symptoms should be screened for thyroid abnormalities. Furthermore, transient thyroiditis should be considered a possible underlying etiology, along with primary hyperthyroidism.

INTRODUCTIONPolypharmacy is very common in the psychiatric setting despite the lack of evidence to justify its use. The objective of this study was to review the prescription patterns in a tertiary mental health institute in Asia and evaluate the impact of a treatment algorithm for patients with first-episode psychosis (FEP) on the use of polypharmacy.

MATERIALS AND METHODSA treatment algorithm was implemented for patients accepted into an Early Psychosis Intervention Programme (EPIP) and the prescription patterns of these patients were compared with a comparator group (pre-EPIP) before the use of the algorithm. The prescribing pattern was established at 2 points: at baseline after the diagnosis was made, and 3 months later.

RESULTSThere were 68 subjects in the comparator group and 483 EPIP patients; the latter were on the average younger. None in the comparator group was diagnosed to have an affective psychosis. There was a significant reduction in the rate of antipsychotic polypharmacy, prolonged use of benzodiazepines and anticholinergic medication in EPIP patients. This group also had an increase in the use of second-generation antipsychotics and received lower doses of antipsychotics.

CONCLUSIONThe implementation of a treatment algorithm coupled with audit has changed the trend towards polypharmacy among patients with FEP.
