Delusional parasitosis is characterized by the unshakeable belief of being infested with tiny (microscopic) insects. Patients spend much time trying to get rid of the bugs and suffer from these symptoms. Patients prefer to go to dermatologists because they have a strong conviction over the presence of a somatic disease and do not accept any psychiatric advice for their complaints. 'Folie a deux' or shared psychotic disorder (SPD) is a relatively rare syndrome, which has long attracted clinical attention. Delusional parasitosis is associated in 5-15% of SPD and can run within a family. We experienced delusional parasitosis as 'Folie a Deux' between a mother and her son and successfully treated them through early psychiatric intervention. We believe that attention should be drawn to DP with SPD.

ObjectiveWe investigated the neurocognitive deficits in schizophrenic patients with and without obsessive-compulsive disorder (OCD).MethodsWe grouped 27 patients as either obsessive-compulsive or non-obsessive-compulsive based on the presence of OCD. The two groups completed the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Positive and Negative Symptom Scale (PANSS), and Hamilton Depression Scale. The intelligence quotient (IQ) was tested using the Korean Wechsler Adult Intelligence Scale. The memory quotient (MQ) was tested using the Korean-Auditory Verbal Learning and Korean-Complex Figure Test. The executive intelligence quotient (EIQ) was determined using the Kims executive intelligence test (EXIT).ResultsTen of the 27 patients had OCD. The compulsion score of Y-BOCS was positively correlated with positive symptoms, negative symptoms, and the total scores of PANSS. The OCD-schizophrenia patients had higher IQs. No difference was found in MQ. Although the EIQ did not differ between the two groups, the OCD-schizophrenia patients performed better at the Stroop-interference and verbal fluency tests, which was highly dependent on executive function.ConclusionOur findings suggest that OCD may have a protective effect on some cognitive function, at least in relatively early stage of illness. Moreover, based on clinical, neurocognitive features, schizophrenia with OCD could be considered as a distinct subtype of schizophrenia.

ObjectiveThere have been few long-term studies that have assessed factors influencing treatment discontinuation and long-term outcome of schizophrenia in Korea. The present study aimed to evaluate factors affecting treatment discontinuation and treatment outcome, after 10 years, in patients with schizophrenia.MethodsAmong hospitalized patients between 1997 and 1999, 191 patients were given continuous follow-up service. We examined the clinical characteristics and outcome of patients who remained in treatment. Regression analyses were used to find any clinical factors affecting treatment discontinuation.ResultsOne hundred thirty-three patients (71.12%) discontinued the treatment. The treatment retention group contained more female patients, paranoid-type patients, patients who had shown self-harming behavior, patients receiving clozapine, and patients with good medication compliance. The recovery rate was 25%. However, 42.3% did not have gainful employment. Further, most patients couldn't live independently.ConclusionThe results show the importance of gender, patient behavior, medication, and medication compliance in predicting treatment discontinuation in patients with schizophrenia.

Progressive supranuclear palsy (PSP) is a neurodegenerative disease characterized by vertical supranuclear palsy and parkinsonian symptoms. The neuropsychiatric symptoms of PSP include anhedonia, depressed mood and cognitive impairment. Patients with PSP have an increased risk for developing depressive disorders within the next year. However, it is rare to find that major depressive disorder was the antecedent diagnosis of a patient who was later diagnosed with PSP. We present here a patient who suffered from PSP with repetitive falls, a masked face and dysarthria after developing a major depressive disorder.

Young male with history of brain disease or brain trauma may have higher tendencies to have abnormal results of multiphasic personal inventory test compared to young male without history of brain disease or brain trauma, suggesting that damaged brain may cause psychopathology in young male group in Korea.
