RESUMEN
Apolipoprotein E (APOE) is a lipid transfer protein, which plays an important role in maintaining the stabilization of nerve and recovering. Alzheimer's disease (AD) is a neurodegenerative disorder. Most studies showed that APOE genotypes were closely related with AD. In clinical practice, AD is mainly manifested as progressive cognitive decline, and often accompanied by mental behavioral symptoms. These symptoms also exist in common severe mental illness. It is worth thinking about the correlation between APOE genotypes and these diseases. This article reviewed the relationship between the APOE genotypes and the common major psychosis.

RESUMEN
OBJECTIVES: The reliability and validity of the Korean version of Young Mania Rating Scale (K-YMRS) were examined in the Korean patients with major psychosis. METHODS: One hundred and twenty inpatients diagnosed as major psychosis by DSM-IV criteria were assessed with both K-YMRS and expanded Brief Psychiatric Rating Scale (BPRS-E) during the first 3 days in hospital and after 4-week treatment. RESULTS: The Cronbach's alpha coefficient of K-YMRS was 0.73. The inter-rater reliabilities of total score (r=0.93, p=0.000) and individual item scores were high (r=0.65-0.96, p=0.000). The correlations of each items of K-YMRS with total score were statistically significant (r=0.35-0.78, p=0.000) except for the "insight" item. The principal component analysis for K-YMRS produced three factors;a) mood and vegetative symptoms, b) behavioral symptoms, and c) thought content and insight. The total scores of K-YMRS showed a significant correlation with the manic-excitement factor scores of BPRS-E at baseline and after 4-week treatment (r=0.82, r=0.72, respectively, p=0.000). The discriminant function analysis showed that manic (n=43) and non-manic patients (n=73) were discriminated 73.7% correctly by K-YMRS total score (p=0.01). The change of the total score of K-YMRS after 4-week treatment in manic patients was significantly greater than that in non-manic patients (p=0.000). CONCLUSIONS: K-YMRS was demonstrated to have good reliability and validity for measuring the severity of manic symptoms. It is expected that K-YMRS will be a useful tool for assessing mania symptoms in Korea.
