标 题: 抑郁症有妄想表现吗？
发信站: BBS 未名空间站 (Wed Jan 21 14:54:12 2015, 美东)
张纯如精神障碍的正式诊断是抑郁症。根据美国精神病诊断权威标准DSM-5（附件1），
抑郁症是没有妄想表现的。也就是说，如果一个人被诊断为抑郁症，就不应该有妄想表
现。如果一个人有妄想表现，就不应该诊断为抑郁症。
那么确诊为抑郁症的病人是否可以出现妄想呢？回答是肯定的。但是，当一个抑郁症病
人出现妄想症状，原来的“抑郁症”就不再适用于病人。这种情况下就要改变诊断为“
精神病性抑郁症”。这种病人往往同时会出现幻觉症状。相应的治疗和保护措施也要作
出改变。相关学术依据见附件2。
有些人说张纯如有精神病。所谓的日本右翼极端势力对她不断发出暴力威胁其实是她的
妄想。起码从医生给她的正式诊断来看，张纯如没有妄想症状。

的一个例子，做为一道一小时完成的ECE qualify题目完全是有可能的。这个题叫做
First Occurrence of Successive Hits。
Let y_m 表示题目要求的，flip出m个head需要的平均次数（期望）。
To analytically get y_m，需要下面这个recurrence equation：
y_m = y_{m-1}/p + 1/p
初始条件，y_1 = 1/p (其实算出这个初始条件都不简单了，你需要知道 geometric
random variable 的特殊性质，不信你试试看。。。)
这题答案看上去很简单，但是要得到那个recurrence equation是很花时间的，要用到
expectation的很多高级性质，我估计LZ在简历说了自己概率或者数学很厉害什么的，
我很难想象面试能有这种题！！！面试官黑的漂亮！！！ |

发帖数: 10665 | 45 你这个要告的话，基本上没有希望能赢。
主要是PREXISTING的FILLING的大小和RECURRENT DECAY的大小，直接影响到
可能的结果。
如果以前的FILLING本身就比较大，而RECURRENT DECAY的SIZE也不小，那么
当DDS清理的时候，很有可能会很接近或者触到神经。
那么从FILLING变成ROOT CANNAL加CROWN的机率很大的。
通常如果DDS觉得有机会不需要做RCT的话，就会先做FILLING。而重新做的大的FILLING
后，有不少人都需要相当一段时间才能渐渐消除SENSITIVITY。我知道有人半年才好的
。当然如果一直很SENSITIVE，那么就要做RCT+CROWN了。
这是非常常见的情况。
另外，你要看的是ENDODONTIST不是ORTHODONTIST做RCT（根管治疗）。 |
