妄想症 Delusional Disorder

妄想症

是一種導致幻覺的精神疾病。它和其他精神疾病之間有一定差距，一個很顯著之處在於患妄想症者往往無精神分裂症病史，且沒有幻視產生（觸摸幻覺或味道幻覺可能會出現）。

患妄想症者可能外表很正常，也沒有奇異的行為（除非這些行為直接源於其妄想）。1999年，門羅（Munro）指出，「儘管妄想症患者的幻覺並不外露，且表現得似乎完全沒有影響，但其對於患者的影響是日益增加的。」

值得注意的是，「偏執狂」一詞曾被用於形容妄想症患者，但現在這一詞的含義已發生改變。

Delusional Disorder

A psychiatric diagnosis denoting a psychotic mental illness that involves holding one or more non-bizarre delusions in the absence of any other significant psychopathology (signs or symptoms of mental illness). In particular, a person with delusional disorder has never met any other criteria for schizophrenia and does not have any marked hallucinations, although tactile (touch) or olfactory (smell) hallucinations may be present if they are related to the theme of the delusion.

A person with delusional disorder can be quite functional and does not tend to show any odd or bizarre behavior aside from these delusions. "Despite the encapsulation of the delusional system and the relative sparing of the personality, the patient's way of life is likely to become more and more overwhelmed by the dominating effect of the abnormal beliefs". (Munro, 1999)

The term paranoia was previously used in psychiatry to denote what is now called 'delusional disorder'. The modern psychiatric use of the word paranoia is subtly different but now rarely refers to this specific diagnosis.

I think I have 妄想症.....because I keep thinking about Fiona Lao, someone I barely even know. This isn't good.
