Diagnosis

Differential diagnosis

Paroxysmal laughter: Laughing obsessive-compulsive disorder patients often laugh for no reason, sometimes faint laughter does not show teeth, sometimes laughs more than mouth, every hour of episodes of laughter can be more than 10 times, each lasting 5-6 seconds. In the early stages of the disease, people often sneak a laugh, and gradually become more and more difficult to control. No matter when and when, or laughing or smiling, there is no scruples. This is a special psychiatric disorder caused by the coordination of the nervous system's excitation and inhibition processes. The unstable excitatory process causes the cerebral cortex to form a stubborn stagnant and inert excitatory lesion.

Idiot: I am seen in patients with schizophrenia. Because of the abnormal function of the brain, when you laugh, you can sneer alone or laugh. For youthful schizophrenia, smirking is an important feature. But this kind of emotional instability, sometimes suddenly converging smiles, serious expressions; sometimes it is laughable and embarrassing.

Smirking: It is a special sneer. More common in patients with brain hypoplasia and senile dementia. This kind of laugh is not self-made, without any stimulation, can appear under any circumstances, no emotional color, so the patient is often happy, but due to the influence of intelligent obstacles, facial expressions give people a feeling of stupidity, no infection force.
