Abstract
Pathological laughing and crying (PLC) is a condition defined by relatively uncontrollable episodes of laughter, crying or both. PLC is an uncommon symptom usually caused by cerebral lesions. Midbrain involvement causing PLC is extremely unusual and the exact mechanism by which this condition develops is poorly understood. We recently experienced a 51-year-old woman who were diagnosed as PLC after midbrain infarction. She was treated by acupuncture, pulsed electromagnetic therapy (PEMT). After 6 weeks treatment, Pathological Laughter and Crying Scale (PLACS), Korean version of the Scale for the Assessment and Rating of Ataxia (K-SARA) are decreased and Korean version of Modified Barthel Index (K-MBI) is increased. Treatment of traditional Korean Medicine could be effective for stoke rehabilitation including post-stroke PLC. And we have considered mechanism of PLC associated with midbrain lesion, dysfunction of cortex-thalamus-hypothalamus-basal ganglia-mesencephalon and faciorespiratory nuclei pathways, cerebro-ponto-cerebellar pathways and damaged serotonergic neurotransmission can cause this based on recent neurobiology of emotion. To define exact mechanism and find effective treatment, further studies are needed.
