Amarpreet Kaur, Nor Zuraida Z, Ng CG, Aida SA


Pathological laughing or crying (PLC) were recognized after the occurrence of stroke, with a prevalence of 15% to 18%. There is no apparent triggering stimulus, and is often misdiagnosed as a mood disorder as it is a disorder of emotional expression rather than a primary disturbance of feeling. We reported a case of a 32 year old lady, who presented with giddiness and altered consciousness progressing to fever and neck stiffness, who’s CT showed a massive left cerebellar infarct. No risk factors were identified. Psychiatrically, she developed sudden crying spells after one month and a diagnosis of Major Depressive Disorder was made with subsequent commencement of anti-depressants. A week later, she developed continuous inappropriate laughter without the feeling of elation, which was beyond her control. There were no symptoms of mania or psychosis.
