For the vignette, please give a diagnosis and bullet point the symptoms that made you come to the diagnosis. A 5-year-old male was brought by his grandmother with a history of recurrent abnormal body movement and shaking of his body. It was initially misconstrued as a seizure without the loss of consciousness for 3 days. It was of abrupt onset and a fluctuating pattern. The client had no history of drug usage such as antipsychotic or antiemetic that could cause abnormal body movement. There were intervals of normal movement and behavior. He was said to be having 4–5 episodes of abnormal body movements per day. There was no history of muscle spasms or seizures at any time. There was no history of use of anticonvulsant at any time and EEG done was normal. The physical and neurological examination done on him was normal. His cognitive functions and psychometric evaluations were normal. Laboratory results, including a full blood count, blood film for the malaria parasite, and blood chemistry (serum calcium, sodium, potassium, and bicarbonate), were essentially normal. He was sleeping well and was fully interactive and energetic in the ward. The child was initially managed as a case of dystonia and placed on IV fluid and diazepam 2.5 mg twice daily for 2 days. On the 3rd day, repeated abnormal body movement persisted even while walking without any falls. Despite his age, this was odd because of abnormal movement and gyration while walking without any fall which is not consistent with features of seizure disorder or dystonia. The need to consider interaction with the child was encouraged to explore a positive outcome. The child was then instructed to display that movement voluntarily, and to our amazement, he was able to display the movement repeatedly and was able to abort the movement voluntarily. He was able to repeat this symptom and abort severely when instructed. Further history at this point revealed that the child and grandmother had frequented kind of syncretic churches where worshippers fall into a state of religious trance, during which they gyrate their bodies rhythmically while delivering “spiritual” messages. On close discussion with the child, he revealed his perceived passion for the body movement learned from the spirit-filled worshiper in the church and the attention he gets from the grandmother when displaying such movement. Adopting a nonjudgmental approach and gentle persuasion, the client was encouraged to tell the full story, and he expressed the passion he has for such movement and dance. He enjoyed mimicking the abnormal body movement because of the attention he got from his grandmother any time he displayed it.

For the vignette, please give a diagnosis and bullet point the symptoms that made you come to the diagnosis. Kathy is a 32-year-old female who has had 17 prior admissions to acute care psychiatric facilities for suicide attempts and self-mutilation. She reported hearing voices and losing periods of time for which she could not account. She had alcoholic parents who exhibited violence toward each other and Kathy. They divorced when Kathy was 5 and she lived with her mother and a series of “stepfathers” who physically and sexually abused her. She was first hospitalized at age 13 following a Tylenol overdose. Shortly thereafter she refused to go to school and lived on the streets where she traded sex for food and shelter. Kathy was picked up by the juvenile authorities and spent the next 4 years in a residential program as a ward of the state. Her behavior improved with the structure; she completed high school and got a secretarial job. She married at age 20, but her husband reported that she was extremely moody and would often become hysterical during sex. Kathy began having “flashbacks” of sexual abuse and became extremely depressed. She was hospitalized repeatedly during the next 10 years receiving diagnoses of schizo-affective disorder, bipolar mood disorder and borderline personality disorder. Kathy had seen her current therapist for 6 months at the time of admission. A clinical interview revealed that Kathy often heard “mean voices in her head” and “children crying.” Kathy reported that she cut on her arms and abdomen to “relieve the internal pressure and stop the bad feelings.” Kathy said she frequently lost periods of time and would find herself in strange places not remembering how she got there. Upon request, the therapist was able to talk to an alter personality, Julie, who said that she helped Kathy during times of stress.
