AI Article Synopsis

  • A young man experienced acute akathisia and dystonia after accidentally overdosing on olanzapine (Zyprexa) following the recent discontinuation of fluoxetine.
  • An overview of the relevant receptor chemistry and mechanisms was provided, along with a literature review showing varying reports on the incidence of extrapyramidal effects from these medications.
  • The article recommends a careful diagnostic and treatment strategy for patients showing extrapyramidal symptoms, highlighting the importance of considering serious conditions like neuroleptic malignant syndrome and serotonin syndrome while stressing the need for clear discharge instructions to prevent complications.

Article Abstract

The patient with acute extrapyramidal signs and symptoms presents a significant clinical challenge. We present the case of a young man who developed an acute akathisia and dystonia after inadvertent overdose of olanzapine (Zyprexa) in the setting of a recent discontinuation of fluoxetine. The receptor chemistry and mechanisms pertinent to his presentation are reviewed. An analysis of the literature indicates that a broad incidence range is cited for the extrapyramidal effects of these medications. We suggest a diagnostic and therapeutic approach to the undifferentiated patient presenting with extrapyramidal signs and symptoms. The possibility of neuroleptic malignant syndrome (NMS), serotonin syndrome (SS), tricyclic overdose, and cocaine abuse should be considered in a patient with extrapyramidal signs and symptoms, given the potential for complications. An emphasis is placed on the need for carefully verbalized discharge instructions to avoid a potential untoward outcome.

Lysosomal storage disorders characterized by defective heparan sulfate (HS) degradation, such as Mucopolysaccharidosis type IIIA-D (MPS-IIIA-D), result in neurodegeneration and dementia in children. However, dementia is preceded by severe autistic-like behaviours (ALBs), presenting as hyperactivity, stereotypies, social interaction deficits, and sleep disturbances. The absence of experimental studies on ALBs' mechanisms in MPS-III has led clinicians to adopt symptomatic treatments, such as antipsychotics, which are used for non-genetic neuropsychiatric disorders.

Clinical Diagnosis and Differential Diagnosis Between CSF1R- and AARS2-Related Leukoencephalopathy.

J Mol Neurosci

January 2025

Department of Neurology, State Key Laboratory of Complex Severe and Rare Diseases, Peking Union Medical College Hospital, Chinese Academy of Medical Science/Peking Union Medical College, Beijing, 100730, China.

CSF1R-related leukoencephalopathy (CSF1R-L) and AARS2-related leukoencephalopathy (AARS2-L) were two disease entities sharing similar phenotype and even pathological changes. Although clinically, radiologically, and pathologically similar, they were caused by mutation of two different genes. As the rarity of the two diseases, the differential diagnosis of them was difficult.

Micrographia, characterised by small handwriting, is often linked to Parkinson's disease, but also resulted to injured brain lesions. The left-handed women in her 20s developed 'fast micrographia' after a traumatic brain injury from a traffic accident, showing bilateral subdural haematomas and frontal lobe contusions, but she had no paralysis and extrapyramidal symptoms. Neuropsychological tests showed reduced processing speed and memory deficits, aligning with frontal lobe damage.

Background And Objectives: A previous postmortem study of men with Christianson syndrome, a disorder caused by loss-of-function mutations in the gene , reported a mechanistic link between pathologic tau accumulation and progressive symptoms such as cerebellar atrophy and cognitive decline. This study aimed to characterize the relationships between neuropathologic manifestations and tau accumulation in heterozygous women with mutation.

Methods: We conducted a multimodal neuroimaging and plasma biomarker study on 3 middle-aged heterozygous women with mutations (proband 1: mid-50s; proband 2: early 50s; proband 3: mid-40s) presenting with progressive extrapyramidal symptoms.

Background: Metoclopramide, a dopamine antagonist employed for its antiemetic effects, can precipitate neuropsychiatric adverse effects, including extrapyramidal symptoms and, in a few instances, acute psychosis. Although there have been reports of metoclopramide-induced psychosis in elderly individuals, there is no documentation of such incidents in children as far as we are aware.

Case Presentation: This case report describes an 11-year-old girl with a history of mild intellectual disability and attention deficit hyperactivity disorder, managed with 10 mg of methylphenidate daily.
