[Atypical neuroleptic malignant syndrome]

|May 1, 1994
Summary
A patient with obsessional neurosis developed a severe neuroleptic adverse reaction, including extrapyramidal symptoms and toxidermia, despite the absence of fever. This case highlights the complexity of differentiating neuroleptic malignant syndrome.
Area of Science:
- Neuroscience
- Psychiatry
- Clinical Pharmacology
Background:
- Obsessive-compulsive disorder (OCD) management often involves multiple psychotropic medications.
- Neuroleptic Malignant Syndrome (NMS) is a rare but serious adverse reaction to antipsychotic medications.
Observation:
- A 38-year-old male with a five-year history of obsessional neurosis experienced a severe breakdown.
- Treatment with multiple psychotropics, including haloperidol and fluvoxamine, led to extrapyramidal syndrome, toxidermia, and elevated creatine phosphokinase (CPK).
- The patient presented without hyperthermia, complicating the diagnosis.
Findings:
- The patient developed significant extrapyramidal symptoms (EPS), hypertonia, generalized shaking, and muscular atrophy.
- Skin lesions (bedsores, vesicular lesions) and markedly elevated serum CPK levels (12300 UI/l) were observed.
- Discontinuation of neuroleptics and anticholinergic treatment led to gradual but slow resolution of EPS and other symptoms.
Implications:
- This case underscores the challenges in diagnosing NMS, particularly when key features like hyperthermia are absent.
- The study suggests that elevated CPK and dermatological manifestations may occur in severe neuroleptic-induced reactions.
- Further research is needed to clarify the spectrum and diagnostic criteria for neuroleptic-induced severe adverse events.
