OBJECTIVE To examine the baseline prevalence and longitudinal evolution in non-motor symptoms (NMS) in a prospective cohort of, at baseline, patients with de novo Parkinson's disease (PD) compared with healthy controls (HC). METHODS Parkinson's Progression Markers Initiative (PPMI) is a longitudinal, ongoing, controlled study of de novo PD participants and HC. NMS were rated using the Movemen...

We describe a case with complicated clinical presentations who was difficult to treat. We described the possible etiologies and differential diagnosis of neuroleptic malignant syndrome (NMS), catatonia, and infection, in details. This patient was also referred to neuro-intensive care unit for extensive workup and treatments by neurologist guidelines. In addition, we also used lorazepam-diazepam...

In Massachusetts, paralytic shellfish poisoning (PSP) is annually recurrent along the coastline, including within several small embayments on Cape Cod. One such system, the Nauset Marsh System (NMS), supports extensive marshes and a thriving shellfishing industry. Over the last decade, PSP in the NMS has grown significantly worse; however, the origins and dynamics of the toxic Alexandrium fundy...

SUMMARY Neuroleptic malignant syndrome (NMS) is a rare but life-threatening condition induced by neuroleptic medications. Its main symptoms include the rapid onset of fever, severe extrapyramidal symptoms, autonomic nervous system dysfunction, and impaired consciousness. In severe cases, acute renal failure and circulatory failure can develop, which can rapidly lead to death. In this case repor...

Neuroleptic malignant syndrome (NMS) is a rare but potentially fatal disease characterized by fever, muscle rigidity, delirium and autonomic instability. Here we report a child, with NMS due to the risperidone misdiagnosed as status epilepticus. Nine year old boy, who had been under high dose risperidone treatment for 8 weeks, admitted to the emergency room because of the contractions (evaluate...

We report a case involving an 81-tear-old man with schizoaffective disorder who presented with neuroleptic malignant syndrome (NMS) after an increase in his neuroleptic dose. NMS, a rare but potentially fatal complication of neuroleptic medications (e.g., antipsychotics, sedatives and antinauseants), is characterized by hyperthermia, muscle rigidity, an elevated creatine kinase level and autono...

This report aims at raising clinical awareness for the diagnosis of atypical presentations of neuroleptic malignant syndrome (NMS). We describe the case of a female patient with NMS symptoms, except fever, after starting the use of chlorpromazine. The afebrile condition delayed the consideration of NMS by the emergency clinicians who provided her initial assessment. Before this consideration, a...

Neuroleptic malignant syndrome (NMS) is a rare idiosyncratic reaction to antipsychotic drugs that is potentially fatal. Characteristic features of NMS are hyperthermia, muscular rigidity, severe autonomic dysregulation and disturbed consciousness. Signs and symptoms of serotonin syndrome (SS) can be grouped into four inclusive categories that are almost identical to those of NMS. Clinically, NM...

Neuroleptic malignant syndrome (NMS) is a rare idiosyncratic reaction to neuroleptic drugs, which is potentially fatal. It has been occasionally reported that NMS occurs subsequently after surgery. We report a case of a 53-year-old male patient who developed NMS following cardiac surgery due to the resumption of zotepine. The patient was attacked with hyperthermia, sweating, significant shiveri...

Monoiodinated, Met35-oxidized muscarinic toxin 7 (MT7ox) was synthesized, and its affinity constants for free or N-methyl scopolamine (NMS)-occupied hM1 receptor were measured directly by equilibrium and kinetic binding experiments. Identical values were obtained with the two types of assay methods, 14 pM and 0.9 nM in free or NMS-liganded receptor states, respectively, highlighting a strong ne...
