Parkinsonism with myoclonus is rarely associated with infectious disease in adults. We present a 55-year-old man experiencing acute onset bilateral limb tremor, rigidity, and myoclonus with small-stepped gait, and skin rash involving the trunk and limbs, after a fever. Serum was positive for anti-Orientia tsutsugamushi immunoglobulin M antibody. Brain MRI revealed no abnormalities. The fever improved with oral doxycycline, and the parkinsonism and myoclonus improved with amantadine and clonazepam. This is a rare case of parkinsonism with myolonus associated with scrub typhus infection.

L-type calcium channel antagonists are uncommon causes of myoclonus, and the underlying mechanism remains unclear. Here, we report a case of parkinsonian syndrome with deterioration of preexisting myoclonus after nifedipine use. A 96-year-old woman was administered a single dose of sustained-release nifedipine for chest pain.

Segmental Brainstem Myoclonus (SBM) is a rare movement disorder characterized by rhythmic contractions of muscles innervated by brainstem segments. We report a 20-year-old patient with ADCK3-related spinocerebellar ataxia type 9 (SCAR9) presenting with sudden-onset myoclonic movements of the throat, tongue, and soft palate. Brain MRI showed stable findings, including dentate nucleus hyperintensities.

Background/objectives: Cardiac arrest may cause significant hypoxic-ischemic injury leading to coma, seizures, myoclonic jerks, or status epilepticus. Mortality is high, but accurate prognostication is challenging. A multimodal approach is employed, in which electroencephalography (EEG) forms a key part with several recognised patterns of prognostic significance.

A patient with reactivated varicella zoster virus (VZV) manifesting in the left-sided dermatome L3 and S2-S4 developed tonic spasms which morphed into myoclonic jerks, paresis, rigidity and hypoesthesia of the left leg. Later, stimuli-sensitive myoclonus progressed to affect the upper body and was accompanied by fever surges with high-frequency myoclonus, hypertensive derailment, dysphagia and other features of the brainstem with autonomic dysfunction. Cerebrospinal fluid tested positive for VZV, MRI showed no signs of myelitis and EEG was negative for epilepsy.
