Spontaneous remission of dropped head syndrome following short-term bed rest in acute encephalopathy: a case report.

Background: Dropped head syndrome is commonly observed in neurodegenerative disorders such as dementia with Lewy bodies. Its underlying causes include neck extensor myopathy and cervical dystonia. However, spontaneous remission of dropped head syndrome is extremely rare.

Atypical Frontal Release Signs in Acute Anterior Cerebral Artery Infarction and Striatal Dopaminergic Dysfunction: A Case Report.

Introduction: Dystonic hand postures are uncommon in patients with frontal lobe infarction. Here, we report the first case of a patient with frontal lobe infarction presenting with unique dystonic hand postures-specifically, a pointing gun posture and full-finger extension posture-in combination with frontal release signs.

Case Report: A 68-year-old man with a prior diagnosis of probable Parkinson disease acutely developed speech and communication impairment, along with reduced voluntary motor function in the right lower extremity.

Recurrent Positional Vomiting due to Cerebellar Infarction and Obstructive Hydrocephalus.

An 80-year-old woman presented with the sudden onset of vertigo and vomiting and was diagnosed with acute cerebellar infarction. Twelve days after the onset, she experienced positional vomiting, predominantly in the lying-down position, triggered by postural changes with immediate or delayed onset. Over 1 month, 23 episodes of vomiting occurred.

Duloxetine-associated parkinsonism in a patient with subclinical parkinson's disease: a case report.

Background: Duloxetine is a serotonin-norepinephrine reuptake inhibitor commonly used to treat depression and neuropathic pain. Duloxetine-associated parkinsonism has been previously reported in only two cases with psychiatric disorders. We present the first case where duloxetine unmasked motor manifestations of subclinical Parkinson's disease.

Deterioration of preexisting myoclonus following nifedipine use in parkinsonian syndrome: A case report.

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.

Posterior Interosseous Neuropathy with Peripheral Dystonia: A Case Report.

Background: Posterior interosseous neuropathy is an uncommon cause of peripheral dystonia.

Case Report: A 62-year-old man awakened and noticed right finger drop. A neurological examination revealed posterior interosseous neuropathy with dystonia-like finger movements.

Hand-foot synkinesis in a patient with phenytoin intoxication.

Here we report the first case of phenytoin intoxication that was closely associated with hand-foot synkinesis. This case suggests a close association between cerebellar dysfunction and hand-foot synkinesis. In patients with hand-foot synkinesis, lesions of not only the secondary motor areas but also the cerebellum should be considered.

Quadriplegia after ECMO therapy with sluggish recovery in a COVID-19 patient: A case report with a 14-month follow-up.

COVID-19 patients often develop neuromuscular complications, and critically ill patients often develop ICU-acquired weakness. We report a COVID-19 patient who developed flaccid quadriplegia after ECMO therapy and achieved a slow but consistent recovery during a 14-month period of sustained holistic rehabilitation including early mobilization to an outdoor environment.

Bilateral Vocal Cord Paralysis Associated with Meningeal Carcinomatosis from Lung Adenocarcinoma.

Cranial neuropathy is a clinical manifestation of meningeal carcinomatosis (MC); however, the glossopharyngeal and vagus nerves are rarely impaired. Therefore, dysphagia and bilateral vocal cord paralysis (BVCP) are extremely rare manifestations of MC. Here, we present a case of MC from a lung adenocarcinoma presenting with dysphagia and BVCP.

A case of chronic inflammatory demyelinating polyneuropathy following COVID-19 vaccine.

We report a 44-year-old woman who presented with bilateral weakness of the hands and distal paresthesia of the arms on the next day of the second COVID-19 vaccine, and gradually progressed ascending weakness of the arms and legs, and sensory ataxia beyond 2 months. She was diagnosed as a chronic inflammatory demyelinating polyneuropathy (CIDP) following COVID-19 vaccine on the basis of clinical and electrophysiological findings. This is a first case diagnosed as a CIDP following COVID-19 vaccine alone.

Occipital Neuralgia Secondary to C2 Spinal Cord Infarction.

We herein report the first case of occipital neuralgia secondary to spinal cord infarction. A 74-year-old woman suddenly developed numbness and dysmetria in her right arm. Two days later, she developed a paroxysmal shooting pain in the right posterior part of the scalp three to five times per day.

Index finger pointing posture in a patient with drug-induced foot tremor.

A 41-year-old woman who had been taking paroxetine began taking tramadol for bilateral ankle pain. A few days later, the patient presented acutely with both feet tremors. During a mental arithmetic task, index-finger pointing posture briefly appeared on the left side.

Impaired Motor Skill Acquisition Using Mirror Visual Feedback Improved by Transcranial Direct Current Stimulation (tDCS) in Patients With Parkinson's Disease.

Recent non-invasive brain stimulation techniques in combination with motor training can enhance neuroplasticity and learning. It is reasonable to assume that such neuroplasticity-based interventions constitute a useful rehabilitative tool for patients with Parkinson's Disease (PD). Regarding motor skill training, many kinds of tasks that do not involve real motor movements have been applied to PD patients.

Steroid Pulse Therapy May Mitigate Prolonged Neurological Manifestations after Eradication of Severe Plasmodium falciparum Parasitemia.

A 58-year-old Japanese man with a high parasitemia of Plasmodium falciparum, returning from Uganda, was admitted to our hospital since his consciousness level rapidly deteriorated after the initial dose of mefloquine. Despite the parasitemia was cleared by quinine by day 7, the coma remained unchanged and diffuse leukoencephalopathy was detected on magnetic resonance image. Steroid pulse therapy was initiated on day 8.

Transbrachial carotid artery stenting can prevent renal cholesterol embolism.

A 78-year-old man was admitted for the treatment of internal carotid artery stenosis. The left internal carotid artery was occluded and stenosis of the right internal carotid artery was progressive. The patient had a history of renal cholesterol embolism associated with percutaneous peripheral intervention.
