Clinical and diagnostic characteristics of Hashimoto's encephalopathy: a single-center, retrospective study.

Background And Purpose: Diagnosing Hashimoto's encephalopathy (HE) is challenging. In contrast to other types of autoimmune encephalitis, HE shows an excellent response to steroid treatment. We aimed to investigate the rates of antithyroid antibodies (ATAs) and probable HE in patients with unexplained mental dysfunction and compare the clinical characteristics between the good- and poor-outcome groups.

Herpes simplex encephalitis initially presenting without fever or cerebrospinal fluid pleocytosis and with typical neuroimaging findings: a case report.

Herpes simplex encephalitis (HSE) is a common viral encephalitis that can be fatal if not adequately treated. Fever, cerebrospinal fluid (CSF) pleocytosis, and typical neuroimaging findings are commonly observed in HSE cases. We encountered a patient with HSE who did not exhibit these classic clinical features.

Patient with Epilepsy Showing Psychiatric Symptoms after Remission of Seizures and Normalization of Electroencephalography: The Phenomenon of Forced Normalization?

Psychiatric disorders are commonly observed in patients with epilepsy. Among them, the phenomenon known as forced normalization is scarce. Herein, we report the case of a 41-year-old patient who showed long-term first-onset psychiatric symptoms after seizure remission and normalization of electroencephalography.

Anti-N-Methyl-D-Aspartate Receptor Encephalitis after BNT162b2 COVID-19 Vaccination.

After the coronavirus disease 2019 (COVID-19) pandemic emerged, the development of vaccines was accelerated. Neurologic complications of COVID-19 vaccination had been reported, which included encephalitis. In this study, we report a very rare case of a female with anti-N-methyl-D-aspartate receptor encephalitis associated with ovarian teratoma that would be triggered by BNT162b2 m-RNA COVID-19 vaccination.

Residual one-dimensional convolutional neural network for neuromuscular disorder classification from needle electromyography signals with explainability.

Background And Objective: Neuromuscular disorders are diseases that damage our ability to control body movements. Needle electromyography (nEMG) is often used to diagnose neuromuscular disorders, which is an electrophysiological test measuring electric signals generated from a muscle using an invasive needle. Characteristics of nEMG signals are manually analyzed by an electromyographer to diagnose the types of neuromuscular disorders, and this process is highly dependent on the subjective experience of the electromyographer.

Increased pulsatility index of the basilar artery is a risk factor for neurological deterioration after stroke: a case control study.

Background: Higher pulsatility of the middle cerebral artery (MCA) is known to be associated with stroke progression. We investigated whether pulsatility index (PI) of the basilar artery (BA) can predict neurological deterioration (ND) after acute cerebral infarction.

Methods: A total of 708 consecutive patients with acute ischemic stroke who had undergone transcranial Doppler (TCD) ultrasonography were included.

Incidence and mechanism of early neurological deterioration after endovascular thrombectomy.

Background: We investigated the prevalence and mechanisms of neurological deterioration after endovascular thrombectomy.

Methods: Between January 2011 and October 2017, acute ischemic stroke patients treated by endovascular thrombectomy in a tertiary university hospital were included. Early neurological deterioration (END) was defined as an increase of 2 or more National Institute of Health Stroke Scale (NIHSS) compared to the best neurological status after stroke within 7 days.

Eosinophilic Granulomatosis with Polyangiitis Presented as Acute Polyneuropathy and Cerebral Vasculitis.

Eosinophilic granulomatosis with polyangiitis (EGPA) is an immune related systemic disease that is caused by vasculitis affecting multiple organ systems. It is characterized by asthma, fever, eosinophilia, cardiac problems, renal injury, and peripheral neuropathy. In this report, we describe a patient with EGPA with concurrent cerebral infarction and acute polyneuropathy mimicking a Guillain-Barre syndrome (GBS).
