Objective: To examine the relation of electroencephalographic abnormalities to 5-year outcomes in first-episode psychosis (FEP).

Methods: Patients (n = 103) had their baseline electroencephalogram (EEG) classified by modified Mayo Clinic criteria. Symptoms and psychosocial functioning were rated after 5 years of treatment.

Results: Dysrhythmic EEG was associated with persistence in positive and negative symptoms of psychoses and poorer psychosocial functioning at 5-year follow-up, independently of other characteristics, such as duration of untreated illness or premorbid adjustment. A higher percentage of people with comorbid substance use disorder had normal EEG.

Conclusions: Abnormal baseline EEG in FEP is associated with poorer 5-year symptomatic and functional outcome.

Background: Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) is clinically characterized by biphasic seizures associated with mild to severe neurological sequelae and is the most common subtype of acute encephalopathy in Japan, accounting for around 30 % of cases. The present study retrospectively analyzed the utility of electroencephalography (EEG) in determining the optimal method of diagnosing AESD at the early stage.

Methods: This study explores early power value differences to differentiate acute encephalopathy from prolonged febrile seizure (FS).

Objective: Sleep-related hypermotor epilepsy (SHE) is a relatively uncommon epilepsy syndrome, characterized by seizures closely related to the sleep cycle. This study aims to explore interictal electroencephalographic (EEG) characteristics in SHE.

Methods: We compared EEG data from 20 patients with SHE, 20 patients with focal epilepsy (FE), and 14 healthy controls, carefully matched for age, sex, education level, epilepsy duration, and drug-resistant epilepsy.

The literature suggests the existence of an association between autism spectrum disorders (ASDs) and subclinical electroencephalographic abnormalities (SEAs), which show a heterogeneous prevalence rate (12.5-60.7%) within the pediatric ASD population.

Hepatic encephalopathy (HE) in dogs is a metabolic disorder of the central nervous system that occurs secondarily to liver dysfunctions, whether due to acquired or congenital causes. A portosystemic shunt is the presence of abnormal communications between the hepatic vessels (portal and suprahepatic veins). As a result of this, the blood brought from the digestive tract through the portal vein bypasses the liver, and the unmetabolized components of the portal bloodstream enter directly into systemic circulation, causing clinical symptoms of metabolic encephalopathy (HE).

Parkinson's disease with dementia (PDD) and dementia with Lewy bodies (DLB) are more prevalent in males than females. Furthermore, they typically showed abnormally high delta (< 4 Hz) and low alpha (8-10 Hz) rhythms from resting-state electroencephalographic (rsEEG) activity. Here, we hypothesized that those abnormalities may depend on the patient's sex.
