Trial summary

Epilepsy with centrotemporal spikes (ECTS) is the most common epilepsy syndrome in children. Language impairment has been widely investigated in patients with ECTS, but little is known about the cognitive dysfunction of processing speed and its neuroimaging mechanism. Read more about this study

About this study

Official title: Association of Processing Speed Dysfunction and Brain Functional Abnormality in Childhood Epilepsy With Centrotemporal Spikes

Epilepsy with centrotemporal spikes (ECTS) is the most common epilepsy syndrome in children. Language impairment has been widely investigated in patients with ECTS, but little is known about the cognitive dysfunction of processing speed and its neuroimaging mechanism.

Read the detailed description

OBJECTIVE To investigate the processing speed dysfunction in patients with ECTS, and the associated brain functional abnormality using functional magnetic resonance imaging (fMRI) and 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET).

DESIGN, SETTING, AND PARTICIPANTS This study prospectively enrolled ECTS patients (n = 28) from June 2019 and June 2021. Twenty age- and gender- matched healthy children and another twenty children with extracranial tumors were enrolled as controls. Patients with ECTS and healthy controls underwent neuropsychological testing and fMRI examination. In addition, ECTS patients and children with extracranial tumors underwent 18F-FDG PET examination.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT04954729
Study groupRoleWhat they receive
Experimental GroupThe experimental group underwent neuropsychological testing, 18F-FDG PET/CT, 3T resting state fMRI examinations.
MRI Control GroupThe MRI control group underwent neuropsychological testing and 3T resting state fMRI examinations
PET Control GroupThe PET control group underwent 18F-FDG PET/CT examination

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Processing speed index

    Processing speed index was measured according to Wechsler Intelligence Scale for Children

    Measured: Through study completion, about 2 years

  2. Standardized uptake value ratio

    Standardized uptake value ratio was measured from 18F-FDG PET for brain glucose metabolism

    Measured: Through study completion, about 2 years

  3. Functional connectivity

    Functional connectivity was measured from fMRI for brain regional interactions

    Measured: Through study completion, about 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Epilepsy, Rolandic, run by Second Affiliated Hospital, Zhejiang University, School of Medicine at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Processing speed index (time frame: Through study completion, about 2 years). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04954729, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jul 2021.
