Abstract

Participants were 61 children with ADHD and 60 healthy controls (boys and girls, ages 7-12). The ADHD children were diagnosed by an experienced psychiatrist to DSM-IV criteria, and have taken Ritalin for up to 6 months. None of the children in the control group had a history of psychiatric disorders, epilepsy, or any report of high-risk behaviors.

EEG recording was performed based on 10-20 standard by 19 channels (Fz, Cz, Pz, C3, T3, C4, T4, Fp1, Fp2, F3, F4, F7, F8, P3, P4, T5, T6, O1, O2) at 128 Hz sampling frequency. The A1 and A2 electrodes were the references located on earlobes.

Since one of the deficits in ADHD children is visual attention, the EEG recording protocol was based on visual attention tasks. In the task, a set of pictures of cartoon characters was shown to the children and they were asked to count the characters. The number of characters in each image was randomly selected between 5 and 16, and the size of the pictures was large enough to be easily visible and countable by children. To have a continuous stimulus during the signal recording, each image was displayed immediately and uninterrupted after the child’s response. Thus, the duration of EEG recording throughout this cognitive visual task was dependent on the child’s performance (i.e. response speed).

You are welcome

really precious to me specially in this pandemic situation. Thank You

In the description of the dataset it is written: "The eye movement was recorded by two electrodes that were placed below and above the right eye.", but there is no EOG in the download file. Are the EEG shared clean and without artifact (eye, etc.)?

Riccardo Asnaghi Thu, 10/08/2020 - 07:36 Permalink

It is corrected in description Raw EEG signal is published

Ali Motie Nasrabadi Thu, 03/04/2021 - 18:29 Permalink

Thanks a lot.

Radwa Rady Thu, 10/22/2020 - 14:14 Permalink

is this database only of people with adhd under treatment? Thanks

Miguel Rueda Diaz Fri, 10/30/2020 - 02:59 Permalink

Yes of course

Ali Motie Nasrabadi Thu, 03/04/2021 - 18:30 Permalink

Excuse me, which brand of EEG equipment was used to get the EEG signals ?

Kenneth Rodrig… Wed, 03/10/2021 - 16:02 Permalink

It was Chinese brand and I have not remembered the brand name

Ali Motie Nasrabadi Sun, 05/30/2021 - 05:37 Permalink

Thank you for uploading your dataset.

Saurav Bharadwaj Sun, 04/11/2021 - 19:25 Permalink

Thanks for sharing such a complete database. Can you kindly share the number of incorrect answers by each subject too?

Ali Kareem Fri, 04/16/2021 - 05:16 Permalink

Sorry it is inaccessible

Is there any difference between part 1 and part for both groups of normal control and ADHD? Does it mean that two parts of EEG data recorded in running different tasks (such as visual attention and mental activity)?

Jia-Rong Yeh Tue, 04/20/2021 - 01:20 Permalink

I hope it is game operated by key and brain operated game responses. Owner please confirm.

swapnali chaudhari Sun, 07/04/2021 - 11:15 Permalink

Please confirm

swapnali chaudhari Wed, 09/29/2021 - 18:02 Permalink

Thanks for sharing such a complete database. can you provide name of brand of EEG equipment was used to get the EEG signals ?

vandana joshi Tue, 04/20/2021 - 07:21 Permalink

Thanks for sharing. Is there any tag or mark in the data to know when the child's responses occured during the experiment?

Juan Andres Ro… Sun, 05/09/2021 - 16:48 Permalink

Sorry it is inaccessible We want to engage subject mental to the task and the response was not imporatant

Ali Motie Nasrabadi Sun, 05/30/2021 - 05:28 Permalink

Do the rows count time or blinks of an eye? and if it is time, is it measured in ms? thank you in advance

Hi Ali, first of all I want to thank you deeply for sharing your database. I'm currently working on my Phd and this database is very useful for me. Now I have a question, in the description of this page you wrote that the sampling frequency is 128Hz but in the paper " EEG Classification of ADHD and Normal Children Using Non-linear Features and Neural Network" you wrote that the sampling frequency is 256Hz. What is the sampling frequency of the data posted here? Thanks in advance. Best regards, Javier Sanchis

FRANCISCO SANCHIS Wed, 07/07/2021 - 15:31 Permalink

Hi Sampling Frequency for this data is 128 Hz

Ali Motie Nasrabadi Tue, 09/07/2021 - 12:01 Permalink

I will be very thankful if anyone can provide me this dataset in csv format. As I want to use it in python. I've tried alot to reach dataset related to ADHD and finally reached here. Please anyone??

Tahreem Fatima Sun, 07/25/2021 - 14:52 Permalink

You could try working with scipy.io to load them, following code works for me: import scipy.io mat = scipy.io.loadmat('ADHD_part1/v14p.mat') # print the keys of the dictionary to get further information on what's stored on mat variable print(mat.keys())

Sorry, I don't have this version.

Ali Motie Nasrabadi Tue, 09/07/2021 - 12:05 Permalink

thank you for this great Data set. if any one have a approach to open this data in python , please share it. thanks

hamid jahani Fri, 09/10/2021 - 16:20 Permalink

Hi May I know if there is some portion related to resting state EEG (Eyes close or Eyes open) in the beginning of each recording or its started directly from the task? Thank You

DANISH KHAN Sun, 09/26/2021 - 08:03 Permalink

Hi The released data was started in the beginning of the task

Ali Motie Nasrabadi Sat, 10/02/2021 - 16:10 Permalink

The dataset was really useful for my research. The channel number and its corresponding labels is provided, like Channel number 1 -> FP1. In the dataset, I considered the first column as FP1, 2nd column as FP2 values and so on. Is that right or is that in the order of 19 channels Fz, Cz, Pz, C3, T3, C4, T4, Fp1, Fp2, F3, F4, F7, F8, P3, P4, T5, T6, O1, O2? kindly clarify.

K Lakshmi Kalp… Sat, 11/27/2021 - 09:22 Permalink

What is difference between part1 and part2 ....

swapnali chaudhari Wed, 02/02/2022 - 13:31 Permalink

Thank you so much for providing the dataset which is going to be very helpful for my research. Can you please tell what is in standard file and how to open .ced file

Usha K Thu, 02/17/2022 - 04:41 Permalink

Thank you for sharing the data :) Is the trigger information available? I would like to know when you show the images and when the subject reponds during the task...

Julio Rodrigue… Wed, 11/02/2022 - 15:01 Permalink

What is the amplitude of ths signals? uV?

Hisham AL Ustwani Sat, 03/11/2023 - 10:43 Permalink

Do you have preprocessed data？ Or do you have EEG mark？

Yizhou Li Mon, 07/03/2023 - 05:11 Permalink

Hi Yizhou,
I also got confused about whether the data was pre-processed or not. Did you manage to get the preprocessed data?

Naji Naser Sat, 08/31/2024 - 12:51 Permalink

access to dataset please and how many subjects for this data !?

Baccouch Rawia Fri, 07/21/2023 - 19:26 Permalink

May I kindly inquire whether the researchers have utilized clinical assessment scales, such as Wanson, Nolan, and Pelham-IV, in their evaluation of the subjects in this dataset? If so, I would greatly appreciate it if there is a possibility to request access to these assessments

Yexian Zeng Wed, 10/11/2023 - 06:39 Permalink

Do the children with ADHD in this dataset vary in severity, or are they all collectively considered mild, moderate, or severe cases?

Jenna Wesely Tue, 09/17/2024 - 18:11 Permalink

what is the sampling frequency
