About This Dataset#

This dataset contains de-identified resting-state EEG recordings from individuals with Parkinson’s disease (PD) and age-matched healthy control subjects. All EEG data were recorded using standard clinical EEG systems at Neurology Clinic.

Dataset Purpose:

This dataset was originally used to evaluate whether resting-state EEG can help distinguish subjects who were later deceased from those who remained living (mortality classification). Only de-identified EEG data and mortality labels are included.

Participant Information: - Participants are labeled as either “living” or “deceased” in participants.tsv - No other demographic or clinical information (age, cognition, UPDRS, disease duration, etc.) is included per data-sharing guidelines. - All participant IDs are anonymized following BIDS convention (e.g., sub-PD1301).

EEG Acquisition Details: - Recording type: Resting-state EEG (eyes open) - Device: Clinical BrainVision EEG system

This dataset was originally used to evaluate whether resting-state EEG can help distinguish subjects who were later deceased from those who remained living (mortality classification). Only de-identified EEG data and mortality labels are included.

Participant Information: - Participants are labeled as either “living” or “deceased” in participants.tsv - No other demographic or clinical information (age, cognition, UPDRS, disease duration, etc.) is included per data-sharing guidelines. - All participant IDs are anonymized following BIDS convention (e.g., sub-PD1301).

EEG Acquisition Details: - Recording type: Resting-state EEG (eyes open) - Device: Clinical BrainVision EEG system - File formats: .vhdr, .eeg, .vmrk - Sampling rate: 500 Hz - Montage: Standard 10–20 international system - Recording condition: “task-rest” (no task)

Data Organization:

Data are structured following the BIDS (Brain Imaging Data Structure) EEG standard:
sub-<ID>/
ses-01/
eeg/

sub-<ID>_ses-01_task-rest_eeg.vhdr sub-<ID>_ses-01_task-rest_eeg.eeg sub-<ID>_ses-01_task-rest_eeg.vmrk

Mortality Label Format: - Living subjects: survival_status = “living” - Deceased subjects: survival_status = “deceased”

Ethics & Privacy:

All subjects provided consent for EEG recording at the University of Iowa Hospitals and Clinics. The publicly shared version here is fully de-identified and contains no clinical or personal health information other than mortality classification.

Suggested Use:

This dataset can be used to explore EEG biomarkers of mortality risk, EEG signal characteristics in PD, or to build machine learning models for classification.

NEMAR Processing Statistics#

The plots below are generated by NEMAR’s automated EEG pipeline. The histogram shows pipeline success for data cleaning and ICA decomposition, the percentage of data frames and EEG channels retained after artefact removal, line noise per channel (RMS, dB), and the age/gender distribution of participants.

Modality: eeg; Experiment type: Clinical/Intervention; Subject type: Parkinson's. Subjects: 94; recordings: 94; tasks: 1.

Parameters:

  • cache_dir (str | Path) – Directory where data are cached locally.

  • query (dict | None) – Additional MongoDB-style filters to AND with the dataset selection. Must not contain the key dataset.

  • s3_bucket (str | None) – Base S3 bucket used to locate the data.

  • **kwargs (dict) – Additional keyword arguments forwarded to EEGDashDataset.

data_dir#

Local dataset cache directory (cache_dir / dataset_id).

Type:

Path

query#

Merged query with the dataset filter applied.

Type:

dict

records#

Metadata records used to build the dataset, if pre-fetched.

Type:

list[dict] | None

Notes

Each item is a recording; recording-level metadata are available via dataset.description. query supports MongoDB-style filters on fields in ALLOWED_QUERY_FIELDS and is combined with the dataset filter. Dataset-specific caveats are not provided in the summary metadata.

Examples

>>> from eegdash.dataset import DS007020
>>> dataset = DS007020(cache_dir="./data")
>>> recording = dataset[0]
>>> raw = recording.load()
__init__(cache_dir: str, query: dict | None = None, s3_bucket: str | None = None, **kwargs)[source]#
save(path: str, overwrite: bool = False, offset: int = 0)[source]#

Save datasets to files by creating one subdirectory for each dataset:

path/
    0/
        0-raw.fif | 0-epo.fif
        description.json
        raw_preproc_kwargs.json (if raws were preprocessed)
        window_kwargs.json (if this is a windowed dataset)
        window_preproc_kwargs.json  (if windows were preprocessed)
        target_name.json (if target_name is not None and dataset is raw)
    1/
        1-raw.fif | 1-epo.fif
        description.json
        raw_preproc_kwargs.json (if raws were preprocessed)
        window_kwargs.json (if this is a windowed dataset)
        window_preproc_kwargs.json  (if windows were preprocessed)
        target_name.json (if target_name is not None and dataset is raw)
Parameters:

  • path (str) –

    Directory in which subdirectories are created to store

    -raw.fif | -epo.fif and .json files to.

  • overwrite (bool) – Whether to delete old subdirectories that will be saved to in this call.

  • offset (int) – If provided, the integer is added to the id of the dataset in the concat. This is useful in the setting of very large datasets, where one dataset has to be processed and saved at a time to account for its original position.
