- Abstract summary: We perform a systematic analysis of the detection ability for gender sub-groups in a multi-center setting of a previously developed ML algorithm.
We find significant differences in the PD detection ability for males and females at testing time.
We find significantly higher activity for a set of parietal and frontal EEG channels and frequency sub-bands for PD and non-PD males that might explain the differences in the PD detection ability for the gender sub-groups.

- Abstract: As the number of automatic tools based on machine learning (ML) and
resting-state electroencephalography (rs-EEG) for Parkinson's disease (PD)
detection keeps growing, the assessment of possible exacerbation of health
disparities by means of fairness and bias analysis becomes more relevant.
Protected attributes, such as gender, play an important role in PD diagnosis
development. However, analysis of sub-group populations stemming from different
genders is seldom taken into consideration in ML models' development or the
performance assessment for PD detection. In this work, we perform a systematic
analysis of the detection ability for gender sub-groups in a multi-center
setting of a previously developed ML algorithm based on power spectral density
(PSD) features of rs-EEG. We find significant differences in the PD detection
ability for males and females at testing time (80.5% vs. 63.7% accuracy) and
significantly higher activity for a set of parietal and frontal EEG channels
and frequency sub-bands for PD and non-PD males that might explain the
differences in the PD detection ability for the gender sub-groups.

Alzheimer's Disease (AD) detection has emerged as a promising research area that employs machine learning classification models.
We identify within-class variation as a critical challenge in AD detection: individuals with AD exhibit a spectrum of cognitive impairments.
We propose two novel methods: Soft Target Distillation (SoTD) and Instance-level Re-balancing (InRe), targeting two problems respectively.

Despite previous research, there remains a significant gap in understanding the function of sex in the process of brain aging in PD patients.
The T1-weighted MRI-driven brain-predicted age difference was computed in a group of 373 PD patients from the PPMI database.
In the propensity score-matched PD male group, brain-PAD was found to be associated with a decline in general cognition, a worse degree of sleep behavior disorder, reduced visuospatial, and caudate atrophy.

Using Signal Processing and Machine Learning Techniques [0.0]
Parkinsons Disease (PD) is a neurodegenerative disorder resulting in motor deficits due to advancing degeneration of dopaminergic neurons.
EEG indicates abnormalities in PD patients.
One major challenge is the lack of a consistent, accurate, and systemic biomarker for PD in order to closely monitor the disease with therapeutic treatments and medication.

Resting-state EEG (rs-EEG) has been demonstrated to aid in Parkinson's disease (PD) diagnosis.
In this work, we use rs-EEG recordings of 84 PD and 85 non-PD subjects pooled from four datasets obtained at different centers.
We propose an end-to-end pipeline consisting of preprocessing, extraction of PSD features from clinically validated frequency bands, and feature selection before evaluating the classification ability of the features via ML algorithms to stratify between PD and non-PD subjects.
