AI in Parkinson's Disease: A Short Review of Machine Learning Approaches for Diagnosis

Revolutionizing Parkinson's Disease Diagnosis with AI

Arjita Sharma et al. – Published January 2026

This review synthesizes recent advancements in applying Machine Learning (ML) and Deep Learning (DL) to Parkinson's disease for diagnosis, progression prediction, and personalized treatment. It covers various data modalities including imaging, EEG, voice, gait, handwriting, emotion, and biomarkers, highlighting the potential for enhanced patient care and clinical outcomes.

Executive Impact

Our analysis highlights how AI is poised to transform Parkinson's disease management, offering significant advancements in early detection and personalized patient care.

The Core Problem Addressed

The primary challenge in Parkinson's Disease (PD) is the need for early and accurate diagnosis, alongside effective prediction of disease progression and personalized treatment strategies. Traditional methods often face limitations in detecting PD in its preclinical stages and tailoring interventions effectively.

The AI Solution: A Multimodal Approach

Artificial intelligence, through Machine Learning (ML) and Deep Learning (DL) models, offers a robust solution by analyzing diverse data modalities. This includes medical imaging (MRI, fMRI, SPECT), electroencephalography (EEG) signals, voice and speech patterns, gait and motion analysis, handwriting and drawing features, emotional and behavioral data, and genomic/biological markers. By integrating these varied data sources, AI can identify subtle, complex patterns indicative of PD much earlier than conventional methods, leading to improved diagnostic accuracy and enabling proactive, personalized treatment plans.

Voice/Speech Data Modalities for PD Diagnosis

Feature Type Key Benefits Limitations
Long-term Acoustic Features (Jitter, Shimmer)
  • Good for general disease presence detection.
  • Combines well with MFCCs.
  • Overfitting to language-specific properties.
  • Poor generalization across recording devices.
Time-Frequency Features (FrFT, Spectrograms)
  • Captures subtle vocal habits and dynamic changes, effective across languages.
  • High dimensionality increases complexity.
  • Relies on quality of sustained vowel phonation.
Speech Exercises (Tongue Twisters)
  • Highlights specific motor dysfunctions like dysarthria and hypomimia.

Real-time FoG Detection via Wearable Sensors

A study utilized a Multi-Head Convolutional Neural Network (CNN) with a single inertial sensor on the waist to detect Freezing of Gait (FoG) in Parkinson's patients. The system achieved 87.7% sensitivity and 88.3% specificity, predicting FoG episodes up to 3.1 seconds in advance. This demonstrates the potential for AI-enabled wearable devices in providing real-time interventions and improving patient safety, though further validation across diverse populations is needed.

  • Assay variability.
  • Small cohorts, overlapping biomarker distributions.
Proteomics/Metabolomics
  • High-dimensional patterns outperform single biomarkers; reveals early biological signatures.
  • Batch effects, overfitting.
  • Lack of external validation.
