Mental Disorder Diagnosis based on SPECT Scans using Machine Learning Oleksii Volkovskyi
Mental disorders rank 3rd on Disability Adjusted Life Years in the US 60% of adults with a mental disorder aren’t treated 1 in 5 adults in the US develop a mental disorder in a given year 2
In a study, depression was misdiagnosed 52.7% of the time by general practitioners Estimated total 40% misdiagnosis rate Incorrect treatment impairs emotional and physical abilities 3
Purpose Develop an algorithm for mental health disorder diagnosis based on single-photon emission computed tomography data using deep neural networks 4
Single-photon emission computed tomography (SPECT) ◎ A radioactive tracer is injected into the patient ○ iodine-123, technetium-99m, xenon- 133, thallium-201, and fluorine-18 ◎ Tracer flows through the bloodstream without being absorbed tissue cells ◎ Orbiting Camera (Computer Tomography) records gamma rays emitted by tracer ◎ Blood flow corresponds to intensity of brain activity ◎ Measures blood flow to regions throughout the brain ○ Spatial Resolution of about 10mm 5
Deep Neural Networks ◎ Task too complex for a naive algorithm ◎ A mathematical model ○ Comprised of computational nodes, each of which has a nonlinear functions ○ Consist of layers - input, intermediate, and output ○ Improve over training period ○ With a large dataset, neural networks are able to extrapolate knowledge 6
Procedure and Methods ◎ Task 1: Classifying General Mental Illness Type: ○ Anxiety ○ Psychotic ○ Eating ◎ Task 2: Classifying Between ADHD and Anxiety ○ Commonly misdiagnosed disorders ○ Differing treatments ◎ Dataset: Over 16000 data points ○ 600 numerical values per scan ○ Other characteristics like age, gender, and race ◎ Anonymous 7 ○ Mood ○ Dementia ○ Normal
Procedure and Methods ◎ Filled not recorded data values with column mean ◎ Standardised all of the values ◎ Training the Model: ○ Training/Validation (90%/10%) Data Split ○ 4 Dense Layers, 30 Computational Units per Layer ○ 1500 training iterations (2 hours) ○ Accuracy and Loss Logging ○ Overfitting 8
Results ◎ General Mental Disorder Classification ○ 99.1% Accuracy on Validation Data ○ 99.5% Accuracy on Training Data ◎ ADHD vs Anxiety Classification ○ 95.4% Accuracy on Validation Data ○ 97.6% Accuracy on Training Data 9
Conclusion ◎ Not always 99% accuracy, but much greater than 60% general correct diagnosis rate ○ Does not replace professional medical treatment, but instead serves as a second opinion to a professional ◎ Applications in Clinics ○ Pointing patients towards a specialized expert ○ More rigorous than questionnaires and polls ◎ Improvements ○ Larger Dataset allows a higher accuracy and allows for the use of more advanced algorithms 10

Mental Disorder Diagnosis using Machine Learning

  • 1. Mental Disorder Diagnosis based on SPECT Scans using Machine Learning Oleksii Volkovskyi
  • 2. Mental disorders rank 3rd on Disability Adjusted Life Years in the US 60% of adults with a mental disorder aren’t treated 1 in 5 adults in the US develop a mental disorder in a given year 2
  • 3. In a study, depression was misdiagnosed 52.7% of the time by general practitioners Estimated total 40% misdiagnosis rate Incorrect treatment impairs emotional and physical abilities 3
  • 4. Purpose Develop an algorithm for mental health disorder diagnosis based on single-photon emission computed tomography data using deep neural networks 4
  • 5. Single-photon emission computed tomography (SPECT) ◎ A radioactive tracer is injected into the patient ○ iodine-123, technetium-99m, xenon- 133, thallium-201, and fluorine-18 ◎ Tracer flows through the bloodstream without being absorbed tissue cells ◎ Orbiting Camera (Computer Tomography) records gamma rays emitted by tracer ◎ Blood flow corresponds to intensity of brain activity ◎ Measures blood flow to regions throughout the brain ○ Spatial Resolution of about 10mm 5
  • 6. Deep Neural Networks ◎ Task too complex for a naive algorithm ◎ A mathematical model ○ Comprised of computational nodes, each of which has a nonlinear functions ○ Consist of layers - input, intermediate, and output ○ Improve over training period ○ With a large dataset, neural networks are able to extrapolate knowledge 6
  • 7. Procedure and Methods ◎ Task 1: Classifying General Mental Illness Type: ○ Anxiety ○ Psychotic ○ Eating ◎ Task 2: Classifying Between ADHD and Anxiety ○ Commonly misdiagnosed disorders ○ Differing treatments ◎ Dataset: Over 16000 data points ○ 600 numerical values per scan ○ Other characteristics like age, gender, and race ◎ Anonymous 7 ○ Mood ○ Dementia ○ Normal
  • 8. Procedure and Methods ◎ Filled not recorded data values with column mean ◎ Standardised all of the values ◎ Training the Model: ○ Training/Validation (90%/10%) Data Split ○ 4 Dense Layers, 30 Computational Units per Layer ○ 1500 training iterations (2 hours) ○ Accuracy and Loss Logging ○ Overfitting 8
  • 9. Results ◎ General Mental Disorder Classification ○ 99.1% Accuracy on Validation Data ○ 99.5% Accuracy on Training Data ◎ ADHD vs Anxiety Classification ○ 95.4% Accuracy on Validation Data ○ 97.6% Accuracy on Training Data 9
  • 10. Conclusion ◎ Not always 99% accuracy, but much greater than 60% general correct diagnosis rate ○ Does not replace professional medical treatment, but instead serves as a second opinion to a professional ◎ Applications in Clinics ○ Pointing patients towards a specialized expert ○ More rigorous than questionnaires and polls ◎ Improvements ○ Larger Dataset allows a higher accuracy and allows for the use of more advanced algorithms 10
