History
- British Psychiatrist, Dr. John Todd, coined "Todd's Syndrome" in 1955
- Patients with severe migraines experienced skewed perceptions
- No patients had a mental illness or brain tumors
Alice in Wonderland
Scientific Method
A migraine variant with abdominal colic and Alice in wonderland syndrome
Current Cases
- Published in 1865
- Lewis Carroll had migraine problems
- Speculated using his own experiences to write this story
Observation: Subjects experienced distorted human perceptions
Hypothesis: These distorted perceptions are characterized by or results from severe migraines
Testable prediction: Use of nuclear medicine techniques to detect abnormal cerebral areas
Experiment/Observation: Changes in cerebral areas went back to normal once the "episode" disappeared
Treatment
Currently, there is no effective treatment
Most people "grow" out of it in their teen years
