Abstract

fetched live from OpenAlex

OBJECTIVE:To describe symptoms suggestive of vascular parkinsonism (VP) in the last years of professor Charcot´s life. BACKGROUND:Jean-Martin Charcot (1825-1893) can be recognized as the founder of Neurology as well as the first teacher of nervous system diseases in a formal way. Charcot suffered from a chronic low back pain and attacks of angina pectoris. He died on the 16th August, 1893, due to acute pulmonary edema secondary to myocardial infarct. DESIGN/METHODS:Literature review RESULTS:Several papers and biographies about Jean-Martin Charcot demonstrated that he led an unhealthy life. Charcot had short stature, with obesity, and poor physical hygiene, sedentary, with strong appetite, chronic heavy smoker, combined with intensive intellectual activity. He suffered of chronic low back pain, and intermittent episodes of precordial pain, suggestive of coronary insufficiency, associated to anxiety. During a new year´s eve 1890 (Charcot was 65 years old) he had acute precordial pain, and professor Potain, a famous Parisian clinician, confirm the diagnosis of angina pectoris, and suggested the fatal outcome in two years. In the last years of Charcot´s life there were several descriptions of gait and posture disorder (shuffling of gait, with “petit pas” and a flexed posture of the trunk), mimicked Parkinson´s disease. Interestingly enough, there was no reference to the presence of upper limbs symptoms, suggesting the diagnosis of “lower-half parkinsonism”, due to cerebrovascular disease (VP). CONCLUSIONS:Professor Charcot probably had VP in the last years of your life, associated to others vascular problems (angina pectoris, probable cerebrovascular disease, and finally myocardial infarct). Study Supported by:

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
