SUBACUTE INCLUSION ENCEPHALITIS: A CLINICAL AND PATHOLOGICAL REVIEW.
Canadian Medical Association Journal
|February 8, 1964
Summary
Subacute inclusion encephalitis is a rare neurological disorder. This study details 14 cases in Toronto, suggesting a probable viral origin despite unusual presentation and age predilection.
Area of Science:
- Neurology
- Virology
- Pathology
Background:
- Subacute inclusion encephalitis is infrequently reported in North America, with only 16 prior cases.
- The disease typically manifests as progressive cognitive decline, myoclonic seizures, and focal neurological deficits.
Purpose of the Study:
- To report on a series of 14 cases of subacute inclusion encephalitis encountered in the Toronto area over eight years.
- To analyze the clinical presentation, diagnostic findings, and potential etiology of this rare encephalitis.
Main Methods:
- Review of clinical data from 14 patients diagnosed with subacute inclusion encephalitis.
- Histological confirmation in seven cases.
- Analysis of electroencephalogram (EEG) and colloidal gold test results.
Main Results:
- 14 cases identified in Toronto over eight years, with seven histologically confirmed.
- Common symptoms include personality/intellectual deterioration, myoclonic seizures, and focal neurological deficits.
- EEG was characteristic in only nine cases, but colloidal gold tests were consistently abnormal.
Conclusions:
- The pathological features and lack of familial occurrence suggest a probable viral etiology for subacute inclusion encephalitis.
- The disease's rarity and specific age group predilection remain unusual characteristics.
- Further research is needed to understand the specific viral cause and epidemiological factors.
