Extract

Dr. Hughlings Jackson remarks that in every case of insanity there are negative lesions of the highest centres, which cause some paralysis, sensory or motor, or both (“Journal Mental Science,” October, 1888). Evidence that this is so has been brought forward by him, principally, however, in relation to the insanity of epilepsy and postepileptic states.

In the “Journal of Mental Science,” January, 1890, Dr. F. St. John Bullen states that atrophy of the brain was present in 67·5 per cent, of the cases. More or less of the entirety of the brain was affected in 36·7 per cent.; but in the cases where there were partial areas affected 46·0 per cent. show atrophy of the fronto-parietal lobes, or nearly one-half. The frontal lobes alone were affected in one-ninth, temporo-sphenoidal lobes in only two per cent., and the occipitals in 1·5 per cent. In 322 post-mortem examinations I found general atrophy in 53 per cent, of the cases, and in the cases where there was partial atrophy the fronto-parietal lobes were affected in 15 per cent. Temporal was not quite one per cent., and occipital not at all. The frontal lobes alone were affected in 8 per cent.Google Scholar
